Step-by-step explanation:
When measuring for floor tile the rule is:
Length x Width + Waste = Amount Needed
Waste Factor will vary based upon tile size, layout, configuration of room, patterns, etc. Typical waste factor is about 10%. Add 15% for tile being installed diagonally or for a room with lots of jogs and corners. These installations will require more cuts and thus more waste.

Answers
Answer:
B is the correct answer. I just took the test :))
Step-by-step explanation:
Option B is correct, Divide R₂ by 2 and R₃ by 3 is the next step in solving this augmented matrix using the Gauss-Jordan elimination method.
In the Gauss-Jordan elimination method, the goal is to transform the augmented matrix into row-echelon form and then into reduced row-echelon form to solve the system of linear equations.
To achieve this, we perform row operations on the matrix.
In the given augmented matrix:
[tex]\left[\begin{array}{ccc}1&0&0\\0&2&0\\0&0&3\end{array}\right] .\left[\begin{array}{c}5&8&9\end{array}\right][/tex]
We can divide R₂ (Row 2) by 2 and R₃ (Row 3) by 3 to simplify the matrix further we do this to make the leading coefficient (the number at the leftmost position in each row) of each row equal to 1, which is a requirement for row-echelon form.
After dividing R₂ by 2 and R₃ by 3, the augmented matrix becomes:
[tex]\left[\begin{array}{ccc}1&0&0\\0&1&0\\0&0&1\end{array}\right] .\left[\begin{array}{c}5&4&3\end{array}\right][/tex]

Answers
Answer:
Step-by-step explanation:
CD = 4sin30 = 4(1/2) = 2
∠BDC = 180 - 90 - 60 = 30°
BDcos30 = CD = 2
BD = 2/cos30 = 2/ (½√3) = 4/√3 = (4/3)√3
another way to do it would be
∠BDC = 180 - 90 - 60 = 30°
∠ADC = 180 - 90 - 30 = 60°
therefore
∠BDA = 60 - 30 = 30°
We can see the upper triangle is an isosceles triangle where lengths AB = BD and the angle between them is 180 - 30 - 30 = 120°
Using law of Sines
4/sin120 = BD/sin30
BD = 4sin30/sin120 = 4(½)/(½√3) = 4/√3 = (4/3)√3
or we could use the law of Cosines
c² = a² + b² - 2abcosC
BD² = AB² + 4² - 2(AB)(4)cos30
BD = AB = x
x² = x² + 4² - 2(x)(4)cos30
0 = 4² - 2(x)(4)cos30
4² = 2(x)(4)cos30
x = 4²/(2(4cos30)) = 2/cos30 = 2/ (½√3) = 4/√3 = (4/3)√3

Multiply (x +1) and x
= (x*x + x*1) * (3x +5)
= ( x² + x) * (3x + 5)
= x²*(3x +5 ) + x(3x +5)
=x²*3x + x²*5 + x*3x + x*5
= 3x³ + 5x² + 3x² + 5x
= 3x³ + 8x² + 5x

Answers
Answer:
Measure of angle A = 120°
Measure of angle B = 98°
Measure of angle C = 104°
Measure of angle D = 140°
Step-by-step explanation:
Find measure angle A :-Since the two straight lines are parallel
, then A + 12X =180° (alternate angles)
, then A = 180° - 12X
Since the two straight lines are parallel
, then measure angle A = measure angle (25X-5)°
(opposite angles)
, then 180° - 12X = 25X - 5° (solve it like a normal equation)
, then 180° + 5° = 25X + 12X
, then 185° = 37X
, then X = 185° ÷ 37
= 5
, then measure of angle A = 180° - ( 12 x 5 )
= 180° - 60°
, then measure angle A = 120°
Find measure angle B :-Since the two straight lines are parallel
, then measure angle B = measure angle 14X (corresponding angles)
, then 15X - 7 = 14X
, then 15X - 14X = 7
, then X = 7
Since X =7
, then measure angle B = (15 x 7) - 7
= 105° - 7
, then measure angle B = 98°
Find measure angle C :-Since the two straight lines are parallel
, then measure angle C = 8X
(opposite angles)
, then 5X + 39 = 8X
, 39 = 8X - 5X
, 39 = 3X
, then X = 39 ÷ 3
, X = 13
Since X = 13
, then measure angle C = (5 x 13) +39
= 65 + 39
, then measure angle C = 104°
Find measure angle D :-Since straight that angle D lies on = 180°
, then sum of measure of and D and 4X =
180°
, then (12X + 20) + 4X = 180°
, then 16X + 20 = 180°
, then 16X = 160° (resulting from 180° - 20°)
, then X = 10
Since X = 10
, then 12 x 10 + 20 = 120 + 20
,the measure angle D = 140°
