Find the slope between the two points:(10,6) and (20,20)

Mathematics

Zina [86]4 years ago

Hi there! The answer is 1.4

The slope of a line is the change of y-coordinates divided by the change of x-coordinates. Therefore, the slope of this line is
\frac{20 - 6}{20 - 10}  =  \frac{14}{10}  = 1.4

Solve for v. Show your work<br> 10 - (3v - 1) = 5(9 - v)
Whitepunk [10]

Answer:

The value of v is -17.

Step-by-step explanation:

10-(3v-1)=5(9-v)

10-3v+1=45-v

11-3v=45-v

11-45=3v-v

-34=2v

-34÷2=v

-17=v

Question: Mai had $14.50. She spent $4.35 at the snack bar and $5.25 at the arcade. What is the exact amount of money Mai has left?

Answer: $4.90

Steps: Step 1: Find operation: The operation in this problem is subtraction because words such as "spent" means that she used money, meaning we subtract.

Step 2: Figure out order of numbers: Now that we know that the operation is subtraction, we need to know what numbers to subtract. The problem says that Mai had $14.50, which means that this is the total amount of money she had when she started. Spent means that Mai used money, so this means that we subtract like this: $14.50-$4.35-$5.25.

Step 3: Subtract: Now that we know what operation to use, and what order to use the numbers, we can finish the problem:

<h2>                   $14.90</h2><h2>            -      $  4.35</h2><h2>           -------------------</h2><h2>                    $10.15</h2><h2>              -    $  5.25</h2><h2>           --------------------</h2><h2>                      $4.90 </h2>

Question: Kristina rides her bicycle 384.25 miles over 29 weeks to and from her job. How many miles does she ride each week to and from her job if she rides the same amount each week?

Answer: 13.25

Steps: 1: Find operation: To solve this question, we need to find the operation. Words such as "same amount each week" mean that this is division.

Step 2: Figure out order of numbers: Now, we need to figure out what to divide by. We divide 384.25 by 29 because it say that she rides 384.25 miles over 29 weeks.

Step 3: Divide: Now, we will solve the equation: 384.25 divided by 29 is 13.25, so the answer is 13.25.

Hope this helps you!

P.s. Sorry I could not show how to divide 384.25 by 29.

The times of all 15 year olds who run a certain race are approximately normally distributed with a given mean Mu = 18 sec and st
Brrunno [24]

The percentage of runners having times less than 14.4 sec is 0.15%. Then the correct option is A.

<h3>What is normal a distribution?</h3>

It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.

The times of all 15-year-olds who run a certain race are approximately normally distributed with a given mean (μ) = 18 sec and standard deviation (σ) = 1.2 sec.

The runners have times less than 14.4 sec.

The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.

\rm z-score = \dfrac{X - \mu}{\sigma }\\\\z-score = \dfrac{14.4- 18}{1.2}\\\\z-score = -3

Then the Percentage will be

\rm P(X < 14.4) = P(z < -3) = 0.0013499 = 0.13499\ \% \approx 0.15\ \%

More about the normal distribution link is given below.

What is the volume of a cube, if the length of one side is 12 cm?
irinina [24]
The formula for the volume of a cube is length times width times height. Since the sides of a cube are all the same, it would be 12 cubed (12 x 12 x 12). The answer is 1,728 centimeters cubed.
