Ooh a challenge!
so first find the surface area which is
(2 times legnth times width)+(2 times legnth times height)+(2 times width times height)=(2 times 12 times 10)+(2 times 12 times 16)+(2 times 10 times 16)=(2 times 120)+(2 times 192)+(2 times 160)=240+384+320=944 ft^2
then subtract the area of the door which is 3 times 8=24
so 944-24=920 ft^2
1 quart of paint =100
944/100=9.44
round up because you cant buy a fraction of a bucket but you still need to cover the whole room (minus the door)
10 quarts of paint is the answer
Answer:
X=19/32
Step-by-step explanation:
3/4^2+1^2=2*x
3/4^2+1=2x
3+(4^2)/4^2=2x
3+16/4^2=2x
19/4^2=2x
19/(2^2)^2=2x
19=16(2x)
19=16*2x
32x=19
32x/32=19/32
x=19/32
This took alot of time goodluck!
Answer:
a joke and a cartoon together cost $80
c=$15 j=$65
Step-by-step explanation:
j=joke
c=cartoon
8j +6c = 610
6j+8c = 510
Multiply the first by 8
Multiply the second by -6
64j +48c = 4880
-36j -48c = -3060
ADD both (c will cancel)
28j = 1820
j= 65
PLUG j
8(65) + 6c = 610
520+6c = 610
6c= 90
c = 15
j + c = 65+15 = 80
Answer:
c
Step-by-step explanation:
Because to make the same we have to have x as 1 which is x>0
