Answer:Percent error=29%

Step-by-step explanation:

Percent error=(Estimated value-Actual value/ Actual value) × 100

Estimated value = amount of cookies Payton thought the mix could make = 36

Actual Value= Amount of cookies made= 28

Percent error= (36- 28)/ 28 x 100

=8/28 x 100

=0.2857 x 100

=28.57 rounded to 29%

The Store's wholesale price of a t-shirt is $50. If the markup set by the store is 30%. Calculate the retail price set by the st
yan [13]

Answer:

$65.    

Step-by-step explanation:

Given:

The Store's wholesale price of a t-shirt is $50

The markup set by the store is 30%.

To find:

Calculate the retail price set by the store on the t-shirt.

Solution:

Wholesale price of a t-shirt =  $50

Markup % = 30

<em>First of all we will find the markup value with the help of markup percentage and then we will simply add the wholesale price and markup value of T-shirt</em>.

Markup value of T-shirt = 30\%\ 0f\ 50=\frac{30}{100} \times50=\frac{1500}{100} =\$15

Retail price of T-shirt = Wholesale price of a t-shirt + Markup value of T-shirt

Retail price of T-shirt = $50 + $15

Retail price of T-shirt = $65

Therefore, the retail price set by the store on the t-shirt is $65.

When graphed in the (x,y) coordinate plane, at what point do the lines x - y = 12
Alex17521 [72]

Answer:

(14, 2).

Step-by-step explanation:

x - y = 12

y = 2

Solving this system:

Plug y = 2 into the first equation:

x - 2 = 12

x = 14.

Therefore the  point of intersection is at (14, 2).

Which point on the x-axis lies on the line that passes
posledela

Answer:

(2,0)

Step-by-step explanation:

For given line AB:

y-intercept = b = -2

slope = m = y₂-y₁/x₂-x₁

= -3/2-(-4) = -3/6 = -1/2

Equation of line AB:

y = (-1/2)x - 2

Finding equation of line that is parallel to line AB and passes through the point C(2,2):

Substituting the slope from line AB into the equation of the line

y = (-1/2)x + b.

Substituting the given point (-2,2) into the x and y values 2 = (-1/2)-2 + b.

Solving for b (the y-intercept) , we get b = 1

Substitute this value for 'b' in the slope intercept form equation y = (-1/2)x + 1.

For x-intercept of the line, we let y = 0

0 = (-1/2)x + 1

x = -1(-2/1)

x = +2

So, the point on the x-axis that lies on the line that passes

through point C and is parallel to line AB is (2,0).
