Answer:
510.84 ft²
Step-by-step explanation:
Given that,
dimensions of wall = 12.9ft by 9.9ft
height of wall = 12.9ft
width of wall = 9.9ft
there are total 4 walls in a bedroom to be painted blue.
Formula to calculate area of one wall
<h3>Height x Width</h3>
Formula to calculate area of four walls
<h3>4 (Height x Width)</h3>
= 4( 12.9ft x 9.9ft)
= 4 (127.71 ft²)
= 510.84 ft²
So area Alyssa will paint = 510.84 ft²
<em>(assuming she will paint only wall s of her room not the ceiling)</em>

Do you have a specific question we could solve?
Answer:
Option (E) 648
Step-by-step explanation:
the 3 digit number can be represented by the blanks as " _ _ _ "
Now,
we have 10 choices ( i.e 0,1,2,3,4,5,6,7,8,9) available for each place in the blank if no condition is applied.
For the hundreds digit, using the conditions given in the question, we have 8 choices left
as 1 and 0 cannot be included in the hundreds place.
for the tens place
we will have 9 choices left out of 10 ( as 1 choice is less because we cannot have same number as on the hundred place )
similarly, for the ones place we have 9 choices left out of 10 ( as 1 choice is less because we cannot have same number as on the tens place )
Therefore,
Total possibilities = 8 × 9 × 9 = 648
Hence,
Option (E) 648
Slope intercept looks like this:
y = ax + c
So:
-5y = 9x + 35
We need to isolate y, so divide both sides by -5:
y = - 
x - 7
Answer:
20%
Step-by-step explanation:
When you divide 40 by 8, you get 0.2. To convert a decimal into a percent, you multiply by 100 to get 20.
Hence,
8 is 20% of 40.
