Ethan is deciding between two parking garages. Garage A charges an initial fee of $7
to park plus $4 per hour. Garage B charges an initial fee of $10 to park plus $3 per
hour. Let A represent the amount Garage A would charge if Ethan parks for t hours,
and let B represent the amount Garage B would charge if Ethan parks for t hours.
Write an equation for each situation, in terms of t, and determine the interval of
hours parked, t, for which Garage A is cheaper than Garage B.
A=
B =
Garage A is cheaper than Garage B when t
Answer:
A= 4t + 7
B= 3t+10
Garage A is cheaper than Garage B when t < 3 hours.
Step-by-step explanation:
Garage A charges $7 just to enter the garage even for t=0 hours, and will charge and additional $4 per hour parked. Therefore the amount Garage A would charge for t hours of parking is: A= 4t + 7
Garage B charges 10 just to enter the garage even for t=0 hours, and will charge and additional $3 per hour parked. Therefore the amount Garage B would charge for t hours of parking is: B= 3t+10
To find the number of hours, t, that would make the parking garages cost the same, set the two equations equal to each other and solve for t:
4t + 7 = 3t + 10
-3 -3
t + 7 = + 10
- 7 -7 t = 3
Since both equation values are equal when t=3, we know that the two garages would charge an equal amount when parking for 3 hours.
Since Garage A has less expensive initial fee ($7 vs. $10), Garage A will continue to be less expensive until it "catches up" to Garage B at t=3 hours
When t is less than 3 hours, Garage A is cheaper.
The equations representing the situation and when garage A is cheaper than B is required.
The required equations are
[tex]A=7+4t[/tex]
[tex]B=10+3t[/tex]
Garage A is cheaper when the time to be parked is less than 3 hours.
System of linear equations
The required equations are
[tex]A=7+4t[/tex]
[tex]B=10+3t[/tex]
where [tex]t[/tex] = number of hours.
The point where the price is same will be
[tex]7+4t=10+3t\\\Rightarrow t=\dfrac{10-7}{4-3}\\\Rightarrow t=3[/tex]
when [tex]t=2[/tex]
[tex]A=7+4\times 2=15[/tex]
[tex]B=10+3\times 2=16[/tex]
when [tex]t<3[/tex] then garage A is cheaper.
when [tex]t=4[/tex]
[tex]A=7+4\times 4=23[/tex]
[tex]B=10+3\times 4=22[/tex]
when [tex]t>3[/tex] then garage B is cheaper.

On the number line, the given numbers can be located at the following points:
0.5 is located at point D.-1/2 is located at point C.–1.4 is located at point B.2 is located at point F.Recall:
A number line represent integers, whereby, negative integers are located on the left, while positive integers are to our right.Thus:
0.5 is a positive number, it would lie between integers 0 and 1 to our right.
Therefore, 0.5 is located at point D.- 1/2 is a negative number, it would lie between integers 0 and -1 to our left.
Therefore, -1/2 is located at point C.–1.4 is a negative number, it would lie between integers -1 and -2 to our left.
Therefore, –1.4 is located at point B.2 is a positive number, it would be located at our right.
Therefore, 2 is located at point F.Learn more about number line on:

It is 7 kilometers from kerrys house to the mall. About what is that distance in miles?
Answer:
[tex]\huge\boxed{\approx 4.4 \ \text{miles}}[/tex]
Step-by-step explanation:
In order to convert kilometers to miles, we can use a formula, assuming [tex]m[/tex] is miles and [tex]k[/tex] is kilometers.
[tex]m = \frac{k}{1.609}[/tex].
Since we know the kilometer reading (7), we can divide this by 1.609 to get our total miles.

1000 students participated in a survey on a university campus about their TV watching habits. All
respondents said they watched TV at least at some point during the day. 27% stated that they only
watched television during prime time hours (8pm - 10pm.) and 61% stated that they spend prime time
hours in their dorm rooms.
Hi, you've asked an unclear question. However, I inferred you may want to know the actual number of students represented by the percentages of 27%, and 61%.
Explanation:
Finding percentage usually involves performing two operations; multiplication and division.
First, all (100%) of respondents said they watched TV at least at some point during the day.
Next, 27% of respondents stated that they only watched television during prime time hours, in which the actual number of students represented by the percentage is calculated by dividing 27 by 100 and multiplying by 1000 =
[tex]\frac{27}{100} * 1000 = 270[/tex].
Finally, we are told 61% of respondents stated that they spend prime time hours in their dorm rooms. The actual number of students represented by the percentage is calculated by dividing 61 by 100 and multiplying by 1000 =
[tex]\frac{61}{100} * 1000 = 610[/tex]

Estimate the median of the distribution of drinks.
Hint: Think about the 50th percentile.
Answer:
25 grams
Step-by-step explanation:
The relative cumulative frequency gives us an equivalent of the percentiles of the distribution.
Thus, [tex] 50^{the} [/tex] percentile is equivalent to a relative cumulative frequency of 0.5.
The median is roughly the 50th percentile, which is a cumulative frequency of 0.5.
From the graph, the grams of sugar on the x-axis that corresponds to a cumulative frequency of 0.5 on the y-axis, is 25 grams.
Therefore, the median is 25 grams.

(3, –5)
Answer:
(-3,5) ia the answer
Step-by-step explanation:
It is because when you reflect it across the x axis the first coordinate will be negative and the second number is positive since its in the second square of the graph, so it is more of a resonable guess.

Answer: #1 - A. 210m, #2 - B. 21,39
First, find the width by using the equation 2450 = 2x * x. Multiply the like terms, which results in 2450 = 2x^2. Now, divide both sides by 2, which is 1225 = x^2. The square root of 1225 is 35. Now, to find the perimeter, the equation should be P = 2(70+35). 40 + 35 = 105, and 105*2 = 210. Therefore, the perimeter is A. 210 mNumber 2 is asking what number added by x would result in a perfect square. The first numbers in each of the options for the question so see which one creates a perfect square after it is added to 1500.√ 1500 + 56 = 2 √ 389√ 1500 + 21 = 39√ 1500 + 38 = √ 1538√ 1500 + 39 = 9 √ 19 B. 21, 39 would be the correct answer because it is the only perfect square.PLSSS HELPPPPP!!!!Which expression results in a sum or difference of three and four forty eighths?

Joyce's dad packs her lunch and always packs a yogurt. Joyce knows that there are 5 yogurts in the refrigerator: one raspberry, two strawberry, one blueberry, and one vanilla. Her dad usually reaches into the refrigerator and randomly grabs a yogurt.
a. which flavor is she most likely to have in her lunch today?
b. What are her chances of finding a vanilla yogurt in her lunch bag?
Answer:
a. [tex]Strawberry[/tex]
b. [tex]Chances = \frac{1}{5}[/tex]
Step-by-step explanation:
Given
[tex]Raspberry = 1[/tex]
[tex]Strawberry = 2[/tex]
[tex]Blueberry = 1[/tex]
[tex]Vanilla = 1[/tex]
[tex]Total = 5[/tex]
Solving (a): Yogurt with highest chance
From the list of given items, the number of strawberry yogurt (2) is more than any other yogurt (1 each)
This implies, She's most likely to get a strawberry than any other type
Solving (b): Chances of finding Vanilla
The chances is the same as probability
And it is calculated as thus;
[tex]P(Vanilla) = \frac{n(Vanilla)}{Total}[/tex]
[tex]P(Vanilla) = \frac{1}{5}[/tex]
Hence;
The chances is [tex]\frac{1}{5}[/tex]
