You take 315 and divide it by seven which would get you 45. The pizzas cost $45 each. Must be some good pizzas
You would divide 56 by 80. Which would give you 0.7. So 56 is 80% of 70
Answer:
Volume of the triangular prism = 42 square in.
Step-by-step explanation:
Volume of a triangular prism = Area of the triangular base × Height
Area of the triangular base = [Since, given triangle is a right triangle]
=
= 6 square in.
Height of the prism = 7 in
Therefore, volume of the triangular prism = 6 × 7
= 42 square inch
Step-by-step explanation:
$1.80 per pound
The amount she's supposed to buy it is
1.80 × 12.5 = $22.5
She paid $21.25 for the 12.5 pounds, that means she saved
$22.5 - $21.25 = $1.25
the amount she saved per pound is
1.25/12.5 = $0.1 per pound
Answer with explanation:
Let the length of rectangular fence = x meters
Let the width of the rectangular fence = y meters
Thus
Now Let the total cost to construct the fence be 'C' can be obtained if we construct the shorter side with material with cost $12 per foot
Using value of x from the equation i into equation ii we get
hence to minimize the cost we differentiate both sides with respect to 'y' and equate the result to zero thus we get
Thus
Thus value of length = 11.114 feet and value of width = 18.894 feet.
