A pillow that usually costs $18 is marked down 25%. Use the table to find the pillow’s new price.

snow_tiger [21]

It would be 13.50 because 50% off of 18$ is 9$ but it’s not 50% off itS 25% off so If you take the 50% Off price of 9$ and add 4.50 (One more 1/4th) you get $13.50

The graph of a line passes through the points (0, -2) and (6.0). What is

9966 [12]

Answer:

$y=\frac{1}{3}x-2$

Step-by-step explanation:

The equation of a line is given in the form $y=mx+b$

Where

m is the slope with formula $m=\frac{y_2-y_1}{x_2-x_1}$

and

b is the y-intercept [y axis cutting point of line]

Given the two points (0, -2) and (6,0),

x_1 = 0

y_1 = -2

x_2 = 6

y_2 = 0

Now, we find m using formula:

$m=\frac{0+2}{6-0}=\frac{1}{3}$

Now we have

$y=\frac{1}{3}x+b$

Finding b, we plug in any (x,y) point. Lets put (6,0) and find b:

$y=\frac{1}{3}x+b\\0=\frac{1}{3}(6)+b\\0=2+b\\b=-2$

Thus,

equation of line = $y=\frac{1}{3}x-2$

Twenty-seven of the 90 acres were planted with alfalfa. What percent of the acres was not planted with alfalfa?

9966 [12]

Answer:

70 percent

Step-by-step explanation:

Find how many acres were not planted with alfalfa by subtracting 27 from 90:

90 - 27

= 63

Find what percent this is by dividing it by 90:

63/90

= 0.7

So, 70 percent of the acres weren't planted with alfalfa.
