Hi, thank you for posting your question here at Brainly.
Assuming that Luis maintains the same rate of blowing each balloon, then we could determine how long it took him to blow up a single balloon
25 minutes / 10 balloons = 2.5 minutes per balloon.
If we want to know what percent of a number A is of another
number B, then all we have to do is to simply divide number A by number B. Then
either we move the decimal place of the answer two places to the right or
multiply the answer with 100, either method results in the same number.
So the percent of tested people who had an allergic reaction
to the new lotion is:
percent people = (15 / 200) * 100
percent people = 0.075 * 100
percent people = 7.5%
Therefore 7.5% of the people had allergic reaction.
Answer:
x=16
Step-by-step explanation:
hope this might of helped :/
Because it is easily divisible by 2, 3, 4, 6, 8, 12 and itself
