2. On a blueprint for a new building, 2 inches = 8 feet. The height of the building on the

dimulka [17.4K]

<h2>Answer:</h2><h2>The actual height of the building = 36 feet.</h2>

Step-by-step explanation:

By blue print conversion,

2 inches = 8 feet

Therefore, 1 inch = $\frac{8}{2}$ = 4 feet

1 inch = 4 feet

The height of the building on the blueprint = 9 inches

The actual height of the building = 9 * 4 = 36 feet.

The Carousel at Carowinds has 4 rings of horses. Fred is riding on the inner ring, which has a radius of 7 feet. Juan is riding

nikdorinn [45]

Answer:

Juan travel 31.4 feet farther than Fred in one rotation.

Step-by-step explanation:

In this problem we need to determine the change in linear position of Fred and Juan, whose formula is:

$s=\theta \cdot r$ (Eq. 1)

Where:

$r$ - Radius, measured in feet.

$\theta$ - Angular arch, measured in radians.

$s$ - Change in linear position, measured in feet.

If both makes one rotation in the carousel, we obtain the change in linear position of each player:

Fred ( $r = 7\,ft$ , $\theta = 2\pi$ )

$s= 2\pi\cdot (7\,ft)$

$s = (3.14)\cdot (7\,ft)$

$s = 21.98\,ft$

Juan ( $r = 17\,ft$ , $\theta = 2\pi$ )

$s= 2\pi\cdot (17\,ft)$

$s = (3.14)\cdot (17\,ft)$

$s = 53.38\,ft$

And the difference between both travelled distances is:

$\Delta s = 53.38\,ft-21.98\,ft$

$\Delta s = 31.4\,ft$

Juan travel 31.4 feet farther than Fred in one rotation.

A rectangular prism has a volume of 96 ft3.the. Area of the base is 24 ft2.what is the height of the prism?

iren [92.7K]

H= 4 because volume of a prism is V=Bh and V=96 and B = 24 so it would be left as 96=24h So in order to find h we have to divide 24 by each number to find h alone so 24 divided by 24 equals 0 and 96 divided by 24 equals 4 so your answer is 4. Also, if you put the equation together after you find 4 you will see it all adds up. 96=24(4) which is correct

What is the answer, intellectuals

UkoKoshka [18]

$\huge{\boxed{227}}$

Here's our expression: $3*(5+4)^{2}-4^{2}$

We will follow the order of operations and begin by solving everything in parentheses. $3*9^{2}-4^{2}$

Next, we solve the exponents. $3*81-16$

Now, we solve the multiplication and division. There is no division, so we will just solve the multiplication. $243-16$

Finally, we solve the addition and subtraction. Since there is no addition, we will solve the subtraction. $\boxed{227}$

Answer: d

<u>Step-by-step explanation:</u>

$KE=\dfrac{1}{2}mv^2\\\\\\\bigg(\dfrac{2}{m}\bigg)KE=\bigg(\dfrac{2}{m}\bigg)\dfrac{1}{2}mv^2\\\\\\\bigg(\dfrac{2}{m}\bigg)KE=v^2\\\\\\\sqrt{\bigg(\dfrac{2}{m}\bigg)KE}=\sqrt{v^2}\\\\\\\sqrt{\bigg(\dfrac{2}{m}\bigg)KE}=v$
