Nicholas is covering a triangular area with mulch. the base of the area is 22 ft, and the height is 10 ft. one bag of mulch covers 8 square feet. how many bags of mulch does nicholas need?
13 bags
14 bags
28 bags
40 bags

Option

Step-by-step explanation:

Step 1

Find the area of the triangle

we know that

The area of a triangle is equal to

in this problem we have

substitute

Step 2

By proportion

Round to the nearest whole number

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .

step-by-step explanation:

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
