Carlos paid an electrician x dollars per hour for a 4-hour job and $85 for parts. The total charge was $305. Which equation can be used to determine how much the electrician charged per hour?
Answer:
55
Step-by-step explanation:
The equation would be:
305=85+4x
220= 4x
x= 55
Answer: 4x + 85 = 305
To get your answer you just have to subtract 85 from 305 (I believe) and then divide what you got by four :)

x² + 9y² = 9
(a) About
y = 3
(b) About
x = 3
Answer:
a) the volume of solid revolution is 18π² = 177.652879 ≈ 177.65288
b) the volume of solid revolution is 18π² = 177.652879 ≈ 177.65288
Step-by-step explanation:
a) the volume of solid of revolution
about y=3
Using SHELL METHOD;
Volume V = 2π . [tex]\int\limits^1_{y=-1} \,[/tex] (3-y) (2.3√(1-y²)) dy
= 12π . [tex]\int\limits^1_{y=-1} \,[/tex] (3-y) √(1-y²) dy
= 12π . [tex]\int\limits^1_{y=-1} \,[/tex] (( 3√(1-y²) - y(√(1-y²)) dy
= 12π[ [tex]\frac{3}{2}[/tex]π - 0 ]
= 18π² = 177.652879 ≈ 177.65288
Therefore, the volume of solid revolution is 18π² = 177.652879 ≈ 177.65288
b)
the volume of solid of revolution
about x=3
Using SHELL METHOD;
Volume V = [tex]\frac{4}{3}[/tex]π . [tex]\int\limits^3_{y=-3} \,[/tex] (3-x) ([tex]2.\frac{1}{3}[/tex]√(9-x²)) dx
= [tex]\frac{4}{3}[/tex]π . [tex]\int\limits^3_{y=-3} \,[/tex] (3-x) √(9-x²) dx
= [tex]\frac{4}{3}[/tex]π . [tex]\int\limits^3_{y=-3} \,[/tex] (3√9-x² -x√(9-x²) dx
= [tex]\frac{4}{3}[/tex]π [ [tex]\frac{27}{2} \pi[/tex] - 0 ]
= 18π² = 177.652879 ≈ 177.65288
Therefore, the volume of solid revolution is 18π² = 177.652879 ≈ 177.65288

QUESTION SORRY ITS SMALL*
Answer:
Taylor charges $5 more than Lucy for 2.5 hours.
Step-by-step explanation:
You need to find how much Taylor charges for 2.5 hours and how much Lucy charges for 2.5 hours.
Taylor:
$15 for first hour and then $10 for each hour r fraction of an hour.
Taylor charges $15 for the first hour.
Then the time remaining is 2.5 hours - 1 hour = 1.5 hours.
The charge for an hour or fraction of an hour after the first hour is $10 per hour.
1.5 hours * $10/hour = $15
Total charge for Taylor: $15 + $15 = $30
Lucy:
Lucy charges according to the function that we are shown.
According to the function, we need the middle equation since that is the one that includes 2.5 hours which is between 2 and 4 hours.
Th function that includes x = 2.5 hours is
f(x) = 10x
Since the number of hours is 2.5, then x = 2.5, and we evaluate the function for x = 2.5.
f(x) = 10x
f(2.5) = 10(2.5)
f(2.5) = 25
Lucy charges $25 for 2.5 hours.
Taylor charges $30. Lucy charges $25.
The difference is $30 - $25 = $5.
Answer: Taylor charges $5 more than Lucy for 2.5 hours.
2/5 kilogram of soil fills 1/3 of a countainer. Can 1 kiligram of soil fit in the container?

a city receives 3 inches of snowfall every 6 hours. write and graph a function that describes the relationship.
Answer:
Step-by-step explanation:
The function to represent the given scenario is f(x)=3x/6.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Given that, a city receives 3 inches of snowfall every 6 hours.
Let y represent the height of the snow after x hours. The city receives 3 inches of snowfall every 6 hours.
So, the function is y = 3x/6
f(x)=3x/6
For 1 foot of snow (12 in):
12 = 3x/6
3x = 72
x=24 hours
Therefore, the function to represent the given scenario is f(x)=3x/6.
