819 is the sum of 437 and 382
312 people bought balcony seats and 396 people bought ground seats.
First find how they got 10 inches out of 25 centimeters.
25/10 = 2.5
This means that they divided 25 by 2.5 to get 10, and this pattern will continue throughout the whole table.
105 × 2.5 = 42
There are about 42 inches in 105 centimeters.
Another way to do this is there are 0.39 inches in 1 centimeter.
105 × 0.39 = 40.95
This rounds to 41.
This answer is probably better.
Answer:
a=9
Explanation:
The triangle is a 45-45-90 triangle, so the sides have a 1-1-root 2 ratio. So, if 9 root 2 is to root 2, then find a to 1. You can solve this by setting up the ratio and solving for a:
a/1=9root2/root2
a/1=9
a=9
