Subtract 10 from both sides :
-3y + 10 - 10 = -14 -10
3y = -24
divide both sides with 3 :
y = -8
The rectangular room is 10.25 inches by 8 inches. If 1 inch represents 2 feet of the actual room. What is the scale factor and actual area of the room?
10.25 x 2 = 20.5 ft
and
8 x 2 = 16 ft
1in/ 2 ft or 1 in/ 24 inches
Answer:
huh?
Step-by-step explanation:
Answer:
44 square feet were used to build the aquarium
Step-by-step explanation:
∵ The area of the rectangular prism = Lateral area + 2 Base area
∵ The top of the aquarium is open
∴ The area of the aquarium = Lateral area + Base area
∵ Lateral area = perimeter of base × height
∵ Its base is a rectangle
∵ The dimensions of the base are 4 feet and 2 feet
∵ Its height = 3 feet
∴ Perimeter of the base = 2(4 + 2) = 12 feet
∴ Area of the base = 4 × 2 = 8 feet²
∴ Area of aquarium = 12 × 3 + 8 = 36 + 8 = 44 feet²
