Answer:
10 ft, 14 ft
Step-by-step explanation:
Let b represent the length of the shorter base. Then the longer one is b+4 and the area is ...
A = (1/2)(b1 +b2)h
120 = (1/2)(b +(b+4))(10) . . . . use given values
12 = b+2 . . . . . . divide by 10, simplify
10 = b
14 = b+4
The measurements of the two bases are 10 ft and 14 ft.
Answer:
42

because perimeter means add, so add all the number up to get the answer 42
Answer:
d. It would become narrower
Step-by-step explanation:
The width of a normal confidence interval is given by:
In which z is the critical value according to the confidence level, is the standard deviation of the population and n is the size of the sample.
W and n are inverse proportional, that is, as n(the sample size) increases, W(the width of the interval) decreases, that is, the interval becomes narrower..
So the correct answer is:
d. It would become narrower

Answer:
ok good Step 1
Write your problem.
537.95 x 9.5% = ?
Step 2
Convert the % to a decimal:
9.5% to 0.095
Step 3
Rewrite the problem with decimal replacing the percentage.
Now the problem looks like this:
537.95 x 0.095 = 51.11
This problem gives the amount of the tax.
Step 4
Add the original price with the tax amount:
537.95 + 51.11 = $589.06 (total cost)
Step-by-step explanation:
