Answer:
92
Step-by-step explanation:
83*4 = 332
And 80*3 = 240
332-240 = 92
So you would need 92
Answer:
C. 28 ft³
Step-by-step explanation:
The general formula for the volume of a pyramid:
V =
, where B = the area of the base and h = height of the pyramid
Since the base is a rectangle, we can find area using the formula:
A = l x w or A = 3 x 4 = 12 ft²
Using B = 12 and h = 7:
V = 
V = 28 ft³
The second choice is correct. Given that angle 2 and angle 6 are congruent, the largest in each of the corresponding triangles are vertical angles meaning that two known angles are known in each triangle (and they are equal) which means that the last "unknown" (angles 3 and 7) are congruent. The lines DC and AB correspond with these defined, congruent triangles meaning they are parallel.
