4) Let the number be : N

Given : 10% of this number is 25

$\sf{\implies 10\% \ of \ N = 25}$

$\sf{\implies \dfrac{10}{100} \times N = 25}$

$\sf{\implies \dfrac{N}{10} = 25}$

$\sf{\implies N = 250}$

Now we need to find 60% of 250

$\sf{\implies \dfrac{60}{100} \times 250}$

$\sf{\implies 6 \times 25}$

$\sf{\implies 150}$

5) Given : James left the home at 10 : 00 AM

First : He will meet his friend Tom at the skate park which is 15 minutes walk from his home.

So, James reached the skate park 10 : 15 AM

Second : They stayed at the skate park for an hour

So, till 11 : 15 AM James and Tom were at skate park

Third : Then they will take a 10 minutes walk over to the Burger bar

So, James and Tom reached the Burger bar at 11 : 25 AM

6) First let us find 75% of 80

$\sf{\implies \dfrac{75}{100} \times 80}$

$\sf{\implies 15 \times 4}$

$\sf{\implies 60}$

Now let us find 40% of 30

$\sf{\implies \dfrac{40}{100} \times 30}$

$\sf{\implies 12}$

Now, (60 - 12) = 48

<u>Answer:</u> 75% of 80 is 48 greater than 40% of 30

7) Given : Journey to school takes 70 minutes

Find the height of a parallelogram with base 6.75m and an area of 218.72 square meters

oksian1 [2.3K]

Answer:

about 32.4 meters

Step-by-step explanation:

The area of a parallelogram is the equation A=Base times Height.

Put in the known values 6.75m and 218.72meters squared into the equation.

It becomes the total area 218.72 = 6.75(h)

To get h or height by itself, you have to divide both sides by 6.75. You will get the answer 32.402, or you can round it to 32.4 meters.

I hope this picture helps, but next time try to chose a number to cancel out the fraction. Example, y=1/3x+4 chose 3,6,9 and other multiples of 3.
