mary decreased her time in the mile walk from 30 minutes to 24 minutes. What was the percent of decrease?

Answers

Answer 1

Answer: (24/30)*100 = 80%

Therefore she decreased from 100% to 80%, which is about 20% decrease.
Thus, the answer is 20%

Another way to do this is.

$((Original value - current value))/(Original value) * 100% = percentage of change in value$

Which in this case is
$(30-24)/(30) * 100% = 20%$

the pizza slice served at O'Connor's pizza place are 1/4 of a whole pizza. There are three pizzas ready to be served. 14 children come in for lunch. Is there enough pizza for every child? please explain your thinking, LOL PLZ HELP WITH MY MATH HOMWORK? THX 12 POINTS

Answers

No there will not be enough. Think about it this way. If each slice is 1/4 of the pizza, then each pizza can only feed 4 people. If you have 3 of these pizzas, then you can feed 12 people at most. Since there are 14 kids, you won't have enough.

4 pieces/1 pizza= x pieces/3 pizzascross multiplyx= 12 piecesnot enoughhope this helps

Mikhail has a savings portfolio containing $12,000, of which $3,000 is invested in CDs. His friend, Ivan, has $2,000 invested in CDs, and this investment is proportional to Mikhail's. How much money is in Ivan's savings portfolio?

Answers

Mikhail has $3.000 of his $12.000 invested in cd's, which is 3.000/12.000 = 1/4 of his total savings portofolio. Ivan too has 1/4 of his total savings portofolio invested in cd's, which is $2.000. So Ivan's total savings portofolio is 4 x $2.000 = $8.000
