Kiki wants to rent a bounce house for her daughter's party. The cost, y, to rent a bounce house for a number of hours, x, is shown in the table. The initial set-up fee is included in the cost.
Answers
185 = 2(x) + y
X is the hours and y is the setup fee
315 = 4(x) + y
Now you solve the first
185 = 2x+y
185-y = 2x
(185-y)/2 = x
That means you can plug that value into the second equation where you see the x
315 = 4((185-y)/2) + y
315 = 370-2y + y
315 = 370 - y
-55 = - y
55 = y
So y is 55 (the setup fee)
Back to the original
185 = 2(x) + y
185 = 2(x) + 55
130 = 2x
65 = x
Now test it
575 = 8x + y
575 = 8(65) + 55
575 = 520 + 55
575 = 575
Answer:
The initial setup fee is $55.The hourly rate is $65.Step-by-step explanation:
First of all, we need to find the equation that models this situation.
Let's find the constant ratio of change using two pair of values from the given table.
[tex]m=\frac{575-185}{8-2}=\frac{390}{6}=65[/tex]
The ratio of change is 65.
In other words, the hourly rate is $65, that is, 65 dollars per hour.
Then, we use the point-slope form to find the equation
[tex]y-y_{1} =m(x-x_{1} )\\y-185=65(x-2)\\y=65x-130+185\\y=65x+55[/tex]
Where [tex]55[/tex] refers to the initial condition.
In other words, the initial setup fee is $55.

How do you solve for B?
Equation is T = hP + 2B.
Answers
Subtract hp from both sides.
t - hp = 2b
Divide 2 from both sides.
b = t - hp / 2
Hope this helps!
To solve for B in the given equation, subtract hP from both sides and then divide both sides by 2. This results in B = (T - hP) / 2.
Explanation:To solve for B in the equation T = hP + 2B, you need to isolate B. Here's a step-by-step process to do that:
Subtract hP from both sides of the equation to get: T - hP = 2B.Then divide both sides of the equation by 2 to isolate B. The equation becomes B = (T - hP)/2.So, the solution for B in the equation is B = (T - hP)/2.

Caroline has 4 green cards, 3 red cars, 3 orange cards, and 1 gold card. if she discards the gold card, what percent of her remaining cards are red?
Answers
so that is 30% are red
After discarding the gold card, Caroline has 10 cards left. Since 3 of these are red, the percentage of red cards is 30%.
Explanation:To find the percent of the remaining cards that are red after Caroline discards the gold card, we must first determine the total number of cards left. Caroline initially has 4 green cards, 3 red cards, 3 orange cards, and 1 gold card, totalling to 11 cards. If she discards the gold card, she is left with 10 cards.
Now, since there are 3 red cards out of the 10 remaining cards, to find the percentage of red cards, we perform the following calculation:
Divide the number of red cards by the total number of remaining cards: 3 red cards / 10 remaining cards = 0.3.Convert the decimal to a percentage by multiplying by 100: 0.3 \(\times\) 100 = 30%.Therefore, 30% of Caroline's remaining cards are red.

A business owner pays $1,200 per month in rent and a total of $120 per hour in employee salary for each hour the store is open. On average, the store brings in $200 in net sales per hour. Which equation can be solved to determine the break-even point if x represents the number of hours per month the store is open?
Answers
The break-even point can be determined by setting the net sales per hour equal to the total cost per hour. The equation to solve for the break-even point is $200x = $1,320x. By dividing both sides of the equation by $1,320, we can find the value of x, which represents the number of hours per month the store needs to be open to break even.
Explanation:To determine the break-even point, we need to find the number of hours per month the store needs to be open in order to cover all its costs. The total cost for each hour the store is open is the sum of the rent and the employee salary. So, the total cost per hour is $1,200 + $120 = $1,320. The break-even point is reached when the net sales per hour equals the total cost per hour:
Net sales per hour = Total cost per hour
In this case, the net sales per hour is $200, so we can set up the equation:
$200x = $1,320x
where x represents the number of hours per month the store is open. By dividing both sides of the equation by $1,320, we can solve for x:
$200 = $1,320x / $1,320
$200 / $1,320 = x
x = 0.1515...
So, the break-even point is approximately 0.1515... hours per month, or about 9.09 minutes per month.

Let us take hours worked as x and Amount paid as y.
In the given functions
y = 15.4x ...(1)
y = 15.2x ...(2)
y = 16.4x ...(3)
y = 14.9x....(4)
We need to check which satisfies the relationship between x and y.
If x=2 then we need to get 30.4
So let us put x=2 in equation 1.
y=15.4×2
=30.8
Which does not matches.
Now let us check with second function.
y=15.2×2
y=30.4
It matches.
So let us check for other values.
x=4
y=15.2×4
y=60.8
x=5
y=15.2×5=76
if x=8, y=15.2×8=121.6
Hence y = 15.2x is the equation which could represent Relationship A.

As to find out the perimeter, you need to add all sides of the triangle together:
(0.5x+9) + 3x + (-3.4-25)
then group the variables together:
(0.5x+3x-3.4) + (9-25)
0.1x - 16
Answer:
The correct option is 3.
Step-by-step explanation:
It is given that the length of sides of a triangle are 0.5x+9, 3x, and -3.4x-25.
Let a=0.5x+9, b=3x, and c=-3.4x-25.
Perimeter of a triangle is the sum of length of all three sides.
[tex]Perimeter=a+b+c[/tex]
Substitute a=0.5x+9, b=3x, and c=-3.4x-25 in the above equation.
[tex]Perimeter=(0.5x+9)+(3x)+(-3.4x-25)[/tex]
On simplification, we get
[tex]Perimeter=0.5x+9+3x-3.4x-25[/tex]
Combine like terms.
[tex]Perimeter=(0.5x+3x-3.4x)+(9-25)[/tex]
[tex]Perimeter=(0.1x)+(-16)[/tex]

At 9:00 am linda leave work on a trip, sets her cruise control at 60mph. At 9:30 am, Bruce notices she left her briefcase and gets on the free way driving 90mph. At what time will Bruce catch up with Linda?
Answers
9:30 + one hour equals 10:30 and 90 miles away
In conclusion they will meet at 10:30
Bruce will catch up with Linda at 9:48 am.
Explanation:To find the time at which Bruce catches up with Linda, we need to determine the time it takes for Bruce to cover the same distance that Linda has already covered.
Since Linda starts her trip at 9:00 am and Bruce starts 30 minutes later at 9:30 am, Linda has a head start of 30 minutes or 0.5 hours.
In that 0.5 hours, Linda travels a distance of:
Distance traveled by Linda = Speed * Time
Distance traveled by Linda = 60 mph * 0.5 hours
Distance traveled by Linda = 30 miles
Now, Bruce needs to catch up with that distance of 30 miles. Let's find the time it takes for Bruce to cover that distance at his speed of 90 mph:
Time taken by Bruce = Distance / Speed
Time taken by Bruce = 30 miles / 90 mph
Time taken by Bruce = 0.33 hours
Since Bruce started at 9:30 am, he will catch up with Linda at:
Catch up time = Start time + Time taken by Bruce
Catch up time = 9:30 am + 0.33 hours
Catch up time = 9:48 am

Eddie is reading a novel for English lass. He has read 173 out of 480. About what percent of the book he has read ?
Answers
Final answer:
Eddie has read about 36% of the book for his English class, calculated by dividing the number of pages read by the total number of pages and then multiplying by 100.
Explanation:
To determine what percent of the novel Eddie has read for his English class, you would use the formula for calculating percentage: Percentage = (Part / Total) × 100. In this case, the part is the number of pages Eddie has read (173 pages) and the total is the number of pages in the novel (480 pages).
Now, let's calculate the percentage:
Percentage = (173 / 480) × 100
First, divide 173 by 480, which gives approximately 0.3604. Then, multiply this result by 100 to convert it into a percentage.
Percentage = 0.3604 × 100 => 36.04%
Therefore, Eddie has read about 36% of the book for his English class.

If a photo measuring 4 inches by 6 inches is placed in a photo frame that is 2 inches wide all around, what percent of the framed photo is the photo itself?
Answers
Answer:
Percentage of the photo = 50%
Step-by-step explanation:
Given that the measurement of the photo is 4 inches by 6 inches and the measurement of the photo frame is 2 inches wide all around, it simply implies that is measurement of the photo frame is (4inches + 2inches) by (6 inches + 2inches). I.e 6inches by 8inches
To find the percentage of the photo itself, let find the area of the photo and that of the frame
Area of photo = 4 inches x 6 inches = 24inches²
Area of photo = 6 inches x 8 inches = 48inches²
Percentage of the photo = area covered by the photo / area covered by the frame x100
Percentage of the photo = 24/48 * 100
Percentage of the photo = 50%

It is given that Trevor bakes 8 batches of biscuits, with 14 biscuits in each batch. He sets aside 4 biscuits from each batch for a bake sale and puts the rest in a container.
Total number of biscuits = Number of batches × Biscuit in each batch
Total number of biscuits = 8 × 14
