Step-by-step explanation:
We are given equation of parabola as
we can also write as
now, we can compare
and find a , h , and k
a=1
h=0
k=0
now, we can use focus formula
now, we can plug values
Answer:
Step-by-step explanation:
Let the number of minutes in 6.1 hours be x. Remember that there are 60 minutes in one hour. Therefore,
If 60 minutes = 1 hour,
Then
x minutes = 6.1 hours
Cross multiplying, it becomes
x × 1 = 6.1 × 60 minutes
x = 6.1 × 60 minutes/1
Therefore, the correct ratio with which 6.1 hours would be multiplied is
60 minutes/1 hour
Answer:
11 6/9
Step-by-step explanation:
Daniel works in a market
He has large bags of potatoes that weighs 26 1/4
Daniel is going to sell them in smaller bags 9/4 pounds each
Therefore the number of smaller bags of potatoes in which Daniel would have filled can be calculated as follows
= 26 1/4 ÷ 9/4
= 105/4 ÷ 9/4
= 105/4 × 4/9
= 105/9
= 11 6/9
