82.25 square feet
Start off by multiplying 10.5 by 23.5, to get the area of her wall - 246.75 square feet. This took up 3 quartz of paint, so divide both 246.75 by 3 to find out how many square feet were painted with only 1 quartz, 82.25 square feet! :D Hope I helped!
Answer:
x=32
Step-by-step explanation:
I believe the angles are supplementary so you could use the equation:
2x+8 + 3x+22 = 180
5x+30=180
5x=160
x=32
0.674 means that it 674/1000
which mean that if the model consist of 1000 squares, you have to shade 674 of the squares.
If the model consist of 500 squares, you have to shade 337 of the squares ( you get the number after dividing both 674 and 1000 with 2)
its just 0...
Thats all its -1+1 so it would equal zero
Think about it like this
-1+1 = 1+(-1)
and when you add a negative what are you doing? Subtracting!
so 1-1 equals...?
0
he then turns around and grabs that money and sticks it for another 9 years,
add both amounts, and that's how much is for the whole 21 years.
