Answer: As given, relationship between the number of hours a plumber works and the total work fee she charges is proportional.
The meaning of proportional is Ratio of number of hours a plumber works and the total work fee she charges is constant.
Using Unitary method
5 hours of work = $350
1 hours of work = $70
Let number of hours worked = x hours
Amount earned for x hours of work is represented by = $ y
For , x hours of work amount earned = 70 x (x=1,2,3...)
→y= 70 x
→→

Answer:
The answer to your question is below
Step-by-step explanation:
Data
Volume = 270 cm³
height = 5 cm
length = ?
width = ?
Formula
Volume of a rectangular prism = height x length x width
- Solve for Area of the base (height x length)
Area of the base = Volume / height
-Substitution
Area of the base = 270 / 5
-Result
Area of the base = 54 m²
2.- Find the prime factors of 54
54 2
27 3
9 3
3 3
1
3.- The possible values of the sidas of the rectangle are:
Combining the prime factor of 54.
Length Width
2 x 3 = 6 and 3 x 3 = 9
or 2 x 3 x 3 = 18 and 3 x 1 = 3
or 3 x 3 x 3 = 27 and 2 x 1 = 2
Answer:
<em>the unit rate is 0.8x per unit y</em>
<em></em>
Step-by-step explanation:
the proportional relationship is y = 
this means that the constant of proportionality k = 
= 0.8
re-writing, we have
<em>y = 0.8x</em>
<em>therefore, the unit rate is 0.8x per unit y</em>
Answer:
I believe that the owner of the dice is actually not lucky. There are people who practice throwing dice in a controlled way in order to get a specific side of the dice. If he practices his dice throwing a lot, then he would have a much higher chance of winning at a game of dice.
Step-by-step explanation:
Since you said he was lucky, I decided to make an answer saying that he wasn't lucky so you can choose between both of them. Your answer was good as well.
Answer:
4 13/16
Step-by-step explanation:
6 3/7 - 1 3/6 =
270/42 - 63/42 = 207/42 = 4 39/48 = 4 13/16
