Given:
Jamie receives 15% commission on magazine subscriptions.
One week her sales totaled $860.
To find:
Her commission.
Solution:
We have,
Total sales of one week = $860
Rate of commission = 15%
Now,
[tex]Commission=\dfrac{15}{100}\times 860[/tex]
[tex]Commission=\dfrac{15}{10}\times 86[/tex]
[tex]Commission=\dfrac{1290}{10}[/tex]
[tex]Commission=129[/tex]
Therefore, the amount of commission is $129.

Here are the weekly allowances for 10 Grade 7 students:
$9, $11, $13, $15, $20, $10, $12, $15, $10, $15
What is the mean allowance?
Mean allowance of the given students is equals to $13.
What is mean?
" Mean is defined as the ratio of the sum of all the given number to the total number of numbers. It is also known as average."
Formula used
Mean = [tex]\frac{Sum of all the given numbers}{Total number of numbers}[/tex]
According to the question,
Number of students = 10
Weekly allowances of each student
= $9, $11, $13, $15, $20, $10, $12, $15, $10, $15
Substitute the value in the formula of mean we get,
mean = [tex]\frac{9+11+12+13+20+2(10)+3(15)}{10}[/tex]
[tex]= \frac{130}{10}\\ \\= 13 dollars[/tex]
Hence, mean allowance of the given students is equals to $13.

Answer:
y = ²/₃x + 3Step-by-step explanation:
y=m₁x+b₁ ║ y=m₂x+b₂ ⇔ m₁ = m₂
{Two lines are parallel if their slopes are equal}
Changing to slope-intercept form:
2x - 3y = 9 {subtract 2x from both sides}
-3y = -2x + 9 {divide both sides by (-3)}
y = ²/₃x - 3 ⇒ m₁=²/₃ ⇒ m₂=²/₃
The line y=²/₃x+b passes through point (6, 7) so the equation:
7 = ²/₃×6 + b is true
7 = 4 + b
b = 3
Therefore equation in slope-intercept form:
y = ²/₃x + 3
The equation of the line passing through the point (6, 7) parallel to the line is y = 2/3x + 3
The equation in slope - intercept form :
2x - 3y = 9
-3y = 9 - 2x
Divide both sides by - 3
y = - 3 + 2/3x
Using the points (6, 7)
7 = c + 2/3(6)
7 = c + 12/3
7 = c + 4
c = 7 - 4 = 3
c = 3
The equation of the parallel line is thus :

The price of a can of green beans is raised from $0.50 to $0.60. What is the percent increase in the price of the can of green beans?
Answer:
20%
Step-by-step explanation:
Here, we want to calculate the percentage increase in the price of a can of green beans
Mathematically, we use the formula below;
(new price - old price)/old price * 100%
From the question;
old price = $0.50
new price = $0.60
So we have;
(0.6-0.5)/0.5 * 100%
= 0.1/0.5 * 100%
= 20%

A transaction is positive if there is a sale and negative when there is a return. Each time a customer uses credit card for a transaction, the credit company charges Isabel. The credit company charges 1.5% of each sale and a fee of 0.5 % for returns
Full question:
A transaction is positive if there is a sale and negative when there is a return. Each time a customer uses credit card for a transaction, the credit company charges Isabel. The credit company charges 1.5% of each sale and a fee of 0.5 % for returns
Let x represent the amount of a transaction and let f(x) represent the amount Isabel is charged for the transaction. Write a function that expresses f(x)
Answer:
f(x)= 0.015(x)
f(x)= 0.005(x)
Explanation:
If Isabel makes a sale, she has a positive transaction and therefore is charged 1.5%(which is 0.015) by the credit company for the transaction. If the product is returned, it is a negative transaction and the credit company charges 0.5%(which is 0.005) for the transaction. The functions for positive and negative transactions would be different as indicated in the answer since transactions( given by x) are different- positive and negative.

Help me please pass math
Answer:
Step-by-step explanation:
This question is a bit sloppy. In higher math courses it would not be permitted. I'll give you the general rule that applies to this question -- sort of.
If you have a triangle that hast angles of 100 50 and 30
The largest side will be opposite the 100 degree angle.
The smallest side will be opposite the 30 degree angle.
So for the question, you are intended to say that CD > AB because CD is opposite a 43 degree angle and AB is opposite a 40 degree angle.
So the answer is Since 43 > 40 then CD>AB

A boat is pulled in by means of a winch located on a dock 10 feet above the deck of the boat. Let the angle of elevation ø = 18 degrees. Find the length s of the rope.
9514 1404 393
Answer:
32.4 feet
Step-by-step explanation:
The applicable relationship between angle and triangle lengths is ...
Sin = Opposite/Hypotenuse
The dock height is the side of the triangle opposite the given angle. The desired length is the hypotenuse of the triangle, so we have ...
sin(18°) = (10 ft)/s
s = (10 ft)/sin(18°) = (10/0.30902) ft
s ≈ 32.4 ft
The length of the rope is about 32.4 feet.

Answer:
(-2, -4)
Step-by-step explanation:
Since both equations are equal to y, you can set them equal to each other:
[tex]\frac{3}{2}x-1=\frac{1}{2}x-3[/tex]
Next, solve for x:
[tex]\frac{3}{2}x-1=\frac{1}{2}x-3\\x-1=-3\\x=-2[/tex]
Finally, substitute the solution for x in one of the equations (or both) to find y:
[tex]y=\frac{3}{2}(-2)-1\\y=-3-1\\y=-4[/tex]
[tex]y=\frac{1}{2}(-2)-3\\y=-1-3\\y=-4[/tex]
Therefore, the solution to the system of equations is (-2, -4).

The cost of dinner is $300 and $10 per students.
To find:
The initial value and rate of change and their interpretation.
Find the cost function C where n is the number of students.
Solution:
The slope intercept form of a linear function is
[tex]f(x)=mx+b[/tex] ...(i)
where, m is rate of change and b is y-intercept or initial value.
We have,
[tex]P(d)=0.445d+14.7[/tex] ...(ii)
From (i) and (ii), we get
[tex]m=0.445,b=14.7[/tex]
The initial value is 14.7. It means, the pressure at sea level is 14.7 pounds psi.
Rate of change is 0.445. It means, the pressure is increasing by 0.445 pounds psi for every feet.
The cost of dinner is $300 and $10 per students.
Let C(n) be the total cost for dinner and n be the number of students.
Fixed cost = $300
Additional cost for 1 student = $10
Additional cost for n student = $10n
Now,
Total cost = Fixed cost + Additional cost
[tex]C(n)=300+10n[/tex]
Therefore, the required cost function is [tex]C(n)=300+10n[/tex].
