Answer: 5/(2)^9
Step-by-step explanation:
(40^7)/(2^30 x 25^3)=
(2*2*2*5)^7 / (2^30 x (5*5)^3)=
(2^7 * 2^7 * 2^7 * 5^7) / (2^30 x 5^3 * 5^3)=
(2^(7+7+7) * 5^7) / (2^30 x 5^(3+3))=
(2^21 * 5^7) / (2^30 x 5^6)=
2^(-9) * 5^1=5/(2)^9

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)
