Answer:

The answer to your question is 50 inches

Step-by-step explanation:

Data

Area = 200 in²

diagonal 1 = 8 in

diagonal 2 = ?

Formula

Area = (diagonal 1 x diagonal 2) / 2

Solve for diagonal 2

diagonal 2 = 2 x Area 2 / diagonal 1

-Substitution

diagonal 2 = 2 x 200 / 8

-Simplification

diagonal 2 = 400 / 8

-Result

diagonal 2 = 50 in

The circumference of a circle is 36π feet. What is the length of the radius of this circle?
kap26 [50]
<h2>Hello!</h2>

The answer is: The length of the ratio is 18 feet.

<h2>Why?</h2>

There are two ways to calculate the circumference of a circle:

C=\pi d\\C=2\pi r

Since we are looking for the length of the radius, let's work with the second formula.

From the statement we know that the circumference of the cirble is 36π, so we need to isolate the ratio:

C=2\pi r\\\\36\pi feet=2\pi r\\\\r=\frac{36\pi feet}{2\pi }=18feet

So, the length of the ratio is 18 feet.

Have a nice day!

4x - 3y = -28<br>x + 5y = 39 cant seem to be able to figure the answer for this​
Rus_ich [418]

value of x = -1 and value of y=8

Step-by-step explanation:

We need to solve the system of equations:

4x - 3y = -28\,\,\,(1)\\x + 5y = 39\,\,\,(2)

Multiply eq(2) with 4 and subtract with eq(1)

4x-3y=-28\\4x+20y=156\\-\,\,\,-\,\,\,\,\,\,\,\,\,\,\,\,\,\,-\\--------\\-23y=-184\\y=\frac{-184}{-23}\\y=8

So, value of y=8

Now, finding value of x by putting value of y in equation 2

x+5y=39\\x+5(8)=39\\x+40=39\\x=39-40\\x=-1

So, value of x = -1

value of x = -1 and value of y=8
