Answer:

A: 4

Step-by-step explanation:

So first you can move the 2^-5 to the denominator, making the equation (2^2) (4^3) / (2^5) (2)

Then simplify the terms so you end up with (4)(64) / (32) (2)

Then multiply the denominator so you end up with (4) (64) / (64)

Since both the denominator and numerator have 64, those cancel out leaving you with 4

The complete table is given below.

2. 3 miles per hour, 2.75 miles per hour, and 3.5 miles per hour are the speed of Diego, Elena, and Andre respectively.

3. To reach one mile: 0.33 hours, 0.36 hours, and 0.29 hours are the required time for Diego, Elena, and Andre respectively.

Velocity is the pace and direction of an item's movement, whereas speed is the time rate at which an object is traveling along a route.

Given:

Diego, Elena, and Andre participated in a walk-a-thon to raise money for cancer research.

They each walked at a constant rate, but their rates were different.

Answer:

15.21= 15.2 when rounded

Step-by-step explanation:

the formula for finding the area of a circle with the diameter is
A= 1/4 × π ×d^2

Answer:

15.21

Step-by-step explanation:

In order to find the area, you must find the radius first.

The diameter (4.4) divided by 2 = radius (2.2)

The area of a circle is pi times the radius squared ([tex]A = \pi r^{2}[/tex]).

In this situation, r, or radius =2.2.

[tex]A = \pi 2.2^{2}[/tex]

[tex]\pi[/tex][tex]2.2^{2}[/tex]= the area, 15.2053084434.

By rounding to the nearest hundredth, you get 15.21. The second number after the decimal is your hundredths place. If the number after the decimal is 4 or less, just remove all of the digits to the right. If it's five or more, like this case where it is 7, you add 1 to the hundredths place, then you remove all of the digits to the right.

Answer:

Prisms have two congruent — or identical — bases, and pyramids only have one base. The shape of the base on pyramids and prisms can vary, depending on the shape of the overall three-dimensional object. A prism has two identical bases that are parallel, while a pyramid has one base.

Step-by-step explanation:

We are attempting to find the circumference of the pool.

The radius is 10 feet.

We need to use the formula:

C = [tex]\pi[/tex]r²

C = (3.14)(10)(2)

C = (31.4)(2)

C = 62.8

The circumference of the pool is 62.8 feet.

Answer:

The answer is B

Step-by-step explanation:

So (x^-3)^-2= x^6 and it stays in numenator

Step-by-step explanation:

(I want the points) You split the shape into two you know how to solve.

Answer:

a. the first and last one

b. the second and third one

Step-by-step explanation:

a. 11x-3x-10x=18x, so the first one is definitely the answer. If you look at the last one, you can see that 10x+8x also equals 18x. The other options do not equal 18x, so those can be eliminated.

b. If you distribute the 3 outside of the parentheses, you can see that the expression 3(1+3y) equals 3+9y (because 3*1=3 and 3*3y=9y). So, the third one can be determined to be one of the answers. We can see that the second one also simplifies to be 3+9y, so this one can also be determined to be the answer. The other ones can be eliminated because they do not equal 3+9y.

Hope this helped! :)

Answer:

a) 18x and 8x + 10x

b) 3 × 1 + 3 × 3y and 3 + 9y

Step-by-step explanation:

11x - 3x = 8x and then 8x + 10x is left. The answers are 18x and 8x + 10x.

3 × 1 is 3 and 3y × 3 is 9y.

Answer:

The number b is bigger than the number a by 1/4 of a.

Step-by-step explanation:

If the number a is smaller than the number b by 1/5 of b, then

a + 1/5b = b.

Thus,

a= b - 1/5b= 4/5,

b= 5/4 a.

Consider the Expression b=5/4a:

b=5/4a= 4/4a+ 1/4a= a +1/4a

This gives that the number b is bigger than the number a by 1/4 of a.
