Answer:
x would be 6
Step-by-step explanation:
This is becuase since the scale factor from Fig A to B is 0.25, the length of all of the sides follows this rule.
Since x on Fig A and 1.5 on Fig B are corresponding sides, you can do:
x * 0.25 = 1.5
x * 0.25 <em>(4)</em> = 1.5 <em>(4)</em>
x * 1 =6
x = 6
Answer:
14 did not finish under 4 hours.
Step-by-step explanation:
Givens
Total number of competitors = 35
% who finish under 4 hours = 60%
Formula
Those who did not = 35 - 60%*35
Solution
Those who did finish under 4 hours = 35 * 60%
Those who did finish under 4 hours = 35*60/100 = 2100/100
Those who did finish under 4 hours = 21
Those who did not = 35 - 35*60/100
Those who did not = 35 - 21
Those who did not = 14
====================
There is another way to do this. Realize that 40% did not finish the race in under 4 hours.
Those who did not finish in under 4 hours = 35*40/100 = 1400 / 100 = 14
