It’s a ratio and for it to equal 2 x will equal 4
Answer:
Step-by-step explanation:
breadth = x
length = 2x
Perimeter = 540m
2*( length + breadth ) = 540
2 *(2x + x) = 540
3x = 540/2
3x = 270
x = 270/3
x = 90 m
Breadth = 90m = 90 *100 = 9000 cm
Length = 2*90 = 180 m = 180 * 100 = 18000 cm
No.of bricks = Area of room/ area of one brick
= 9000 * 18000 / 20 * 12
= 675000 bricks
Answer:
6 hours and 45 minutes
Step-by-step explanation:
162÷24=6.75
6.75=6 hours and 45 min
Answer:
Step-by-step explanation:
w = -3 and 21/25
Compound interest formula = total = P(1+r/n)^nt
Where P = is the intial amount invested
r is the interest rate, n is the number of compounding periods per year and t is the number of years.
Total = 15000(1+0.065/1)^7
Total = 15000(1.065)^7
Total = $23,309.80
