So this meeting room is 3 by 19 by 12
surface area/wall area=2(height times width)+2(height times depth)+2(width times depth)
lets say 3=height
depth=19
width=12
2(3 times 12)+2(3 times 19)+2(12 times19)=2(36)+2(57)+2(228)=72+114+456=642
2 coats of paint so surface area times 2
642 times 2=1284
assuming 30m means 30 <u>square</u> meters we divide 1284 by 30 and get
1284/30=42 and 4/5 or 42.8
then find how many cans by dividing by 4
42.8/4=10 and 1.4/2=10.7, but you cant buy 0.7 of a can so round up and get
11 cans of paint
he needs 11 cans of paint
Answer: if talking square root, it is sqrt3/2. if talking decimals, it is about 0.87.
Step-by-step explanation:
0 is neither positive nor negative. ... For example +5 indicates that the number lies to the right of 0 and -5 indicates that the number lies to the left of 0. Thus, integers are also called directed numbers. If a number has no sign it means that it is a positive integer.
Answer:
C (12+1/2) hours
Step-by-step explanation:
The picture represents the number of hours she spend watching tv for 2 weeks.
One day she watched for 0 hours.
One day she watched for 1/4 hours.
One day she watched for 1/2 hours.
Three days she watched for 3/4 hours.
Three days she watched for 1 hours.
Four days she watched for (1+1/4) hours.
One day she watched for (1+1/2) hours.
-----------------------------------------------------------
So for those two weeks (those 14 days) she watched
0+1/4+1/2+3(3/4)+3(1)+4(1+1/4)+1(1+1/2)
1/4+1/2+9/4+3+[4+1]+[1+1/2]
(1/2+1/2)+(3+4+1+1)+(1/4+9/4)
(1)+(9)+(10/4)
(1+9)+(5/2)
(10)+(5/2)
(20/2)+(5/2)
25/2
(12+1/2)
2x+3=17
subtract 3 from each side
2x+3 -3 = 17 -3
2x = 14
divide by 2 on each side
2x/2 = 14/2
x = 7
