Step-by-step explanation:
I just answered that. so, here again :
all we need to do is find the surface area, deduct windows and door areas.
that gives us the m² to be covered, which we have to multiply by $12.50 to get the total price.
the house surface area is like for a box, but we don't care about the top and the bottom. only about the walls.
the "box" is 18 m × 14 m × 4 m.
so, the front and the back walls are each
18m × 4 m = 72 m²
both front and back : 2×72 = 144 m²
each side wall is
14m × 4m = 56 m²
both sides : 2×56 = 112 m²
now for the deductions.
each window is
1.5 × 2 = 3 m²
both windows : 2×3 = 6 m²
the door is
1 × 2.5 = 2.5 m²
so, the total area to "side" is
144 + 112 - 6 - 2.5 = 247.5 m²
to side 247.5 m² it costs
247.5 × 12.5 = $3,093.75
Move over the # of decimal places as the negative exponent. 0.0907 is the correct answer!
Hope this helps, and please mark brainliest!
Do the crossing out method. so if it is 2.50 per pound for peaches, try A, 11 pounds. 2.50 times 11 is 27.5, and now we have the rest, 154 pounds as apples so we multiply it by 1.75 which is 269.5, we add them up and we dont get 337.50, so we try out b, 18 times 2.5 is 45 so we still have 147 pounds left for apples, multiply it by 1.75 which is 257.25 and if we add up 45 and 257.25 we dont get 337.5 so now we try c which is 65, multiply it by 2.5 its 162.5 and we have 100 pounds of apples left. we do the same and we get 175, 175 plus 162.5 is 337.5 so C/3 is the correct answer
