Solve for y. r/3-2/y=s/5

Mathematics
1 answer:
nordsb [41]3 years ago
8 0

Answer:

y = 2 / (r/3 - s/5)

Step-by-step explanation:

r/3 - 2/y = s/5

add 2/y to both sides

r/3 = s/5 + 2/y

Subtract s/5 from both sides

r/3 - s/5 = 2/y

multiply both sides by y

y(r/3 - s/5) = 2

Divide both sides by r/3 - s/5

y = 2 / (r/3 - s/5)

The area of a pond is exactly 34 square meters, and the average depth is 34. meters. If the density of fish is 12 fish per cubic
grigory [225]

To calculate how many fish can be found in 1/3 of the pond you must first calculate the size of this.

To make calculations we use different types of units of measurement, in this case the meter measures the distance between two points in one direction.

The square meter measures the area of ​​a surface, that is, the meters in one direction for each meter in the other.

The cubic meter measures the volume of an object, that is, the meters in one direction for each meter in each of the other two.

For this case we have a pond with an area of ​​34 square meters and a depth of 34 meters, that is 34m * 34m^{2} = 1156m^{3} <em>* </em>

<em>* must remember that the units of measure should always be operated </em>

Now, the density tells us the amount of objects or matter in a given space, in this case 12 in 1 m^{3}, then in this pond would fit 12*1156m^{3} = 13872 fish so that in 1/3 of tank would fit 13782 / 3 = 4624  fish

Answer

In 1/3 of the lake you can find 4624 fish
