Can yall help me pls?

Figure A maps to figure B with a scale factor of 2/3 -> Every single side of figure B equal to 2/3 of its corresponding side on triangle A.

So, we can find x by taking 10.5 x 2/3 = 7

-> x = 7

Chloe has been offered a new job in the women’s shoe department at Macy’s. She has two salary options. She can receive a salary
Umnica [9.8K]
The equations that represent the salary that Chloe's receive under the different options are:

1) Option 1: $600

2) Option 2: $ 350 + 8% * x, where x is the sales.

Using the fact that 8% = 0.08

Option 2 = $350 + 0.08x

A) If she has $3200 weekly salary:

Option 1 gives $600 (it is a constant salary)

Option 2 gives: $350 + $ 0.08 (3200) = $350 + $256 = 606.

Then, she will earn more money with the option 2.

B) The equation that can be used to determine when she earns more is found by making the two options equal:

Optio 1 = Option 2 =>

600 = 350 + 0.08x

C) Option 1 wiil lead to a greater earn when 600 > 350 + 0.08x

=> 600 - 350 > 0.08x

=> 250 > 0.08x

=> (250 / 0.08) >  x

=> 3,125 > x => x < 3,125

Then, the answer is that she will earn more money with option 1 when x < 3,125

Given the midpoint and one of the endpoints of a line segment, find the other endpoint. Midpoint: (0,3) Endpoint: (6,-3)
andrey2020 [161]

Answer:

(-6,9)

Step-by-step explanation:

Midpoint: (0,3)

Endpoint: (6,-3)

Use the midpoint formula:

M=(\frac{x_{1}+x_{2}}{2} ,\frac{y_{1}+y_{2}}{2})

Since you already have the midpoint and you need an endpoint, let the unknown endpoint be (x,y). Take the midpoint formula apart:

\frac{x_{1}+x{2}}{2}=m_{x}

\frac{y_{1}+y_{2}}{2} =m_{y}

m_{x} and m_{y} are the coordinates of the midpoint. Enter the known values of the midpoint into the equations:

(0_{m_{x}},3_{m_{y}})\\\\\frac{x_{1}+x_{2}}{2}=0 \\\\\frac{y_{1}+y{2}}{2}=3

Now enter the known endpoint values:

(6_{x_{1}},-3_{y_{1}})\\\\\frac{6+x_{2}}{2}=0\\\\\frac{-3+y_{2}}{2}=3

Solve for x. Multiply both sides by 2:

2*(\frac{6+x}{2})=2*(0)\\\\6+x=0

Subtract 6 from both sides:

6-6+x=0-6\\x=-6

Now solve for y. Multiply both sides by 2:

2*(\frac{-3+y}{2})=2*(3)\\\\ -3+y=6

Add 3 to both sides:

-3+3+y=6+3\\y=9

Now take the values of x and y and turn into a point:

x=-6\\y=9\\(-6,9)

Finito.

What is the total floor area in inches of a rectangular floor 8ft. by 6ft.?
Anestetic [448]

Answer:the answeer is

= 72 ft³

Step-by-step explanation:

Multiply the width of the wall by its height. So one of the walls is 80 square feet (10 feet wide x 8 feet high) and the other is 96 square feet (12 feet x 8 feet). If you need the total square footage of the walls - for figuring paint or wallpaper for example - you can simplify the calculation by first adding all the wall lengths together, then multiplying by the height (10 + 12 + 10 + 12 = 44 x 8 = 352 square feet of total wall area).
