Answer:
4 -9/20
Step-by-step explanation:
separate whole numbers and fractions: 9-5, 3/10 - 3/4
then you subtract the whole numbers: 4
after that (what i mostly use that is easy for me is cross multiplication/ Butterfly method)

..A teacher is buying T-shirts for her algebra class.
- Long-sleeve T-shirts (x) cost $16 each.
- Short-sleeve T-shirts (y) cost $10 each.
The teacher wants to buy at least 24 T-shirts, and she wants to spend no more than $300 in all. Which system of inequalities represents this situation?
Answer:
[tex]240\leq 10x+16y\leq 300[/tex]
Step-by-step explanation:
Let short-sleeve be x and long-sleeve be y
So, the least amount she could spend buying at least 24 shirts is $240 because the cheapest shirt is $10/shirt. The max amount is already given.
[tex]240\leq 10x+16y\leq 300[/tex]

Use the graph to determine the domain and range. Then state whether the relation is a function.
What is the domain of the function?
Answer:
[-2, 4]
Step-by-step explanation:
The domain of a function is the set of all x-values a relation could possibly take on to have an output. This is represented by in the graph by having the line correspond to the x-value. From the graph shown we can see that x-values from -2 to 4 have a line corresponding to them, and the dots are closed meaning it is inclusive. This would be written as: [-2, 4]

Rick deposits $3 into his bank account. The following week, he deposits 3 times that amount. Each week after that, he deposits 3 times the amount he did the previous week.
How much does he deposit in all during the first 3 weeks?
1. Write an exponential expression that represents Rick’s deposit in the second week. Explain how you identified the base and the exponent.
3x3=9
9x3=27
3+9+27=39
$39
Exponent: 3³
Explanation: because he deposited three times as much three times, which would make for a cubed answer.

Answer:
Step-by-step explanation:
1.) I'm trying to see if I got this answer right. If not, correct me.
Step-by-step explanation:
The constant of proportionality (or constant of variation), denoted by "k," represents the constant proportion or ratio that exists between two variables, y and x, such that y = kx.
The given problem asks for you to identify the constant of proportionality and what it represents in context of the problem.
In the equation, y = 4.75x:
y = total cost in dollars earned
x = number of bracelets
The constant of proportionality, k = 4.75, represents the increase in total cost earned for every x number of bracelets sold. In other words, the total increases by 4.75 for every bracelet sold.
Thus, since Liv made x = 2 bracelets, then her total cost will equal to $9.50 because:
y = 4.75x
y = 4.75(2)
y = 9.50

What is the slope of the line passing through the points A and B, as shown on the graph below?
A)-3
B) -1/3
C) 1/3
D) 3
Answer:
-1/3
Step-by-step explanation:
We can start by finding the coordinates of 2 points, A and B. A is (-3, 8) and B is (3, 6). Now, we can use [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex] to find the slope, and if you plug in those points you get (8 - 6)/(-3 - 3) = 2/(-6) = -1/3.

An inverted conical water tank with a height of 12 ft and a radius of 3 ft is drained through a hole in the vertex. If the water level drops at a rate of 1 ft/min, at what rate is water (in ft3/min) draining from the tank when the water depth is 8 ft
Answer:
dhdt≃0.283ft3s
Step-by-step explanation:
dhdt≃0.283ft3s
The draining from the tank when the water depth is 8 ft will be negative 1/π feet per minute.
What is differentiation?The rate of change of a function with respect to the variable is called differentiation. It can be increasing or decreasing.
An inverted conical water tank with a height of 12 ft and a radius of 3 ft is drained through a hole in the vertex. If the water level drops at a rate of 1 ft/min.
[tex]\rm \dfrac{dV}{dt} = -1 \ ft/min[/tex]
The volume of the cone is given as,
V = (1/3) πr²h
The relation between r and h is given as,
r / h = 3 / 12
r = h / 4
Then the volume is written as,
V = (1/3) π (h/4)² × h
V = (π / 48) h³
Differentiate the volume with respect to time. Then we have
(dV)/(dt) = (π/48) x 3h² x (dh / dt)
- 1 = (π/48) x 3(4)² (dh / dt)
- 1/π = dh / dt
The draining from the tank when the water depth is 8 ft will be negative 1/π feet per minute.

Answer:
18 cm²
Step-by-step explanation:
All sides of a rhombus are the same length (as shown by the markings), so one side is 1/4 of the perimeter:
(24 cm)/4 = 6 cm . . . . side length
As with all parallelograms, the area is the product of the side length and the height perpendicular to that side:
A = (6 cm)(3 cm) = 18 cm²
It has an area of 18 cm².

An item that originally cost $100 is decreased by 8%. The reduced price is then increased by 8%.
The resulting price is_
between $92 and $100
$92
$100
more than $100
Answer:
$99.36
Step-by-step explanation:
Hii!
So first, you need to find 8% of $100. You can do that by 100 x 0.08 which is $8. This means that the cost is reduced by $8 so 100 - 8 = $92
The reduced price is $92.
Then if we increase the reduced price by 8%, we will find the resulting price. Agani we find 8% of $92 which is 0.08 x 92 = 7.36. This means we have to increase the cost of $92 by this amount. $92 + 7.36 = $99.36
Hope this helps :)
Answer: 99.36
Step-by-step explanation:
because when you add 430 to 0 it makes 492/5 x 40 then x goes into m 4302 times there for its 99.36 USD.
