Alice is saving money at a constant rate. Suppose she initially has $70 saved, and after 2 months, she has $170 saved.
Which of these expresses the rate at which Alice is saving?
Select the correct answer below:
50 dollars per month
70 months per dollar
−50 dollars per month
50 months per dollar
100 dollars per month
Answer:
50 dollars per month
Step-by-step explanation:
Given
[tex]Months = 2[/tex]
[tex]Total = 170[/tex]
[tex]Initial = 70[/tex]
Required
Determine the rate of savings
Suppose in a month, she saves x amount.
In 2 months, she would save 2x
When 2x is added to the initial savings, it gives the total amount saved.
So, we have:
[tex]2x + 70 = 170[/tex]
Collect Like Terms
[tex]2x = 170 - 70[/tex]
[tex]2x = 100[/tex]
Divide both sides by 2
[tex]x = \frac{100}{2}[/tex]
[tex]x = 50[/tex]
Hence, she saves $50 dollars monthly

WILL MARK BRAINLIEST Determine if each of the following are direct (D), Inverse (I), or neither (N). On the first blank, write the letter that corresponds with the variations. In the second blank, write the constant of variations. If the function doesn't have a constant of variations than leave the second blank empty. (PLEASE REFER TO PICTURE)
Answer:
A is neither, B is direct, and C is inverse
Step-by-step explanation
In B, as x increases y also increases, in C as x increases y decreases, and in A it's neither because it's not one line (if you graphed it you would understand what I mean). Though I have no idea what is constant of variations.

John rode his bicycle to school and back home. The distance from his home to school is 1.30 miles. What is the approximate number of kilometers that John rode? (1.00 kilometers = 0.62 miles)
Answer:
4.1935483871km
Step-by-step explanation:
Distance to and back = 1.3 miles *2 = 2.6miles
To convert kilometres to miles, multiply by 0.62. Therefore, to convert from miles to kilometres, divide by 0.62.
2.6/0.62=4.1935483871km

Coach Perez has 32 basketballs and 16 footballs. which ratio accurately compares the number of basketballs to the number of footballs?
Answer:
2:1 or 2/1
Step-by-step explanation:
the original ratio is 32:16 or 32/16
remember a ratio is like a fraction
as long as you divide both numbers by the same number, the ratio is still accurate
so in this case we will divide by 16 because it is the gcf
32 divided by 16 is 2
16 divided by 16 is 1
so the answer is 2:1 or 2/1
Find the sum. one ninth + one twelfth A. 7 over 36 B. six sevenths C. one over thirty-six D. 1 over 7h
plz help fast i am stuck. and thank you
12/14/2020
Answer:
A. 7 over 36
Step-by-step explanation:
One ninth =1/9
One twelfth = 1/12
1/9+ 1/12= 12+9/108
= 21/108
We can then reduce the fraction to the lowest denominator by dividing the numerator and denominator by 3
That will result in 7/36

A scientist is at spot that has Ang angle elevation of25.4' top 223 foot all observation
Complete question
A scientist is at spot that has An angle elevation of 25.4' top 223 foot all observation. How far is the scientist from the base of the observatory
Answer:
[tex]X\approx469.64[/tex]
Step-by-step explanation:
From the question we are told that
Angle of elevation [tex]\theta= 25.4'[/tex]
Height [tex]H=223[/tex]
Generally the equation for the Distance X is mathematically represented as
[tex]X=\frac{H}{tan\theta}[/tex]
[tex]X=\frac{223}{tan 25.4\textdegree}[/tex]
[tex]X=469.6369092[/tex]
[tex]X\approx469.64[/tex]
Therefore the distance is
[tex]X\approx469.64[/tex]

Answer:
Subtract to eliminate y
Step-by-step explanation:
it is the easiest to eliminate first since 7y and -7y are opposites.
I'm guessing this is one of those problems where u find both y and x .... but yeah its the 3 option
Answer:
Option 'C i.e. Subtract to eliminate y' is the correct option.
Step-by-step explanation:
Given the system of equations
-6x + 7y = -54
-7x + 7y = -56
The first step we need to do is to subtract to eliminate y, because 7y and -7y will cancel each other.
[tex]-6x + 7y = -54[/tex]
[tex]-[/tex]
[tex]\underline{-7x+7y=-56}[/tex]
x + 0y = 2
x = 2
Therefore, we get x = 2 after we implemented the fist step to subtract to eliminate y.
Hence, option 'C i.e. Subtract to eliminate y' is the correct option.

A computer’s random number generator produces random integers from 1 to 50. What is the probability that at least one of the first 4 generated numbers is in the 20s?
0.0016
0.1024
0.4096
0.5904
Answer:
0.5904
Step-by-step explanation:
For each number, there are only two possible outcomes. Either it is in the 20s, or it is not. The probability of a number being in the 20s is independent of other numbers. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
4 generated numbers:
This means that [tex]n = 4[/tex]
Probability of a number in the 20s:
From 1 to 50, there are 50 numbers. Of those(from 20 to 29), there are 10 in the 20s. So [tex]p = \frac{10}{50} = 0.2[/tex]
What is the probability that at least one of the first 4 generated numbers is in the 20s?
Either none is, or at least one is. The sum of the probabilities of these events is 1. So
[tex]P(X = 0) + P(X \geq 1) = 1[/tex]
We want [tex]P(X \geq 1)[/tex]. So
[tex]P(X \geq 1) = 1 - P(X = 0)[/tex]
In which
[tex]P(X = 0) = C_{4,0}.(0.2)^{0}.(0.8)^{4} = 0.4096[/tex]
[tex]P(X \geq 1) = 1 - P(X = 0) = 1 - 0.4096 = 0.5904[/tex]
A TV has a listed price of $800 before tax. If the sales tax rate is 8%, find the total cost of the TV with sales tax included. Round your answer to the nearest cent, as necessary. Show your work.
Answer:
The total cost of the TV with sales tax included is $864.
Step-by-step explanation:
In order to find the the total cost of the TV with sales tax included, you have to calculate the 8% of the listed price and add this amount to the price:
$800*8%=$64
$800+$64=$864
According to this, the answer is that the total cost of the TV with sales tax included is $864.

but we dont want 2/3 of a person so just ignore that part

Step-by-step explanation:
assuming that you can go up to 2500, simply multiple until you reach your target of 2500, i did 150 x 16 to get 2400, 100 less than 2500, meaning it would be safe and one more wouldn't.

A type of battery-operated led lights has a known mean lifetime 7.9 hours with standard deviation 0.5. Assuming that the lifetimes of these led lights have a nearly symmetric/bell-curve distribution, find the percent (%) of these led lights having lifetime between 7.9 and 8.9 hours.
Answer:
47.5% of these led lights have lifetime between 7.9 and 8.9 hours.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 7.9 hours
Standard deviation = 0.5 hours
The normal distribution is symmetric, which means that 50% of the measures are below the mean and 50% are above.
Lifetime between 7.9 and 8.9 hours:
7.9 hours is the mean.
8.9 = 7.9 + 2*0.5
So 8.9 hours is two standard deviations above the mean.
Of the 50% of the measures that are above the mean, 95% are between the mean of 7.9 and two standard deviations above the mean(8.9). So
0.5*0.95 = 0.475
47.5% of these led lights have lifetime between 7.9 and 8.9 hours.

Answer:
[tex]x = 3\sqrt 2[/tex]
Step-by-step explanation:
Given
See attachment
Required
Find x
To solve for x, we simply apply sine formula which states:
[tex]sin\ (\theta) = \frac{Opposite}{Hypotenuse}[/tex]
In this case:
[tex]\theta = 45^{\circ}[/tex]
[tex]Opposite = 3[/tex]
[tex]Hypotenuse = x[/tex]
So, the formula becomes:
[tex]sin(45) = \frac{3}{x}[/tex]
Cross Multiply
[tex]x * sin(45) = 3[/tex]
Make x the subject
[tex]x = \frac{3}{sin(45)}[/tex]
[tex]sin(45) = \frac{1}{\sqrt 2}[/tex]
So, we have:
[tex]x = \frac{3}{\frac{1}{\sqrt 2}}[/tex]
[tex]x = 3/\frac{1}{\sqrt 2}[/tex]
[tex]x = 3 * \sqrt 2[/tex]
[tex]x = 3\sqrt 2[/tex]
