PLEASE HELP ASAP

Maria recently hired a plumber to do some necessary work. On the final bill, Maria was charged a total of $473. The amount listed for parts was $335 and the rest of the bill was for labor. If the hourly rate for labor was $46, how many hours of labor was needed to complete the job?

(A) First write an equation you can use to answer this question. Use x as your variable. The equation is __________________

(B) Solve your equation in part (A) to find the number of labor hours needed to do the job. Answer: The number of labor hours was ________________________

Answers

Answer 1

Answer:

A)473 = 335 - 46x

B) 3

Step-by-step explanation:

A)

473 = 335 - 46x

x = the hours of labor needed.

B)

Solve for x

473 = 335 - 46x

subtract 335 from both sides

138 = 46x

divide both sides by 46

3 = x

Answer 2

Answer:

A) [tex]46x+335=473[/tex]  B)[tex]x=3[/tex]

Step-by-step explanation:

473 is the total amount, which means it is the end result

335 represents a constant since it is a base price

the hourly rate is a variable, due to the fact that it depends on how many hours he spent working.

variable + constant = total price

[tex]46x+335=473[/tex]

Now to solve this, first subtract [tex]335[/tex] from both sides

[tex]46x=138[/tex]

Next divide both sides by [tex]46[/tex] to isolate the variable

[tex]x= \frac{138}{46}[/tex]

This can be simplified to: [tex]x=3[/tex]

For the given central angle, determine the distance traveled along the unit circle from the point (1, 0). 360 degrees a. 6.28 units clockwise c. 3.14 units clockwise b. 6.28 units d. 3.14 units

Answers

Answer:

The length of a 180° arc of a unit circle is π ≈ 3.14 units.

Step-by-step explanation:

Use your knowledge of the circumference of a circle (the length full around) and the fact that there are 360° in the central angle of a full circle. The distance around is proportional to the angle, so an arc of measure 180° will have a length equal to

... (180°/360°) × circumference = (1/2)×circumference

For a unit circle, the circumference is 2π (= π×diameter = 2π×radius). Half that length is π units.

Answer:

I can't give a "smart" explanation but the answer is D) 3.14 units

Zac is 18 years old.
The ratio of Zac's age to Ed's age is 2:1.
Tim's age is 2/3 Zac's age.
How old is Tim?

Answers

Answer:

Tim is 12 years

Step-by-step explanation:

Given that Zac is 18 years old and Tim's age is 2/3 Zac's age, to compute Tim's age, we would multiply Zac's age with the fraction.

Such that;

Tim's age = 2/3 * 18

= 2* 18/3

= 2 * 6

= 12 years

Hence Tim is 12 years old.
