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

Can Someone Please Help Me With This, Thanks! :)

Answer:

405

Step-by-step explanation:

So he built 5/9 of the wall, than added the extra 180 bricks to finish the wall.

so 5/9 + 180 = 9/9

so 180 = 4/9 Because 5/9 + 4/9 = 9/9

So to figure out how many bricks are in the wall we want to know what 1/9 of bricks equals and to work this out we need to divide 180 by 4

which equals 45.

Now we know that 1/9 = 45

so now to figure out what 9/9 is just multiply 45 by 9 which equals 405

Janice is building a fence around a portion of her rectangular yard. The length of yard she will enclose is x, and the width is

Kipish [7]

We are given

length of rectangular yard is x

so, $L=x$

width of rectangular yard is

so, $W=2x^2-98x+5$

We are given

the length of the enclosed yard is 50 feet

so, we get

$L=x=50$

now, we can plug x=50 and then we can find width

$W=2(50)^2-98(50)+5$

$W=105$

now, we can find total fencing length

so, total fencing length is

$=2L+2W$

now, we can plug values

$=2\times 50+2\times 105$

$=310feet$

now, we are given

the cost of fencing is $13 per foot

so,

total cost = (cost of fencing)*(total fencing length)

we can plug values

$C=13\times 310$

$C=4030$

So, Janice will spend $4030.........Answer
