Answer:
210
Step-by-step explanation:
first I took 120 and divided by four to show how many cupcakes he can make in thirty minutes (.5 of an hour). this was 30. the reason we divided by four is because in two hours theres four halves.
120÷4=30 for half an hour
30x2=60 this is how many cupcakes he can make in one hour
since we already know how many he makes in two hours we're going to use that
120+60=180 (three hours)
120+60=180 (three hours)180+30 (half an hour) =210
Answer:
200,300,290,320,340
Step-by-step explanation:
If the mean of five numbers = 290
Then the total sum of the five numbers should be= 290*5
= 1450
an example of a set of five different numbers whose mean is 290
= 200,300,290,320,340
Summation of the above
=( 200+300+290+320+340)
= 1450
So the above set of numbers is a good example of a set of five different numbers whose mean is 290
