One hose can fill a goldfish pond in 36 minutes, and two hoses can fill the same pond in 20 minutes. find how long it takes the second hose alone to fill the pond.

The time taken by the second hose alone to fill the pond is 45 minutes.

Step-by-step explanation:

One hose can fill a goldfish pond in 36 minutes.

Let second hose can fill the pond alone in x minutes.

The part of goldfish pond filled by one hose in 1 minute is .

The part of goldfish pond filled by second hose in 1 minute is .

Two hoses can fill the same pond in 20 minutes.

The part of goldfish pond filled by both hose in 1 minute is .

Therefore, the time taken by the second hose alone to fill the pond is 45 minutes.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
