Answer:

3.38pi

Step-by-step explanation:

Using simple math and the equation for finding the volume of a sphere, we can see that by taking the height of 10, and the volume of 30, that with that information we can deduce that the radius of the cone would be 1.69pi. With this information, we know the radius is half of the diameter. Therefore, we multiply 1.69 by 2, to get our end result, 3.36pi

1/2s=4s-21 I don't understand
Dimas [21]
\frac{1}{2} s = 4s - 21

First, simplify \frac{1}{2} s to \frac{s}{2} / Your problem should look like: \frac{s}{2} = 4s - 21
Second, multiply both sides by 2. / Your problem should look like: s = 8s - 42
Third, subtract 8s from both sides. / Your problem should look like: s - 8s = -42
Fourth, simplify s - 8s to -7s. / Your problem should look like: -7s = -42
Fifth, divide both sides by -7. / Your problem should look like: s =  \frac{-42}{-7}
Sixth, simplify \frac{42}{-7} to - \frac{42}{7} / Your problem should look like: s =  \frac{42}{7}
Seventh, simplify \frac{42}{7} to 6. / Your problem should look like: s = 6

Answer: s = 6

Evaluate each expression. Name the property used in each step.
IRINA_888 [86]

1. (1 / 5)5 * 14 = 14 because 1/5 multplied by 5 is equal to 1. I believe this is called reciprocals.

2. 6 + 4 (19 - 5) = 6 + 4(19) - 4(5) = 6 + 76 - 20 = 62. This is called the distributive property.

3. 5 (14 - 5) + 6 (3 + 7) = 5(14) - 5(5) + 6(3) + 6(7) = 70 - 25 + 18 + 42 = 105. We also used the distributive property in this question.

A baseball player made six hits in nine innings. What is the ratio of hits to innings?
UNO [17]
A baseball player made six hits in nine innings.

Therefore, his ratio of hits to innings, which means his number of hits relative to the number of innings, is 6:9.

However, this isn't simplified.  To simplify a ratio, we must find the GCF (Greatest Common Factor) of the two terms.

The GCF of 6 and 9 is 3, thus, we divide both of the terms by 3 to get our simplified answer.

6:9 = 6/3 : 9/3 = 2:3

Your answer is that the ratio of hits to innings for the baseball player is 2:3.  (This can also be expressed as 2/3 or 2 to 3.)

Hope this helps! :)
