Answer:

C. 72\pi

Step-by-step explanation:

The radius of the circle is 24 units, then the area of the whole circle is

\pi r^2=\pi \cdot 24^2=576\pi \ un^2.

The shaded circle is limited by 45° angle, so its area is

\dfrac{45}{360}=\dfrac{1}{8}

of the area of the whole circle.

The area of the shaded circle is

\dfrac{1}{8}\cdot 576\pi =72\pi \ un^2.

In the storage room of a certain bakery, the ratio of sugar to flour is 5 to 8, and the ratio of flour to baking soda is 10 to 1
olasank [31]

Answer:

1,500

Step-by-step explanation:

Ratio of Sugar to Flour: 5:8 -> 25:40

Ratio of Flour to Baking Soda: 10:1 -> 40:4

Sugar to Flour to Soda: 25x:40x:4x

\frac{40x}{(4x+60)} = \frac{8}{1} -> x = 60

Sugar = 25x = 1,500

Hope this helps :)

A die is rolled nine times and the number of times that two shows on the upper face is counted. If this experiment is repeated m
vivado [14]

Answer:

E(x) = 1.5\\

Step-by-step explanation:

Given

n = 9 -- number of rolls

Required

The mean of 2's

The distribution follows binomial distribution where:

X \to Binomial(n,p)

In this case:

p= \frac{1}{6} ---- the theoretical probability of rolling 2

So, the mean of 2's is calculated using:

E(x) = np

E(x) = 9 * \frac{1}{6}

E(x) = \frac{9}{6}

Simplify

E(x) = \frac{3}{2} or

E(x) = 1.5\\

write the standard form of the line that passes through the given point. include your work in your final answer. (6,1)and (5,4)
bezimeni [28]
We are given two points on a line. First we need to find the slope of the line using these two points.

The given points are (6, 1) and (5, 4). The slope (m) of the line will be:

m= \frac{4-1}{5-6} =-3

Using the slope and the point (6,1) we can write the equation in point slope form as:

y - 1 = -3(x -6)

y = -3x + 18 + 1

y = -3x + 19

In standard form, the equation will be:

3x + y = 19
