Mathematics

Answer:

62.5% or 63%

Step-by-step explanation:

He has $8. To find the percent of money that he spent on the purchase you put the amount spent over the total amount.

In this case, he spent $5. You would put that $5 over the $8, 5/8. When you divide, you get 0.625. To get a percent, you would multiply this number by 100. You end up with 62.5, or 63 if you round up.

The difference between two number is 9 and the product of the number is 162 find the 2 number
erik [133]

Answer:

18 and 9

OR

-18 and -9

Step-by-step explanation:

Let:

first number = x

second number = y

According to given conditions:

x -  y = 9 ---------- eq1

x * y = 162 ------- eq2

From eq1:

x = 9 + y

Put it in eq2:

(9+ y)*y = 162

9y + y^2 - 162 = 0

OR

y^2 + 9y -162 = 0

By factorizing we get:

y^2 -9y + 18y - 162 = 0

Taking common:

y(y - 9) + 18(y - 9) = 0

(y - 9)(y + 18) = 0

So:

y = -18 and y = 9

ignoring negative integer

Putting values of y in eq1:

   x - 9 = 9

  x = 9 + 9

   x = 18

So the two numbers are:

18 and 9

OR

-18 and -9

i hope it will help you!

Chris used 45 meters of fencing to enclose a circular garden. What is the approximate radius of the garden,rounded to the neares
kobusy [5.1K]
The length of the fencing corresponds to the length of the perimeter of the garden:
p=45 m
We also know that the perimeter of a circle is given by:
p=2 \pi r
where r is the radius of the circle.

Putting together the two equations, we have
2 \pi r = 45
from which we can find r, the radius of the garden:
r= \frac{45}{2 \pi}= \frac{45}{2 \cdot 3.14}=7.17 m

Prove that the product of the second and third numbers out of four consecutive whole numbers is two greater than the product of
podryga [215]

Let the four consecutive numbers be x,x+1,x+2,x+3.

Now the product of second and third number=(x+1)(x+2)=x²+3x+2=k

Product of first and fourth number=x(x+3)=x²+3x=k-2

A.T.Q

product of second and third number= product of first and fourth number+2

Hence proved
