Two particles are projected simultaneously towards each other from opposite ends of a straight horizontal tube. One particle travels 97 cm in the 1st 2 seconds, 93 cm in next 2 seconds , 89 cm in another next 2 seconds, etc. The other particle travels 49 cm in the 1st 2 seconds, 47 cm in the next 2 seconds , 45 cm in another next 2 seconds, etc. Find how long it takes for the particles to meet and hence, determine the distances travelled by each particle.

Answers

Answer 1

This shows that it will take the particle 23 secs to meet.

The distance travelled by each particle is 50cm

If two particles are projected simultaneously towards each other from opposite ends of a straight horizontal tube,

The first particle distances are 97cm, 93cm, 89cm... every 2secs

This form an arithmetic sequence and the nth term is expressed as:

Tn = a  + (n - 1)d

a is the first term = 97

d is the common difference = 4

Substitute

Tn = 97+(n - 1)(4)

Tn = 97 + 4n -4

Tn  = 4n  + 93

Similarly for the distances 49 cm, 47 cm, 45cm .....

This also forms an arithmetic sequence and the nth term is expressed as:

Tn = a  + (n - 1)d

a is the first term = 49

d is the common difference = 2

Substitute

Tn = 49+(n - 1)(2)

Tn = 49 + 2n -2

Tn  = 2n  + 47

For the particles to meet, this means that 4n  + 93 = 2n + 47

4n - 2n = 47 - 93

2n = -46

n = -23

This shows that it will take the particle 23 secs to meet.

To get the distance travelled by each particle

Tn  = 4n  + 93

T2 = 4(2) + 93

T2 = 101

For the other sequence;

Tn  = 2n  + 47

T2  = 2(2)  + 47

T2 = 51

Taking the difference;

D = 101 - 51 = 50cm

Hence the distance travelled by each particle is 50cm

Clear Plumbing charges a flat fee of $28.50 for a repair trip and $38. 50 per hour for labor. What is the total cost of a repair job that takes 3.5 hours?

Answers

Answer:

163.25

Step-by-step explanation:

38.50x3.5= 134.75

134.75+28.50= 163.25

38.5 per hour which explains 38.5x3.5= 134.75

28.50 is a one time fee so you add that to the total of hours 134.75+ 28.50= 163.25 in total.

C.

locations unrelated

Answers

Answer:

A. reflection across the y-axiss

Step-by-step explanation:

Given:

The locations of the two points are (-4 , 8) and (-4 , -8).

To find:

The relation between two points.

From the given points (-4, 8) and (-4 , -8), it is clear that the y-coordinates are same but the sign of x-coordinates are opposite.

If a figure is reflected across the y-axis, then we change the sign of x-coordinate and the y-coordinates remain same, i.e.,

[tex](x,y)[/tex]→[tex](-x,y)[/tex]

For (-4,8)

[tex](-4,8)[/tex]→ [tex](-4,-8)[/tex]

So, it is reflection across the y-axis.

Therefore, the correct option is A.

if carl runs 4 laps in 18 minutes, how many laps can he run in 1 1/2 hours

Answers

Answer:

20 laps

Step-by-step explanation:

18 divide by 4 = 4.5

so 1 lap equals 4.5 minutes

and 1 and half hours is 90 minutes so 90 divide by 4.5 = 20 laps

He can run 20 laps.

90 minutes is 1 1/2 hours
We setup the equation to solve:

4/18=x/90

Solve for x by isolating and then cross multiply.

2/9=x/90

Cross multiply,

180=9x

Swap sides,

9x=180

Divide both sides by 9

X=20 :)
