Answer:
B
Step-by-step explanation:
The volume (V) of a rectangular prism is
V = lbh
where l is the length, b the width and h the height
We are looking for 3 values that multiply together to give 10
Considering each of the options
A
100 × × = 25 ≠ 10
B
10 × × 2 = 10
C
5 × 2 × 2 = 31.25 ≠ 10
D
10 × 10 × = 50 ≠ 10
B is the only possible dimensions for the prism
Answer:
B) -7
Step-by-step explanation:
x+y
8+(-15)=8-15=-7
Answer:
10 points
Step-by-step explanation:
since they only said 5 days and each day 2 points drop.
1 day = 2 points
5 days = 2 x 5 = 10 points
Given:
The base of a prism is a right triangle with legs measuring 16 feet and 4 feet.
Height of the prism is 14 feet.
To find:
The volume of the triangular prism.
Solution:
The area of a triangle is:
Where, b is base and h is height of the triangle.
The base of a prism is a right triangle with legs measuring 16 feet and 4 feet. It means the base of the triangle is 16 feet and height is 4 feet. So, the area of the base of the prism is:
Now, the volume of a triangular prism is:
Where, B is base area and h is the height.
Putting in the above formula, we get
Therefore, the volume of the triangular prism is 448 cubic feet.
Answer:
19
Step-by-step explanation:
The opposite sides are equal, so:
PS = 3y+1
RS = 4y+2
QR = 3y+1
PQ = 4y+2
Therefore, we can set the perimeter 90 = PS+RS+QR+PQ
90 = (3y+1) + (4y+2) + (3y+1) + (4y+2), or,
90 = 2(3y+1) + 2(4y+2)
90 = 6y+2 + 8y+4
90 = 14y + 6
84 = 14y
y = 6
Then, we go back to the question. It's asking for the length of PS. PS = 3y+1, so we plug in 6 for y
3(6)+1
18 + 1 = <u>19</u>
