Meg used 15 gallons. First you find the lowest common denominator to add 11 1/2 and 6 4/5, which is 10. What you do to the bottom you have to do to the top. You multiply 2 and 5, which gives you 10. 1 times 5 is 5... 11 5/10. 2 times 5 is 10, 4 times 2 is 8... 6 8/10. Add 11 5/10 and 6 8/10 and it gives you 18 3/10. To find out how much she used subtract the total amount she bought and how much she returned home with. The fractions cancel out since 3/10 minus 3/10 equals 0. You're just left with 18 minus 3, which is 15.
Answer:
16819200
Step-by-step explanation:
If Dawn is 32 years old, how many minutes has she lived ?
60 minutes = 1 hour
60 x 24 hours = 1440 minutes in a day
There are 365 days in a year, and Dawn already lived 32 years. So ,
1440 minutes x 365 days equals to 525600 minutes in a year .
So , 525600 minutes x 32 yrs = 16819200 minutes .
So Dawn has lived 16819200 minutes
First put it in standard form:
<span>x^2 −14x -15 =0
a =1 b =-14 c=-15
Then use the quadratic formula:
x = [-b +-sq root (b^2 - 4ac)] / 2a
x = [--14 +- sq root (14^2 -4*1*-15] / 2*1
x = [14 +-sq root (196 +60)] / 2
</span><span>x = [14 +- 16] / 2
x1 = 15
x2 = -1
