BARNEY'S BICYCLE SHOP IS SELLING T-SHIRTS AT THE LOCAL HEALTH FAIR. THEY PLAN ON SELLING SHIRTS FOR $8 EACH. TO HAVE THE SHIRTS MADE, BARNEY'S BICYCLE SHOP PAYS THE SHIRT MAKER $3.50 PER SHIRT PLUS AN INITIAL FEE OF $63. HOW MANY SHIRTS MUST BARNEY'S BICYCLE SHOP SELL BEFORE THEY CAN MAKE A PROFIT?
A. 9 SHIRTS
B. 8 SHIRTS
C. 14 SHIRTS
D. 11 SHIRTS
Barney's Bicycle Shop must sell at least 14 shirts before they can make a profit. Among the given options, the correct answer is C. 14 shirts.
To determine the number of shirts Barney's Bicycle Shop must sell before making a profit, we need to consider the cost of producing the shirts and the revenue generated from selling them.
For each shirt sold, the shop earns $8 in revenue. However, they incur costs to have the shirts made. The shirt maker charges $3.50 per shirt and an initial fee of $63.
Let's calculate the total cost per shirt:
Cost per shirt = $3.50 + ($63 / number of shirts)
To break even or make a profit, the revenue from selling the shirts must exceed the cost per shirt.
Let's calculate the revenue per shirt:
Revenue per shirt = $8
Now we can set up the equation to find the number of shirts needed to break even or make a profit as inequality:
Revenue per shirt ≥ Cost per shirt
$8 ≥ $3.50 + ($63 / number of shirts)
To solve this inequality, we can subtract $3.50 from both sides:
$4.50 ≥ $63 / number of shirts
Multiplying both sides by the number of shirts:
$4.50 x number of shirts ≥ $63
Simplifying the equation:
Number of shirts ≥ $63 / $4.50
Number of shirts ≥ 14

What is another name for angle 2?
Angle 2 could refer to different things, such as an angular velocity, a direction angle, or a contact angle, depending on its context within a mathematical or physical scenario.
Explanation:In mathematical terms, angle 2 refers to a particular position or orientation, typically specified in degrees. For instance, if points 1 and 2 rotate through the same angle (AO), angle 2 might move through a greater arc length because it is farther from the center of rotation. This concept is related to the mathematical definition of angular velocity, defined as radians per unit time.
Alternatively, angle 2 could also refer to the direction angle, which is the angle measured counterclockwise from the positive direction on the x-axis to a vector. This term is often used when calculating vector components. In this context, a positive angle indicates a counterclockwise rotation, whereas a negative angle implies a clockwise rotation.
Finally, angle 2 might specify the contact angle, which is the angle between the tangent to the liquid surface and the surface itself. To figure out the precise name for angle 2 in your particular context, I would need further information about the specific scenario or diagram you're referring to.

AB and BC are tangent to circle D. Find x if AB = 2x + 9 and BC = 3x + 6. Find x.
Answer:
the value of X comes out to be equal to 3
Step-by-step explanation:
since AB and BC are tangent to the circle D
then the length of the tangent will be same
AB will be equal to BC
where,
AB = 2 x + 9
and
BC = 3 x + 6
2 x + 9 = 3 x + 6
3 x - 2 x = 9 - 6
x = 3
hence, the value of X comes out to be equal to 3

Step-by-step explanation:
You are given the mountain that has a vertical height of 200 yards, and the ski lift will rise at an angle of 40 degrees. You are asked to find how many yards will a tourist travel from the base of the mountain to its peak. You can solve this using trigonometric function. More importantly, imagine that the mountain has a 90 - degree vertical height so that when you connect the peak of the mountain down to its base and then connected to the ski, you can form a right triangle.
Use the sine function.
sine β = opposite side / hypotenuse side
the opposite side will be the height of the mountain and the hypotenuse side will be the distance of the ski from the bottom going to the peak of the mountain
sine 40° = 100 yards / hypotenuse side
hypotenuse side = 100 yards / sine 40°
hypotenuse side = 156 yards
An aquarium tank holds 169 gallons of water. How much is this in liters? Use the following conversion: 1 gallon is 3.8 liters.
To convert gallons to liters, you multiply the number of gallons by the conversion factor 3.8. Therefore, an aquarium tank holding 169 gallons contains 641.2 liters of water.
Explanation:The question is asking about converting gallons to liters. The process involves simple multiplication using the conversion rate.
Given that the volume of water in the aquarium tank is 169 gallons and that 1 gallon is equivalent to 3.8 liters, you can find the volume in liters by multiplying the number of gallons by the conversion rate. Therefore, 169 gallons * 3.8 liters/gallon equals 641.2 liters.
This means there are 641.2 liters of water in the aquarium tank.

Today Javier put a cabinet on layaway by making a down payment of $80 and agreeing to pay $24 a month starting next month for 36 months. When will Javier receive the cabinet ?
A. 1 month
B. Today
C in 24 months
D in 36 months
Answer:
Option D is the answer.
Step-by-step explanation:
A layaway is a system of paying a deposit to secure an item that is meant to be purchased later. In this purchasing method, a buyer places a deposit on an item to lay it away. He can pick the item later when he pays the balance. The balance can also be paid in smaller installments until the full amount is paid.
So, here Javier will be paying for 36 months, hence, he will get the cabinet after 36 months.

What is the inverse of f(x)=70x^3/4 ?
The inverse of the function [tex]f(x) = 70x^{(3/4)[/tex] is [tex]f^{(-1)}(x) = (x/70)^{(4/3)[/tex].
Explanation:The inverse of the function [tex]f(x) = 70x^{(3/4)}[/tex] can be found by interchanging the roles of x and y and solving for y. The goal is to isolate y on one side of the equation.
Step 1: Replace f(x) with y: [tex]y = 70x^{(3/4)}[/tex]
Step 2: Swap x and y: [tex]x = 70y^{(3/4)}[/tex]
Step 3: Solve for y: Divide both sides of the equation by 70 and raise both sides to the power of 4/3 to undo the exponent: [tex]y = (x/70)^{(4/3)}[/tex]
Therefore, the inverse of [tex]f(x) = 70x^{(3/4)}[/tex] is [tex]f^{(-1)}(x) = (x/70)^{(4/3)}[/tex].
In triangle abc, the measure of angle b is 29 degrees° more than three times the measure of angle
a. the measure of angle c is 61 degrees° more than the measure of angle
a. find the measure of each angle.
Answer:
∠a = x
∠b = 3x + 29
∠c = x + 61
x + 3x + 29 + x + 61 = 180
5x = 180 - 29 - 61
5x = 90
x = 90/5
x = 18° ← ∠a
∠b = 3x + 29 = 3*18 + 29 = 83°
∠c = x + 61 = 18 + 61 = 79°

Answer:
D. 125
Step-by-step explanation:
Ratio between students and teacher = 16:1 , 16/1 =2000 /x , x = 2000/16 = 125 teachers
The number of teachers in the school will be 125. The correct option is D.
What are ratios and proportions?A ratio is an ordered pair of numbers a and b, denoted by the symbol a / b, where b does not equal zero. A proportion is an equation that sets two ratios equal to each other. For example, if there is one boy and three girls, the ratio could be written as 1: 3.
Given that at a certain university the student-to-teacher ratio is 16:1. If there are 2,000 students enrolled.
The number of teachers will be calculated as,
16 / 1 = 2000 / t
t = 2000 / 16
t = 125 teachers
Therefore, the count of teachers in the school is 125.
