Answer:

11 hurdles

Step-by-step explanation:

First hurdle = 45 m from start

Last hurdle = 40 m from finish

Other hurdles = 35 m apart

Let h = number of hurdles 35 m apart

400 = 45 + 40 + 35h

400 = 85 + 35h

400 - 85 = 35h

315 = 35h

h = 315 / 35

h = 9

Total number of hurdles = First hurdle + Last hurdle + Other hurdles

= 1 + 1 + 9

= 11 hurdles

Total number of hurdles = 11

Total;

-295

Step-by-step explanation:

Here, we want to write the sum of negative integers in order of the turns given in the question

We have these orders as follows;

-120-90-85

The sum of these is;

-295

The solution is Option C , Option D

The value of the equation is 8k = 20

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

8k = 20   be equation (1)

8k x 3 = 20 x 3

Divide both sides of the equation by 3 , we get

8 k = 20

Therefore , the value of k = 20/8

8k + 10 = 20 + 10

On simplifying the equation , we get

Subtracting 10 on both sides of the equation , we get

8k = 20

Therefore , the value of k = 20/8

Hence , the equation is 8k = 20

Answer:

rise over run is 1/4

Step-by-step explanation:

Here, we want to calculate the ratio of the rise to the run

Mathematically, this is simply referring to the slope

To get the slope, we need to select any two points and then apply the slope formula

The two points selected are;

(8,-6) and (-4,-9)

The slope formula is;

m = (y2-y1)/(x2-x1) = (-9 -(-6))/(-4-8) = -3/-12 = 1/4

Answer:

[tex]\frac{1}{4}[/tex]

Step-by-step explanation:

In this question, we have to find the slope with the given coordinates.

To find our slope, we would use the slope formula: [tex]m = \frac{y2-y1}{x2-x1}[/tex]

Plug in your coordinates and solve:

[tex]m = \frac{18-12}{40-16}\\\\m=\frac{6}{24}[/tex]

Simplify the fraction:

[tex]m=\frac{1}{4}[/tex]

The slope would be [tex]\frac{1}{4}[/tex]

Answer:

[tex]m=\frac{4}{3}[/tex]

Step-by-step explanation:

Slope can be calculated using following formula

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

Here

[tex](x_1, y_1) = (2, 1) \ \ \ and \ \ \ (x_2, y_2) = (8, 9)[/tex]

Substituting values in formula

[tex]m=\frac{9-1}{8-2}\\m=\frac{8}{6}\\m=\frac{4}{3}[/tex]

Answer:

Mean: 93

Mode: 90,94

Median: 93

Step-by-step explanation:

Mean: 93

Mode: 90, 94

Median: 93

The average of the numbers is the mean. Calculating is simple: add up all the numbers, then divide by the total amount of numbers.

Given a set: 90,92,94,91,90,94,95,98.

Mean = [tex]\frac{sum of all the numbers}{how many numbers there are}[/tex]  

Mean = the sum of all the numbers/how many numbers there are

There are 8 numbers and their sum is 744

Therefore, their mean is 744/8 = 93

The number that appears the most frequently in the sequence, or the mode, is that number. In this instance, the top times are 94 and 90.

The Median is the middle number when you place the numbers in ascending order 90, 90, 91, 92, 94, 94, 95, 98.

The middle number is between 92 and 94. So your middle number can be found by (92 + 94) / 2 = 93

So your median is 93

Answer:

x = 82

Step-by-step explanation:

The bottom angle is the same as the angle next to x + 6

A straight angle is 180 degrees.

You add the given angles: (x + 6) + (x + 10) = 2x + 16

180 = 2x + 16

- 16           -16

164 = 2x

Pumpkins are good for more than just jack-o’-lanterns: you can decorate with them, carve them, eat them, or plant the seeds so you have free pumpkins next year. You can find pumpkins for sale at farmers markets, pumpkin patches, and national chain retailers like Costco, Kroger, and Walmart. Farmers markets and pumpkin patches tend to price their pumpkins by the pound, charging around $16 to $25 for large pumpkins. Chain stores charge a per-pumpkin price, which is usually around $3 for small, decorative pumpkins and $5 to $10 for carving pumpkins. Below, we list the various uses for pumpkins, the places that sell pumpkins, and the average pumpkin prices.
