Let h represent number of hits.
Let m represent number of misses.
1) 9h - 7m = 33
2) h - m = 2
2a) h = 2 + m
Sub 2a) into 1)
9*(2+m) - 7m = 33
18 + 9m - 7m = 33
2m = 15
m = 7.5
Sub m = 7.5 into 2a)
h = 2+ 7.5
h = 9.5
Though this does work you can’t exactly shoot a half miss or hit so h=13 and m=12 works as well...
9(13)-7(12)=33
117- 84=33
Answer:
![\frac{8}{45}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B45%7D)
Step-by-step explanation:
convert mixed number to improper fractions

Answer:
D. 2 inches.
Step-by-step explanation:
<u>Given the following data;</u>
Volume of golf (sphere) = 4 in³
A golf ball is spherical in shape. Thus, to find its volume we would use the formula for the volume of a sphere.
![Volume \; of \; a \; sphere = \frac {4}{3} \pi r^{3}](https://tex.z-dn.net/?f=%20Volume%20%5C%3B%20of%20%5C%3B%20a%20%5C%3B%20sphere%20%3D%20%5Cfrac%20%7B4%7D%7B3%7D%20%5Cpi%20r%5E%7B3%7D%20)
Substituting into the equation, we have;
![4 = \frac {4}{3} * 3.142* r^{3}](https://tex.z-dn.net/?f=%204%20%3D%20%5Cfrac%20%7B4%7D%7B3%7D%20%2A%203.142%2A%20r%5E%7B3%7D%20)
Cross-multiplying, we have;
![r^{3} = \frac {12.568}{12}](https://tex.z-dn.net/?f=%20r%5E%7B3%7D%20%3D%20%5Cfrac%20%7B12.568%7D%7B12%7D%20)
![r^{3} = 1.0473](https://tex.z-dn.net/?f=%20r%5E%7B3%7D%20%3D%201.0473%20)
Taking the cube root of both sides, we have;
Radius, r = 1.016 inches.
To find the diameter;
Diameter = radius * 2
Diameter = 1.016 * 2
<em>Diameter = 2.03 ≈ 2 inches. </em>
