Paula goes to the store and buys a binder, a folder, and a highlighter. The highlighter's cost is half the cost of the binder, a

tatyana61 [14]

Answer:

Cost of the binder = $5

Cost of the highlighter = $2.5

Cost of the folder = $2

Step-by-step explanation:

Let

Cost of the binder = x

Cost of the highlighter = 1/2x

Cost of the folder = x - 3

Total cost = $9.50

Total cost = Cost of the binder + Cost of the highlighter + Cost of the folder

9.50 = (x) + (1/2x) + (x-3)

9.50 = x + 1/2x + x - 3

9.50 + 3 = x + 1/2x + x

12.50 = 2x + 1/2x

12.50 = 2 1/2x

12.50 = 5/2x

x = 12.50 ÷ 5/2

= 12.50 × 2/5

= 25/5

x = $5

Cost of the binder = x = $5

Cost of the highlighter = 1/2x = 1/2*6 = $2.5

Cost of the folder = x - 3

= 5 - 3 = $2

trapecia [35]

Answer: 3.7 in.

Step-by-step explanation:

Given, A toy designer is creating a basketball plushy. The designer has fabric that measures 171.9 sq. in.

To find: The maximum radius of the basketball that the designer can create.

For this, Surface area of basketball = area of fabric

Formula: Surface area of sphere = $4\pi r^2$ , where r is the radius.

Then, $4\pi r^2=171.9$

$r^2=\dfrac{171.9}{4\pi}=\dfrac{171.9}{4\times3.14}\\\\\Rightarrow\ r=13.6863057325\\\\\Rightarrow\ r=\sqrt{13.6863057325}=3.69950074098\approx3.7$

Hence, the maximum radius of the basketball that the designer can create is 3.7 in.

19x+rx=−37x+w<br><br> Solve for x

Llana [10]

19x + rx = -37x + w

Add 37x on both sides

19x + rx + 37x = w

Factor out the x

x(19 + r + 37) = w

You can simplify this to:

x(56 + r) = w

Divide (56 + r) on both sides to get x by itself

x = $\frac{w}{56 + r}$

The perimeter of a rectangular tray is 28 inches. The length of the tray is 2 inches longer the width of the tray. Determine the

fenix001 [56]

Answer:

width = 6 and length = 8

Step-by-step explanation:

perimeter = 2*(length + width). (1)

and we have that length = 2 + width

in (1)

28 = 2 *(width + 2 + width)

14= 2*width +2

width =6

and so length will be 8
