Find EF in the trapezoid

Leni [432]

EF is halfway between AD and BC.

Using the midpoint formula:
$4x=\frac{(x+6)+57}{2}$
⇒ $4x=\frac{x+63}{2}$
⇒ $8x=x+63$
⇒ $7x=63$
⇒ $x=9$

EF is $4x=4(9)=36$

An excavation has a volume of 203 cubic feet. The material weighs 1,200 pounds per cubic yard. What is the weight of the exca- v

Andrew [12]

Answer: Option 'd' is correct.

Step-by-step explanation:

Since we have given that

Volume of an excavation = 203 cubic feet

Weight of the material = 1200 pounds per cubic yard

So, the weight of the excavation would be

Volume of an excavation × Weight of the material

$=203\times 1200\\\\=243,600\ pounds$

Hence, the weight of the excavation is 243,600 pounds.

Therefore, Option 'd' is correct.
