Answer:
$1800
Step-by-step explanation:
Volume of the foundation: 30*12*6 = 2160 cubic feet
we need to convert this into yards because a truckload is 8 cubic yards, 2160/3 = 720 cubic yd
One truckload is 8 cubic yards
# of truckloads needed: 720/8 = 90 truckloads
Cost: $20*90 = $1800
1) calculate the volume of the tri prism 2) find area of the base face 3) find the height 4) multiply area of the triangle base time height 5) answer will be in cubic units
Answer:
2(10+15)= (2x10)+(2x15) 20+30=50
Step-by-step explanation:
Answer:
k = 10
Step-by-step explanation:
The triangles angels added up must equal 180 degrees, and the top angle is 65 degrees by the 180 degree rule.
So 10k + 15 must equal the remaining 115
subtract 15 from each side and you get 10k = 100
divide each each by 10 and you get the answer of k = 10
The same way you solve any other math problem:
You use the information you're given, and all the formulas, equations, and rules
that you know that might connect what you're given to what you need to find, and
then choose the best one to find the missing answer from the given information.
