Beth made wristbands and belts for a craft sale. She sold 30 of these items. Each Wristband sold for $5.50. Each belt sold for $

Serhud [2]

Let W = number of wristbands.
Let B = number of belts.

Number equation: W + B = 30
Value equation: 5.50W + 8.75B = 204.00

Multiply the top equation by 5.50 and subtract it from the bottom equation:
5.50W + 8.75B = 204.00 <--- 5.50(W + B = 30)
5.50W + 5.50B = 165.00
---------------------------------
---> 3.25B = 39.00 <--- subtract down the columns
---> B = 12 <--- divide by 3.25

Since W + B = 30 ---> W + 12 = 30 ---? W = 18

There were 12 belts and 18 wristbands.

Lines m and p are perpendicular if the slope of line m is -3 what is the slope of line p

fenix001 [56]

If thei are perpendicular their slopes will be the opposite inverse of each other, so if the slope of line m is -3 the slope of line p will be $[(-3).(-1)]^{-1}$ = $3^{-1}$ = $\frac{1}{3}$

Can done one tell me the answer to the question I just imputed?

Square foot is a unit of area. find the area of the manhole. A = (pi)r^2

9.2 lbs per square foot multiplied by area in units of square feet gives lbs.

diameter is twice radius, so radius is 1.5 ft.
Area of manhole = (pi)(1.5)^2
lbs manhole = (9.2)(pi)(1.5)^2
= 65 lbs

3. Trudy wants to surround her garden on all four sides with fencing. Her rectangular garden is 270 cm by 130 cm. How many meter

vovikov84 [41]

8 meters of fencing will be required by Trudy to surround her garden on all four sides

Step-by-step explanation:

We need to find the perimeter of rectangular garden.

We are given:

Length = 270 cm

Width = 130 cm

Perimeter= ?

Using the formula:

$Perimeter = 2(Length+Width)\\Perimeter = 2(270+130)\\Perimeter = 2(400)\\Perimeter = 800 cm$

Since we need to find the fencing in meters we divide the perimeter by 100

$Perimeter = \frac{800}{100}\\Perimeter = 8 meters$

So, 8 meters of fencing will be required by Trudy to surround her garden on all four sides
