brady buys 3 gallons of fertilizer for his lawn. after he finishes spraying down the lawn he has 1 quart of fertilizer left over

oksian1 [2.3K]

He used 11 quarts out or 3 gallons .
I know because in 1 <span>gallon</span> there are 4 quarts .
You do 4*3 =12.
Than you -1 from 12 and get 11.

So,Your answer is He used 11 quarts out of 3 gallons.

Hope that helped.

The circumference of Circle K is pi. The circumference of Circle L is 4xpi.

dmitriy555 [2]

Answer:

Ratio of circumferences: $\displaystyle\frac{1}{4}$

Ratio of radii: $\displaystyle\frac{1}{4}$

Ratio of areas: $\displaystyle\frac{1}{16}$

Step-by-step explanation:

Hi there!

We are given:

- The circumference of Circle K is $\pi$

- The circumference of Circle L is $4\pi$

Therefore, the ratio of their circumferences would be:

$\displaystyle\frac{\pi}{4\pi}$ ⇒ $\displaystyle\frac{1}{4}$ when simplified

The formula for circumference is $C=2\pi r$ , where <em>r</em> is the radius. To find the ratio of the circles' radii, we must identify their radii through their given circumferences.

If the circumference of Circle K is $\pi$ , or $1\pi$ , then its radius is $\displaystyle\frac{1}{2}$ .

If the circumference of Circle L is $4\pi$ , then its radius is $\displaystyle\frac{4}{2}$ , which is 2.

Therefore the ratio their radii would be:

$\displaystyle\frac{\frac{1}{2}}{{2}}$ ⇒ $\displaystyle\frac{1}{2}*\frac{1}{2}$ ⇒ $\displaystyle\frac{1}{4}$ when simplified

The formula for area is:

$A=\pi r^2$

First, let's find the area of Circle K:

$A=\pi (\displaystyle\frac{1}{2})^2\\\\A=\displaystyle\frac{1}{4}\pi$

Now, let's find the area of Circle L:

$A=\pi (2)^2\\A = 4\pi$

Therefore, the ratio of their areas would be:

$\displaystyle\frac{\frac{1}{4}\pi}{4\pi}$ ⇒ $\displaystyle\frac{\frac{1}{4}}{4}$ ⇒ $\displaystyle\frac{1}{4} * \frac{1}{4}$ ⇒ $\displaystyle\frac{1}{16}$ when simplified

I hope this helps!

the length of a rectangle is 3 ft more than twice the width, and the area of the rectangle is 77ft. Find the dimensions of the r

gladu [14]

Let x = width
2x + 3 = length

Area of rectangle is length times width

x(2x + 3) = 77
2x² + 3x = 77
2x² + 3x - 77 = 0
2x² + 14x - 11x - 77 = 0
2x(x + 7) - 11(x + 7) = 0

(2x - 11)(x + 7) = 0

x = 11/2, - 7

Distance/measurements can't be negative so x = 11/2

The length:
2(11/2) + 3
11 + 3
14

Your width is 11/2 feet and your length is 14 feet.

Create the equation of a line that perpendicular to 2y=14+2/3x and passes through the point (-2,8).

riadik2000 [5.3K]

Answer:

y = - 3x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 2y = 14 + $\frac{2}{3}$ x into this form
