Answer:
1. ?=100 2.?=70
Step-by-step explanation:
1. for the inner arch, you just have to multiply by 2 so 50x2
2. to find the inner arch from the outer arch, you have to divide by two so 140/2
19803
Multiplying the two numbers, you get 19803.
85
Write the numbers in order
66, 72, 74, 80, 83, 87, 91, 95, 98, 99
Find the middle number
83 and 87 are in the middle, so find the mean of them. 83+87= 170
170/2 = 85.
14/63
(2*7) / (9*7) = 14/63
