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

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

Answer:

y = -2

Step-by-step explanation:

y - 2 = -4

add 2 to both sides

y - 2 + 2 = -4 + 2

y = -2

Answer:y= -2

Step-by-step explanation:

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.

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.

Answer:

Height of the pine tree = 60 in.

Step-by-step explanation:

Since, triangle formed by the tip of the tree and tip of the shadow of the tree will be similar to each other,

By the property of similarity, corresponding sides of the similar triangles will be proportional.

[tex]\frac{x}{20}=\frac{36}{d}[/tex]

If d = 12 inches,

[tex]\frac{x}{20}=\frac{36}{12}[/tex]

x = [tex]\frac{20\times 36}{12}[/tex]

x = 60 in.

Therefore, height of the pine tree will be 60 in.

Answer:

Step-by-step explanation:

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.

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.

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]

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

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:

Answer:

Step-by-step explanation:

b would be 0

your slope is rise/run. up one and over three. up one and over three. so 1/3

write it as y=1/3x+0, or y=1/3x

Answer:

I think the 4th line plot would not be true

Step-by-step explanation:

We could calculate the range and median.

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.

Step-by-step explanation:

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.

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.

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.

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
