Answer:

3

Step-by-step explanation:

First deal with the brackets

27^2/3 can be written as

( \sqrt[3]{27} ) ^{2 }

which simplifies to 3^2

which is 9

so now you have (9)^1/2

which is also written as

\sqrt{9}

which is 3

Step-by-step explanation:

Given

d = 24 --- diameter

See attachment for complete question

Required

Determine the area of each color

First, we calculate the area of all colors

Area = \frac{\pi d^2}{4}

This gives:

Area = \frac{22 * 24^2}{7*4}

Area = \frac{12672}{28}

Area = 452.57

Since all 4 colors have equal areas, the area of 1 of them is:

A = \frac{1}{4}Area

A = \frac{1}{4} * 452.57

A = 113.14ft^2

A = 113ft^2 --- approximated

<h3>Answer:</h3>

<u><em>The height of the rectangular prism is </em></u><u><em>2 yards in length.</em></u>

<h3>Step-by-step explanation:</h3>

By knowing that the volume of a rectangular prism is length * width * height, it is rather simple to find the answer.

Firstly, you'll multiply the lengths that you already know.

(length * width)

<em>3/4 * 1/3 ---> 0.25 or 1/4</em>

Next, you'll divide the volume by this amount to find the unknown height.

<em>1/2 ÷ 1/4 ---> 2</em>

Your height would be 2 yards in length.

Can someone help me wit this problem it is 20 points and i need to work on it for school and i Am very confused. Please help
LUCKY_DIMON [66]
So the slope of the first line is 4/3. If this line is perpendicular, then you have to flip it and switch the sign (flip it n switch it (how I remember it)). So the slope of the new line is -3/4.
Then you have to plug in the point you're given and the new slope. Use y=mx+b format.
-1=-3/4*-4+b
Then solve for b.
-3/4*-4 is 3.
-1=3+b
Subtract 3 from each side.
-4=b.
So now you have the y-intercept and slope. All you have to do is plug it in.
y=-3/4x + -4 or y=-3/4 - 4
There's your answer!
