Answer=8
Step-by-step explanation:
Three less than the quotient of 10 and a number increased by 6
Quotient of ten and a number=10/n
(10/n-3)+6
Let n=2
(10/2-3)+6
(5-3)+6
=2+6
=8
The answer is 8
The perimeter of the pentagon is 4,605 feet in length.
Answer:
See below.
Step-by-step explanation:
First, use the co-function identity:
We can turn the second term into cosine:
Substitute:
Now, use the sum to product formulas. We will use the following:
Substitute:
Use the even-odd identity:
Therefore:
Replace the second term with the original term:
Proof complete.
A; b; c; d = first; second; third; fourth shelfa + b + c + d = 250 cmb = 2a + 18c = a - 12d = a + 4in terms of a, plug all equations into originala + (2a + 18) + (a - 12) + (a +4) = 2505a + 10 = 2505a = 240a = 48b = 2(48) + 18b = 96 + 18b = 114 cm/1.14 m
