well, there are 28 + 28 + 24 = 80 pieces total, or namely that's the 100%, and we know that 24 of those are chocolates
[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} 80 & 100\\ 24& x \end{array} \implies \cfrac{80}{24}~~=~~\cfrac{100}{x} \\\\\\ \cfrac{ 10 }{ 3 } ~~=~~ \cfrac{ 100 }{ x }\implies 10x=300\implies x=\cfrac{300}{10}\implies x=30[/tex]
To figure out what percentage of the trail mix is chocolate, we add up all the pieces, divide the number of chocolate pieces by the total and multiply by 100. In this case, we find that 35% of the trail mix is chocolate.
Explanation:In order to figure out the percent of chocolate pieces in Caitlyn's trail mix, we first need to determine the total number of pieces. Caitlyn counts 28 raisins, 28 chocolate pieces, and 24 peanuts, which gives us a total of 80 pieces in the mix. Then, since there are 28 chocolate pieces, we divide 28 (chocolate pieces) by 80 (total pieces). This will give us the decimal representation of the portion of the mix that is chocolate. To convert this into a percentage, we multiply by 100. Hence, the calculation will be (28/80)*100 = 35%. So, 35% of the trail mix is chocolate.

4. Solve the triangle using either Law of Cosines or Law of Sines. In △DEF, f=25, e=8
and m∠F=131°.
Round your final answer to the nearest tenth. **
Angle D= Angle E= Angle d=
Answer:
Step-by-step explanation:
Using the Law of Cosines, we can find the remaining angle measures of the triangle.
Angle D = cos-1[(25^2 - 8^2 - (25^2 * cos(131°)))/(-2*8*25)] = 20.5°
Angle E = cos-1[(8^2 - 25^2 - (8^2 * cos(131°)))/(-2*25*8)] = 61.4°
Angle F = 180° - (20.5° + 61.4°) = 98.1°
Round to the nearest tenth:
Angle D = 20.5°
Angle E = 61.4°
Angle F = 98.1°
Two consecutive integers are such that 3 times the larger exceeds twice the smaller by 24. find the integers.
Answer:
26 and 27
Step-by-step explanation:
If the smaller integer is represented using the variable n, then the next consecutive integer is n + 1
3 times the smaller => 3n
2 times the larger => 2(n + 1 = 2n + 2
We are given 3 times the larger exceeds twice the smaller by 24 which can be represented as:
3n - (2n + 2) = 24
3n - 2n - 2 = 24
n - 2 = 24
n = 24 + 2 = 26
So the integers are 26 and 27

7.86x4.564 report the following answer into significant figures
Answer:
35.87
Step-by-step explanation:
First, what is 7.86 by 4.564?
It is 35.87304.
But the answer needs to be in significant figures, so how do we do that?
Well, significant figures are the numbers that comes after the decimal place. For example, 0.52, which has 2 significant figures.
So with 7.86, there are 2 significant figures and with 4.565, there are 3.
We want to use the one with the least amount of significant figures, so we would round our answer to the hundredth:
35.87
Hope this helps!
The required answer is 35.8730
The number of significant figures in a measurement represents the level of precision in that measurement. In general, the last digit in a number is considered uncertain and is rounded based on the number of significant figures.
When performing arithmetic calculations, the result should be rounded to the same number of significant figures as the least precise measurement used in the calculation.
In this case, the least precise measurement is 4.564, with four significant figures. Therefore, the final result of the calculation 7.86 x 4.564 should be reported with four significant figures.
The answer is 35.87304 and should be reported as 35.8730

A bank has launched a three-year structured deposit that offers an effective annual interest of 8% for the first 18 months, quarterly interest of 1.5% for the next 6 months and semi-annual interest of 2% for the last 12 months. If I wish to receive $100, 000 on the maturity date (that is, on the last day of the third year), how much, to the nearest dollar, should I invest? (Assume that interest rates and principal are guaranteed)
Answer:
To determine how much you should invest to receive $100,000 on the maturity date, you will need to calculate the present value of the cash flows at the beginning of the investment. The present value is the amount of money you would need to invest today to receive a certain amount at a future date, taking into account the time value of money and the interest rate.
You can calculate the present value by using the formula:
PV = CF / (1 + r)^t
Where:
PV = present value
CF = cash flow (the amount you will receive at the maturity date)
r = interest rate
t = time (in years)
The first 18 months, the interest rate is 8% per year, which is equivalent to 8/12 = 0.67% per month.
The next 6 months, the interest rate is 1.5% per quarter, which is equivalent to 1.5/4 = 0.375% per month.
The last 12 months, the interest rate is 2% per semi-annual, which is equivalent to 2/2 = 1% per month.
For the first 18 months, the present value of the cash flow is:
PV = 100,000 / (1 + 0.0067)^(18/12) = 95,167
For the next 6 months, the present value of the cash flow is:
PV = 95,167 / (1 + 0.00375)^(6/12) = 94,853
For the last 12 months, the present value of the cash flow is:
PV = 94,853 / (1 + 0.01)^(12/12) = 94,853
So, to receive $100,000 on the maturity date, you should invest 94,853 dollars to the nearest dollar.

What is the value of y that makes T Parallel to U
Answer: y = 18
Sentence: The value of y that makes T Parallel to U is 18.
Step-by-step explanation:
We are given 3 expressions:
(7x)(6y + 9)(3x + 36)We know that since the angle (7x) is on the same line as the angle (3x + 36), we can therefore determine that they correspond to each other. I referred an image to help demonstrate this concept. So since they correspond to each other, that means they have the same value (meaning they are equal to each other).
We can set both expressions equal to each other.
7x = 3x + 36
And solve:
7x = 3x + 36
-3x -3x
4x = 36
/4 /4
x = 9
now we know the value of x, we can plug it into one of the equations. We can plug it in to 3x + 36 to help with the process in solving y.
3(9) + 36 = 63 degrees
Since 6y + 9 and 3x + 36 (63 degrees) are supplementary angles, we can subtract 180 from 63.
180 - 63 = 117
now we know that 117 degrees = 6y + 9 BUT!, we need to solve for y, because that's what the question is asking for.
So lets solve for y:
117 = 6y + 9
-9 -9
108 = 6y
/6 /6
y = 18
converting within measurement sytems
Converting within measurement systems means that we are changing the unit of measurement from one to another.
What is Converting within measurement systems?It is referred to as converting units within measuring systems if we do it using the metric or conventional systems. The conventional system and the metric system are the two most widely used measurement systems. In other words, we are not converting units from customary to metric or vice versa.
Simple unit conversions can be performed mentally or with one-step multiplication or division. There are, however, more difficult conversions that call for many conversions between a wide range of units.
The Unit Factor Method, another name for the Dimensional Analysis process, is a mathematical technique that takes advantage of the fact that any number or statement may be multiplied by "one" without changing its value. By multiplying the previous measurement by one (or more) different representations of the number 1, you can convert units. Although the measurement's value is unaffected by the factor of 1, the measurement's units are.
A ratio of one is referred to as a conversion ratio or unit factor. The names of the units that will be used in the conversion are listed in this ratio. It can be used to convert values both within the English and Metric Systems and between the two. The idea of equivalent values serves as the foundation for the conversion ratio.

A checkout clerk at a department store is expected to complete 16 transactions every hour. In the past 20 minutes, he completed 6 transactions. Choose True or False for each statement. If the clerk continues at the same rate, he will meet his goal of 16 transactions in 1 hour. Choose... At his current rate, the clerk will complete 12 transactions in 1 hour. Choose... At his current rate, the clerk will complete 9 transactions every half hour. Choose... If the clerk continues at this rate for a 6-hour shift, he will complete 96 transactions. Choose...
Step-by-step explanation:
16 transactions per hour (60 minutes).
in short :
16/1
or 16/60 (for minutes instead of 1 hour)
in 20 minutes 6 transactions.
so,
6/20
hour many transactions then in 1 hour (60 minutes) ?
60 = 20×3
so, to bring the ratio to 1 hour (60 minutes) we need to multiply the denominator by 3. and to keep the ratio value, we need to to do the same thing also to the numerator.
therefore,
6/20 × 3/3 = 18/60
so, the clerk will do 18 transactions per hour.
he will meet his goal of 16 : true
he will even exceed but definitely meet his goal.
12 transactions in 1 hour : false
9 transactions every half hour : true
as he will do 18 transactions in 1 hour, he will do half of these transactions (9) in half an hour.
96 transactions in 6 hours : false
18/1
6 = 1×6
so, with the same trick as above we get
18/1 × 6/6 = 108/6
and we see, he would complete 108 transactions in a 6- hour shift.
96 would be right, if the actual ratio would be 16/1 :
16/1 × 6/6 = 96/6

The difference between two numbers is 9. Four times the larger number plus one-half the smaller is 45. What are the numbers?
Answer:
To solve this problem, we will use the following steps:
Step 1: Let's assume that the larger number is x and the smaller number is y, we know that the difference between the two numbers is 9, so we can write the equation: x-y = 9
Step 2: We know that Four times the larger number plus one-half the smaller is 45, so we can write the equation: 4x + 0.5y = 45
Step 3: Now we have two equations with two unknowns, we can solve for one of the unknowns by isolating it in one of the equations.
x-y = 9
x = y+9
Step 4: Now we can substitute the value of x in the second equation
4(y+9) + 0.5y = 45
4y + 36 + 0.5y = 45
4.5y + 36 = 45
4.5y = 9
y=2
Step 5: We can substitute the value of y in one of the equation, to find the value of x
x-2 = 9
x = 11
Final Answer: The two numbers are 11 and 2.

What are percentages?A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred.
The top diagram length is 60 units.
20 % of the 60 units is carried down, the length of the new section is:
20/100 * 60 = 12units.
60% of the next 12 units are carried down, the length of the new section is:

If BD=7x-10, BC=4x-29, and CD=5x-9, find each value
Answer: We know that in a triangle, the sum of the lengths of any two sides must be greater than the length of the third side.
Using the triangle inequality theorem, we can set up the following inequality:
BD + BC > CD
7x - 10 + 4x - 29 > 5x - 9
Simplifying, we get:
11x - 39 > 5x - 9
Subtracting 5x from both sides, we get:
6x - 39 > -9
Adding 39 to both sides, we get:
6x > 30
Dividing by 6 from both sides, we get:
x > 5
So x must be greater than 5.
To find the value of BD, we can substitute the value of x in the equation:
BD = 7x - 10
BD = 7(5) - 10 = 25 - 10 = 15
To find the value of BC, we can substitute the value of x in the equation:
BC = 4x - 29
BC = 4(5) - 29 = 20 - 29 = -9
To find the value of CD, we can substitute the value of x in the equation:
CD = 5x - 9
CD = 5(5) - 9 = 25 - 9 = 16
So, BD = 15, BC = -9, CD = 16

Triangle abc undergoes a sequence of transformations 1 reflection across line x=1. 2 dilation by a factor of 2 centered at the origin. What is the resulting image
The resulting image of the triangle ABC after the transformations is given by the image presented at the end of the answer.
How to obtain the image of the triangle?The vertices of the original triangle ABC are given as follows:
A(0,2), B(3,2), C (2,7).
First we have the reflection across the line x = 1, which is a vertical line, meaning that:
The x-coordinate remains the same distance from x = 1, however on an opposite direction.The y-coordinate remains constant.Hence the vertices after the reflection are given as follows:
A'(2,2), B'(-1,2), C'(0,7).
For example, a coordinate of 0 is one unit left of x = 1, hence the coordinate of the image will be one unit right, at x = 2.
The dilation with a scale factor of 2 centered at the origin means that the coordinates are multiplied by 2, hence:
A''(4,4), B''(-2,4), C''(0,14).

x + 12 = 0
x = - 12
x = - 12 ← is an excluded value in the domain
5
(2x - 1)(x + 6) = 0
equate each factor to zero and solve for x
2x - 1 = 0
2x = 1
x = [tex]\frac{1}{2}[/tex]
x + 6 = 0
x = - 6
x = - 6 and x = [tex]\frac{1}{2}[/tex] ← are excluded values in the domain
ayo earns 50,000 monthly and he spends 35,000 altogether. if he saves the rest, find the percentage of his savings
Answer:
30%.
Step-by-step explanation:
Ayo earns 50,000 monthly and he spends 35,000 altogether, so he saves the rest of his income. To find the percentage of his savings, we can divide his savings by his total income and multiply by 100.
His total income is 50,000
His total expenditure is 35,000
His savings = total income - total expenditure = 50,000-35,000 = 15,000
So the percentage of his savings = (savings / total income) x 100 = (15,000 / 50,000) x 100 = 0.3 x 100 = 30%
Therefore, Ayo's savings percentage is 30%.
