Answer:
They biked for 1 hour and 38 minutes
Step-by-step explanation:
Here, we want to know the length of the biking time
Mathematically, from the time given;
if they had ended the biking by 2:47
They would have biked for 2 hours
But, as it can be seen, the biking stopped at 2:25 and that is (57-25 = 22 minutes earlier)
So, the length of their biking time would be;
1 hour and (60-22) minutes
and that is 1 hour 38 minutes
Answer:
Dependent
Step-by-step explanation:
There is a 1/3 chance that 1 of the first 3 people will pick Jerry's favorite kind of doughnut
So I think it is dependent
The cost is the number of videos (V) times the cost of a video, plus the monthly fee.
C=2.25V+5
The account is starting off with 1500, so that will be the start value. Since it is simple interest, it will always be gaining 4 percent of 1500. Let's find 4 percent of 1500.
1500×.04= 60
The account will be growing by $60 every year.
1500+60x=y
X is the number of years. We can find the interest earned by multiplying 5, since that is the number of years we are trying to find, and 60, since that is the interest.
60×5= 300
The interest earned is $300 over 5 years.
Now let's find the balance of the account after 5 years.
1500+ 60(5)=y
1500+300=y
1800=y
The balance of the account will be $1,800 after 5 years.
7x-5y=21 when x=4 from the coordinate point of (4,y)
Next,
7x-5y=21
Substitute x with 4
7(4)-5y=21
28-5y=21
Add 5 to each side
28-5y+5y=21+5y
28=21+5y
Subtract 21 to each side
28-21=21+5y-21
7=5y
Divided 5 to each side
7/5=5y/5
y=7/5
Or
y=1 2/5
Check:
7x-5y=21
Substitute x with 4 and y with 7/5
7(4)-5(7/5)=21
28-7=21
21=21. As a result, (4,7/5) is your correct answer. Hope it help!
