Write an equation for the following problem.

The cost of a babysitting service on a cruise is $10 for the first hour and $12 for each additional hour. If the total cost of

babysitting baby Aaron was $58, how many hours was Aaron at the sitter?


12x+10=58

10x+12=58


12x-58=10


10x+58=12

Answers

Answer 1

Answer:  Aaron was at the sitter for 5 hours

Step-by-step explanation:

12x + 10 = 58

the 12x is for each hour after the first hour and the 10 is the first hour

-10 from each side

12x = 48

/12

x = 4

4 additional hours plus the original hour

Answer 2
Answer: 12x+10=58

Explanation: $10 is the flat rate, so it only applies to one of the hours. It is not being multiplied by anything. Her hourly rate after that is $12 meanings the amount of money she makes depends on how many hours she works which is x. $58 is the end result so that is what the equation equals.

A dog walker service offers a daily service and a weekly service in the winter the ratio of daily customers to weekly customers was one to five however in the spring more customers moved to the daily service because of the nicer weather after the weather changed the ratio was 4:2 if there were 1:5weekly customers in the winter then how many daily customers were there in the spring

Answers

Answer:

Daily customers were there in the spring = 100 customers

Step-by-step explanation:

In winter :

Daily customers to weekly customers = 1:5

In spring

Daily customers to weekly customers = 4:2

And total weekly customer in winter = 125

Find:

Daily customers were there in the spring

Computation:

Total customer in winter = 125[6/5]

Total customer in winter = 150

Daily customers were there in the spring = 150 [4/6]

Daily customers were there in the spring = 100 customers

Can I plz get the congruence and reason plz

Answers

Congruence is when there are 2 objects that have the same shape and size, or they "mirror" each other.

Question 6:

Congruence:

Yes, these two objects are congruent.

Reason:

They are congruent, because they have the same size and shape, or that they  "mirror" each other.

Question 7:

Congruence:

Yes there is congruence, here. These two objects are similar shapes, but not completely congruent.

Reason:

These two objects have the same size, but not the exact same shape. If you look at point B you can see that the two angles are different, which means that they are similar shapes, but not completely congruent.

Help pls guys!!!asap

Answers

Answer:

The answer is D

Step-by-step explanation:

This problem may look complex but it isn't; the variables in the "x" column represent what would be substituted for x, and y would be what the equation would equal AFTER substituting the x variable into the equation

So for example, using d's table, I would substitute -4 for x: y = -3(-4) + 2, the answer would be 14, which is in the y column. I will do the same thing using the next variable in the x column, y = -3(-2) + 2, that would equal 8, which is also in the y column, this would not serve true in any other tables.

An angle measures 130.4° more than the measure of its supplementary angle. What is the measure of each angle?

Answers

Answer: 24.8 and 155.2

Step-by-step explanation:

x+x+130.4=180

2x=49.6

x=24.8

Answer:

155.2

Step-by-step explanation:

let x be the supplimentary angle

then the angle is

130.4+x

we have

 

130.4+x+x=180

2x=49.6

multiply both sides with 2

x=24.8

then the angle is

130.4+24.8

WORTH 15 POINTS!! - Eileen's Energy Bars has determined that an energy bar measuring 3.25 inches long has a z-score of +1 and an energy bar measuring 3.50 inches long has a z-score of +2.

What is the standard deviation of the length of energy bars produced at Eileen's Energy Bars?

3.5
3.25
0.75
0.25

Answers

Answer:

0.25

Step-by-step explanaition:

The z-score represents how many deviations a value is from the mean. When the bar measures 3.25, the z-score is +1. When the bar measures 3.50, the z-score is +2. You'll notice that whenever the bar size increases by 0.25, the z-score goes up +1. So, the standard deviation from the mean must be 0.25.
