Answer:
205.75
Step-by-step explanation:
first, separate the floor into 3 different rectangles to calculate the area and then add them together.
area of rec=L*B
rec 1: 11.5*8=92
rec 2: (12.5-5)*(18.5-8-7)=26.25
rec 3:7*12.5=87.5
Then:
92+26.25+87.5=205.75
Answer:
yes
Step-by-step explanation:
Multiply both sides by 8 (to undo the division of 8)
x/8 < 10
8(x/8) < 8*10
x < 80
So any number less than 80 will make the original inequality true. This applies to choices: C, D, E which are the final answers. These values are all less than 80.
---------------------------------
Alternatively we can plug in each value into the inequality to check them
Choice A
x/8 < 10
80/8 < 10
10 < 10
false; choice A is eliminated
-------
Choice B
x/8 < 10
96/8 < 10
12 < 10
false; choice B is eliminated
-------
Choice C
x/8 < 10
64/8 < 10
8 < 10
true; choice C is one of the answers
-------
Choice D
x/8 < 10
40/8 < 10
5 < 10
true; D is another one of the answers
-------
Choice E
x/8 < 10
32/8 < 10
4 < 10
true; choice E is another solution
-------
Choice F
x/8 < 10
88/8 < 10
11 < 10
false; choice F is eliminated
---------------------------------
Whichever method you end up using, the final answers are C, D, E
Answer:
1. The greatest common monomial factor is xy
2. xy(6 + 2y² + 3x²)
Step-by-step explanation:
6xy + 2xy³+ 3x³y
1. Determination of the greatest common monomial (GCM) factor.
6xy + 2xy³+ 3x³y
6xy => 2 × 3 × x × y
2xy³ = 2 × x × y × y × y
3x³y = 3 × x × x × x × y
GCM => xy
2. Rewrite the expression
6xy + 2xy³+ 3x³y
GCM => xy
6xy + 2xy³+ 3x³y = xy(6 + 2y² + 3x²)
In the sequence you divide each number by 2 so the ratio is 1/2 or 1:2
