Answer:
v=2πrh
r=d/2=8/2=4
Therefore, V=2×3.142×4×2= 50.272 ans.
Answer:
Tires that wear out by approximately 24307.8 miles will be replaces free of charge.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 27,000 miles
Standard Deviation, σ = 2100 miles
We are given that the distribution of life expectancy is a bell shaped distribution that is a normal distribution.
Formula:

We have to find the value of x such that the probability is 0.10
Calculation the value from standard normal z table, we have,
Tires that wear out by approximately 24307.8 miles will be replaces free of charge.
Answer:
1. 3sqrt(2)
Choice C
2. 2sqrt(3)
Choice D
Step-by-step explanation:
1. sqrt(x+3)
sqrt(15+3)
sqrt(18)
sqrt(9*2)
sqrt(9)sqrt(2)
3sqrt(2)
Choice C
2. 6/sqrt(x)
6/sqrt(3)
no radicals in the denominator, multiply by 1 in the form of the radical
6/sqrt(3) * sqrt(3)/sqrt(3)
6sqrt(3)/ (sqrt(3)*sqrt(3))
6sqrt(3)/3
2sqrt(3)
Choice D
Answer:
239 people 15$adults 5.50$ for kids
Step-by-step explanation:
Answer:
ENGLISH SYSTEM:
What you want to do is simply convert the feet into inches for 1a. and for 1b. add the inches to the length and the width. For the rest of the English system, what you have to do is plug in the numbers.
METRIC SYSTEM:
So for this one it is the same thing but different measurements. Instead of converting feet to inches, you are converting meters to centimeters. Follow the same steps as you did with the English system.
Step-by-step explanation:
1a.
13*12=156
18*12=216
1b.
156+6=162
216+9=225
2.
162*225=36,450
3.
3.75*8=30
4.
36,450/30=1,215
1a.
4*100=400
5*100=500
2.
400*500=200,000
3.
9.5*20=190
4.
200,000/190≈1,053
