based on the number of mice that took part in the experiment, the total number of mice that had at least one effect is 20 mice.

<h3>how many mice had a health effect?</h3>

15 mice had at least 1 tumor while 4 mice had both a tumor and respiratory failure.

the number of mice with just a tumor is:

= 15 - 4

= 11 mice

the number of mice with respiratory failure alone is:

= 9 - 4

= 5 mice

Sheila can ride her bicycle 6000 meters in 15 minutes. How far can she ride in 2 minutes?
iren [92.7K]
<span>Sheila can ride her bicycle 6000 meters in 15 minutes. 
Forming that into a ratio, that will be 6000 : 15

Doing the proportion for 2  minutes.
6000 : 15 = X : 2

Doing the computation.
6000 / 15 = X / 2
15X = 2 * 6000
15X = 12000
X = 800

So Sheila covered a total of 800 meters in 2 minutes.</span>
