Answer: She ate 5/12 of the turkey.

Step-by-step explanation:

First, find a common denominator by multiplying each fraction by the denominator of the other. By doing this, you should get 8/12, and 3/12.

Next, subtract them!

ex: 2/3= 8/12

1/4=3/12

8/12-3/12=5/12

You and your friend are painting the walls in your apartment. You estimate that there is 1000 square feet of space to be painted

leva [86]

After 45 minutes you will have painted 4*45=180 square feet.

so the total number of painted area, y, is:

y=180+x*(3+4) after the 45 minutes

where x is the number of minutes AFTER THE 45 minutes:

if y is 1000 then

1000=180+x*7
820=x*7
x=117.14

so 117 minutes, or one hour and 57 minutes.

Will Mark The Brainliest. Write an equation of the line graphed in slope-intercept form using the variables x and y.

baherus [9]

Answer:

$\boxed{y=-2x+5}$

Step-by-step explanation:

The equation in slope-intercept form is given by:

$y=mx+c$

where $m$ is the slope and $c$ is the y-intercept.

The given line passes through so many points. We can use any two these points to find the slope of the line.

The line passes through $(x_1,y_1)= (1,3)$ and $(x_2,y_2)=(2,1)$ .

The slope is given by;

$m=\frac{y_2-y_1}{x_2-x_1}$ .

$\Rightarrow m=\frac{1-3}{2-1}$ .

$\Rightarrow m=\frac{-2}{1}=-2$ .

The y-intercept from the graph is $c=5$

Our equation finally becomes;

$y=-2x+5$

When a farmer is standing 80 feet from a silo, he must look up

Alisiya [41]

Answer:

102.40 ft

Step-by-step explanation:

This system can be described as a right triangle with the horizontal distance from the silo (80 ft) being the side adjacent to the 52-degree angle, and the height of the silo (h) being the side opposite to the angle. Therefore, the height can be found by:

$tan(52) = \frac{h}{80}\\ h=102.40\ ft$

The silo is 102.40 feet tall.
