Answer:

$\frac{500\pi }{3}$ ft³

Step-by-step explanation:

The surface area of a sphere = 4πr², hence

4πr² = 100π ( divide both sides by 4π )

r² = 25 ( take the square root of both sides )

r = $\sqrt{25}$ = 5, hence

V = $\frac{4}{3}$ πr³

= $\frac{4}{3}$ π × 5³

= $\frac{4}{3}$ π × 125 = $\frac{500\pi }{3}$ ft³

Answer:

(500π)÷3

Step-by-step explanation:

area=4πr^2 , volume=4(πr^3)÷3

area=100π ,so r=5

Answer:

KL = 6

Step-by-step explanation:

IJ + JK +KL = IL

9+ 11 + KL = 26

Combine like terms

20 + KL = 26

Subtract 20 from each side

20+KL -20 =26-20

KL = 6

Pls help I don't understand this

<h3>Answer:</h3>

<u>By angle bisector property</u>,

11x + 23 = 8x + 35
11x - 8x = 35 - 23
3x = 12
x = 4°

So, <u>m∠ABD</u> = 8x + 35

8 × 4 + 35
32 + 35 = 67°

<u>m∠CBD</u> = 11x + 23

11 × 4 + 23
44 + 23 = 67°

<u>m∠ABC</u> = 67° + 67° = 134°

Answer:

The correct option is A.

Step-by-step explanation:

If a line passes through two points $(x_1,y_1)$ and $(x_2,y_2)$ , then the equation of line is

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

Let y be the profit (in millions) after x years.

From the given graph it is clear that the line passes through the point (1,-100).

The company paid for these costs and made combined profits of $80 million after 4 years. It means the graph passes through the point (4,80).

The line passes through (1,-100) and (4,80). So, the equation of line is

$y-(-100)=\frac{80-(-100)}{4-1}(x-1)$

$y+100=\frac{180}{3}(x-1)$

$y+100=60(x-1)$

$y+100=60x-60$

Subtract 100 from both sides.

$y+100-100=60x-60-100$

$y=60x-160$

The function form is

$f(x)=60x-160$

Therefore, the correct option is A.

If an airplane pilot was told to rotate his plane while he was flying to Honolulu, would that be enough information for her to k

Talja [164]

Answer:

no, this reason being is because lets say she needed to know exact angle. she would need to know which rotational way to turn (left right up down, etc.) if this informaton is given to the pilot, they may be left confused and they make the wrong turn or wrong direction.

Step-by-step explanation:

I hope this helps :)
