Answer:
The answer to your question is: 1.78 gallons
Step-by-step explanation:
Data
1 gallon = 400 ft²
room = 8 ft x 20 ft x 7 ft
Process find the area of the 6 walls of the room
Area of the floor and ceiling
A = base x width
A = 20 x 8
A = 160 ft² x 2
A = 320 ft²
Area of the walls
Area = base x width
Area = 2(20 x 7) + 2(7 x 8)
Area = 280 + 112
Area = 392 ft²
Total area = 320 + 392 = 712 ft²
1 gallon ------------------- 400 ft²
x ------------------- 712 ft²
x = (712 x 1)/400
x = 1.78 gallons
I consider that Maria will paint both the floor and the ceiling
Answer:
3347000 cm is 33.47 km to cm
3347000/64=
401.92 is the circumference
since it is pi * d
do 3347000/401.92
8327.52786624 round to
8327 full revolutions
Answer:
x = 60
y = 200
Step-by-step explanations:
Selling price:
Price of program = $0.5
Price of music = $5
Cost of production :
Program = $0.15 per program
CD = $1.75 per CD
Total Revenue = $400
Total Profit = $265
Let
Number of CD's = x
Number of program's = y
(0.5y + 5x) = 400
0.5y = 400 - 5x
y = (400 - 5x) / 0.5
y = 800 - 10x (1(
Cost of production:
1.75x + 0.15y
Profit = Total Revenue - Total cost of production
5x + 0.5y - 1.75x + 0.15y = 265
3.25x + 0.35y = 265 (2)
Put y = 800 - 10x in (2)
3.25x + 0.35y = 265
3.25x + 0.35(800 - 10x) = 265
3.25x + 280 - 3.5x = 265
-0.25x = - 15
Divide both sides by -0.25
x = -15/ -0.25
x = 60
y = 800 - 10x
= 800 - 10(60)
= 800 - 600
= 200
y = 200
Use pemdas : so do parenthesis first 15-8, then multiply the answer by 6. OR u can use distributive property & multiply 6 by 15 & 8
The answer is 0.008. Hopefully you understand why :)
