No because a mixed number is a whole number with a fraction and the smallest whole number is one so 1 and a fraction pulse and a fraction will equal more than 2

love history [14]

Answer:

v = 5.6m

Step-by-step explanation:

Proportional relationship equation:

y = kx, where k- constant of proportionality

Use the given point to work out the value of k:

28 = 5k
k = 28/5
k = 5.6

In our case the equation is:

v = 5.6m, where v- volume, m- mass

Answer:

1115322

Step-by-step explanation:

In 1906, San Francisco felt the impact of an earthquake with a magnitude of 7.8.

Claimed statement is he worst is yet to come, with an earthquake 142,990 times as intense as the 1906 earthquake ready to hit San Francisco.

We need to find the magnitude of their claimed earthquake.

It can be calculated by simply multiplying 142,990 by 7.8 as follows :

$E=142990 \times 7.8\\\\=1115322$

The magnitude of claimed earthquake is 1115322 .

The table shows the rates for sending text messages. Are the rates proportional? Explain.

Cloud [144]

Answer:

Yes

Step-by-step explanation:

Remember in order for the rates to be proportional it has to have a constant rate of change and it has to go through the origin if graphed

For one this has a constant rate of change which is 3 dollars per 25 messages

Now we just have to find out if it would go through the origin (0,0)

To do so we subtract 3 dollars and then 25 messages

6-3=3

50 - 25 =25

then again 25-25=0

3-3=0

concluding that (0,0) is a solution

Thus meaning that this is a proportional relationship
