Surface area is the area of the surfaces
the areas are
base
2 triangles (faces)
2 rectangluar sides

solve
area of base=legnth times width=16 times 9=144

area of 2 triangles is 2 times 1/2 times base times height=2 times 1/2 times 16 times 6=1 times 16 times 6=96

area of 2 rectangles=2 times legnth times width=2 times 10 times 9=180

total area=base+2 triangles+2 rectangles
total area=144+96+180=420 square inches

the answer is 420 square inches or B

Answer:

angle TRV=130

Step-by-step explanation:

(2x+10)+(x-10)=180

2x+10+x-10=180

2x+x(10-10)=180

3x=180

x=60

angle TRV=2x+10

angle TRV=2(60)+10

angle TRV=120+10

angle TRV=130

Papessa [141]

Answer:

48 times

Step-by-step explanation:

From the above question, we know that:

2 times = 1 kg of fertilizer

A crop requires 24 kg of fertilizer

Hence:

1 kg of fertilizer = 2 times

24 kg of fertilizer = x

Cross Multiply

x = 24 kg × 2 times/1 kg

x = 48 times

She need to fill the flask 48 times to make the required amount of fertilizer for the crop
