Riley needs 32 pirates for every 2 pirate ships he manages.
aleksandrvk [35]

#1 = 96

#2 = 162

There is 16 pirates per ship since there is 32 pirates in 2 ships. This means that you can multiply 16 by 6 and 16 by 12 to get your answers

PLEASE HELP ME Determine whether the graph represents a proportional relationship. A graph is shown. The x-axis is labeled from
suter [353]

Answer:

No, the graph does not represent a proportional relationship

Step-by-step explanation:

The equation that models a proportional relation is y=kx, where k is the constant of proportionality.

Based on your description, we have:

x          y

0          4

2          8

3          12

4          16

The graph of a proportional relation will always pass through the origin i.e the initial value is always zero.

The equation of this graph is not in the form y=kx.

Hence, the graph does not represent a proportional relationship because there is an initial value which is not zero.

Three people are kayaking. They all started at the same point and rowed in the same direction for 20 minutes.
Cloud [144]

We can make everything have the same denominator so we can add, subtract, and compare them:

The common denominator between 2, 4, and 8, is 8.

7/8 = 7/8

1/2 = 4/8

1/4 = 2/8

The question is if Laura rowed more, less, or the same to the combined distance of Daniel and Annabelle:

Laura : 7/8

Daniel: 4/8

Annabelle: 2/8

4/8 + 2/8 = 6/8

So Daniel and Annabelle's distance combined is 6/8, which is less than Laura's:

7/8 > 6/8.

This means that Laura rowed more than Daniel and Annabelle.
