javeria left home at 7:10, she walked for 15 mins to the station and walked for 10 mins for a train. she then travelled by train for 45 mins.
at what time did javeria get off the train?
a) 8:25
b) 8:20
c) 8:15
d) 8:10

Answers

Answer: Its B 8:20

Step-by-step explanation:

U get this by adding the 15 minutes to the 7:10 and then u get 7:25 then you add the 10 and u get 7:35 then you add the 45 and you get 8:20

The time at which Javeria gets off the train is 8:20 thus option (b) is correct.

What are work and time?

Work is the completion of any task for example if you have done your homework in 5 hours then you have done 5 hours.

Another example of work is that if you have done your food by 1 hour it means your work duration is 1 hour so work is basically the time duration of any task which you have done.

As per the given,

Javeria left home at 7:10.

Add 15 + 10 + 45 = 70 minutes.

70 minutes = 1 hour + 10 minutes or 1:10

Add into 7:10 as

7 + 1:10 + 10

8:20

Hence "The time at which Javeria gets off the train is 8:20".

1. Write a quadratic equation for the parabola that passes through the
point (2, -3) with roots (-6, 0) and (4,0).

Answers

The quadratic equation with the given conditions is:

[tex]f(x) = \frac{3}{16}(x^2 + 2x - 24)[/tex]

The standard form of a quadratic equation with roots [tex](x_1,0)[/tex] and [tex](x_2,0)[/tex] is given by:

[tex]f(x) = a(x - x_1)(x - x_2)[/tex]

In which a is the leading coefficient.

In this problem, the roots are [tex]x_1 = -6, x_2 = 4[/tex], thus:

[tex]f(x) = a(x - (-6))(x - 4)[/tex]

[tex]f(x) = a(x + 6)(x - 4)[/tex]

[tex]f(x) = a(x^2 + 2x - 24)[/tex]

It passes through point (2,-3), which means that when [tex]x = 2, f(x) = -3[/tex], and this is used to find a.

[tex]a(2^2 + (2)(2) - 24) = -3[/tex]

[tex]-16a = -3[/tex]

[tex]a = \frac{3}{16}[/tex]

Thus, the equation is:

[tex]f(x) = \frac{3}{16}(x^2 + 2x - 24)[/tex]

The ordinate of a point is twice its abscissa . If its distance from the point (4,3) is √10 units ,then the coordinates of the point are ?

Answers

Answer:

(1 , 2) and  (3 , 6)

Step-by-step explanation:

the point P : (x , y) -> (x , 2x)    ... ordinate of P point is twice its abscissa, y = 2x

√10 = √(x-4)² + (2x-3)²

5x² - 20x + 25 = 10

x² - 4x + 3 = 0

(x-1)(x-3) = 0

x = 1    or    x = 3

y = 2    or   y = 6

Maria added 45,273 and 35,687 and got a sum of 70,960 is Maria’s answer reasonable? Explain.

Answers

Answer: No

Step-by-step explanation: Tell Maria to do the problem again.

If Maria added 45,273 and 35,687 and got a sum of 70,960 : Yes, Maria's answer is reasonable.

What is sum?

When we add 45,273 and 35,687 we have:

45,273 + 35,687 = 80,960

Maria's response, however, is 70,960, which is 10,000 below the accurate total. This indicates that Maria most likely added incorrectly.

The rationality of the response is demonstrated by the fact that Maria's answer is considerably less than the right answer. This 10,000-difference discrepancy is not a trivial error and suggests that an addition error most likely occurred.
