Find the area of the following figure.
Rus_ich [418]

Answer:

A. 312 cm²

Step-by-step explanation:

The figure compromises of a rectangle and 2 equal triangles.

Area of the figure = area of the rectangle + area of the two triangles

Area = L*W + 2(½*b*h)

Where,

L = 16 cm

W = 12 cm

b = 12 cm

h = 10 cm

Plug in the values

Area = 16*12 + 2(½*12*10)

= 192 + 120

= 312 cm²

Evaluate the expression: –(31 + 2) + 72 – (–5)2.
Rudiy27

Answer:

 14

Step-by-step explanation:

Order of operations rules require that we do any work inside parentheses first.  Thus,

–(31 + 2) + 72 – (–5)^2

becomes:

     -33    + 72 -  25, or

               14

Important:  Please use " ^ " to denote exponentiation; (-5)2 is incorrect, whereas (-5)^2 or (-5)² is correct.

elena55 [62]

Answer:

Martha earns $65.6 over the weekend.

Step-by-step explanation:

Brownies sold by Martha on Saturday = 60

Cookies  sold by Martha on Saturday = 42

Brownies sold by Martha on Sunday = 28

Cookies  sold by Martha on Sunday = 54

Total brownies sold by Martha over the weekend = 60+28=88

Total cookies sold by Martha over the weekend = 42+54=96

Cost of a brownie = $0.20

Cost of a cookie = $0.50

Total cost of brownies sold over the weekend = 88\times \$0.20 = \$17.6

Total cost of cookies sold over the weekend = 96\times \$0.50 = \$48

∴ Total money Martha earned over the weekend = \$17.6+\$48=\$65.6 (Answer)
