you have to make a common fraction 7/8 - 1/2 you have to multiply 1/2 by 4 to make a common fraction 7/8-4/8 equals 3/8 that can not be simplified.
Answer:
h ≈ 6
Step-by-step explanation:
Using the formula:
Or: ![V = \pi r^{2} \frac{h}{3}](https://tex.z-dn.net/?f=V%20%3D%20%5Cpi%20r%5E%7B2%7D%20%5Cfrac%7Bh%7D%7B3%7D)
We can rearrange to make h the formula:
h= 3 (64/3.14×3.2²)
h = 3(64/3.14×10.24)
h=3(64/32.1536)
h=3(1.99044585987)
h= 5.97133757962
h ≈ 6
2x - y = 7
y = 2x - 7 this line has slope = 2
Perpendicular lines, slope is opposite and reciprocal so slope = -1/2
Answer
A . -1/2
Answer:
1) They are similar
2) 45 ft
Step-by-step explanation:
1) similar because both triangles have congruent interior angles
2) 75/35 = AB/21
AB = 45 ft
Yes, because 90+90 adds up to 180 which is supplementary
