Answer:

\frac{45}{98}

Step-by-step explanation:

We have -\frac{3}{7} /(-1 \frac{1}{14} )

The first thing that we can do is to remove the mixed number

-\frac{3}{7} /(-\frac{15}{14} )

When you divide by a fraction, you can instead multiply by the reciprocal, which is that same fraction flipped upside down.

-\frac{3}{7} *(-\frac{15}{14} )

Now, we can multiply across the top and the bottom

\frac{45}{98}

The number of hours required to do a job varies inversely as the number of people working. It takes 8 hours for 4 people to pain
dezoksy [38]

Answer: it will take 5 people 6.4 hours to do the work.

Step-by-step explanation:

The number of hours required to do a job varies inversely as the number of people working. Let h represent the number of hours required to do the job. Let p represent the number of people working. Therefore,

h is inversely proportional to p

Introducing a constant of variation, k, it means that

h = k/p

It takes 8 hours for 4 people to paint the inside of a house. Therefore

8 = k/4

k = 8×4 = 32

The formula becomes

h = 32/p

To determine how many hours it will take 5 people to do the work, we will substitute p = 5 into the formula. It becomes

h = 32/5 = 6.4 hours

What is 3x²+5x+25 when x equals 3
Ksivusya [100]

Answer: 67

Step-by-step explanation:

3x^2 + 5x + 25

x = 3

3(3)^2 + 5(3) + 25

3^2 = 9

3(9) + 5(3) + 25

3 * 9 = 27

27 + 5(3) + 25

5 * 3 = 15

27 + 15 + 25

27 + 15 = 42

42 + 25 = 67
