Your body needs oxygen in order to efficiently break down glucose and process it into your cell's primary energy source (ATP). As you do more intense exercise, you need more energy and therefore more oxygen. Your blood carries oxygen from the lungs to your muscles. To keep...

math ugh.
20/20 - 9/20 = 11/20 Then, since the ratio between male and female is 11/20 / 9/20 = 11/20 * 20/9 = 11/9, we can use this to figure the amount of males. multiply by 2160 (number of females) to get 2640.

math ugh.
since 9/20 were female, 11/20 were male 11/9 * 2160 = 2640 males.

6 * 1 1/2 meters of cloth = 6 * 3/2 = 9 meters of cloth. a meter is roughly a yard. so we need about 9 yards. However, a yard is a bit less than a meter, so to make sure, buy 10 yards of cloth.

I believe I answered the question, just find the probability of 7 failures ( a 6/7 chance each time) 3 successes (a 1/7 chance each time) Then multiply.

True....I said that in a previous response.

I answered this kind of question before, so I won't get into detail. Before I showed that subtracting a negative number will move you right. It follows that adding one will move you left. Thus, TRUE.

8x = 2000 x= 250

Whew that is a lot of questions you are posting no offense! 3 4/5 is a mixed number, so we convert to improper fraction by multiplying 5 and 3 and adding 4. so we get 19/4 = 15+4/5 From this we can OBVIOUSLY see that 19/4 (4.75) is less than 15 + other stuff. So, FALSE.
