Answer:
a. $22.2
b= 13.32/x=3/5
Step-by-step explanation:
13.32/x=3/5
13.32×5=66.6
66.6/3=22.2
x(present cost)=$22.2
Answer:
22.20$
3/5 * cost = 13.32
Step-by-step explanation:
3/5 * cost (total price) = 13.32 (we know that 3/5 of the price is 13.32)
to solve
5/3 to cancel out 3/5 and isolate the cost
5/3 * 13.32 = 22.20
Traci paid $11 to get into a carnival. Each game she played cost $3. Which function can be used to find t, the total amount of money Traci will spend after playing g games?
Answer: Either A or B because you have to add the amount you have to get the total amount she spent.
Step-by-step explanation:
The price of a DVD is $19 . This price is 12% lower than last week.
What was the price of the DVD last week?
Answer:
$21.28
Step-by-step explanation:
First, find 12% or 19 -- this is 2.28
Next, take the total (19) and add 2.28 to it.
$19+$2.28=$21.28
2(y+5)=3(y-8) what value makes y ture
Answer:
y=34
Step-by-step explanation:
2y+10=3y-24
2y+10-10=3y-24-10
2y=3y-34
-y=-34
-y -y
y=34
Answer:
i think it would be 34
Step-by-step explanation:
2(y+5) = 3(y-8)
2y + 10 = 3y - 24
-2y -2y
10 = 1y, or y -24
10 = y - 24
+24 +24
34 = y

It is not a function because it does not pass the vertical line test. You can not have the same x in a function.
Answer:
C
Step-by-step explanation:
If you properly perform the vertical line test, you can see that the points are on the same x, which means the graph is undefined and not a function.

The line plot would be flat.
The individual data would not be shown.
We would not be able to find the mean.
We could calculate the range and median.
Answer:
I think the 4th line plot would not be true
Step-by-step explanation:
We could calculate the range and median.
What is Line Plot?A line plot, also known as a dot plot, is a type of graph that displays the distribution of a set of data. It consists of a number line with dots or X's placed above each data value to represent how many times that value appears in the data set.
Using the stem-and-leaf plot in the diagram, below, write out each data points given, which are:
68, 70, 80, 86, 88, 88, 96, 96, 97, 97, 98, 98, 99, 100, 100, 100, 100, 100
The line plot for these data would have the following frequency for each data point:
68 - 1 dot
70 - 1 dot
80 - 1 dot
86 1 dot
88 - 2 dots
96 - 2 dots
97 - 2 dots
98 - 2 dots
99 - 1 dot
100 - 5 dots
The line plot is shown in the diagram below.
Range = 100 - 68 = 32
Median = 97
Therefore, We could calculate the range and median.

What is the length of a ramp with the highest point being 5 feet above the ground, and the base of the ramp being 12 feet horizontally? Find the length.
Answer:
5^2+12^2= c^2
25+144=c^2
169=c^2
find the square root of 169
the length is = 13 ft
Step-by-step explanation:
Answer:
13
Step-by-step explanation:
In this concept, it forms a right triangle because it is 5 feet high, the base is 12 feet horizontally, and you need to find the hypotenuse (the longest side of the triangle/the slanted side). In this case, you can use the Pythagorean Theorem, which is [tex]a^{2}+b^{2}=c^{2}[/tex], where a and b are the lengths of the triangle, and c is the hypotenuse.
-We know a and b already, which are 5 and 12. So substitute a and b in the equation: [tex]5^{2}+12^{2}=c^{2}[/tex]
-Then, simplify to get: [tex]25+144=c^{2}[/tex]
-Add the 25 and 144 to then get: [tex]169=c^{2}[/tex]
-Find the square root of both sides to only get c left (the hypotenuse): [tex]\sqrt{169}=\sqrt{c^{2}}[/tex]
-Then you’ll get: [tex]\sqrt{169}=c[/tex], which simplifies to [tex]13=c[/tex]

While in France, Judy wants to sign up for a bike tour to see the countryside. She likes a tour that is 40 kilometers long, but she isn't sure how far that is. She decides to estimate the distance in miles. If Judy uses the fact that 1 kilometer is about 0.6 miles, what will her estimate be?
Answer:
24 miles
Step-by-step explanation:
In order to calculate Judy's estimation, we would simply have to multiply the actual distance in kilometers of the tour by the number of miles that Judy believes are in a single mile. This would give us Judy's estimation for how long the tour would be in miles.
40 km. * 0.6 miles = 24 miles
Finally, we can see that Judy's estimation would be that the tour is 24 miles long. Using Judy's believed conversion rate.

At the animal board house, the ratio of dogs to cats is 5:2. If there are 70 dogs in boarding, how many total animals are at the boarding house?
Answer:
98 total animals
Step-by-step explanation:
For every 5 dogs, there are 2 cats.
For every 10 dogs, there are 4 cats.
For every 15 dogs, there are 6 cats.
Hopefully you can see the pattern by looking at dogs and cats.
So for 70 dogs, 70 / 5 = 14
So you multiply the amount of dogs by 14 to get 70, but you also have to do the same with cats.
2 cats * 14 = 28 cats.
70 dogs + 28 cats = 98 total animals.
A city had a population of 2,425 and was growing by 27 residents per year. City B had a population of 1,813 and was growing by 63 residents per year. If this continues, how many years will it take for them to be the same?
Answer:
17 years
Step-by-step explanation:
In order to calculate this, we need to create an equality equation. In this scenario, we have the fixed values which are the total population and the rate of growth, and we also have one variable which is the number of years. We can use these values to create the following equation.
2,425 + 27x = 1,813 + 63x
Now that we have the equation we can solve for x to calculate how many years it will take for them to be the same population.
2,425 + 27x = 1,813 + 63x ... subtract 1,813 and 27x from both sides
612 = 36x ... divide both sides by 36
17 = x
Finally, we can see that both populations will be the same after 17 years.

determine the slope and the y-intercept
Answer:
B m = 1/2 y-int = -1
Step-by-step explanation:
at x = 0, y=-1 so that is the y-intercept
to find the slope, use the slope formula m=(y2-y1)/(x2-x1)
m=(0--1)/(2-0)
m=1/2
What is the center and radius of the circle with the given equation? [tex]x^2+y^2+2x+8y=8[/tex]
Answer:
(- 1, - 4 ) and r = 5
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
To obtain this form from the given equation use the method of completing the square.
Given
x² + y² + 2x + 8y = 8 ( rearrange by collecting x and y terms )
x² + 2x + y² + 8y = 8
To complete the square
add ( half the coefficients of the x/ y terms )² to both sides
x² + 2(1)x + 1 + y² + 2(4)x + 16 = 8 + 1 + 16
(x + 1)² + (y + 4)² = 25 ← in standard form
with centre (h, k ) = (- 1, - 4 ) and r = [tex]\sqrt{25}[/tex] = 5

Answer:
C. 4 and 5
Step-by-step explanation:
24 / 5 = 4.8
Option A is false since 4.8 is greater than both numbers.
Option B is also false because 4.8 is greater than both numbers.
Option C is true because 4 is less than 4.8 and 5 is greater than 4.8, making 4.8 lying between those numbers.

Shelby's family has a cell phone data plan that provides each family member with 5 gigabytes of data. Which ratios correctly relate the number of family members to the number of gigabytes of data?
Complete question is;
Shelby's family has a cell phone data plan that provides each family member with 5 gigabytes of data. Which ratios correctly relate to the number of family members to the number of gigabytes of data? Select all that apply
A) 1 to 10
B) 2 to 5
C) 2 to 10
D) 3 to 15
Answer:
Option C & D are correct.
Step-by-step explanation:
We are told that there is a cell phone data plan that provides each family member with 5 gigabytes of data.
This means that 1 family member gets 5 gigabytes of data.
Thus, ratio of family members to gigabytes of data will be at least;
1 : 5
In option A, we have ratio 1 to 10. This is wrong because it means 1 family member gets 10 gigabytes which doesn't follow with the 5 gigabytes provided.
In option B, we have ratio 2 to 5. This is wrong because it means 2 family members are sharing 5 gigabytes whereas the question says each family member gets 5 gigabytes.
In option C, we have ratio 2 to 10. This is correct because it means 2 family members share 10 gigabytes equally which means each has 10/2 = 5 gigabytes.
In option D, we have ratio 3 to 15. This is correct because it means 3 family members share 15 gigabytes equally which means each has 15/3 = 5 gigabytes.

A magician charges parties a $30 fee to cover travel and miscellaneous expenses plus $19.99 per hour. Write an equation to represent the relationship between x, the number of hours, and y, the total charge for the magician.
Answer:
y = 19.99x + 30
Step-by-step explanation:
y = 19.99x + 30
The x represents the number of hours, and because it costs 19.99 per hour, the coefficient before the x will be 19.99. The y-intercept is the fee because it doesn't change with the x.
