The answer is 184. 23 * 8 = 184. 184 * 2 = 368. 368 ÷ 2 = 184
<span>A=1/2(a+b)h for h.
First, you need to get rid of 1/2, so divide both sides by 1/2.
A/(1/2) = (a + b)h
You can simplify the </span>A/(1/2) by multiplying by the reciprocal of 1/2, so 2/1.
2A = (a + b)h
Now divide both sides by (a+b).
2A/(a+b) = h
Answer:
Step-by-step explanation:
The 22 degree angle is opposite to the 10 m side of the right triangle.
We need to find the length x of the hypotenuse.
<u>Use trigonometry:</u>
- sine = opposite/hypotenuse
- sin 22° = 10/x
- x = 10 / sin 22°
- x = 26.7 m (rounded)
Answer:
A. 0.020
Step-by-step explanation:
we calculate the standard error of the sample mean with the formula,
,
with E= standard error of the sample mean
s= standard deviation
n= sample
So,
s= 0.2
n= 100
