Question: Tyler and Kiran each started running at a constant speed at the same time. Tyler ran 4,200 meters in 30 minutes and Kiran ran 6,300 meters in 1/2 hour. Eventually, Kiran ran 1 kilometer (1000 meters) more than Tyler. How much time did it take for this to happen?
(I'll give 12 points and I'll name you brainlist.

Answers

Answer:

14 and 2/7 minutes, or 100/7 minutes

Step-by-step explanation:

To begin with, supposed the rate at which Tyler and Kiran are running are variables T and K. We can come up with the equations

30T= 4,200 and

30K= 6,300.

Where 30 is the number of minutes, multiplied by the rate at which they are running to equal the total distance ran. We can isolate the variables by dividing both sides of both equations by 30, resulting in Tyler's speed of 140 meters per minute and Kiran's speed of 210 meters per minute.

We can then plug these values into a final equation where x is the amount of time taken for Kiran to run 1 km more than Tyler

We end up with this: 210x= 140x+1000

Solve first by subtracting 140x from 210x to get 70x, and then divide both sides by 70. This isolates x and you get a final answer of 14 2/7 minutes, or 100/7 minutes

And sorry I couldn't get this to you in the 5 minutes you needed, but I hope this at least helps you understand the concept :')

It will take 14 and 2/7 minutes, or 100/7 minutes, for this to happen.

What is the equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

To begin, consider Tyler and Kiran's running rates to be variables T and K. We can create the equations.

30T= 4,200 and

30K= 6,300.

Where 30 is the number of minutes multiplied by the speed of running to equal the total distance run. By dividing both sides of both equations by 30, we can isolate the variables, obtaining Tyler's speed of 140 meters per minute and Kiran's speed of 210 meters per minute.

We have to substitute the value into a final equation where x is the time it takes Kiran to run 1 km further than Tyler.

We end up with this: 210x= 140x+1000

To begin, remove 140x from 210x to get 70x, then divide both sides by 70. This isolates x, obtaining a final result of 14 2/7 minutes, or 100/7 minutes.

Thus, It will take 14 and 2/7 minutes, or 100/7 minutes, for this to happen.

Which of the following best shows the associative property of addition?
a.4 + 5 = 9
b.(4 + 5) + 2 = 4 + (5 + 2)
c.4 + 5 + 2 = 2 + 5 + 4

Answers

Answer:

The answer is C: 4 + 5 + 2 = 2 + 5 + 4

Step-by-step explanation:

This is an example of the associative property of addition because the associative property of addition is described as any equation, that despite in what order your shift your equation to, the answer will stay the same. And as C shows, 4 + 5 + 2 will be rearranged to 2 + 5 + 4 and would still get the same answer, which would be 11.

The associative property of addition is represented by (4 + 5) + 2 = 4 + (5 + 2). The correct option is B.

What is associative property?

Rearranging the parenthesis in an expression will not change the outcome since some binary operations in mathematics have associative features.

The associative property is shown by the expression (4 + 5) + 2 = 4 + (5 + 2).

Solving the right-hand side:-

(4 + 5) + 2 = 9 + 2

(4 + 5) + 2 = 11

Solving the left-hand side:-

4 + (5 + 2) = 4 + 7

4 + (5 + 2) = 11

Therefore, the associative property of addition is represented by (4 + 5) + 2 = 4 + (5 + 2). The correct option is B.

When dilating by a factor of n, you multiple both the x and y-coordinates by n, so -5*2 is -10 2*2 is 4, making the coordinate (-10, 4)

Answer:

Step-by-step explanation:

The area of shaded rectangle is 8/3 square units.

To find the area of shaded rectangle.

What is rectangle?

A rectangle is a type of quadrilateral that has its parallel sides equal to each other and all the four vertices are equal to 90 degrees.

Given that:

length=4 units

width= 1-unit

The rectangle is subdivided into 3 parts parallely.so 1 units is unshaded and rest are shaded.

Area of rectangle =length*width

Area of bigger rectangle =length*width

                                       =4*1 square units

                                       =4 square units

width is subdivided into 3 parts .

so, 1/3,1/3,1/3 are the width.

Area of un shaded rectangle=length*width

                                                 =4*1/3 square units

                                                  =4/3 square units

so, Area of bigger rectangle=Area of un-shaded rectangle+ Area of shaded rectangle

4 =4/3+Area of shaded rectangle

Area of shaded rectangle=4-4/3

Area of shaded rectangle=12-4/3

Area of shaded rectangle=8/3 square units

Therefore, the area of shaded rectangle=8/3 square units.

What is the cost of making one burrito?

Answers

Answer:

$4.27

Step-by-step explanation:

Answer:

The cost of making one burrito is $2.50

By selling 100 burritos the restaurant would have profits of $550

Step-by-step explanation:

Since the cost of meat is $1.50 and the cost of other ingredients is $1 you add both of these together to get the total cost of making a burrito which is $2.50

In order to calculate profits you subtract 2.5 from 8 (which is 5.5) because it takes $2.5 to make a burrito

To find the total profits of selling 100 burritos you do 5.5 x 100= 550
