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.

Answer:
Y=15x
Step-by-step explanation:
Like the x is 1,2,3,4 and the y is 15,30,45,60 etc.
So the formula is y=mx+b
m stands for slope
b is for y intercept. That means what is the y when x is 0.
So first slope. m=y2-y1/x2-x1 or rise/run. Rise as in the y axis and run as in the x axis.
So let’s use the first 2 points. (0,0) (1,15)
15-0/1-0= 15/1= 15
So m=15
For b, when x is zero, y is also zero. So you would just leave that part out. I mean I guess you can put a +0 but it’s unnecessary.
So y=15x
Ps. You can also try diff points for m. 30-15/2-1 = 15/1=1 ect. Even like 60-15/4-1= 45/3 = 15
plz help me and plz show work
Answers
Answer:
21. The slope is 50.
22. 0
23. y=50x
24. $2600
Step-by-step explanation:
21. The slope of the line is 50. Slope is defined as "rise over run". As the line increases, each segment moves up the y-axis by $50, and to the right on the x-axis 1 segment. (Work: 50 divided by 1)
22. The y-intercept is (0, 0), or simply 0. If you look at the graph you can see that the line crosses the y-axis at the origin. This makes the y-intercept equal to 0.
23. The slope tells you that the student makes $50 every week. The y-intercept is 0. Using the formula y=mx+b, an appropriate equation would be y=50x.
24. The equation found in problem 23 can me used to determine how much a student makes (y) after "x" weeks. Substitute 52 for x to solve for y. This becomes y=50(52). This can be simplified to y=2600. This means that after 52 weeks, the student will have made $2,600.

8.89 centimeters
Step-by-step explanation:
In order to convert 3.5 inches to centimeters, we must use dimensional analysis.
3.5 inches x [tex]\frac{2.54 cm}{1 in} = 8.89cm[/tex]
Simply multiple 2.54 centimeters by 2.5 inches to find how many centimeters are in 3.5 inches. After doing that you will see that 3.5 inches equals 8.89 centimeters.

Set theory is an area of mathematics that primarily deals with objects that are pertinent to mathematics as a whole, despite the fact that any form of an object can be gathered into a set.
Given that the universal set is U = {1, 2, 3, 4, 5}, and the set A is {1,5}. The value of the set A' will be calculated as,
U = {1, 2, 3, 4, 5
A = {1,5}
A' = {2,3,4}
Therefore, the value of the set A' for the set A{1,5} from the universal set will be A'{2,3,4}.

Which rational number represents the number of months that Callie has to pay off the bill? What does the sign on the number mean?
Part C
Write an expression to represent the net change to Callie’s account balance each month.
Part D
Simplify the expression in part C to find the net change to Callie’s account balance each month.
Part E
After paying the car service center in full, Callie realizes that she should start saving money each month for her future. She decides to invest the same monthly amount that she was paying the service center in a retirement fund. If she invests in the retirement fund for one year, what will the net change in her account balance be during that time
Part F
What is the sign of the net change in part E? Why does the sign make sense in this situation?
Answers
Part A The net change to Callie’s bank account is -$416.48. The negative sign indicates money leaving Callie’s account.
Part B Callie has 4 months to pay off the bill. The rational number is +4. The sign is positive because it represents a quantity of something, in this case, months.
Part C The amount of the bill, -$416.48, will be deducted from Callie’s account in equal amounts over 4 months. So, the expression representing the net change in her account balance each month is -416.48/4 .
Part D -416.48/4=104.12
Part E The monthly withdrawal from Callie’s account continues to be -$104.12. After 1 year (12 months), the net change to her account balance will be -$104.12 × 12 = -$1,249.44.

Let us mark the points R and S on line p, T and U on line q, A and B on line l and C and D on line m.
Suppose the lines p and q intersect the line l at K and L respectively and line m at N and M respectively.
Since, AB is a straight line and ray KN stands on it, then
∠NKL + ∠NKA = 180∘ (Angles in a linear pair)
⇒110∘ + a = 180∘
⇒a = 180∘ − 110∘ = 70∘
Since, line p || line q and line l is a transversal intersecting them at K and L, then
∠TLB = ∠NKA (Alternate exterior angles)
⇒b = a
⇒b = 70∘
Since, line p || line q and line m is a transversal intersecting them at N and M, then
∠CNK = ∠NML (Corresponding angles)
⇒c = 115∘
Since, CD is a straight line and ray ML stands on it, then
∠NML + ∠LMD = 180∘ (Angles in a linear pair)
⇒115∘ + d = 180∘
⇒d = 180∘ − 115∘ = 65∘
