Answer:
well the answer is... and then you... which leads to.....
Step-by-step explanation:
The raw increase from 50 to 90 is 40.
So the question is how much of 50 is 40?
Let's divide the two: 40/50 = .8
So 40 is .8 of 50. But what is .8 in percentage form?
.8 x 100 = 80%
So the move from 50 to 90 is an 80% increase.
Answer:
78"
Step-by-step explanation:
Since the body is 1.5 times bigger than the head, and Brianna wants to make the base another 1.5 times larger you would then add 1.5 + 1.5 to get 3. Then just multiply 3 x 26" to get the circumference of the base
The best way to solve this is to set up a proportion
84 21
---- = ------
x 100
then you cross multiply and divide
100 × 84 = 8400 ÷ 21 = 400
84 is 21% of 400
