Answer:
8.9 in.
Step-by-step explanation:
Area of triangle = (1/2) b. h
40 = (1/2) x*x
80 = x^2
square root (80) = x
x=> 8.944.... inch
Rounding off you get 8.9 in.
Answer:
rc length = 10 * 8pi/5
= 16pi
This is the circumference of the base
(a) 2pir = 16pi where r = radius of base
2r = 16
r = 8 cm
(b) 10^2 = h^2 + 8^2
h^2 = 100 - 64
= 36
h = 6 cm
Answer:
204,160,000
Step-by-step explanation:
Assuming the sample is a good representation of the people from the United States.
Since there were 1,000 surveyed... and 638 of them were wearing glasses, that makes a proportion of 638 out of 1,000 people, or 63,8 / 100 people... so 63.8%... or 0.638
So, if we assume that the US population is of 320 million, how many people does that make wearing glasses.... we just have to multiply 320M by 0.638
G = 320,000,000 * 0.638 = 204,160,000
