A plumber charges a fixed rate of $40 per job plus $10 for each hour, h, that he works at the job. Which equation models the total amount the plumber charges, y, if he works h hours?
Answer:
it says how many total so i know we are doing addition we are going to add 40+10=50 so the answer is $50 dollars he charges.
You have the opportunity to run the helium balloon stand at the Alexander County Fair. Your start-up supplies will cost $60. It will cost $.05 to fill each balloon you sell with helium. You are going to sell each balloon for $1.25. Find your break-even point. How many balloons will you need to sell in order to break- even?
Answer:
50
Step-by-step explanation:
1.25 - .05 = 1.20 made per balloon
60/1.2 = 50 balloons sold to recoup 60$ start up and break even
2t + 8 is greater than or equal to -4 ( t + 1 ), whats the answer to the equation?
Step-by-step explanation:
2t + 8 > - 4( t + 1)
2t + 8 > - 4t - 4
2t + 4t < - 4 +8
6t < 4
Divide both sides by 6
T < 4
6
t < 2
3
I think that is the answer

There are 3 points on the plane.Explain or determine whether point C is closer to point A or point B.
Point C us closer to point B because if you connected the points B would be in the middle of C going to A line.
Step-by-step explanation:
I hope I helped!
The perpendicular line from a point to a line is the shortest distance from the point to the line
With regards to the three points on the plane, point C is closer to point B
The reason point C is closer to point B is as follows:
The known parameter is;
Three points, A, B, and C, are located on a plane
Required:
To explain or determine whether point C is closer to point A or point B
Method:
Define, the relationship between the destination points A, and B
Find the shortest distance from point C, to the definition of points A, and B
Solution:
The relationship between points A, and B is that they form the line segment AB
The shortest distance from a point C to a line segment AB in Euclidean geometry is the perpendicular distance from the point C to the line segment AB
The line which best approximates the perpendicular line and therefore,
shortest distance from C to AB is the line segment CB
CB represents the shortest line and therefore distance from C to AB, that is
CB is shorter than line segment CA and which shows that it is shorter to go
from C to B, than from C to A or point C is closer to point B than point A

Karen bought cupcakes for her sister's birthday party. 3 cupcakes had sprinkles on top. The other 27 cupcakes did not have sprinkles. What percentage of the cupcakes had sprinkles?
Answer:
10%
Step-by-step explanation:
so
3 cupcakes had sprinkles
27 didn't have sprinkles
which means that there are a total of 30 cupcakes, (because 3 + 27 is 30)
so then set up a proportion
part/whole = percent/one hundred
substitute in the given values
3 / 30= precent/100
simplify
1/10 = precent/100
you don't have to use cross products here because it is pretty obvious that 10 * 10 = 100 so then just multiply 1/10 by 10 and you get your answer
percent = 10

Answer:
12 weeks
Step-by-step explanation:
every 5 weeks marcus lost 7.5 pounds (232 - 224.5)
or 1.5 per week
so 232 - 214 (start to goal) is a total of 18 pounds
18/1.5 = 12 weeks

I need help finding the values of x and y!!
Answer:
x= 22
y = 35
Step-by-step explanation:
The base angles of a isosceles triangle are equal
3x-11 = 2x+11
Subtract 2x from each side
3x-2x -11 = 2x-2x+11
x-11 = 11
Add 11 to each side
x-11+11 = 11+11
x = 22
The sum of all the angles in a triangle is 180
3x -11 + 2x+11 + 2y = 180
Combine like terms
5x +2y = 180
5*22 + 2y = 180
110 + 2y = 180
Subtract 110 from each side
110+2y-110 = 180-110
2y = 70
Divide by 2
2y/2 =70/2
y = 35

1.The growth of a sample of bacteria can be modeled by the function b(t)=100(1.06)t where b is the number of bacteria and t is time in hours.
What is the number of total bacteria after 3 hours?
Given:
The growth of a sample of bacteria can be modeled by the function
[tex]b(t)=100(1.06)^t[/tex]
where, b is the number of bacteria and t is time in hours.
To find:
The number of total bacteria after 3 hours.
Solution:
We have,
[tex]b(t)=100(1.06)^t[/tex]
Here, b(t) number of total bacteria after t hours.
Substitute t=3 in the given function, to find the number of total bacteria after 3 hours.
[tex]b(t)=100(1.06)^3[/tex]
[tex]b(t)=100(1.191016)[/tex]
[tex]b(t)=119.1016 [/tex]
Therefore, the number of total bacteria after 3 hours is 119.1016.
Parallel to y=-3x+4, x-intercept at 4
Answer:
y = -3x + 12
Step-by-step explanation:
The slope of parallel line is the same as the original line.
If the x-intercept is 4, this as a point can be stated as (4, 0)
We can now solve for the y-intercept.
y = -3x + b
0 = -3(4) + b
0 = -12 + b
12 = b
Put everything we solved for back into the formula [ y = mx + b ]
y = -3x + 12

A. 23/24
B. 1 1/4
C. 3 1/4
D. 3 11/24
Answer:
[tex]3\frac{11}{24}[/tex]
Step-by-step explanation:
Given parameters:
Leftover pizza from the Science club = [tex]1\frac{1}{4}[/tex]
Left over pizza from french club = [tex]2\frac{5}{24}[/tex]
Unknown;
Total left over pizzas between the two clubs = ?
Now to solve problem, simply add the leftover from the science club and the french club together;
Total left over pizza = [tex]1\frac{1}{4}[/tex] + [tex]2\frac{5}{24}[/tex]
= [tex]\frac{5}{4} + \frac{53}{24}[/tex]
= [tex]\frac{83}{24}[/tex]
