Answer:
Average (additional) income = 100 - 50/x
Step-by-step explanation:
Ryan's additional income = 100x - 50 , where x = quantity of colored watch bands
Ryan's additional average income = Income / Quantity of watches sold
(100x - 50) / x
= 100 - 50/x

Logan is working two summer jobs, making $18 per hour tutoring and making $10 per hour clearing tables. In a given week, he can work a maximum of 13 total hours and must earn at least $170. If xx represents the number of hours tutoring and yy represents the number of hours clearing tables, write and solve a system of inequalities graphically and determine one possible solution.
Answer: he could work 7 hours tutoring and 6 hours clearing tables
Step-by-step explanation:
The system of inequalities can be used to find the number of hours Logan
can spend on each job in a week.
Response:
The system of inequalities are;
x + y ≤ 1318·x + 10·y ≥ 170A possible solution of the system of inequality obtained from the graph is the point (5, 8)
x = 5, and y = 8Methods used to solve the inequality graphicallyThe amount Logan makes per hour tutoring = $18 per hour
The amount he makes clearing tables = $10 per hour
Number of hours Logan can work in a week = 13
Amount he must earn in a week = At least $170
Number of hours he spends tutoring = x
Number of hours he spends clearing tables = y
Based on the given information, we have;
x + y ≤ 1318·x + 10·y ≥ 170Please find attached the graph of the above inequality showing the feasible region.
A possible solution obtained from the feasible region is the point of intersection of the two inequalities which is the point (5, 8), which gives;
A possible solution is x = 5, y = 8Therefore, Logan can spend 5 hours tutoring and 8 hours clearing tables in a week to work for 13 hours and make $170.

medicine is given in an amount proportional to a patient's body weight. Suppose a patient weighing 119 pounds requires 136 milligrams of medicine.
What is the weight of a patient who requires 200 milligrams of medicine?
Answer:
weight of the patient = 175 pounds
Step-by-step explanation:
Patient body weight : medicine
119 : 136
What is the weight of a patient who requires 200 milligrams of medicine?
Let
Patient body weight = x
Patient body weight : medicine
x : 200
Equate both proportions
119 : 136 = x : 200
119 / 136 = x / 200
Cross product
119 * 200 = 136 * x
23,800 = 136x
x = 23,800 / 136
= 175
x = 175 pounds

City Bank offers a 4.75% simple
interest rate, while First National
offers 3.9%. If Tom wants to set
up a new account with $500. how
much more money will he earn in
Interest at City Bank over First
National after 12 years?
Answer:
He will earn $51 more
Step-by-step explanation:
Let us compare the amounts he will earn in both banks
Mathematically, simple interest is;
I = PRT/100
Where P represents principal, R represents rate and T represents time
For Citibank, we have
I = (500 * 4.75 * 12)/100 = $285
For National bank
I = (500 * 3.9 * 12)/100 = 234
The difference between the amount of money earned in both banks will be;
285-234 = 51

Select all of the statements that are true for the given parabola.
Answer:
A and B are true
Step-by-step explanation:
The minimum is the turning point on the graph and occurs at (1, - 2)
The x- intercepts are where the graph crosses the x- axis , that is at
x = - 1 and x = 3 or in coordinate form (- 1, 0 ) and (3, 0 )
The equation of the axis of symmetry is a vertical line passing through (1, - 2)
with equation x = 1
The true statements are A and B
Answer:
⇨ A and B choice
Step-by-step explanation:
⟺ Consider all choices.
⥱ Choice A is correct because It's upward Parabola ( a > 0) where there is only the minimum point/value. The minimum point is at (1,-2). The vertex for upward parabola can be called the minimum point.
⥱ Choice B is correct because the Parabola intercepts x-axis at (-1,0) and (3,0) from the graph.
⥱ Choice C is wrong because the Axis of Symmetry is supposed to be x-term/value for the Parabola. If it is the y-value/term then it would be Side Parabola.
⥱ Choice D is wrong because an upward Parabola doesn't have the maximum point. The only Parabola with maximum point is downward Parabola ( a < 0)

Two tailors, Valentina and Laura, sit down to do some embroidery. Valentina can embroider 2 shirts per hour, and Laura can get through 3 shirts per hour. In addition, the tailors had previously finished some shirts. Valentina has already completed 15 shirts, and Laura has completed 11 shirts. Valentina and Laura decide to take a break when they have finished the same total number of shirts. How many shirts, in total, will each tailor have finished? How long will that take?
Answer:
Valentina and Laura finished the same total number of shirts in [tex]4[/tex] hours.
Total number of shirts finished by Valentina [tex]=23[/tex]
Total number of shirts finished by Laura [tex]=23[/tex]
Step-by-step explanation:
Suppose that Valentina and Laura finished the same total number of shirts in [tex]t[/tex] hours.
Valentina can embroider 2 shirts per hour and Valentina has already completed 15 shirts.
Total number of shirts finished by Valentina [tex]=2t+15[/tex]
Laura can get through 3 shirts per hour and Laura has completed 11 shirts.
Total number of shirts finished by Laura [tex]=3t+11[/tex]
Therefore,
[tex]2t+15=3t+11\\3t-2t=15-11\\t=4[/tex]
So,
Valentina and Laura finished the same total number of shirts in [tex]4[/tex] hours.
Total number of shirts finished by Valentina [tex]=2(4)+15=8+15=23[/tex]
Total number of shirts finished by Laura [tex]=3(4)+11=12+11=23[/tex]

There are 130 people in a sport centre. 61 people use the gym.
68 people use the swimming pool.
60 people use the track.
25 people use the gym and the pool.
30 people use the pool and the track.
19 people use the gym and the track.
6 people use all three facilities.
Given that a randomly selected person uses the gym and the track, what is the probability they do not use the swimming pool?
Step-by-step explanation:
Number of people who uses the gym and the track, and also uses the pool = Number of people who use all 3 facilities = 6. (given)
Number of people who uses the gym and the track, and may or may not use the pool = 19. (given)
Therefore number of people who use the gym and track, but do not use the pool = 19 - 6 = 13.
Probability = (13/19) * 100% = 68.4%.
I know the answer is 30 percent but I need the work
Answer:
See work below.
Step-by-step explanation:
There are 20 total blocks. 6 of them are painted. We can divide 6 by 20 and multiply that number by 100 to find the percentage of painted blocks.
6/20 = 0.3
Now, we need to multiply by 100 to convert to a percentage.
0.3 x 100 = 30%
Answer:
30% work below
Step-by-step explanation:
There are 20 squares in total if 6 are painted you get the fraction.
[tex]\frac{6}{20} /\frac{2}{2} = \frac{3}{10}[/tex]
3/10 as a decimal is .3
.3 as a percent is 30% because you move the decimal to the right 2 times.

If m∠13=2x-3 and m∠15=71°, find the value of x.
Show work please
Here ∠13 & ∠15 are corresponding angles , so they are equal [ ∠13 = ∠15 ]
As per the question ,
⇒ 2x - 3 = 71°
⇒ 2x = 71 + 3
⇒ 2x = 74
⇒ x = 74 ÷ 2
⇒ x = 37
Hence , x = 37
