Answer:

19 birds

Step-by-step explanation:

First, I wrote my two equations:

5.5x +8.5y = 291.5

x + y = 41

Next, I got the variable y by itself in the second equation. Subtract x to get y = -x + 41. Then, I substituted what y equaled into the first equation. It should look like this: 5.5x + 8.5(-x+41) = 291.5. Distribute 8.5 to get 5.5x -8.5x + 348.5 = 291.5. Subtract 5.5x and 8.5x to get -3x. It should look like this: -3x + 348.5= 291.5. Subtract 348.5 from 291.5 to get -57. Now, you should have -3x = -57. Divide -3 from both sides, to get x = 19. So, there are 19 birds. If you want to go even further, 41-19= 22, which means there are 22 cats. Hope this helped!

Workout the area of the quarter of a circle with a radius of 8
QveST [7]

Answer:

16\pi

Step-by-step explanation:

We need to find 1/4 of the area of a circle with a radius of 8

Let r be radius

Area of a circle = r^{2} \pi

Substitute r with 8

Area of a circle = 8^2\pi =64\pi

Now, to find 1/4 of the area, we can create an equation \frac{64\pi }{4}={16\pi

The answer is 16\pi

Hope this helps :)

Have a spectacular day!

Find the amount of tax and the tax rate. Round to nearest hundredth of a percent.
zimovet [89]

since the selling price is 89.83 and the cost of is 76, the tax amount is 89.83 - 76 = 13.83.

if we take 76 to be the 100%, what is 13.83 off of it in percentage?

\begin{array}{ccll} amount&\%\\ \cline{1-2} 76 & 100\\ 13.83& x \end{array} \implies \cfrac{76}{13.83}=\cfrac{100}{x} \\\\\\ 76x=1383\implies x=\cfrac{1383}{76}\implies x\approx 18.20

A rectangle garden has a length of 12 feet. you need 36 feet of fencing to enclose the garden. what is the width of the garden ?
iren [92.7K]

Let us suppose the width is x feet

the length is given 12 feet

Perimeter of teh garden = 2( Length + width )= 2( 12+ x)

Fencing required = perimeter of garden

36 = 2( 12+x)

36 = 2*12 + 2x

36 = 24 + 2x

36-24 = 2x

12 = 2x

12/2 = x

6 = x

Width = x feet = 6 feet .Answer .
