Answer:

1 hour 12 minutes or 1.2 hours

Step-by-step explanation:

You add fractions to get this.

1 room/3 hours + 1 room / 2 hours = 1 room / x

0.33333333+0.5 = 1 room / x

0.83333333 = 1 / x    Multiply both sides by x

0.83333333x  = 1      Divide by 0.8333333

x = 1/0.833333

x = 1.2 hours or

x = 1 hour and 12 minutes

If the unit selling price is $2.50 unit costs $1.00 what is the margin percentage when the unit costs increased &.025
aleksandrvk [35]

Answer:

$3.125

Step-by-step explanation:

Selling Price = $2.50

Unit Cost = $1.00

Gross margin = (Unit cost/Selling price)*100

= (1/2.5)*100

Gross margin = 40%

Unit cost increased by 0.25.

New unit cost = $1.00 1+ $0.25 = $1.25

Selling price =( Unit cost/Gross margin)*100

Selling price =[ (1.25)/40]*100

= 125/40

Selling price = $3.125

Increases the unit selling price to $3.125

Hope this will helpful.

Thank you.

Find g(x), where g(x) is the translation 2 units left and 12 units down of f(x)=10x–10.
Maksim231197 [3]
We have the following transformations:
 y = f (x + c): moves the graph c units to the left.
 y = 10 (x + 2) -10
 y = 10x + 20-10
 y = 10x + 10
 y = f (x) - c: move the graph c units down.
 g (x) = 10x + 10 - 12
 g (x) = 10x - 2
 Answer:
 
the function g (x) is given by:
 
g (x) = 10x - 2

What is the equation of the line that passes through the point (-2 0) and has a slope of 2
podryga [215]

The equation of the line will be y = 2x - 2.

<h3>What is an equation of the line?</h3>

A linear equation with a degree of one is referred to as a line equation. Two variables, x, and y are present in the equation of the line. The third parameter is the line's slope, which indicates the line's elevation.

The general form of the equation of the line is given as:-

y = mx + c

Given that the equation of the line is passing through the point ( -2,0) and the slope of the line is 2.

The equation of the line will be calculated as:-

y = mx + c

-2 = 0 + c

c = -2

y = mx + c

y = 2x - 2

Therefore, the equation of the line will be y = 2x - 2.

To know more about an equation of the line follow
