A parking garage bases its prices on the number of hours that a vehicle parks in the garage.
The first two hours cost $2 per hour, between two hours and six hours cost $2 per hour, and all hours after that cost $1.

The first two hours cost $2 per hour, between two and four hours cost $1 per hour, and all hours after that cost $0.50.
c
The first two hours cost $4, between two hours and six hours cost $2 per hour, and all hours after that cost $1.
d
The first two hours cost $4, between two hours and six hours cost $1 per hour, and all hours after that cost $0.50.
Answer:
c The first two hours cost $4, between two hours and six hours cost $2 per hour, and all hours after that cost $1.
Step-by-step explanation:
You want an interpretation of the graph that is a constant 4 up to x=2, has a slope of 2 for 2 ≤ x < 6, and a slope of 1 for x ≥ 6. The vertical axis is labeled dollars, and the horizontal axis is labeled hours.
Graph interpretationThe constant value of y = 4 for x < 2 means the cost of parking is $4 for the first two hours.
The slope of 2 from x=2 to x=6 means the cost of parking is $2 per hour between 2 and 6 hours.
The slope of 2 for x ≥ 6 means the cost of parking is $1 per hour for more than 6 hours.
The description of c applies.
__
Additional comment
The slope, or "unit rate", is the ratio of "rise" to "run". It can be simpler to choose a "run" of 1 and look at the corresponding "rise".
From x=2 to x=3, the cost rises from $4 to $6, a rise of 2 for the run of 1. That is why we say the slope is 2, or the "unit rate" in dollars per hour is $2 per hour.
A horse eats 10 kg of hay each day. she is for equal sized meals each day how many grams are in each meal ?
Answer:
For the problem with the horse: 10,000 grams
For the problem with the hiker labeled 11: 2 feet
I hope these answers are of use to you!
Step-by-step explanation:
Okay, for the horse problem I understood that it was a horse eating exactly 10 kg per day. If she does, then you just convert 10 kilograms to grams. To do this, you multiply the amount of kilograms by 1,000, since that is how it works.
10 x 1,000 = 10,000 grams.
For the problem labeled 11 with the hiker, you divide 120 ft by 60 since there are 60 seconds in a minute.
120 divided by 60 = 2 feet

Maria is going to purchase cranberry juice and lemon-lime soda for a new fruit punch recipe. The recipe calls for 3.5 times as many bottles of lemon-lime soda as cranberry juice. If she has $17.40, what is the most bottles of cranberry juice she can buy if cranberry juice costs $3.80 per bottle and lemon-lime soda costs $1.40 per bottle?
Answer:
Maria can buy at most 2 bottles of cranberry juice and 7 lemon-lime soda bottles.
Step-by-step explanation:
Setting up the SolutionFor this problem, we can set up an algebraic expression to represent the price, and this will help us solve the problem.
So firstly, let's assign the number of cranberry juice bottles to the variable "C". We could technically represent this as the variable name "cranberry juice bottles", but "C" is a bit more easier to write when writing an algebraic expression while still making it easy to distinguish. Let's also assign the number of lemon-lime soda to the variable "L".
Now let's find a way to express the price of each. The price of buying a certain amount of items, can generally be expressed as: [tex](\text{items bought})*(\text{item price})[/tex], since you have to pay the item price for each item bought, also known as, multiplication.
Since we know that the price of a cranberry juice bottle is $3.80 then that means the total amount used towards cranberry juice can be expressed as: [tex]3.80C[/tex]. We're just multiplying the number of cranberry juice bottles times the price. Likewise, we can represent the total amount used towards lemon-lime soda as: [tex]1.40L[/tex]. The same logic is being applied here.
Now if we add both of these, we get the total amount that will be spent which is: [tex]3.80C + 1.40L = T[/tex], and in this case I just set it equal to "T" which just represents the total spent.
Now there's two more things to do. Generally we can't really solve two-variable equations and we want to express one variable in terms of the other, so that we can rewrite the equation as a one-variable equation.
There is one piece of information given that allows us to do this. "The recipe calls for 3.5 times as many bottles of lemon-lime soda as cranberry". So we can represent the numbers of lemon-lime soda bottles as 3.5 times the amount of cranberry juice bottles. We can express it as: [tex]L=3.5C[/tex]
So now let's plug this into the equation, instead of "L". This gives us: [tex]3.80C + 1.40(3.5C) = T[/tex]
let's multiply the 1.40 by the 3
[tex]3.80C + 4.9C= T[/tex]
now let's add up the values.
[tex]8.7C=T[/tex]
Now lastly, this represents the total amount that is going to be spent. Since Maria only has $17.40, we want this total to be less than or equal to 17.40 (assuming there is no sales tax, but this was never given). this gives us our final expression we will be using: [tex]8.7C\le 17.40[/tex]
Solving the ProblemFrom here solving the problem is actually pretty easy. Think of the inequality as a linear equation, we can still apply the same (for the most part) algebraic manipulations we apply to linear equations. We just divide both sides by 8.7 to isolate the C
[tex]\frac{8.7C}{8.7}\le\frac{17.40}{8.7}\\\\C\le 2[/tex]
So Maria can buy a maximum of 2 bottles of cranberry juice. From this we can actually determine the number of lemon-lime soda bottles.
So we know that:
[tex]C=2[/tex]
From this we can determine what L is, since remember the equation we set up earlier?
[tex]L = 3.5C[/tex]
Let's just plug C into the equation, and we get:
[tex]L=3.5(2)[/tex]
Multiply
[tex]L=7[/tex]
So Maria can buy at most 2 bottles of cranberry juice and 7 lemon-lime soda bottles.

Weight of each small box: 13.75 kilograms
What is a system of equations?
A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations or an equation system.
Given that, the weight of 3 large boxes and 5 small boxes is 116 kilograms.
The weight of 9 large boxes and 7 small boxes is 238 kilograms.
Let x be the weight (in kilograms) of each large box.
Then the weight of 3 large boxes is 3x kilograms.
Then the weight of 9 large boxes is 9x kilograms.
Let y be the weight (in kilograms) of each small box.
Then the weight of 5 large boxes is 5y kilograms.
Then the weight of 7 large boxes is 7y kilograms.
The weight of 3 large boxes and 5 small boxes is 3x + 5y kilograms.
The weight of 9 large boxes and 7 small boxes is 9x + 7y kilograms.

What is the Basic Proportionality Theorem?
The basic Proportionality Theorem (can be abbreviated as BPT) states that, if a line is parallel to a side of a triangle that intersects the other sides into two distinct points, then the line divides those sides in proportion.
In the given figure side TU is parallel to side LK
If JK = 64 and JU = -4 + 4x
then UK = JK - JU
= 64 - (-4 + 4x)
=68 - 4x
Similarly,if JL = 72 and JT = 27
then TL = JL - JT
= 72 - 27
= 45
Now by using the property of the basic proportionality theorem, we can write
[tex]\frac{JT}{TL} =\frac{JU}{UK}\\\\ \frac{27}{45} =\frac{-4+4x}{68 - 4x}\\\\\frac{3}{5} = \frac{-4+4x}{68 - 4x}\\\\3(68-4x) = 5(-4+4x)\\\\204 - 12x=-20+2x\\\\204+20=14x\\\\x=\frac{224}{14}\\\\x=16[/tex]

A plane flying horizontally at an altitude of 2 km and a speed of 600 km/h passes directly over a radar station. Find the rate (in km/h) at which the distance from the plane to the station is increasing when it is 3 km away from the station. (Round your answer to the nearest whole number.)
Answer:
When the plane is 2mi away from the radar station, its distance's increase rate is approximately 433mi/h.
Step-by-step explanation:
Sketch a right triangle with one leg going vertically a length of 3 miles above the station, and the other leg x going horizontally from the top of the first leg. Distance r from plane to station is related by r2 = x2 + 32. Differentiate: 2r dr/dt = 2x dx/dt, which rearranges to the desired dr/dt = x/r dx/dt. When r = 4, x2 = 42 - 9 and x = √7. So dr/dt = (√7 / 4) * 520 mph = 344 mph.

What is speed?Speed is the ratio of distance and time.
It shows how fast an object is moving at a given time.
We have,
The stopping distance d is directly proportional to the square of the speed v.
This can be written as,
d ∝ v²
Now,
Converting 40 miles into feet.
1 mile = 5280 feet
40 miles = 40 x 5280 feet
40 miles = 211200 feet
Now,
40 feet ∝ 211200 feet per
Now,
The stopping distance is 40 feet when the speed is 40 miles per hour
d = 40 and v = (40 x 5280) feet per hour
d = k v²
k = d/v²
k = 40/(40 x 5280)²
k = 1/(40 x 5280²)
The mathematical model that gives the stopping distance d in terms of speed v is
d = 1/(40 x 5280²) v²
The stopping distance when v is 59 miles per hour
v = (59 x 5280) feet per hour
d = 1/(40 x 5280²) x (59 x 5280)²

True or false If the sample size is at least 30, we use the z-critical value
Z-tests are closely related to t-tests, but t-tests are best performed when the data consists of a small sample size, i.e., less than 30. The given statement is true.
Does critical value depend on sample size?
The sample size and the crucial value that the researcher employed must be connected. The variations in critical values between the t-distribution and the normal-shaped sampling distribution, however, are minimal for sample sizes bigger than 30.
Z-tests and t-tests are closely related, but t-tests work best with small sample sizes of data, or those with fewer than 30 participants. Additionally, whereas z-tests assume that the standard deviation is known, t-tests assume that it is unknown.
You must use the t-distribution table when working problems when the population standard deviation (σ) is not known and the sample size is small (n<30). General Correct Rule: If σ is not known, then using t-distribution is correct.

Arc = (θ/2π) 2πr
The radius of the sector is 1 unit and the central angle is π/3. Then the measure of the arc length of the sector will be given as,
Arc = [(π/3)/2π] 2π(1)
Simplify the equation, then we have
Arc = [(π/3)/2π] 2π(1)
Arc = (1/6) × 2π
Arc = π/3
Arc = 1.047 units
The proportion of the circular segment length of the area will be 1.047 units. Then, at that point, the right choice is A.

[tex]x+\frac{8x}{x-7} =\frac{56}{x-7}[/tex]
The equation has two solutions, on is extraneous and x = 7, and the real solution is x = -8.
How to solve the equation?Here we have the following equation:
x + 8x/(x - 7) = 56/(x - 7)
This is the original equation, notice that if x = 7, we will have a zero on the denominators, and we can't divide by zero, thus, x can't be equal to 7.
Now let's multiply all the equation by (x - 7)
(x - 7)*x + 8x = 56
Now we have a quadratic equation:
x^2 - 7x + 8x - 56 = 0
x^2 + x - 65 = 0
Using the quadratic formula we will get the two solutions:
[tex]x = \frac{-1 \pm \sqrt{1^2 - 4*1*-56} }{2*1} \\\\x = \frac{-1 \pm15}{2*1}[/tex]
Then the two solutions are:
x = (-1 + 15)/2 = 7 (this one is an extraneous solution, we can discard this one)
x = (-1 - 15)/2 = -8
This is our solution.
