When a store had Sold 2/5 of the shirts that were on display, they brought out another 30 from the stockroom. The store likes to

Inga [223]

Answer:

Part A) 3/5 is the total number of shirts remaining on display after selling 2/5

Part B) $x \geq 200$ (All real whole numbers greater than or equal to 200 shirts)

Part C) Initially on display were the amount of 200 or more shirts

Step-by-step explanation:

Let

x-------> total number of shirts on display

we know that

The inequality that represent the situation is

$(1-\frac{2}{5})x+30 \geq 150$

$(\frac{3}{5})x+30 \geq 150$

Part A) Explain what 3/5 means in the inequality

3/5 is the total number of shirts remaining on display after selling 2/5

Part B) Solve the inequality

we have

$(\frac{3}{5})x+30 \geq 150$

Subtract 30 both sides

$(\frac{3}{5})x \geq 150-30$

$(\frac{3}{5})x \geq 120$

Multiply by 5/3 both sides

$x \geq 120(5/3)$

$x \geq 200\ shirts\ on\ display$

Part C) Explain what the solution means in the situation

1) Initially on display were the amount of 200 or more shirts

2) 2/5 were sold and 120 or more shirts were left on display.

3) The store brought out another 30 shirts from the stockroom and placed them on display, for a total of 150 shirts or more on display

What is the slope of the line?

SashulF [63]

Answer:

The slope is 2

The y-intercept is 3

The equation is y = 2x +3

Step-by-step explanation:

The equation goes up 2 squares and over 1 square. 2/1 = 2

For y-intercept, look at the y-axis

The equation is supposed to be written as y = mx + b

m being the slope and b being the y-intercept.

Naomi has been contracted to put decorative lights on the outside edges of a building. She knows that each string of lights she

Lady_Fox [76]

You would divide 1350 by 47 to find our how many strings of lights she would need.

1350 / 47 = 28.7234

note that IF you choose 28, you would run short because it would not be enough to cover all of that edge.

so you would need to round up to 29

therefore our answer would be D)29 strings of lights.

Solve for lenght y. Show work<br> PLease help

dolphi86 [110]

You have a right triangle here so we are going to use a trig identity to solve for y. Y is the side opposite the angle given to us, and then we also have the hypotenuse. Opposite / hypotenuse tells us that we have to use the sin ratio to find y. $sin(52)=\frac{y}{37}$ .

In order to isolate the y, we will multiply both sides by 37 to get

37sin(52)=y. We can do this on our calculator in degree mode and will get that y = 29.156 inches
