Answer:

B is the correct answer

Step-by-step explanation:

Let’s write the equation for Tim according to the question, that is t = 14h

Now for sheri, looking at the table, we can see that in two hours, he sells 14 tickets . This means that he sells at an average rate of 7 tickets per hour

Modeling his selling rate, with t being the number of tickets and h being the number of hours, we have;

t = 7h

Tim’s rate is t/h = 14

While sheri’s rate is t/h = 7

We can see that Tim’s rate is double Sheri’s rate

The rate of a linear function is simply the slope of the function.

The true statement is (b) the rate that Tim sells raffle tickets is double the rate that Sheri sells raffle tickets.

Tim's equation is given as:

[tex]t = 14h[/tex]

A proportional linear equation is represented as:

[tex]t = mh[/tex]

Where m represents the slope/rate.

This means that:

[tex]m = 14[/tex] --- Tim's rate

The slope of Sheri's table is calculated using:

[tex]m = \frac{y_2-y_1}{x_2 - x_1}[/tex]

So, we have:

[tex]m = \frac{28 -14}{12 -10}[/tex]

[tex]m = \frac{14}{2}[/tex]

[tex]m = 7[/tex] ---- Sheri's rate

By comparison:

[tex]14 = 7 \times 2[/tex]

This means that: Tim's rate doubles Sheri's rate.

Hence, the true statement is (b)

Answer:

45 degrees

Step-by-step explanation:

If KL = MN, and LM =3 and KN = 13, then HN = 13 - (13-3)/2 = 8

LN =  sqrt(HN^2 + LH^2) -->

LN = sqrt89 sqrt(8^2 + LH^2) -->

89 = 64 + LH ^2 -->

25 = LH^2 -->

LH = 5

Because HN  = 8, HK = 13 - 8 = 5

That makes both legs equal, which makes m∠LKN = 45 degrees

The angle  m∠LKN is equal to 45 degrees.

To understand more, check below explanation.

It is given that,

KL = MN, LM =3 , KN = 13 and LN [tex]=\sqrt{89}[/tex]

So that, HN = 13 - (13-3)/2 = 13 - 5 = 8

    [tex]LN = \sqrt{(HN)^{2}+(LH)^{2} }\\\\\sqrt{89} = \sqrt{(8)^{2}+(LH)^{2} }\\\\89=64+(LH)^{2} \\\\LH=\sqrt{25}=5[/tex]

Since,  HN  = 8. So that,  HK = 13 - 8 = 5

In a triangle, if two sides are equal. Then, opposite angle of both sides are also equal.

In triangle LKH,   LH = HK = 5 and [tex]\angle H=90[/tex]

So that,     m∠LKN = 90/2 = 45 degree.

Hence, the angle  m∠LKN is equal to 45 degrees.

Answer:

what is the radius given?

Step-by-step explanation:

With a height of 16 feet and a base radius of 5 feet, the volume of the cone is approximately 418.67 cubic feet, rounded to the nearest tenth.

To find the volume  V  of a cone, we use the formula:

[tex]\[ V = \frac{1}{3} \pi r^2 h \][/tex]

Where:

[tex]- \( \pi \)[/tex] is approximately 3.14

-  r is the radius of the base of the cone

-  h is the height of the cone

Given that the height h is 16 feet and the radius r is 5 feet, we substitute these values into the formula:

[tex]\[ V = \frac{1}{3} \times 3.14 \times (5)^2 \times 16 \]\[ V = \frac{1}{3} \times 3.14 \times 25 \times 16 \]\[ V = \frac{1}{3} \times 3.14 \times 400 \]\[ V = \frac{1256}{3} \]\[ V \approx 418.67 \][/tex]

So, the volume of the cone is approximately 418.67 cubic feet.

Complete question : Using 3.14 for pi, what is the volume, to the nearest tenth, of a cone that has a height of 16 feet and a base with radius of 5 feet.

The required value of x would be 8 to make LK Il OM for the shown triangle.

The angle bisector theorem is a geometric theorem that relates the lengths of the sides of a triangle to the lengths of the segments that bisect the opposite angles.

The line segment splits one side of a triangle into segments of length NO and NM, then the other two sides of the triangle are split into segments of length NK/KM and NL/LO respectively.

So, NK/KM = NL/LO

(x+2)/(x-3) = x/(x-4)

x² - 2x - 8 = x²- 3x

3x - 2x = 8

x = 8

The only options equivalent to 2:9 are B and C.

Step-by-step explanation:

A ratio is a comparison between two or more numbers.

When two ratios are equivalent, they describe the same relationship between numbers.

An equivalent ratio is to a number is usually the same ratio in which the numerator and denominator (first and second number) have been multiplied by a common multiple.

To find if two ratios are equivalent, we have to put them in their simplest forms and compare.

The ratio we are comparing other ratios with is 2:9

So, we will put all other ratios in their simplest form and see if it gives us 2:9

A. 9:2 - This is already in its simplest form and it is not equal to 2:9.

B. 18:81 - To put this in simplest form, we divide both numbers by 9:

18:81 = 2:9

Hence, this is an equivalent ratio to 2:9.

C. 12:54 - To put this in simplest form, we divide both numbers by 6:

12:54 = 2:9

Hence, this is an equivalent ratio to 2:9.

D. 18:4 - To put this in simplest form, we divide both numbers by 2:

18:4 = 9:2

This is not the same as 2:9.

E. 20:45 - To put this in simplest form, we divide both numbers by 5:

Answer:

26-3.50-8x=16.18

Step-by-step explanation:

To create an equation representing what she spent, we need to start with the money she had and end with the money she has left.

We know that she originally had $26, but when she was done shopping, she had $16.18. To get from $26 to $16.18, you have to subtract the cost. That gives you 26 - [ cost ] = 16.18

We know that she spent $3.50 on a notebook and  8 pens of an unknown cost. The unknown cost can be represented by x. To find the total cost, you must add the costs of what she bought together. That gives you 3.50 - 8x.

Plug the expression of the cost into the equation, and boom it's done.

26 - 3.50 - 8x = 16.18

To find the equation representing the money Amy spent on school supplies, we can use the given information and set up an equation. By solving the equation, we can find the cost of one pen and calculate the total amount of money Amy spent.

To represent the money Amy spent, we need to find the cost of 8 pens. Let the cost of one pen be x. The notebook cost $3.50, so the total money spent on the notebook and pens can be represented as:

$3.50 + 8x

According to the problem, Amy had $16.18 left after buying the notebook and pens. So we can set up the equation:

$26 - ($3.50 + 8x) = $16.18

Simplifying the equation, we have:

$26 - $3.50 - 8x = $16.18

$22.50 - 8x = $16.18

Subtracting $22.50 from both sides, we obtain:

-8x = -$6.32

Multiplying both sides by -1, we get:

8x = $6.32

Dividing by 8 on both sides, we have:

x = $0.79

Therefore, the cost of one pen is $0.79.

Cost of edging needed=?

Shape of garden = hexagonal= 6 sides and all sides are equal

The perimeter of a regular hexagon = 6×a

Where a = length of one of the sides , since the sides are equal.

Cost of edging = perimeter size (in feet) * cost per foot

Cost of edging = 6a * $2

Therefore, cost of edging = $12a

Where a = length of it's side in feet.

Answer: $144

Step-by-step explanation:

There are 12 feet on the hexagon so 12x2 is $24. there are also 6 sides on the hexagon so 6x24 is 144. (this is from a math textbook.)

The solution of given equation 6−by=19 is [tex]y = \frac{-13}{b}[/tex].

To find the value of y in the equation 6−by=19, subtract 6 from both sides, then divide by -b to isolate y as -13/b.

The variable y in the equation 6−by=19 can be solved for as follows:

6 -by =  19

Subtract 6 from both sides:

-by = 19 - 6

-by = 13

Divide by -b to isolate y is

[tex]y = \frac{13}{-b} = -\frac{13}{b}[/tex]

Therefore, y equals -13 divided by b.

The box hits the floor after 1 second.

In mathematics, expression is defined as the relationship of numbers, variables, and functions using mathematical signs such as addition, subtraction, multiplication, and division.

The function h = -16x²+ 16 gives the height h (in feet) of the box after x seconds. To find when the box hits the floor, we need to find the value of x when h = 0 (since the height of the box will be zero when it hits the floor).

So we can set the function equal to zero and solve for x:

-16x² + 16 = 0

Dividing both sides by -16, we get:

x² - 1 = 0

Factoring the left side, we get:

(x - 1)(x + 1) = 0

So the solutions are x = 1 and x = -1. However, we are only interested in the positive value of x since time cannot be negative.

To calculate the surface area of a regular pyramid, add the area of the base to the combined area of the triangular faces. The base area is known, but without the base perimeter or side lengths, the total surface area cannot be determined.

To find the surface area of a regular pyramid, we need to first know the surface area of the base, which is given as 84.3 cm². Then, we must calculate the surface area of the triangular faces. The student has provided the slant height (9 cm) and the base of the pyramid, but the length of the base side is not clear from the question. Typically, the formula for the surface area (SA) of a regular pyramid is SA = base area + 1/2 × perimeter of base × slant height. Since the area of the base is known, we only need the perimeter of the base to continue. If that perimeter or the number of sides and the length of each side were provided, we could use it to find the area of each triangle using the formula for the area of a triangle, which is 1/2 × base × height, and then multiply it by the number of triangles (sides) the pyramid has to get the total area of the triangular faces. This sum, along with the base area, would give us the total surface area of the pyramid. Without the individual side lengths or the perimeter, an exact surface area cannot be calculated.

Answer: Dakota was less than 51 inches last summer.

Step-by-step explanation: First of all let us represent Dakota's height last summer by letter x.

The height requirement for the roller coaster is given as 54 inches. This means Dakota must be 54 inches or higher in order to be allowed on the ride. However, Dakota is too short to ride. This can be represented mathematically as x < 54.

If However, last summer Dakota grew 3 inches taller, then we can also represent this mathematically as x + 3 < 54.

To solve for this;

x + 3 < 54

Subtract 3 from both sides of the inequality

x < 51. (That is x is less than 51)

Since Dakota's height has been represented by x, we can now interpret this inequality as;

Dakota was less than 51 inches tall last summer.

Answer:

A: The median weight for shelter A is greater than that for shelter B.

D: The data for shelter B are a symmetric data set.

E: The interquartile range of shelter A is greater than the interquartile range of shelter B.

Step-by-step explanation:

edg2020

From the box plots, we can conclude three things: (1) the median weight for Shelter A is greater than that for Shelter B, (2) neither Shelter A's nor Shelter B's data is symmetric, and (3) Shelter A has a greater interquartile range than Shelter B.

The box plots given provide valuable information about the weights of the dogs in two shelters. The line dividing the box represents the median weight of the dogs. For Shelter A, the median weight is 21 and for Shelter B, the median weight is 18. Therefore, the statement that the median weight for Shelter A is greater than that for Shelter B is correct.

Next, it's crucial to understand the concept of symmetry in the data set. If a data set is symmetric, the whiskers (that represent the variation or spread of the data) of the box plots would be roughly of equal lengths, indicating uniform spread around the median. Given the information, neither Shelter A nor Shelter B display symmetric whisker lengths, so the data for neither shelter A nor B is a symmetric data set.

Finally, the Interquartile Range (IQR) represents the range within which the central half of the weights lies — it is the difference between the third quartile (the right end of the box) and the first quartile (the left end of the box). For Shelter A, the IQR is 28 - 17 = 11, and for Shelter B, the IQR is 20 - 16 = 4. Therefore, the interquartile range of shelter A is indeed greater than the interquartile range of shelter B.
