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
Answer:
36 : 4
Step-by-step explanation:
40 divided into ratio 9:1 is like 40 / (9 + 1) multiplied to both sides of 9:1
40 / (9 + 1) = 4, and if you multiply both sides by 4, you get 36 : 4
If 6 is the longest side, and 4 is the shortest side, then the middle has to be 5.
Answer:
$14025.52
Step-by-step explanation:
The Total amount after a compound interest can be calculated using the formula:
where P is the amount of deposit, R is the rate of interest, n is the duration.
Hence by substituting the values, we get:
T = <u>$14025.52 (nearest cent)</u>
Answer:
A mango costs $4.68, a coke costs $1.56 and a taco costs $4.25
Step-by-step explanation:
Given
Represent Tacos with T, Coke with C and Mango with M
For Grace:
--- (1)
For Mia:
-- (2)
Required
Determine the cost of each item
Substitute 3C for M in (1) & (2)
--- (4)
--- (5)
Divide through (5) by 5
Solve for C
Substitute 5.81 - T for C in (4)
Collect Like Terms
Solve for T
Recall that:
Recall that
Hence:
<em>A mango costs $4.68, a coke costs $1.56 and a taco costs $4.25</em>
