The answer is A. If there are 30 people and 14 are boys, that means there are 16 girls. So you put 16/14 and simplify so that would be 8/7.

Answer:

±16

The principle value is 16

Step-by-step explanation:

sqrt(8) * sqrt(32)

We know that sqrt(a) sqrt(b) = sqrt(ab)

sqrt(8*32)

sqrt(256)

sqrt(16*16)

±16

A reporter determines a baseball player’s batting average, which is a ratio of the number of hits to number of times at bat. The

Tpy6a [65]

Answer:

21/99 or 7/33

Step-by-step explanation:

x = 0.212121

Then we multiple the decimal and x by hundred.

100x = 21.212121

Then we subtract the 21.212121 by 0.212121.

100x = 21.212121 - 0.212121

But when you are subtracting 100x, you need to subtract 100x by x because in the first step it said x = 0.212121.

100x - x = 21.212121 - 0.212121

You will have at the end is

99x = 21

Divide 99 on both side and you left with

21/99 or 7/33 simplified version

A clients rash measures 5cm x 4cm how much does this measure in inches

yan [13]

Given:

A clients rash measures 5 cm × 4 cm.

To find:

The measure in inches.

Solution:

We know that,

2.54 cm = 1 inch

1 cm $=\dfrac{1}{2.54}$ inch

1 cm $\approx 0.3937$ inch

Using this conversion, we get

5 cm $=5\times 0.3937$ inches

5 cm $=1.9685$ inches

4 cm $=4\times 0.3937$ inches

4 cm $=1.5748$ inches

Therefore, the measure in inches is 1.9685 inches × 1.5748 inches.

Find the volume of this composite solid.

Zina [86]

For this case we have that the figure shown is composed of a cylinder and a cone.

We have that the volume of a cylinder is given by:

$V = \pi * r ^ 2 * h$

Where:

A: It's the radio

h: It's the height

Substituting the values:

$V = \pi * (5) ^ 2 * 10\\V = \pi * 25 * 10\\V = 250 \pi \ m ^ 3$

On the other hand, the volume of a cone is given by:

$V = \frac {\pi * r ^ 2 * h} {3}$

Where:

A: It's the radio

h: It's the height

Substituting the values:

$V = \frac {\pi * (5) ^ 2 * 4} {3}\\V = \frac {\pi * 25 * 4} {3}\\V = \frac {100 \pi} {3} \ m ^ 3$

Then, the total volume is:

$V_ {t} = 250 \pi \ m ^ 3 + \frac {100 \pi} {3} \ m ^ 3$

Taking $\pi = 3.14$ , we have to:

$V_ {t} = 889.67 \ m ^ 3$

Option D
