if Georgia and Farrah work together, it takes them 8 minutes to clean the espresso machine at their coffee shop Alone, Farrah takes 12 minutes
less than Georgia to clean the machine if x is the number of minutes it takes Georgia to clean the machine by herself, the situation can be
represented by this equation
How long does it take Georgia to clean the espresso machine by herself?
4 minutes
10 minutes
20 minutes
24 minute
Answer:
The answer is 24 minutes
Step-by-step explanation:
It takes 24 minutes for Georgia to clean the espresso machine by herself. Therefore, option D is the correct answer.
The equation of the given situation is [tex]\frac{1}{x}+\frac{1}{x-12}=\frac{1}{8}[/tex].
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The given equation [tex]\frac{1}{x}+\frac{1}{x-12}=\frac{1}{8}[/tex] can be solved as follows
LCM of denominators x and x-12 is x(x-12)=x²-12x
Now, [tex]\frac{x-12+x}{x^2-12x} = \frac{1}{8}[/tex]
8(2x-12)=x²-12x
⇒ 16x-96=x²-12x
⇒ x²-12x-16x+96=0
⇒ x²-28x+96=0
Using splitting middle term method
x²-24x-4x+96=0
⇒ x(x-24)-4(x-24)=0
⇒ (x-24)(x-4)=0
⇒ x=24 or 4
It takes 24 minutes for Georgia to clean the espresso machine by herself. Therefore, option D is the correct answer.

Answer:
∠1 = 42°
∠2 = 48°
∠4 = 48°
∠3 = 21°
∠5 = 21°
Step-by-step explanation:
Given:
∠WZY = 138°
Find:
∠1
∠2
∠3
∠4
∠5
Computation:
WZ = ZY
So,
∠3 = ∠5
So,
∠3 + ∠5 + 138 = 180
2∠3 = 42
∠3 = 21°
∠5 = 21°
∠1 = 180 - 138
∠1 = 42°
∠W = ∠Y
∠X + ∠Y + ∠W = 180
42 + ∠Y + ∠W = 180
∠Y = 69
∠2 = 69 - 21
∠2 = 48°
∠4 = 48°

The outside diameter (od) of a pipe is 4 9/32 inches. The walls are 7/32 inches thick. find the inside diameter.
Please explain how you got your answer.
The inside diameter would be the outside diameter minus 2 of the wall thicknesses.
4 9/32 - (2 x 7/32)
Simplify:
4 9/32 - 14/32
Because 14/32 is larger than 9/32 change one of the hole numbers to a fraction: 1 = 32/32
rewrite 4 9/32 as 3 41/32
Now subtract:
3 41/32 - 14/32 = 3 27/32 inside diameter.

9514 1404 393
Answer:
31.243 units
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relationships between sides and angles in a right triangle. Using the attached figure, it is convenient to find the length of BE as an intermediate step in the solution.
Sin = Opposite/Hypotenuse
sin(30°) = BE/100
BE = 100·sin(30°)
Then ...
Tan = Opposite/Adjacent
tan(58°) = BE/x
x = BE/tan(58°) = 100·sin(30°)/tan(58°)
x ≈ 31.243 . . . . units
_____
Comment on the figure
The intermediate problem in creating the figure was to locate point D. That was accomplished by locating point C on a line at an angle of 58° CCW from the horizontal, using point B as a center. Then D is the intersection of BC with the x-axis. BE is drawn perpendicular to the x-axis.
