Answer:

Step-by-step explanation:

The area of the wall hanging shown in blue is the area of the square 8 by 8 minus the area of the cutout. Notice the cutout is a triangle? To find the total area, subtract the area of the triangle from the square.

The square has the sides 8 by 8 and its area is found as A = 8*8 = 64.

The triangle measures 4 inches by 4 inches. The area is found as A = 1/2*4*4 = 8.

Subtract the two areas.

64 - 8 = 56

aalyn [17]

Answer:

$31\frac{2}{3}$

Step-by-step explanation:

since its only 2/5 of 1 hour, two 2/5 equal 4/5 so we divide the 12 2/3 by 2 to find the 1/5 which is 6 1/3

$12\frac{2}{3}$ ÷2= $6\frac{1}{3}$

$12\frac{2}{3} +12\frac{2}{3}=25\frac{1}{3}$

$12\frac{1}{3} +6\frac{1}{3}=31\frac{2}{3}$

valentinak56 [21]

A manufacturing company has the following fixed monthly costs and unit variable costs:

Rent = $2,200

Utilities = $375

Variable costs for materials and assembly = $13.25/unit

Monthly labor = $750

Given is the product is sold at $24.99 per unit

Let the number of units sold be x

Adding total cost = $2200+375+750=3325$

Equation becomes:

$3325+13.25x=24.99x$

$11.74x=3325$

x= 283.21

So, rounding it to nearest whole number we get, 283 units.
