The balance in the account is $3,920.14

Compound interest

The formula for calculating the compound interest is expressed as

A = P(1 + r)^t

Given

P = $3,200.00 r = 7% = 0.07t = 3 years

Substitute

A = 3200(1+0.07)^3

A = 3,920.14

Sam will pour 3 gallons of water into a cylindrical container. After he pours all the water into the cylindrical container, it will be 90% full. If the diameter of the container is 8 inches, what is the approximate height of the container in inches?
For water, use the conversion 1 cubic foot = 7.48 gallons

a. 14.16
b. 1.29
c. 116.16
d. 15.48

Answers

Using the volume of a cylinder, it is found that the approximate height of the container in inches is given by:

d. 15.48

What is the volume of a cylinder?

The volume of a cylinder of radius r and height h is given by:

[tex]V = \pi r^2h[/tex]

In this problem, Sam pours 3 gallons of water into a cylindrical container, and it will be 90% full. Hence, the volume, in cubic feet, is:

[tex]0.9V = \frac{3}{7.48}[/tex]

[tex]V = \frac{3}{0.9(7.48)}[/tex]

[tex]V = 0.4456[/tex]

The diameter of the container is 8 inches, hence the radius is of 4 inches = 0.3333 feet, considering a feet has 12 inches.

The height, in feet, will be given by:

[tex]V = \pi r^2h[/tex]

[tex]0.4456 = (0.3333)^2\pih[/tex]

[tex]h = \frac{0.4456}{(0.3333)^2\pi}[/tex]

[tex]h = 1.2768[/tex]

Considering a feet has 12 inches, in inches, the height will be of:

1.2768 x 12 = 15.48

Hence option D is correct.

Swimming Pool On a certain hot summer's day. 203 people used the public swimming pool. The daily prices are $1.75 for children and $2.25 for adults. The receipts for admission totaled $372.75. How many children and how many adults swam at the public pool that day?​

Answers

168 children and 35 adults swam in the public pool

Simultaneous equation

Let the number of children in the pool be x

Let the number of adult in the pool be y

If  203 people used the public swimming pool, then;

x + y = 203

x = 203 - y .......... 1

Also,  if the daily prices are $1.75 for children and $2.25 for adults with the receipts for admission totaled $372.75, then;

1.75x + 2.25y = 372.75

175x + 225y = 37275

7x + 9y = 1,491

Substitute equation 1 into 2

7(203-y) + 9y = 1,491

1421- 7y + 9y = 1491

2y = 70

y = 35

Since x = 203 - y

x = 203 - 35

x = 168

Hence 168 children and 35 adults swam in the public pool

Consider the scatter plot.

Select True or False for each statement.

Statement:
The scatter plot shows no association.

As the x-values increase, the y-values decrease.

Answers

The statements regarding the scatter plot are classified as follows:

The scatter plot shows no association. -> False.As the x-values increase, the y-values decrease. -> True.

How to classify the association between variables?

There can either be a positive association between variables or a negative association between variables, as follows:

Positive association happens when both variables have the same behavior, that is, as one increases the other increases, and as one decreases the other also decreases.Negative association happens when the variables have opposite behavior, as one variable is increasing the other is decreasing, or as one variable is decreasing, the other is increasing.

For this problem, we have that as the variable x increases, the variable y decreases, hence there is a negative association in the scatter plot.

A shirt and an $18 pair of pants cost $33.What is the price of the shirt?

Answers

Answer:

15 dollars

Step-by-step explanation:

Since a shirt is an unknown cost, and the pants costs 18 dollars, they costed 33 dollars overall.

In order to find the shirt price, let's subtract the price of the jeans from the total price.

33-18=15

The shirt's price is 15 dollars.

Answer:

$15

Step-by-step explanation:

$33- total cost

-$18- pants cost

=$15 for the shirt cost

In other words 33-18=x

                            15=x

x being the cost of the shirt!

Find the average rate of change for the function f(x)= 3^x + 25
Using the intervals of x=2 to x=6.


PLEASE SHOW WORK, THANK YOU.

Answers

The average rate of change, of the function, between the intervals, x = 2 to x = 6 is: 180.

What is the Average Rate of Change of a Function?

Average rate of change = [tex]\frac{f(b) - f(a)}{b - a}[/tex].

Given the function, [tex]f(x)= 3^x + 25[/tex],

The average rate of change using the intervals of, x = 2 to x = 6 would be solved as shown below:

a = 2

b = 6

f(a) = [tex]f(2)= 3^2 + 25[/tex] = 34

f(b) = [tex]f(6)= 3^6 + 25[/tex] = 754

Average rate of change = [tex]\frac{754 - 34}{6 - 2} = \frac{720}{4}[/tex]

Average rate of change = 180

Therefore, the average rate of change, of the function, between the intervals, x = 2 to x = 6 is: 180.

Round 4,386 to the nearest hundred​

Answers

Answer:

4,400 :)

Step-by-step explanation:

Answer and Step-by-step explanation:

Anytime that you are rounding a number, there is a rule that you should follow:

"Anything 1 - 4 is closest to the number before, or the lower side. Anything 5 - 9 is closest to the higher side of whatever round you are trying to get to."

If that doesn't make sense, let me explain.

In this case, we need to look at the hundreds placement, which is the 3 in this situation. But we can't look at that, because then we would be rounding to the nearest thousand.

(Important:) So, we need to look at the number behind it, which is 8. Eight is on the higher side of 5 - 9, which means that it grants us permission to round to the next hundred.

The is: 4,400.
