Answer: There is no proportional relationship in commission and sales.
Step-by-step explanation:
to show a proportional relationship between two variables x and y , we write them as:
y= mx, where m = proportionality constant.
Let y = commission, x= sales , m= commission percent
Till x= $5000 , commission percent = 10%
Beyond x= $5000 , commission percent = 20%
i.e. m is not constant, but as x increases y also increases.
Hence, there is no proportional relationship in commission and sales.
You deposit $300 in a savings account. The account earns 2.5% annual simple interest. What is the account balance after 2 years?
Answer:
15$ would be earned
Step-by-step explanation:
This is because 2.5% of 300 is 7.5 than multiply it by 2 and you get 15.

Write the equation of the line that passes through the given points. (2,9.5) and (0,0.5)
Answer:
[tex]y = \frac{9}{2}(x) + \frac{1}{2}[/tex]
Step-by-step explanation:
Linear equations can be written as
[tex]y = mx + b[/tex]
m is [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
b is the y intercept
[tex]\frac{9.5 - 0.5}{2-0}\\ =\frac{9}{2} \\y = \frac{9}{2}x+b\\\frac{1}{2}= \frac{9}{2}(0) + b\\ b = 1/2[/tex]
plug in to verify
[tex]9.5 = 9/2(x) + 1/2\\\\9.5 = 9/2(2) + 1/2\\9.5 = 9 + 1/2\\9.5 = 9.5[/tex]

Answer:
D. 112°
General Formulas and Concepts:
A line is always 180°.
Order of Operations: BPEMDAS
Step-by-step explanation:
Step 1: Set up equation
m∠ABD + m∠DBC = m∠ABC
(3x + 10) + (2x) = 180°
Step 2: Solve for x
Combine like terms: 5x + 10 = 180Subtract 10 on both sides: 5x = 170Divide 5 on both sides: x = 34Step 3: Find m∠ABD
m∠ABD = 3x + 10
Substitute: m∠ABD = 3(34) + 10Multiply: m∠ABD = 102 + 10Add: m∠ABD = 112°I need help with #6 & #7 !!
Answer:
6 is b, 7 is c
Step-by-step explanation:
Answer:
#6 wants you to find out what answer from the 4 expressions gives you the least or smallest number. For #7, you need to follow PEMDAS in order to get the right answer.
Step-by-step explanation:
#6, the answers you get are 8, -9, -3, and 9. You need to choose the smallest number. Negative numbers are smaller than positive numbers, so you can immediately eliminate 8 and 9. You have to be careful when comparing negative numbers because the larger negative number is actually smaller than the smaller negative number since it is further away from the zero. So, negative -9 would be smaller than -3 in this case.
#7, I would divide the -720/12 first. This results in -60. Then, divide the -60 by -10. This gives you an answer of positive 6.
ANSWERS:
#6 : B
#7 : C

a water balloon was thrown from the window. The height of the water balloon over time can be modeled by the function y=-16square2+160x+50
The maximum height of the water balloon : 450 m
Further explanationQuadratic function is a function that has the term x²
The quadratic function forms a parabolic curve
The general formula is
f (x) = ax² + bx + c
where a, b, and c are real numbers and a ≠ 0.
The parabolic curve can be opened up or down determined from the value of a. If a is positive, the parabolic curve opens up and has a minimum value. If a is negative, the parabolic curve opens down and has a maximum value
So the maximum is if a <0 and the minimum if a> 0.
The formula for finding the coordinates of the maximum and minimum points of the quadratic function is the same.
The maximum / minimum point of the quadratic function is
[tex]\rm -\dfrac{b}{2a},-\dfrac{D}{4a}[/tex]
Where
D = b²-4ac
The function h (t) = -16x²+160x+50
so the value of a <0, then it has a maximum value
Because we are looking for maximum height, then we find the value of the y coordinate, with the formula
[tex]\rm -\dfrac{D}{4a}[/tex]
Questions we might add :
What was the maximum height of the water balloon after it was thrown?
We can also use the first derivative of the above function to find the maximum value
[tex]\tt h'=0=-32x+160\\\\-32x=-160\\\\x=5[/tex]
input to function :
[tex]\tt h=-16x^2+160x+50\\\\h=-16(5^2)+160(5)+50\\\\h=-400+800+50=\boxed{\bold{450~m}}[/tex]

ran 2 kilometers in 15 minutes, and Jada ran 3 kilometers in 20 minutes. Both ran at a constant speed. In kilometers, how far did Jada run in 60 minutes ?
PLZZZZZ HELP ASAP
Answer:
They did not run at the same speed. Calculation of their speed shows that Jada was running at a higher speed.
Step-by-step explanation:
Let's first calculate the speed of each person using the units provided so that we do not complicate the question.
speed = distance covered/time taken
Andre's speed = 2 km/15 min = 0.133 km/min
Jada's speed = 3km/20 min = 0.15 km/min
Clearly we can see that Jada was running at a higher speed than Andre. The question says they were running at constant speed not equal speed. That just means each person maintained their speed, they did not get faster or slower.
Is(1, 6)a solution to the inequality y < 4x + 2?
Answer:
yes, (1,6) is a solution to the inequality y<4x+2.
Step-by-step explanation:
Looking at the equation we can see that the slope is 4 and the y intercept is 2.
Now we will use the slope that is comprised of the rise over the run which is [tex]\frac{rise}{run}[/tex]
The slope is 4 this means that [tex]\frac{rise}{run}[/tex] = [tex]\frac{4}{1}[/tex] and this shows us that the rise is 4 and the run is 1, so starting at (0,2) you go up 4 and over 1 so our next coordinate would be (1,6)
so the answer is yes, (1,6) is a solution to the inequality y<4x+2.

The Library of Congress in Washington D.C. Is considered the largest library in the world. They often receive boxes of books to be added to their collection. Since books can be quite heavy, they aren't shipped in big boxes. If, on average, each box contains about 8 books, how many books are received by the library in 6 boxes, 10 boxes, or n boxes? Use the space below to tell me how many books are received in: 6 boxes = 10 boxes = n boxes = (Hint: Write an equation!)
Answer: The number of books in 6 boxes = 48
The number of books in 10 boxes = 80
The number of books in n boxes = 8n
Step-by-step explanation:
Given : Each box has contains about 8 books.
Total books : (Number of books in each box) x (Numbers of boxes).
Then, the number of books in 6 boxes = 8 x 6 = 48
Similarly,
The number of books in 10 boxes = 8 x 10 = 80
The number of books in n boxes = 8n
Hence, The number of books in 6 boxes = 48
The number of books in 10 boxes = 80
The number of books in n boxes = 8n
A class ordered six 8-slice pizzas. Each student ate 1 1/2 slices and no pizza was left over. How many students were there?
Answer:
There are 32 students.
Step-by-step explanation:
If there are six 8-slice pizzas, that means that there is 48 slices total. If each student ate 1 1/2 slices, you can divide 48 and 1.5, and you will get 32. That is the number of students in the class. Hope this helps!
