Answer:
The answer is below
Step-by-step explanation:
From the image attached, the measurement of the roof is 5 m by 9 m on both sides. Hence:
Area of roof = 2 (5 * 9) = 90 m²
Since solar panels cost $4.00 per square meter, therefore:
Cost of solar panels = $4.00 per square meter * 90 m² = $360
The area of the front wall of the barn = (8 m * 7 m) + (1/2 * 8 m * 3 m) - (4 m * 4 m) = 52 m²
The area of the back wall of the barn = (8 m * 7 m) + (1/2 * 8 m * 3 m) = 68 m²
Area of each side wall of barn = 9 m * 7 m = 63 m²
Total area of wall = 52 m² + 68 m² + (2 * 63 m²) = 246 m²
Cost of shingles = $2.50 for each square meter * 246 m² = $615
Total cost of project = $615 + $360 = $975
2.35 is already rounded to the nearest hundredth.
Answer:
Step-by-step explanation:
L and W are the length and width of the garden, respectively.
perimeter = 2L+2W = 38 ft
L+W = 19
the length is 5 ft longer than the width
L = W+5
substitution
(W+5)+W = 19
2W+5 = 19
W = 7
Answer:

Step-by-step explanation:
We have that, a die is rolled once.
As, the total outcomes can be 1, 2, 3, 4, 5, 6.
So, the probability to obtain 2 is
and the probability to obtain 6 is
.
Thus, the probability of rolling 2 or 6 after rolling a die once will be
i.e.
.
Hence, the probability of rolling a 2 or 6 is
.
Answer:
x=28/3 or 9 1/3
Step-by-step explanation:
triangle ABC is equal to triangle ADE by HL. you can solve this by setting up a proportion so for the sides its CB/ED=AB/AD. then just plug in the side lengths, cross multiply and youre done
7/13=x/8+x
56+7x=13x
56=6x
56/6=x
28/3=x
