Answer:
No her calculations do not make sense because the area of the smaller walls together is 234 and not 244 the total square feet of the windows and doors are also wrong. She should also subtract the doors and windows from the total so she doesn't over spend on paint. Her answer is correct just the way of finding it is wrong.
Step-by-step explanation:
Walls total sqft: (2(13ft)(9ft))+(2(16ft)(9ft))=234ft²+288ft²=522ft²
Doors+Windows total sqft: ((2(20ft)+(2(15ft))=60ft²+30ft²=90ft²
Total amount of paint needed: 522ft²-90ft²=432ft²
Amount of gallons needed remains the same
Hopefully this makes sense.
Answer:
can you show a picture of the problem?
Step-by-step explanation:
Answer:
The answer is y = -1.2
Step-by-step explanation:
You can solve this by simply adding 0.6 to both sides of the equation.
y - 0.6 = -1.8
y = -1.2
Answer:
-0.15
Step-by-step explanation:
the easiest way to do this is to convert all of the numbers to decimals. -2/5 becomes -0.4, and -1/4 becomes -0.25. Then you simplify the equation to get - 0.7 + 0.4 + 0.4 - 0.25, which you then solve to get -0.15.
B. 1 13/50
we would convert this by doing 126/100 and then simplifying to 1 26/100 and then 1 13/50
