In the past ten years, the population of a city decreased from 90,000 to 75,000 Find the percent decrease.

What percent of 72 is 48 with step by step process

Sedaia [141]

Answer:

67%

Step-by-step explanation:

There are a few methods to finding the percent of a number. You can use proportions:

$\frac{percent}{100}=\frac{48}{72}$

The 'percent' is the percent of the fraction that you are looking for, or 48/72.

Cross-multiply: 72x = (48)(100) or 72x = 4800

Divide both sides by 72: 72x/72 = 4800/72

Solve for 'x': x = 66.6666...

Round 66.666.... to the nearest percent: 67%

Farmer Ed has 9,500 meters of fencing,

Because it is a rectangle, the area is expressed as A = xy, or length times width.

Because it is a rectangle, the area is expressed as A = xy, or length times width.Because it is next to the river, he only needs to fence three sides, so F = x + 2y.

/2a = -7500/[2(-2)] = 1875 

/2a = -7500/[2(-2)] = 1875 x = 7500 - 2(1875) = 3750

/2a = -7500/[2(-2)] = 1875 x = 7500 - 2(1875) = 3750 

/2a = -7500/[2(-2)] = 1875 x = 7500 - 2(1875) = 3750 A = 3750(1875) = 7,031,250 m2

/2a = -7500/[2(-2)] = 1875 x = 7500 - 2(1875) = 3750 A = 3750(1875) = 7,031,250 m2
