So first thing ya gotta do is find the area of the circular plates, which the equation is A= \pi r^2 .

To get the radius, just divide the diameter, 30, by half. So in this case the radius would be 15.

Now that ya know that 15 is the radius, you can plug it into the equation.

A= \pi 15^2

A=225 \pi (I would advise you don't round anything until the end to get more accurate answers.)

So now that you know the area of the plate, you're gonna just multiply the area by 1/3 for lasagna and 2/3 for the salad.

225 \pi ( \frac{1}{3} )=235.6

225 \pi ( \frac{2}{3} )=471.2

(also make sure to use cm^2 units!)

Find the value of x. NO LINKS AT ALL!! ​
lyudmila [28]

Answer:

x= -7

The whole thing is just an awkward mirror but the lower triangle has an angle that is 1 degree smaller so the whole lower section is going to be bigger or smaller and the angle that mirrors the 80 degree angle is now 79 degrees which makes the other angle on that line 1 degree bigger which would be 101 so you put it in the expession to make it the equation -12x+17=101 and you solve for x which you would then get -7.

The length of a rectangle is 9 inches more than half the width. Find the length if the perimeter is 60 inches.
valentina_108 [34]

Answer:

Length = 10.435 inches

Step-by-step explanation:

Let the length be l

Let the width be w

Since the length is 9 inches more than half the width.

Then;

L = 0.5w + 9

Perimeter of a rectangle is;

P = 2Lw

Thus;

P = 2w(0.5w + 9)

Since perimeter = 60

Then;

2w(0.5w + 9) = 60

w² + 18w = 60

w² + 18w - 60 = 0

From quadratic formula;

w ≈ 2.87 in

L = 0.5(2.87) + 9

L = 10.435 in

How do you solve this?? Please help!
Aleks04 [339]

f = (f1 f2) / (f1 + f2)

f(f1 + f2) =  f1 f2

f f 1 + f  f 2 = f1 f 2

f1 f2 - f f2 = f f1

f2 (f1 - f)  = f f1

f2 = (f f1) / (f1 - f) <==== solution
