Answer:
The answer is 75 miles per hour
Step-by-step explanation:
225÷3=75 ( how many times 3 go into 225)
We can check to see if this answer is correct by multiplying 75 by 3 ( multiply 75 three times)
75×3=225
There for 75 is the correct answer
(I hope this helped you answer your question. If you want to check if I'm correct you can use a calculator! Have a wonderful day!)

Answer:
64.5°
Step-by-step explanation:
angle of elevation is the angle from the point where the shadow ends. this create a right angle triangle. using tan, you can find the angle.
tan theta = opposite/adjacent
angle = tan^-1(42/20)
angle = 64.5°
We are given the expression:
(17.6^-1)^8 = 17.6 ^ -8
This means that the two terms on each side are equal. We are asked to show how this is possible.
First, use the rule of exponents. If a term raised to the power of a number x^n and is further raised to the power m: (x^n)^m, to simplify the expression, multiply n and m and this will be your end exponent = x^nm.
We can apply this rule here:
17.6^-1 ^ 8
-1 * 8 = -8
then, retain the base and replace the exponent with the product nm:
17.6 ^-8. This proves that the left term is equal to the right term. <span />
