Derek solved 1400 math problems in 70days .if derek solved the same number of math problems each say, how many math problems did derek solve each day?

the answer would be 20

Step-by-step explanation: The answer 20 is from 1400 divided by 70 making 20, if you take 1400 and turn it into 14 then 70 into 7 then divide 14 by 7 you get 2 now just add a zero to your answer.

20

Step-by-step explanation: Divide 1400 by 700 to get 20. Simple!

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
