25% of what number is 75

1 answer:

5 0

Let's form an equation. To find the percent of a number, you multiply the percent divided by 100 and the initial number. X will be the initial number.
.25x=75; let's divide.
75÷0.25= 300
The initial number is 300. We can make sure 75 is a quarter of 300 by dividing 300 by 4.
300÷4=75

So, the number is 300.

tankabanditka [31]

Answer:

She lives 1/5 miles away from the library

Step-by-step explanation:

Here, we want to get the distance that Sheila

lives from the library

From the question, we are told she lives 1/3 as far as Doreen

So what we have to do in this case is to simply multiply the distances

we have this as:

1/3 * 3/5 = 1/5

John has decided to prepare an old field for his son's new horse. the length of the field is 10 meters less than 4 times its wid

tatuchka [14]

Answer: The total money invested in the field will be $1,623.80

Step-by-step explanation:

step 1

Find the dimensions of the field

Let

x -----> the length of the field

y -----> the width of the field

p=2(x+y)

p(4.80)=1,584

p=330m

we know that

The perimeter of the field is equal to

330=2(x+y)----> equation A

x=4y-10 ------> equation B

substitute equation B in equation A and solve for y

330=2(4y-10+y)

165=(5y-10)

5y=165+10

y+35

Find the value of x

x=4(35)-10+130

therefore

The length of the field is 130 meters and the width of the field is 35 meters

step 2

Find the area of the field

The area of the field is

A=xy

substitute

A=(130)(35)=4,550m2

step 3

Find the number of bags of seed

Divide the area by 460

4,550/460=9.89 bags

Round up to the nearest whole number

9.89 bags=10 bags

step 4

Find the cost of the seed

(10 )(3.98)=$19.8

step 5

Find the total money invested in the field

1,584+$39.8=$1,623.80
