8 because 7 is closer to 5 so you round up
Answer: 
Step-by-step explanation:
You need to use the following formula to calculate the volume of Triangular prism:
Where "a" is the area of one triangular base and "h" is the height of the triangular prism.
Calculate "a" with this formula:
Where "b" is the base of the triangle and "H" is the height.
In this case:
Then, substituting values, you get that the area is the following:
Finally, you must substitute values into the formula for calculate the volume of the triangular prism, and you also must substitute 
, which is its height:
Answer:
15 square units thank you
Answer:
C. 25 ÷ 10
Step-by-step explanation:
A. 10/25
B. 2/5
C. 25 ÷ 10
D. 0.4
Total customers at Becky's restaurant = 25
Customers who order wheat rolls = 10
It means 10 out of 25 customers order wheat rolls
That is
10 / 25
Dividing both numerator and denominator by 5
= 2 / 5
2/5 in decimal
= 0.4
The option Which does NOT represent the part of the customers who order wheat rolls
is 25/10
Option C. 25 ÷ 10
Answer:28inches & 84inches
First, lets write an equation that fits the data given. The string is 112 inches long. When the two pieces are cut, the first piece will be three times as long as the second piece. If we use the variable, x, to represent the second piece, we can create the following equation...
112=3x+x
Now lets solve for x.
112=4x
divide both sides by 4
28 inches=x
Now we know that the second piece is 28inches long. Since the first piece is three times as long, simply multiply 28*3 and we'll know the length of the first piece.
28*3=84 inches
28+84=112
