30 inches.
When trying to find the perimeter of a rectangle, add the lengths of all of the sides. So, 5 + 5 + 10 + 10 = 30.
Answer:
32
Step-by-step explanation:
The number to the right of the decimal is higher than 5, meaning you would round up.
Answer:
The current area of the circle is 81π in².
They want to " 'decrease' " the radius to 9 in.
First, find the current radius for the current circle.
Areas of circle = πr²,
81π = πr²
First, divide π from both sides of the equation:
(81π)/π = (πr²)/π
r² = 81
Isolate the variable, r. Root both sides of the equation:
√(r²) = √(81)
r = √( 9 * 9) = 9
The radius currently is 9 in.
The NBA is not making any changes at all, therefore the question will be void. (Note that the other answer choice is -9, however, you cannot have a negative measurement, therefore, the answer is voided).

Answer:
117
Step-by-step explanation:
85 times 1 plus 32 = 117
-13 is lower than -10, therefore the question would be -13<-10
