Answer:

a. Sale Price $=\$168.75$

b. Total percent discount $=32.5\%$

Step-by-step explanation:

First Discount:

Initial Price $=\$250$

Discount $=25\%$

$25\%\ of\ 250=\frac{25}{100}\times 250=62.5\\\\Now\ Price=250-62.5=$187.5$

Second Discount:

$Price=187.5\\\\Discount=10\%\\\\10\%\ of\ 187.5=\frac{10}{100}\times 187.5=18.75\\\\Now\ Sale\ Price=187.5-18.75=\$168.75$

Effective Discount:

Initial Price $=\$250$

Final Price $=\$168.75$

Total discount $=250-168.75=81.25$

$\%\ discount=\frac{81.25}{250}\times 100=32.5\%$

Help please I need to find the area I don’t know how thanks

otez555 [7]

Answer:

49.62

Step-by-step explanation:

You can start by dividing the shape into 2 separate rectangles to make calculating the area easier.

9.3 x 2.4 = 22.32

10.5 x 2.6 = 27.3

Then, add the areas of the two separate rectangles to find the total area of the shape.

22.32 + 27.3 = 49.62. Hope that helped

Graph these equations: x+2y=6, y=-1/2x+4 How many solutions does the system of equations have?

inysia [295]

Answer:

The system has no solution

Step-by-step explanation:

we have

$x+2y=6$

Isolate the variable y

$2y=-x+6$

Divide by 2 both sides

$y=-\frac{x}{2}+3$ ---> equation A

$y=-\frac{x}{2}+4$ ---> equation B

Compare the equations

Equation A and equation B have the same slope and different y-intercept

Remember that

If two lines have the same slope, then the lines are parallel

The solution of the system is the intersection point both graphs

In this problem, the lines don't intersect, therefore, the system has no solution

using a graphing tool

The graph in the attached figure
