Ella bought 8 meters of ribbon for $10.

Zanzabum

Answer:

$0.03 per inch

Step-by-step explanation:

We need to convert 8 meters to inches first.

Unit ratio for meters to cm is:

$\frac{1m}{100cm}$

So 8 meters is 800 cm

Now,

we need to convert 800 cm to inches

Unit ratio for cm to inches is:

$\frac{2.54cm}{1inch}$

So, 800 cm is :

$\frac{800}{2.54}=314.96$ inches

To get costing per inch, we divide total cost ($10) by the total number of inches (which is 314.96):

$\frac{10}{314.96}=0.032$

Rounded to nearest hundredth, $0.03 per inch

A baseball player had 4 hits in 8 games. At this rate, how many hits will the baseball player have in the next 28 games?

hoa [83]

Answer:

Step-by-step explanation:

I would say 14 because if you multiply 8 by 3 it would equal 24. And that is just below 28. Then, I tried to see if 8 x 4 would work, but that equaled 32. And both of those numbers are in between 28. So, if I multiplied 8 by 3 to get 24, I also multiplied the 4 by 3 which equals 12. So, I would say it would be 14.
