6 0

Given

The area of the circle is 1200 square inches.

To find the radius of the circle.

Explanation:

It is given that,

The area of the circle is 1200 square inches.

That implies,

\begin{gathered} Area\text{ }of\text{ }the\text{ }circle=\pi r^2 \\ \pi r^2=1200 \\ r^2=\frac{1200}{\pi} \\ r^2=381.972 \\ r=\sqrt{381.972} \\ r=19.5 \\ r=20inches \end{gathered}

Hence, the radius of the circle is 20 inches.

How do I write the sum of two numbers as the product of their GCF and another sum
Delicious77 [7]
Let's assume we were given 2 numbers: 15 and 30. Their sum is:
15+30 = 45
We want to express it as the product of GCF and another sum.
15 is divisible by: 1, 3, 5, 15
30 is divisible by: 1, 2, 3, 5, 6, 10, 15, 30
The greatest number that appears in 2 series is 15.
\frac{15}{15} = 1
\frac{30}{15} = 2
In this case sum of two numbers can always be written as:
15+30 = (15\cdot 1) + (15\cdot 2) = 15\cdot (1+2) = 15\cdot 3 = 45

What is 6 more than 7 times a number is 41
son4ous [18]


the problem would be set up as 6+(7*x)=41

first u take off the number 6 by subtracting it from itself to cancel it out then u do the same to the number 41

7x =41 now u need to cancel out the number 7 attatched to the x so u divikde it by itself and then do the same to the other side so 41 divided by 7 =5.9

 so x =5.9

Braceleftzf y = 8/7 x − 2/3 <br> 8/3 x + y = 5/9
givi [52]

Answer:

  (x, y) = (77/240, -3/10)

Step-by-step explanation:

It is convenient to write the equations in standard form.

Multiplying the first equation by 21 gives ...

  21y = 24x -14

Multiplying the second equation by 8 gives ...

  24x +9y = 5

Then the system of equations in standard form is ...

  • 24x -21y = 14
  • 24x +9y = 5

Subtracting the first from the second, we get ...

  (24x +9y) -(24x -21y) = (5) -(14)

  30y = -9

  y = -9/30 = -3/10

Substituting this into the second equation, we have ...

  24x +9(-3/10) = 5

  24x = 7.7 . . . . . . . add 27/10

  x = 7.7/24 = 77/240

The solution is (x, y) = (77/240, -3/10).
