Andrew collects coins. He collected a total of 150 coins. If 76% of the coins he collected were foreign, how many other coins did he collect?
With percentage=76% of foreign coins of total 150 coins, Other coins collected were 36.
What is the percentage?
In mathematics, a percentage is a statistic or ratio that may be expressed as a fraction of 100. To find the percentage of a number, divide it by its total and multiply by 100. Hence, the percentage represents one part of a hundred. The phrase % stands for one hundred percent. It is represented by the symbol "%".
Here are some instances of percentages:
10% is one-tenth of a fraction.20% is one-fifth of a share.25% is divided into quarters.Now,
Given that total coins=150
Foreign coins=76% of total
then other coins are 24% of total
so other coins=150*24/100
=72/2

What are expressions exactly?
In mathematics, expressions are mathematical claims that consist of at least two sentences that contain numbers, variables, or both, and are linked by an operator in between. Mathematical operations include addition, subtraction, multiplication, and division. For instance, x + y is an equation in which the words x and y are separated by an addition operator. In mathematics, there are two types of expressions: numerical expressions, which include only numbers, and algebraic expressions, which contain both numbers and variables.
e.g. A number is 6 more than half of another number, x. This proposition can be stated mathematically as x/2 + 6. Mathematical expressions are used to answer complex problems.
Now,
Given that Total campers = 2375
and for each cabin there are 2 counselors and 50 campers
then no. of cabins = 2375/50
No. of counselors= 2*no. of cabins

why is it important to understand the concept of interest
It is important to understand the concept of interest beacause it is a part of our life and it hels us to understand the economic situation of ourselves.
What is simple interest?It is the interest calculated on the principal at a given rate for a time period.
We have.
There are two types of interest commonly studied.
1)
Simple interest
2)
Compound interest
Now,
Simple interest is the interest calculated only on the principal year after year.
Whereas compound interest is the interest calculated on the principal as well as the interest after the first year.
Example:
Principal = $100
Rate = 10%
Time = 2 years
Simple interest after two years.
= 2 x (10% of 100)
= 2 x (1/10 x 100)
= 2 x 10
= $20
Compound interest after two years.
Ist year:
= (10% of 100)
= (1/10 x 100)
= $10
2nd year:
= 10% of (100 + 10)
= 1/10 x 110
= $11
So,
= 10 + 11
= $21

Six years from today you need $10,000. You plan to deposit $1,500 annually, with the first payment to be made a year from today, in an account that pays a 5% effective annual rate. Your last deposit, which
will occur at the end of Year 6, will be for less than $1,500 if less is needed to reach $10,000. How large will your last payment be? Do not round intermediate calculations. Round your answer to the nearest
cent.
Answer:
Step-by-step explanation:
We can use the formula for the future value of an annuity to find the amount you'll have in the account at the end of Year 6. An annuity is a series of equal payments made at equal intervals of time, and the future value of an annuity is the amount you'll have in the future if you invest those payments and earn a given rate of interest.
The formula for the future value of an annuity is:
FV = PMT * (((1 + r)^n - 1) / r)
where:
FV = future value of the annuity
PMT = annual payment amount
r = annual interest rate as a decimal
n = number of payments
In this case:
PMT = $1,500
r = 0.05
n = 6
Plugging in the values:
FV = $1,500 * (((1 + 0.05)^6 - 1) / 0.05)
FV = $1,500 * (1.328867 - 1) / 0.05
FV = $1,500 * 0.328867 / 0.05
FV = $1,500 * 6.577340
FV = $9,865.61
So, the amount in the account at the end of Year 6 will be $9,865.61. To find the last payment, we subtract this amount from the desired future value of $10,000:
$10,000 - $9,865.61 = $134.39
Therefore, your last payment will be $134.39.

Suppose that Jenny, a college admissions officer for the Department of Mathematics at Smalltown University, is reading applications submitted by prospective students. The president of Smalltown University is weary about admitting too many domestic students and not enough international students. However, the applications are blinded so Jenny cannot see if an applicant is a domestic student or international student. Jenny is instructed by the president to admit exactly 20 applicants to the Department of Mathematics in a given year. Suppose that 38 domestic students and 42 international students applied to the Department of Mathematics at Smalltown University this year, and suppose that there is no difference in the qualifications of domestic and international students applying to Smalltown University.
Let represent the number of domestic applicants that Jenny selects this year. Calculate the mean, , and standard deviation, , of .
Please give the exact value for the mean and round your standard deviation to the nearest three decimal places.
The mean number of domestic applicants that Jenny selects is exactly 9.5, and the standard deviation is approximately 1.932
What is the standard deviation?Standard deviation is defined as the amount of variation or the deviation of the numbers from each other.
This is a problem involving a hypergeometric distribution since we have a fixed population (all applicants), two groups within the population (domestic and international students), and a fixed number of samples (20 students to be admitted).
Let X be the number of domestic applicants that Jenny selects this year. Then X follows a hypergeometric distribution with parameters N = 80 (total number of applicants), K = 38 (number of domestic applicants), and n = 20 (number of students to be admitted).
The mean of X is given by μ = nK/N, and the standard deviation of X is given by,
σ = √(nK(N-K)/(N²(N-1))).
Substituting the given values, we get:
μ = (20 x 38)/80 = 9.5
σ = √(203842/(80² x 79)) ≈ 1.932
Therefore, the mean number of domestic applicants that Jenny selects is exactly 9.5, and the standard deviation is approximately 1.932.

6. Ricardo Ramirez took out a single-payment loan for $2,500 at 7.8% ordinary interest to pay his federal income tax bill. If the maturity value of the loan was $2,548.75, in how many days would Ricardo have to pay back the loan?
Answer:
1. The monthly premium for workers' compensation insurance for the Winston Tree Farm and Nursery can be calculated as follows:
Monthly payroll: $3,560 Base rate: $5.93 per $100 Rate per $1,000: $5.93 * 10 = $59.30 Premium: $3,560 / 1,000 * $59.30 = $209.51
So, the monthly premium for workers' compensation insurance is $209.51.
2. The amount that Takis Machine Shop will pay each year for workers' compensation insurance can be calculated as follows:
Old base rate: $9.40 per $100 New base rate: $10.40 per $100 Monthly payroll: $53,896.84 Old rate per $1,000: $9.40 * 10 = $94.00 New rate per $1,000: $10.40 * 10 = $104.00 Old premium: $53,896.84 / 1,000 * $94.00 = $5,045.65 New premium: $53,896.84 / 1,000 * $104.00 = $5,610.71 Increase in premium: $5,610.71 - $5,045.65 = $565.06
So, Takis Machine Shop will pay an additional $565.06 each year for workers' compensation insurance.
3.The real estate tax for the home in Madison County can be calculated as follows:
Market value: $590,000 Rate of assessment: 40% of market value = $590,000 * 0.4 = $236,000 Tax rate: 42.73 mills = 0.04273 Tax: $236,000 * 0.04273 = $10,130.68
So, the real estate tax for the home in Madison County is $10,130.68.
4. The fair market value of Vanesa Vasquez's Roth IRA at age 65 can be calculated as follows:
Contribution: $2,500 Years of contribution: 65 - 35 = 30 Annual interest rate: 7.4% Future value: $2,500 * (1 + 0.074)^30 = $29,706.74
So, the fair market value of her Roth IRA at age 65 is $29,706.74.
The amount of interest earned can be calculated as follows:
Future value: $29,706.74 Present value: $2,500 Interest earned: $29,706.74 - $2,500 = $27,206.74
So, Vanesa Vasquez will have earned $27,206.74 in interest.
5. The interest rate as a percent for the GNMA Mortgage issue bond can be calculated as follows:
Face value: $10,000 Selling price: $10,000 * 103.7% = $10,370.00 Yield: 8.75% Price: $10,370.00 Interest: $10,370.00 - $10,000 = $370.00 Interest rate: ($370 / $10,000) * (12 / 1) = 0.09375 = 9.375%
So, the interest rate for the GNMA Mortgage issue bond is 9.375%, rounded to the nearest hundredth of a percent.
6. Let's call the number of days that Ricardo has to pay back the loan "d".
The interest on the loan can be calculated using the formula:
I = P * r * t
where I is the interest, P is the principal (the amount borrowed, $2,500), r is the annual interest rate as a decimal (7.8% as a decimal is 0.078), and t is the time in years (d divided by 365).
So we have:
I = $2,500 * 0.078 * (d / 365)
We also know that the maturity value of the loan is the sum of the principal and the interest:
$2,548.75 = $2,500 + I
So we can substitute for I:
$2,548.75 = $2,500 + $2,500 * 0.078 * (d / 365)
Expanding the right-hand side:
$2,548.75 = $2,500 + $194.00 * (d / 365)
And solving for d:
d = 365 * ($2,548.75 - $2,500) / $194.00
d = 365 * ($48.75) / $194.00
d = 365 * 0.25191780821917808
d = 91.37 days
So Ricardo would have to pay back the loan in 91.37 days.

if car traveling 40 mph takes 30 feet to stop, how many seconds will it take to stop? 
Answer:
To find the time it takes a car traveling at 40 mph to stop after covering a distance of 30 feet, we need to use the formula for distance, speed, and time, which is:
distance = speed * time
Rearranging the formula, we get:
time = distance / speed
Since the speed is in miles per hour (mph), we need to convert it to feet per second (fps). One mph is equivalent to 1.47 fps, so 40 mph is equivalent to 40 * 1.47 = 58.8 fps.
Now we can plug in the values for distance and speed into the formula:
time = 30 feet / 58.8 fps
time = 0.5104 seconds
Rounding to the nearest second, we get:
time = 0.51 seconds
So, it would take the car approximately 0.51 seconds to stop after traveling 40 mph.

Step-by-step explanation:
Given polynomial:
[tex]f(x)=-3x^3-5x^2+x-7[/tex]
Rational Root TheoremIf P(x) is a polynomial with integer coefficients and if p/q is a root of P(x), then p is a factor of the constant term of P(x) and q is a factor of the leading coefficient of P(x).
Possible p-values
Factors of the constant term: ±1, ±7
Possible q-values
Factors of the leading coefficient: ±1, ±3
Therefore, all the possible values of p/q:
[tex]\sf \dfrac{p}{q}=\dfrac{\pm1}{\pm1},\dfrac{\pm1}{\pm3},\dfrac{\pm7}{\pm1},\dfrac{\pm7}{\pm3}=\pm 1, \dfrac{\pm1}{\pm3},\pm 7, \dfrac{\pm7}{\pm3}[/tex]
Substitute each possible rational root into the function:
[tex]x=-1 \implies f(-1)=-3(-1)^3-5(-1)^2+(-1)-7=-10[/tex]
[tex]x=1 \implies f(1)=-3(1)^3-5(1)^2+(1)-7=-14[/tex]
[tex]x=-7 \implies f(-7)=-3(-7)^3-5(-7)^2+(-7)-7=770[/tex]
[tex]x=7 \implies f(7)=-3(7)^3-5(7)^2+(7)-7=-1274[/tex]
[tex]x=-\dfrac{1}{3} \implies f\left(-\dfrac{1}{3}\right)=-3\left(-\dfrac{1}{3}\right)^3-5\left(-\dfrac{1}{3}\right)^2+\left(-\dfrac{1}{3}\right)-7=-\dfrac{70}{9}[/tex]
[tex]x=\dfrac{1}{3} \implies f\left(\dfrac{1}{3}\right)=-3\left(\dfrac{1}{3}\right)^3-5\left(\dfrac{1}{3}\right)^2+\left(\dfrac{1}{3}\right)-7=-\dfrac{22}{3}[/tex]
[tex]x=-\dfrac{7}{3} \implies f\left(-\dfrac{7}{3}\right)=-3\left(-\dfrac{7}{3}\right)^3-5\left(-\dfrac{7}{3}\right)^2+\left(-\dfrac{7}{3}\right)-7=\dfrac{14}{9}[/tex]
[tex]x=\dfrac{7}{3} \implies f\left(\dfrac{7}{3}\right)=-3\left(\dfrac{7}{3}\right)^3-5\left(\dfrac{7}{3}\right)^2+\left(\dfrac{7}{3}\right)-7=-70[/tex]
As f(p/q) ≠ 0, none of the possible rational roots are actual roots of the given polynomial.

Find angle R
Find angle S
please help
In the cyclic quadrilateral the value of R and S are
< S = 87 degrees
< R = 216 degrees
How to find the value of R and SIn a cyclic quadrilateral, the opposite angles are supplementary hence
< S + < Q = 180
in the problem we have that < Q = 93
< S + 93 = 180
< S = 180 - 93
< S = 87 degrees
Angle R is adjacent angle to angles 126 and 90 hence we have that
< R = 126 + 90
< R = 216 degrees

Algebra 2, Exponental Funtction.
The numeric value of the exponential function at x = 19.5 is given as follows:
f(19.5) = 178.41.
How to model an exponential function?The standard definition of an exponential function is given as follows:
y = ab^x.
In which:
a is the initial value, the value of y when x = 0.b is the rate of change.Considering that f(4.5) = 25 and f(14) = 85, the two equations are given as follows:
ab^(4.5) = 25.ab^(14) = 85.Hence:
a = 25b^(-4.5).
Then the value of b is obtained as follows:
25b^(-4.5)b^(14) = 85.
b^(9.5) = 85/25
b = (85/25)^(1/9.5)
b = 1.14.
Then the value of a is obtained as follows:
a = 25 x (1.14)^(-4.5)
a = 13.86.
Then the function is defined as follows:
y = 13.86(1.14)^x.
At x = 19.5, the numeric value is given as follows:
y = 13.86(1.14)^19.5
y = 178.41.

Quadratic Expressions:Question 1
Which is a factor of x²+ 7x + 10?
Select one:
a x-5
bx-1
cx+5
dx+1
Answer:
Option C. (x + 5)
Step-by-step explanation:
This quadratic equation can either be solved using the quadratic formula or be factorised using The Double Bubble Method.
Double Bubble Method:
After listing the different pairs of factors 10, the pair (that would add together to give 7) are 2 and 5. These two factors will be used to rewrite +7x:
[tex]x^{2} + 2x + 5x + 10[/tex]
Factorization by grouping (i.e factorising each separate group sharing a common factor) will then be applied:
[tex]= x(x + 2) + 5(x + 2)[/tex]
The common factor, which is the (x + 2) expression, will be extracted:
[tex]= (x + 2)(x + 5)[/tex]
∴ [tex]x^{2} + 7x + 10[/tex] can be factorised to [tex](x + 2)(x + 5)[/tex]
It is observed that a factor of the given quadratic equation is x + 5
∴Option C

A hot-air balloon, headed due east at an average speed of 15 miles per hour at a constant altitude of 95 feet, passes over an intersection (see
the figure). Find an expression for its distance d (measured in feet) from the intersection t seconds later.
The expression for its distance d (measured in feet) from the intersection t seconds later is d = x + 79200 t (feet)
Finding expression for distanceSince the balloon is moving due east, we only need to consider its horizontal motion, ignoring its vertical motion at a constant altitude of 95 feet.
Let's call the initial distance of the balloon from the intersection x. The distance of the balloon from the intersection t seconds later can be found using the formula for distance traveled at a constant speed:
d = x + vt
where v is the speed of the balloon (15 miles per hour) and t is the time elapsed (in hours). To convert the speed from miles per hour to feet per second, we can multiply by the conversion factor of 5280 feet per mile:
d = x + (15 miles/hour) * (5280 feet/mile) * (t hours)
d = x + (15 * 5280) t feet
d = x + 79200 t feet
So the expression for the distance of the balloon from the intersection t seconds later is:
d = x + 79200 t (feet)
Note: In this expression, x represents the initial distance of the balloon from the intersection, which is unknown.
