Answer: 121 2/3 days
Step-by-step explanation:
Number of days in a year = 365 days
Number of friends = 3 friends
The number of days each year that Alisa need to walk the dog will be:
= Number of days in a year / Number of friends.
= 365 / 3
= 121 2/3 days
= 121 days + (2/3 × 24hours)
= 121 days 16 hours
Note that 24 hours = 1 day
Answer:
Volume is 718 cm^3
Step-by-step explanation:
We need to get the radius of cylinder A
From the base area,
we have that;
A = pi * r^2
18 = 3.142 * r^2
r^2 = 18/3.142
r^2 = 5.73
r= √5.73
r = 2.39
If two shapes are similar, we have the ratio of their corresponding sides equal;
Thus;
2.39/5 = x/10
x = (10 * 2.39)/5
x = 4.78 cm
To get the volume, we use the formula
V = pi * r^2 * h
V = 3.142 * 4.78^2 * 10
V = 717.8 cm^3
This is approximately 718 cm^3
Answer:
The solution is:
Step-by-step explanation:
The first step to solve this equation is placing everything with the exponential to one side of the equality, and everything without the exponential to the other side. So
To find x, we have to apply log to both sides of the equality.
We also have that:
So
