Answer:
144
Step-by-step explanation:
Sum of interior angles:
180(n-2)
180(10-2)
1440
Measure of each interior angle:
1440/10=144
The top and bottom faces are 3 inches by 3 inches.
Area = 3 in. * 3 in. * 2 = 18 in.^2
The front, back, right, and left faces are 3 in. by 6 in.
Area = 3 in. * 6 in. * 4 = 72 in.^2
Total surface area = 18 in.^2 + 72 in.^2 = 90 in.^2
Answer: B. 90 square inches
Answer:
b
Step-by-step explanation:
Time taken for the total workout = 15 + 30 + 45 = 90 minutes
Time taken for lifting weight : total time = 30 : 90
= 1 : 3
If n is rational, it means that

Therefore when we do n² we can write it as

Remember that the product of two integer numbers is also an integer, therefore we can guarantee that

Then we can confirm that n² is the quotient of two integers and the denominator is not zero, therefore, n² is always rational, it cannot be an irrational number
