coach jenson bought 15 shirts for $180 for the basketball team. the unit rate for the shorts was 1.50 less than the unit rate for shirts. choach jenson bought the same number of shorts as shirts to complete each uniform. What was the total cost of the uniforms for the team? explain your answer
Answer:
$337.50
Step-by-step explanation:
To find the total cost of the uniforms, you will need to find the unit price of the shirts and the unit price of the shorts and then multiply each by the number of shirts and shorts, respectively.
The unit price of the shirts is the total cost divided by the number of shirts, or $180 / 15 shirts = 12/shirt.
The unit price of the shorts is
$12/shirt - $1.50/shirt = 10.5/shirt.
Since the coach bought the same number of shirts and shorts, the total number of shirts and shorts is 15 shirts + 15 shorts = 30 shirts and shorts.
The total cost of the shirts is $12/shirt * 15 shirts = $12*15 = 180.
The total cost of the shorts is $10.5/shirt * 15 shirts = 157.5
The total cost of the uniforms is the sum of the cost of the shirts and the cost of the shorts, or $180 + 157.5= 337.5.
Therefore, the total cost of the uniforms for the team is $337.5.

By using proportionality, it can be calculated that-
a) Constant of proportionality that relates the length of paver in the model and the actual length is k = [tex]\frac{4}{3}[/tex]
[tex]y = \frac{4}{3}x[/tex] is the required equation which relates the length of paver in the model and the actual length of the paver
b) Area of the rectangle = [tex]\frac{1}{3}[/tex] sq.feet
Constant of proportionality that relates the area of paver in the model and the actual area is k = [tex]\frac{9}{16}[/tex]
What is proportionality?
Suppose there are two quantities. Proportionality indicates that if there is a change in the value of one quantity, the value of other quantity also changes but maintaining a constant ratio
Proportionality can be direct or inverse
Direct proportion
Two quantities are said to be in direct proportion if on increasing the value of one quantity, the value of other quantity also increases and vice versa.
For example cost of a commodity and quantity of a commodity are in direct proportion
Inverse proportion
Two quantities are said to be in inverse proportion if on increasing the value of one quantity, the value of other quantity decreases and vice versa.
For example Number of men and number of days taken by those men to complete a job.
Length of paver in the model = [tex]\frac{2}{3}[/tex] ft
Actual length of paver = [tex]\frac{1}{2}[/tex] ft
Let the constant of proportionality be k
[tex]\frac{2}{3} = \frac{1}{2}k[/tex]
k = [tex]\frac{2}{3} \div \frac{1}{2}[/tex]
k = [tex]\frac{4}{3}[/tex]
Let y be the length of paver in the model and x is the actual length
[tex]y = \frac{4}{3}x[/tex] is the required equation which relates the length of paver in the model and the actual length of the paver
b) Area of the model = [tex]\frac{1}{2}\times \frac{3}{8} = \frac{3}{16}[/tex] sq. feet
Actual area = [tex]\frac{2}{3} \times \frac{1}{2} = \frac{1}{3}[/tex] sq.feet
Let the constant of proportionality be l

Answer:
MN = 50
Step-by-step explanation:
You want the length of the base segment MN in triangle MNO, where MN is marked 41+3x and parallel midsegment PQ is marked 49-8x.
MidsegmentThe midsegment is half the length of the parallel base segment. That means the base segment is double the length of the midsegment:
MN = 2·PQ
41 +3x = 2(49 -8x)
41 +3x = 98 -16x
19x = 57 . . . . . . . . add 16x-41
x = 3
MN = 41 +3x = 41 +3·3 = 50
The length of MN is 50 units.

When dividing 80 by 9, what is the remainder?
Answer:
8
Step-by-step explanation:
The number 80 is called the numerator or dividend, and the number 9 is called the denominator or divisor.
The quotient (integer division) of 80/9 equals 8; the remainder (“left over”) is 8.
80 is the dividend, and 9 is the divisor.
the expression x^3+ax^3+bx-3 where a and b are constants, has a factor of x-3 and leaves a remainder of 15 when divided by x+2. find the value of a and b
The values of a and b in the expression x³ + ax³ + bx - 3 are a = 1 and b = -17
How to determine the values of a and b?From the question, we have the following parameters that can be used in our computation:
x^3+ax^3+bx-3
Rewrite properly
So, we have
x³ + ax³ + bx - 3
The expression has a factor of x - 3
This means that
(3)³ + a(3)³ + b(3) - 3 = 0
So, we have
27 + 27a + 3b - 3 = 0
Evaluate the like terms
27a + 3b = -24
Divide by 3
9a + b = -8
The expression has a remainder of 15 when divided by x + 2
This means that
(-2)³ + a(-2)³ + b(-2) - 3 = 15
So, we have
-8 - 8a - 2b - 3 = 15
Evaluate the like terms
-8a - 2b = 26
Divide by -2
4a + b = -13
So, we have
9a + b = -8
4a + b = -13
Subtract the equations
5a = 5
Divide
a = 1
Recall that 4a + b = -13
So, we have
4(1) + b = -13
So, we have
b = -13 - 4
Evaluate
b = -17
Hence, the values are 1 and -17

Her commission rate is 7.44%.
What is commission rate?
The payment that is either a fixed amount or a percentage of a sale is the commission rate. When they make a sale, people in commission-based professions like insurance brokers, real estate agents, and car salespeople are compensated.
The parameters given are;
The amount Mary earns annually = $28,000
The amount Mary grossed during a week = $658.00
The amount Mary had sold during the week to make the amount grossed during the week = $1673.19
Given that Mary makes $28,000 per year
Therefore;
The amount Mary earns per week = Amount earned per year/52
The amount Mary earns per week = $28,000/52 = $538.46
The amount extra she made on commission = $658.00- $538.46= $119.54
The commission rate = Commission earned/(Amount of merchandise sold)×100

A forest ranger looking out from a ranger's station can see a forest fire at a 35 degree angle of depression. The ranger's position is 100 feet above the ground. How far is it from the ranger's station to the fire? Round your answer to the nearest tenth of a foot.
To find the distance from the ranger's station to the forest fire, we can use the tangent function and the information given in the problem. The tangent of an angle is defined as the ratio of the opposite side to the adjacent side in a right triangle. In this case, we can use the angle of depression to the forest fire, the height of the ranger's station above the ground, and the distance from the ranger's station to the forest fire to form a right triangle.
We can then use the tangent function to find the distance from the ranger's station to the forest fire as follows:
tan(35°) = opposite/adjacent
opposite = tan(35°) * adjacent
opposite = tan(35°) * 100 feet
opposite = 0.7392 * 100 feet
opposite = 73.92 feet
Therefore, the distance from the ranger's station to the forest fire is approximately 74 feet. To the nearest tenth of a foot, this is 73.9 feet.

what is meant by marginal tax?Marginal tax is the tax rate applied to an individual’s last dollar of income. It is the additional tax that must be paid on any additional income earned. In other words, it is the tax rate that applies to an individual’s income after all deductions. For example, if an individual’s income is $50,000 and the marginal tax rate is 25%, then the individual must pay an additional $12,500 in taxes on top of the $25,000 in taxes already paid on their $50,000 income.
Marginal tax rates are progressive, meaning that as an individual’s income increases, the marginal tax rate will increase as well. The marginal tax rate is important to understand because it helps individuals determine how much additional income they will need to earn in order to make up for the taxes they will have to pay on that income. It is also important to understand how marginal tax rates can affect tax planning strategies.
