The area of the ceiling:
A = 14² = 196 ft²
We need plaster to cover 196 ft².
196 : 90 = 2.17778
Answer: We have to buy 3 pails of plaster.
Answer:

Step-by-step explanation:
OK, so basically I'm pretty sure that you add all of them together and put it as a fraction over 3 so basically
then simplify it into 
Answer:
(1) 20%
Step-by-step explanation:
→ Find the difference in price
200 - 160 = 40
→ Divide difference by original price
40 ÷ 200 = 0.2
→ Multiply the answer by 100
0.2 × 100 = 20%
Scientific notation is just rewritten so that it has a single digit in front of the decimal and that this is multiplied by a power of ten that makes this decimal equal to the original number.
In this case we have 2.67 million. Well a million is equal to 10^6, because 10*10*10*10*10*10=one million.
So in scientific notation you would write:
2.67X10^6
Hello :)
The first one would be a rotation because it was easily rotated upward , it looks like it was rotated maybe 90°, The second one would be translation because it is simply moved upward and moved slightly to the right without be resized, rotated, or anything. The third one would definitely be a reflection because it appears to be flipped across the x axis. The fourth one i'm not really sure but i'm going to guess it is a rotation because it is turned in a different direction from the original figure.
