frankie can build a speaker box in 120 minutes trash can build a speaker box 40 minutes faster if they work together how many minutes does it take them to build the speaker box

Answers

Answer 1

9514 1404 393

Answer:

48 minutes

Step-by-step explanation:

Each minute, F can build 1/120 of a speaker box, and T can build 1/80 of a speaker box. Working together, in 1 minute, they can complete ...

1/120 + 1/80 . . . . . speaker boxes

= 2/240 +3/240 = 5/240 = 1/48 . . . . speaker boxes

Then there will be 1 complete speaker box after 48 minutes.

Answer:

329/9, the answer seems wrong but I triple checked because I thought so too. The answer is 100% correct

Step-by-step explanation:

Angle EFG + Angle FGH + Angle GEF = 180 degrees

(2x+1) + (6x+2) + (x + 19) = 180 degrees

9x + 22 = 180 degrees

9x = 158 degrees

x= 158/9

x+19 = Angle GEF

158/9 + 19 = Angle GEF

329/9 =Angle GEF

Double check:

(2x+1) + (6x+2) + (x + 19), x=158/9

2(158/9) + 1 = 325/9

6(158/9) +2 = 322/3

(158/9) +19 = 329/9

325/9 + 322/3 + 329/9 = 180

A gum tree reached a height of 150 ft in 15 years. Cathy and Darla write different equations to find the yearly average growth g of the tree. Cathy writes 15g = 150. Darla writes 150/15 = g. Do these equations have the same solution? Explain.

Answers

Answer:

Yes, they have the same answer because because 150/15 = 10 and in the equation 15g = 150, you have to solve it by dividing 150 by 15 which gets 10. Therefor, they are the same.

Step-by-step explanation:

Answer: They have the same solution.

Step-by-step explanation: 15g=150 has an answer of 10 ft. (divide 150 by 15 to get g alone.) 150/15=g has an answer of 10 as well. (Simplify to find g.)

What is f(−1) for the function given? f(x)=x2−3x+8

Answers

Answer:

Step-by-step explanation:

I am assuming you are asking for f(x)=x^2-3x+8? You plug (-1) in for all portions of x. This means you get (-1)^2-3(-1)+8. (-1)^2 is simply 1 because -1 x -1=1. 3*-1 is -3. This makes the equation 1 - (-3) + 8. The middle section simplifies down to +3 making it 1+3+8, or 12.

Mr. Johnson currently has a square garden. He wants to redesign his garden and make it into a rectangle with a length that is 5 feet shorter than three times its width. He decides the perimeter should be 70. PLEASEEEEE ITS URGENT

Answers

Answer:

Width of the rectangle = 10 feet

Length of the rectangle = 25 feet

Step-by-step explanation:

Perimeter of a rectangle = 2(length + width)

Let

Width of the rectangle = x feet

Length of the rectangle = 3x - 5 feet

Perimeter of the rectangle = 70 feet

Perimeter of a rectangle = 2(length + width)

70 = 2{x + (3x - 5)}

70 = 2{x + 3x - 5}

70 = 2(4x - 5)

70 = 8x - 10

70 + 10 = 8x

80 = 8x

Divide both sides by 8

x = 80 / 8

= 10

Width of the rectangle = 10 feet

Length of the rectangle = 3(10) - 5

= 30 - 5

= 25 feet

4x+3/7+2=x+5/2

Answers

Answer:

x= 1/42

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4x+3/7+2=x+5/2

combine like terms (2 and 3/7)

4x+17/7=x+5/2

Step 2: Subtract x from both sides.

4x-x+17/7=x-x+5/2

3x+17/7=5/2

Step 3: Subtract 17/7 from both sides.

3x+17/7−17/7=5/2-17/7

3x=1/14

Step 4: Divide both sides by 3.

3x/3=1/14/3

1/14 * 1/3 = 1/42

x=1/42
