Mathematics
1 answer:
Marat540 [252]2 years ago
5 0

Answer:

b. 36 years

Step-by-step explanation:

Today

Nirmala = x years

Rahul = 3x years

In 13 years

Nirmala = 3x + 13 years

Rahul = 2(x+13) - 1

3x + 13 = 2(x+13) - 1

3x + 13 = 2x + 26 - 1

3x + 13 = 2x + 25

3x - 2x = 25 - 13

x = 12

Nirmala = x years

= 12 years

Rahul = 3x years

= 3(12)

= 36 years

The age of Rahul today is 36 years

maw [93]

Answer:

14/1.8 = x/4

Step-by-step explanation:

Using similar triangles,

height of man/length of man's shadow = height of tree/length of tree's shadow

1.8/4 = x/14

x/14 = 1.8/4

If we cross-multiply, we have

1.8 × 14 = x × 4

dividing both sides by 4 and 1.8,we have

14/4 = x/1.8

x/1.8 = 14/4

So, the two expressions we have are

x/14 = 1.8/4 and x/1.8 = 14/4.

So, the answer is 14/1.8 = x/4 since the product 1.8 × 14 = x × 4 cannot be expressed in the given ratio.

How does the job satisfaction score for weeks 5-8 compare to weeks 1-4?
MrRa [10]

The correct comparison for Weeks 5-8 is higher than Week 1-4, hence, the job satisfaction for Week 5-8 is 17% higher.

<u>Job Satisfaction Score</u> :

  • Week 1 = 3.50
  • Week 2 = 3.40
  • Week 3 = 3.30
  • Week 4 = 3.60
  • Week 5 = 4.20
  • Week 6 = 4.00
  • Week 7 = 4.10
  • Week 8 = 3.90

<u>Job Satisfaction for week 1 - 4</u> :

  • Week 1 + Week 2 + Week 3 + Week 4
  • (3.50 + 3.40 + 3.30 + 3.60) = 13.80

<u>Job Satisfaction for Week 5 - 8</u> :

  • Week 5 + Week 6 + Week 7 + Week 8
  • (4.20 + 4.00 + 4.10 + 3.90) = 16.20

<u>Difference</u><u> between the two categories</u> :

[(Week 5 - 8) - (Week 1-4)] / Week 1-4] × 100%

(16.20 - 13.80) / 13.80 × 100%

(2.4 / 13.80) × 100%

0.1739 × 100%

= 17.39%

Therefore, the job satisfaction for Week 5 - 8 is about 17% higher than Week 1 - 4
