Answer:
24
Step-by-step explanation:
4 years ago, Daniel would've been 4 and Kevin would be 20, so Kevin would've been 5 times as old as Daniel. And 8 x 3 = 24. So, Kevin is 24.
Answer:
You will put 1220.83ft³ of water in the pool
Step-by-step explanation:
First of all we have to calculate the volume of the pool and then calculate 80% of that volume
radius = half of diameter
d = 18ft
r = 18ft / 2 = 9ft
To calculate the volume of a cylinder we have to use the following formula:
v = volume
h = height = 6ft
π = 3.14
r = radius = 9ft
v = (π * r²) * h
we replace with the known values
v = (3.14 * (9ft)²) * 6ft
v = (3.14 * 81ft²) * 6ft
v = 254.34ft² * 6ft
v = 1526.04ft³
The volume of the cylinder is 1526.04ft³
If it is filled to 80% then we have to multiply the volume by 80/100
1526.04ft³ * 80/100 = 1220.83ft³
You will put 1220.83ft³ of water in the pool
Answer:
the final amount value is $4,274.58
Step-by-step explanation:
Given that
Present value = $3,500
Time period = 5 × 52 = 260
Rate of interest = 4% ÷ 52 = 0.0769%
We need to determine the final amount i.e. future value
So as we know that
Future value = Present value × (1 + rate of interest)^time period
= $3,500 × (1 + 0.0769%)^260
= $4,274.58
Hence, the final amount value is $4,274.58

Answer:
10.8109 amu
Step-by-step explanation:
The average atomic mass of boron is determined as the average of the atomic masses of both isotopes weighed by their respective abundances.
Therefore, the average atomic mass is given by:

The average atomic mass of boron isotopes is 10.8109 amu.
