What percent of $375 is $11.25 and what percent of $56.25 is $11.25?

Angelina_Jolie [31]

Answer:

3%percent of $375 is $11.25 and 20% of $56.25 is $11.25 .

Step-by-step explanation:

Formula

$Percentage = \frac{Part\ value\times 100}{Total\ values}$

First Part

As given

Total value = $375

Part value = $ 11.25

Put values in the formula

$Percentage = \frac{11.25\times 100}{375}$

$Percentage = \frac{1125}{375}$

Percentage = 3 %

Second Part

Total value = $56.25

Part value = $11.25

Put the values in the formula

$Percentage = \frac{11.25\times 100}{56.25}$

$Percentage = \frac{1125}{56.25}$

Percentage = 20%

Therefore 3%percent of $375 is $11.25 and 20% of $56.25 is $11.25 .

babunello [35]

2) 200 mL

3) 0.2 kg

Step-by-step explanation:

In this problem, we know that:

- With 1 liter of juice, we can fill a total of 5 cups

So we know that the total volume of 5 cups is equal to

V = 1 L

This means that the volume of each cup is equal to the total volume divided by the number of cups (5), therefore:

$V_1=\frac{V}{5}=\frac{1L}{5}=0.2 L$

And keeping in mind the equivalence between liters and milliliters:

1 L = 1000 mL

This means that the capacity of each cup is

$V_1=0.2 L \cdot 1000 mL/L = 200 mL$

Here we want to find the mass contained in each cup.

We know that the mass of a substance is related to each volume by the equation

$d=\frac{m}{V}$

where

d is the density

m is the mass

V is the volume

In this problem, we have:

V = 0.2 L is the volume of juice in each cup

$d=1kg/L$ is the density of juice (assuming it is the same as the density of water)

So, the mass of juice in one cup is:

$m=dV=(1)(0.2)=0.2 kg$

4x - 2y =7<br> X +2y =3 <br> What is x and y ??

NARA [144]

Answer:

x=2. y=1/2

Step-by-step explanation:

4x-2y=7. Equation 1

x+2y=3. Equation 2

Add the two equations

(4x+x) +(-2y+2y) =7+3

5x+0=10

5x=10 divide both sides by 5

X=2

Substitute x=2 in equation 2

2+2y=3

2y=3-2

2y=1. Divide both side by 2

Y=1/2

It took 2/3 of an hour to complete her science homework. It took Bethany 3/4 of the amount of time to do her math homework as he

SOVA2 [1]

We know there are 60 minutes in an hour. To find 2/3 of an hour we divide 60/3 to find 1/3 and multiply by 2 so:
60/3 = 20
20*2 = 40 minutes (which is 2/3 of an hour) to do science

We do the same thing with the 40 minutes. To find 1/4 of 40 minutes we divide 40 by 4 and then multiply it by 3 to get 3/4 so:

40/4 = 10
10*3 = 30 minutes

Then subtract the times 40-30 = 10 minutes

It took her 10 more minutes to complete her science homework.

Hope that helps
