1st problem:
Use the Pythagorean theorem:
a^2+b^2=c^2
49+361=c^2
c^2=410
c=20.24
The answer is 20m
2nd problem:
First calculate the height using the Pythagorean theorem:
a^2+b^2=c^2
20^2+b^2=625 (i got 20 {radius} by half-ing the base edge length)
400+b^2=625
b^2=225
b=15
Next, solve for the volume:
V=a^2*h/3
V=40^2*15/3
V=1600*5
V=8000
The answer is the second choice or B.
Answer:
(3,5)
Step-by-step explanation:
Answer:
The answer is B
Step-by-step explanation:
The slope is always in front of the = sign. The 4 would go into the x axis, and the 1/3 would go in to the y axis
Solve for x
-53 + 8x = 3x + 47
8x - 3x = 47 + 53
5x = 100
x = 20
