Well 10.30 x 5 = $51.50 and then half an hour would be $5.15 so that’s $56.65 for the hours. then plus the 3.75 that’s $60.40. and then minus the 4.50 that’s $55.90

Answer:

$55.90

Step-by-step explanation:

First, create an equation representing her earnings each day.

Let x represent the number of hours that she walks the dog.

Since she charges $10.30 per hour, the cost from walking is 10.3x

She also charges $3.75 as a base fee, which has to be added

Putting this together, we get the equation y = 10.3x + 3.75

Plug in 5.5 as x to find her earnings:

y = 10.3x + 3.75

y = 10.3(5.5) + 3.75

y = 60.4

Since the spends $4.50 on dog treats a day, we have to subtract this from her earnings:

60.4 - 4.5

= 55.9

So, if she works for 5.5 hours, she will earn $55.90

Five carpenters worked 15 & 3/4, 15 & 1/4, 17 & 1/2, 12 & 1/2 and 17 & 1/2 hours respectively. What was the
azamat

<u>The total </u><u>labor cost</u><u>  of the carpenters is $2296.91</u>

The carpenters worked 15\frac{3}{4} , 15\frac{1}{4}, 17\frac{1}{2}, 12\frac{1}{2}, 17\frac{1}{2}

<h3>Conversion of Fraction</h3>

Let's convert the mixed fraction to improper fraction

So, we would have

  • 63/4,
  • 61/4,
  • 35/2,
  • 25/2
  • 35/2.
<h3>Working Cost</h3>

Let's sum it up and multiply by the working cost per hour

63/4 + 61/4 + 35/2 + 25/2 + 35/2 =78.5

  • The total labor cost is = total hours worked * hourly rate.

This becomes 78.5*29.26=2296.91

<u>The total labor cost is $2296.91</u>

What are the coordinates of the fourth point that could be connected with (–8, 0), (1, 0), and (1, –5) to form a rectangle?
sergey [27]
(-8, -5)

To form a rectangle, all the lines must be perpendicular and parallel. If you draw out the points on a coordinate plane then you can find the answer pretty easily. 

Also, this one is easy because all the lines are vertical or horizontal, and when that is the case then you can just see which number in the set hasn't appeared twice (1 appeared twice as an <em>x</em> value, 0 appeared twice as a <em>y </em>value, but -8 has only appeared once as an <em>x</em> and -5 has only appeared once as a <em>y </em>value)
