Answer: 4 months

Look at it this way: 6 books in a group. How many groups are there? well this is multiplication. Just add 6 a bunch of times until you get 24. You will add 6+6+6+6. There are 4 6's. This means, there are 4 months, with 6 books each month.

Collins has a part-time job as a dog walker. The table below shows the amount of money Collins earned for different numbers of h
solmaris [256]

Answer:

Step-by-step explanation:

Part A:

For Dog walking, he earns $30 for 5 hours of work.

He earns $36 for 6 hours of work.

$30/5 hours = $6/hour

$36/6 hours = $6/hour

He earns $6/hour dog walking.

For 8 hours, he earns 8 hours * $6/hour = $48

To earn $66, he works 66/6 = 11 hours.

5 30

6 36

8 48

11 66

Part B:

He earns $7/hour for yard work, so multiply the number of hours by 7 to find the money he earns.

Table for yard work

Hours     Money

5             $35

6             $42

8             $56

Part C:

For 5 hours, he earns $35 for yard work and $30 as a dog walker.

$35 - $30 = $5

In the figure, AB is tangent to circle C. Find the length of DB.​
Andreyy89

Answer:

8.5

Step-by-step explanation:

First we need to get BC using the pythagoras theorem

BC² = AC² + AB²

BC² = 8² + 15²

BC² = 64+225

BC² = 289

BC = √289

BC = 17

DB = 1/2BC

DB = 1/2 * 17

DB = 8.5

Hence the length of DB is 8.5

I need help please if m&lt;MNR=43 and m&lt;MNP=84 find: m&lt;RNP​ subtract or add
Zielflug [23.3K]

Answer:

  41°

Step-by-step explanation:

The angle addition theorem tells you ...

  m∠MNR + m∠RNP = m∠MNP

Filling in the given values, you have ...

  43° + m∠RNP = 84°

Subtract 43° from both sides of the equation to find the angle of interest:

  m∠RNP = 84° - 43° = 41°

The measure of angle RNP is 41°.
