Laura left Dunkin Donuts at 1 PM traveling 30 mph. Two hours later her friend Jen left the same Dunkin Donuts and started after her on the same route traveling 45 mph. At what time will Jen catch up to Laura?

Answers

Answer:

It took Jen 4 hours to catch up with Laura

Step-by-step explanation:

Gaining speed 45-30= 15 mph

Laura's head start 30×2=60 miles

Time for Jen to catch up 60÷15= 4 hours

In other words

30(t+2)= 45t

30t+60= 45t

60=45t-30t

60= 15t

t=4 hours

Ruth wants to buy a skateboard for $44. She has $100 in her account. She spent $11.36 to buy stationary. She also wants to buy some comic books for $3.72 each. What is the maximum number of comic books, n, that Ruth can buy so that she has enough money left to buy the skateboard? (1 point)

Answers

Given :

Ruth wants to buy a skateboard for $44.

She has $100 in her account. She spent $11.36 to buy stationary.

She also wants to buy some comic books for $3.72 each.

To Find :

The maximum number of comic books, n, that Ruth can buy so that she has enough money left to buy the skateboard.

Solution :

Money left after buying skateboard and stationary is :

Money left = $(100 - 11.36 - 44)

Money left = $44.64

Number of comic she can buy is :

[tex]n = \dfrac{44.64}{3.72}\\\\n = 12[/tex]

Therefore, she can buy a maximum of 12 books.

Hence, this is the required solution.

If f(x) = 3X + 10 and g(x) = 2x – 4, find (f- g)(x).

Answers

So (f-g)(x) is f(x)-g(x) so you have

(3x+10)-(2x-4)

Distribute the negative in to the 2x-4 to get

3x+10-2x+4

Then combing like terms you have

3x-2x+10+4

And then that gives you

x+14

So (f-g)(x)=x+14

describe a system of linear equations that has no solution?​

Answers

Answer:

If a consistent system has an infinite number of solutions, it is dependent . When you graph the equations, both equations represent the same line. If a system has no solution, it is said to be inconsistent . The graphs of the lines do not intersect, so the graphs are parallel and there is no solution.

Step-by-step explanation:

Hope this helps - Good luck ^w

we can conclude that the system of linear equations has no solution when the graphs of equations are parallel.

What is a linear system of equations?

A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.

The collection of one or more linear equations, such that each of those equations have same set of variables, are known as system of linear variables.  

If a consistent system has an infinite number of solutions, it is dependent. When we graph the equations, both equations represent the same line.If a system has no solution, it is said to be inconsistent . The graphs of the lines do not intersect, so the graphs are parallel and there is no solution.

Therefore, we can conclude that the system of linear equations has no solution when the graphs of equations are parallel.

a)

Write down the mode. 7

b)

Work out the median.

c)

Calculate the mean. add all and divide by 10

d)

What is the range? 7

Answer:

Mode: 7

Median: 6

Mean: 5.2

Range: 5

Step-by-step explanation:

For the mode you have to find which number is present the most times

For the median you have to find the middle number if the total sum of numbers is an odd number, and find the average of the two if it is an even number ,like i did here (7+5)/2=6

For the mean you have to add every number and then devide with the total number of the numbers given:

(3+7+2+4+7+5+7+1+8+8)/10=5.2

For the range you have to find the largest number and subtract the smallest number from it (8-3)=5

The authors of the Articles of Confederation wanted to provide a way for the states to work together. But they did not want to form a government to rule the states as Britain had. As a result, the central government under the Articles lacked any real power. Many state leaders thought the government was too weak. It could not do its job. They called a convention to revise the Articles. James Madison wrote the Virginia Plan, which Edmund Randolph presented. It called for representation in Congress based on population. Not everyone liked the plan because they thought it gave too much power to large states. William Paterson proposed a different idea, called the New Jersey Plan. It provided for equal representation for all states. These two plans became the center of debate.
