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

Answers

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.

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.​

Answers

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.

Question 15

Answers

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°

Answers

Answer:

Step-by-step explanation:

the shape looks like a cube.. and maybe they say something about that outside of the picture, even but assuming that it is a cube, we know all the sides are the same.

we also know that the area of one side of the cube is  3 [tex]\frac{1}{4}[/tex]

so multiply that  

W x L = area

 3 [tex]\frac{1}{4}[/tex] * 3 [tex]\frac{1}{4}[/tex] = area

10 [tex]\frac{9}{16}[/tex]  = area

10.5625 = area

those two answer above are the same .. just one is in fractions and one is in decimals

there are 6 sides on a cube, so multiply the above answer by 6

6* answer = 63.375

63 [tex]\frac{3}{8}[/tex]  ( this is your answer)

both of those are also identical , but look different for the reasons I mentioned above

use which ever from seems better to you.  :)
