Answer:
The length of the pool is 28 meters and the width of the pool is 10.5 meters.
Step-by-step explanation:
In the scale drawing of Joe, the community pool has (length : width) = 8 : 3
Let the actual length of the pool is 8x meters and the actual width is 3x meters.
Now, given that the actual pool has a perimeter of 77 meters.
So, 2(8x + 3x) = 77
⇒ 22x = 77
⇒ x = 3.5
So, the length of the pool is 8x = 8(3.5) = 28 meters and the width of the pool is 3x = 3(3.5) = 10.5 meters. (Answer)
If 2x+y=5, then y=5-2x, so she substituted correctly.
x+4x=5x, so she combined like terms correctly.
She didn't subtract 10 from both sides, she added 10 to both sides.
Check the solution:
The answer is: She made no mistake.
It will be Net A and the S. A. = 12*14 + 5*14 + 2(0.5*5*12) + 14*13 = 480
The correct option is the second one.
Answer:
Sinx= 1(maximum value)
Step-by-step explanation:
The answer if 7 years, if you multiply 2,000 by .02 it equals 40. so you divide 280 by 40 and get 7
