NEED HELP! worth 10 points:)a house painting company charges $376 plus $12 per hour .Another painting company charges $280 plus $15 per hour. (a)how long is a job for which both companies will charge the same amount?(b) what will that cost be?

Answers

Answer 1

Answer: x equals number of hours
company 1: 376+12x
company 2: 280+15x
set them equal to each other to get the amount of hours
376+12x=280+15x >>> than subtract 280 from both sides
-280 -280 that equals
96+12x=15x than subtract 12x from both sides
-12x -12x
96=3x than divide the whole equation by 3
32=x
(a) 32 hours
and to get part b just plug the 32 into one of the equations
376+12(32)
376+384
760
(b) $760
if you plug it into the other equation you get the same answer so that means that the answer is correct
I hope this helps

You are paid $78 for 6 and a half hours of work. What is your rate of pay?

Answers

The most important part of the problem lies in the fact that the hours have to be converted to minutes before starting to solve the problem.
1 hour = 60 minutes
6 and half hours = (6 * 60) + 30 minutes
   = 360 + 30
   = 390 minutes
So the payment for 390 minutes is = 78 dollars
Then
The payment for 60 minutes = (78/390) * 60
   = 2 * 6 dollars
   = 12 dollars
So the rate of pay given is $12 per hour. I hope the procedure is easy enough for you to understand. You can always use this method for solving similar type of problems.

$78/ (6 1/2 hours)= $12/hour.

The rate of pay is $12 per hour~

Richard walks every day for exercise at a rate of 1 kilometer every 12 min. At this rate ,how many meters can Richard walk in a hour? please helppppppp

Answers

Answer: He can walk 5000 meters in one hour.

Step-by-step explanation:

According to the question,

$\text{ The distance he covered in 12 minutes }=\text{ 1 km}$

$\text{ The distance he covered in 60 minutes }=\text{ 5 km}$

$\text{ The distance he covered in 1 hour }=\text{ 5 km}$

Now, 1 km = 1000 meters,

$\implies \text{ The distance he covered in 1 hour }=\text{ 5000 m}$

60 minutes in an hour
60÷12=5
1,000 meter in 1 km
5×1=5
5×1000=5000
therefore, 5000 meters

Your teacher divides the class into two groups of the same size by picking names at random from the class, and you will be in group 1? A. impossible B. unlikely C. as likely as not D. Likely E. certain

Answers

Answer:

C. as likely as not

Step-by-step explanation:

The teacher makes two groups with the same number and divides the student at random. The two groups have equal size, so the chance for someone to get picked into group 1 is 100%/2= 50%. The chance for someone to get picked into group 2 will be also 100%/2= 50%

The chance to get picked to be in group 1(50%) is the same as the chance to NOT get picked into group 1(50%). The word to explain this chance will be "as likely as not".
