B would be the answer I think
Answer:
Surface area: 250
Volume: 1375
Step-by-step explanation:
Scale factor: 4:5
This means that the dimensions of the larger figure are 5/4 of those in the smaller figure.
Surface area:
The surface area is found multiplying the square of the change(5/4) by the original surface area(160). So
Volume:
The volume is found multiplying the cube of the change(5/4) by the original volume(704). So
Answer: 16
Step-by-step explanation:
First, you need to do 12+16, which gives you 28. Next, you need to do 92-28, which gives you 64, then divide that by 4 and you get 16.
It will be .422222222 because if you divide the to fraction first then you will get the different numbers and then you will divide them to getter and there you have your answer.422222222
it is the same denominator therefore only the numerators are added and the sign is maintained. The answer is -12/9 but it can be reduced to -4/3.
