I think that each shelf will be 19 inches.  Because 137 divided by 7 is 19 with the remainder of 4.  Half of 4 is 2. Take 2 inches off of each end and that is the 4.  So each shelf is 19 inches.

Answer:

19 inches.

Step-by-step explanation:

We have been given that Michelle has a plank 137 inches long that she wants to cut into 7 shelves of equal length. The plank has jagged ends, so she will start by cutting 2 inches off each end.

Since she cute 2 inches from each end, so she will cut 2*2 inches or 4 inches from both ends.

The length of plank left after cutting off jagged ends would be 137-4=133.

Now, we will divide 133 by 7 to find length of each shelf.

\text{Length of each shelf}=\frac{133\text{ inches}}{7}

\text{Length of each shelf}=19\text{ inches}

Therefore, the length of each shelf would be 19 inches.

It takes three hours for a boat to go 18 miles downstream, and nine hours to return. What is the rate of the boat in calm water
vampirchik [111]

Step-by-step explanation:

Distance = rate × time

If B is the rate of the boat, and C is the rate of the current, then we can write two equations:

18 = (B + C) × 3

18 = (B − C) × 9

Simplifying the equations:

6 = B + C

2 = B − C

Add the equations together to eliminate C:

8 = 2B

B = 4

Plug into either equation to find C:

C = 2

The boat's rate is 4 mph, and the current's rate is 2 mph.

Answer:

1) 1/10

2) 1/2

3) 1/5

Step-by-step explanation:

1)

1 favorable outcome and 10 total outcomes.

P(3) = \frac{1}{10}

2)

5 favorable outcomes and 10 total outcomes

P(even) = \frac{5}{10} = \frac{1}{2}

3)

2 favorable outcomes and 10 total outcomes

P(multiples\ of\ 5) = \frac{2}{10} = \frac{1}{5}

Y=0.2(4)x is it exponential growth or decay
Dmitry [639]

Answer:

growth

Step-by-step explanation:

This is of the form

y = ab^x  where a is the initial value and b is either growth or decay

if b > 1 then it is growth

b <1 it is decay

a = .2

b = 4

Since b>1 it is growth
