Answer:
30"
Step-by-step explanation:
We know:
E = 3*s - 11
E = 79"
Setting them both equal:
79 = 3s - 11
add 11 to both sides
79 + 11 = 3s - 11 + 11
Simplify
90 = 3s
divide both sides by 3
90 / 3 = 3s / 3
Simplify
s = 30"
Answer:
Step-by-step explanation:
We have both a secant and a tangent to that circle. The formula is, using the numbers we were given:
and
3600 = 2304 + 48x and
1296 = 48x so
x = 27
You have to divide 5 hours by 1/3 hours because you are finding out how many 1/3's you need to get 5.
5 / 1/3
You then have to do copy, dot, flop
5 x 3/1
and multiply to get
15 nights
