Answer:
The surface area of the larger prism is 4 times the surface area of the smaller one.
(which agrees with answer B in your list)
Step-by-step explanation:
Notice that the lateral surface area of prisms always consists of parallelograms, whose areas are given by the product base times height. = B x H
Therefore if the dimensions of the prism double, then the base and height of the parallelograms will double as well, making such individual ares of the lateral faces go from:
B x H to --> 2 B x 2 H = 4 (B x H)
that is 4 times the original lateral face's area.
with the faces for the top and bottom bases of the prism, something similar happens, so we conclude that the surface area of the larger prism is 4 times the surface area of the smaller one.
Answer:
0.688
Step-by-step explanation:
There are 16 people total and 11 cookies.
This can be represented as:
,
which converted into a decimal is:
0.688
29990
10%=29990/10=2999
1%=2999/10=299.90
0.5%=299.90/2=149.95
6%=299.90x6=1799.40
6.5%=1799.50+149.95=$1949.35 tax
total +tax
29990+1949.35=$31395.35
hope this helps
Answer:
32% of the students did not have a pet.
Step-by-step explanation:
From the total students (100%):
- 1/4 of them had a dog only,
. Then, 25% had a dog only. - 20% only had a cat.
- 15% had multiple pets.
- 0.08=8% only had other than cats or dogs.
- <u>Adding up all these cases, we obtain the proportion of students that had at least one pet:</u>
. Then, 68% of the students did have a pet. - The rest of the students
, did not have any pet.
