Brian purchased a rectangular-shaped granite countertop for the island in his kitchen. The granite slab measures 72 inches by 42 inches by 1.25 inches. If the density of granite is 170 pounds per cubic foot, how much does the

countertop weigh in pounds?

HELP ME PLEASE!!!

Step-by-step explanation:

Given

Dimensions of rectangular granite countertop is

Density of granite is

Volume of granite countertop

We know, 1 ft=12 inch

Weight of granite

clock

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
