The unit rate is 22 gal/min. So, you have
Then, you have

Miranda
bought some apples and oranges at the store for fruit salad. Owen
bought three times as many apples and twice as many oranges. Miranda has
5 fruits in her bag, but Owen has 12 fruits in his bag. How many apples
did Miranda purchase?
Derive two simultaneous equations a + o = 5 and 3a + 2o = 12 make a = 5 - o substitute in 2nd equation and you find o = 3, Miranda buys 2 apples.
Answer:
Step-by-step explanation:
A typical red blood cell in human blood has a diameter of approximately 0.007 mm.
In scientific form =
The way we work this out is by working out the amount of lots of 25 seconds in an hour, and then multiply it by that 1/4 of an hour. 1 hour has 60 minutes, and each minute has 60 seconds, so 1 x 60 x 60 = 3600 = the number of seconds in an hour.
3600/25 = 144. Therefore there are 144 lots of 25 seconds in an hour. If the deer runs 1/4 a mile in 25 seconds, then we just have to do 144 x 1/4 and it will give us the answer.
144 x 1/4 = 36. Therefore the deer can run 36 miles per hour.
If you want to express this all in one equation, we can write it as:
((60 x 60)/25) x 1/4 = 36
Hope this helped :))
