Answer:

The pool can hold 3,136 cubic feet of water

Step-by-step explanation:

To know how much water the pool can hold,  we need to find the volume of this swimming pool, because the volume is how much a container can hold.

The formula for volume is L*W*H (length times width times height)

Let's multiply!

28*16*7=3136

Using translation concepts, it is found that the ordered pair of the final point is given by:

D. (5,4).

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In this situation, considering that we start at point (5,4), the translations are as follows:

It ends at the starting point, hence option D is correct.

Answer: julie spent 4 more dollars than mindy

Step-by-step explanation: julie spent 36 dollars in the dress while mindy spent 32 dollars

Julie spend  [tex]\$4[/tex]  more money than Mindy on the dress.

Off/Discount is an amount that is subtracted from the regular price of an item.

The original price of dress [tex]= \$39.99[/tex]

Julie buys the dress for [tex]10\%[/tex] off at its original price.

So,

Julie buys the dress for  [tex]= 39.99-(39.99*\frac{10}{100} )[/tex]

                                         [tex]= \$35.991[/tex]

Mindy buys the same dress for [tex]20\%[/tex] off at its original price.

Mindy buys the same dress for [tex]= 39.99-(39.99*\frac{20}{100} )[/tex]

                                                    [tex]=\$31.992[/tex]

So,

Julie spend more money than Mindy on the dress [tex]=35.991-31.992[/tex]

                                                                                    [tex]=\$3.999[/tex]

                                                                                    [tex]=\$4[/tex]

Hence, we can say that Julie spend  [tex]\$4[/tex]  more money than Mindy on the dress.

Given "Two triangles that have three pairs of proportional sides are always similar."

Triangle 1: 18, 24, 36

Triangle 2: 16, 18, 24

16/18 = 8/9

18/24 = 3/4

24/36 = 2/3

So the three pairs of sides are not proportional and the triangles are not similar.

No as

One ratio is unsimilar so triangles are not similar

Answer: y = 1/4x -2.

Step-by-step explanation: The formula for these types of equations is y = mx + b, where m is the slope and b is the y-intercept.  The slope, in this case, is 1/4 and the y-intercept is -2.  The equation of the line for this problem is y = 1/4x - 2.

The function that translates every point of the function f(x) 5 units above can be represented by g(x)=log₂x + 5.

A function assigns the value of each element of one set to the other specific element of another set.

As the function that is given to us is f(x)=log₂x, therefore, the function can be written as,

[tex]y=f(x)=\rm log_2x[/tex]

Now, since we need every point to be up by 5 units, therefore, every value of x should be +5 on the y axis, therefore, the function that will represent that every point up by 5 units of the function f(x) can be written as,

[tex]g(x) = y+ 5\\\\g(x) = f(x) + 5\\\\g(x) = {\rm log}_2x + 5[/tex]

Hence, the function that translates every point of the function f(x) 5 units above can be represented by g(x)=log₂x + 5.

We see that angle 1 and angle 2 are equal.

By the vertical angle theorem, the opposite (vertical) angles of two intersecting lines are congruent, we see that angle 1 and angle 3 must be equal. Since angle 1 and angle 2 are equal, then angle 2 and angle 3 are equal.

And for angle 1, it must be 90 degrees, because if it was any other angle measure, angle 1 and angle 2 could never be equal

In three hours, it will cover 3 full circles. Then the area of the circle covered in three hours is 980.55 cm².

It is a locus of a point drawn at an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

A clock's minute hand travels one full circle each hour.

A particular clock's minute hand is 10.2 cm.

In one hour, it covers one full circle. Then in three hours, it will cover 3 full circles.

The area of the circle covered in three hours will be

[tex]\rm Area \ of \ circle \ in\ 3\ hours = 3 * area\ of\ one\ circle\\\\Area \ of \ circle \ in\ 3\ hours = 3*\pi r^2\\\\Area \ of \ circle \ in\ 3\ hours = 3*\pi*10.2*10.2\\\\Area \ of \ circle \ in\ 3\ hours = 980.55[/tex]
