Answer:
14 children
Step-by-step explanation:
If we know the ration, and we are given the adults, we can set up a proportion in order to solve for the amount of children there are.
5:2=35:x
5x=35*2
5x=70
x=14
There are 14 children
Formula for compound interest is stated as follows:
A = P(1+r)^n; where A = Amount in the bank after compounding, P = Principal amount deposited in the account, r = annual interest rate as a decimal, n = number of years to accumulate amount A in the account.
Using the values given;
9090 = P(1+0.058)^5
P = 9090/[(1+0.058)^5] = 9090/1.3256 = 6857.02
Therefore, the amount put in the account must be $6,857.02
The weight of the spherical sculpture in pounds is approximately 251607 pounds
<h3>How to find the weight of the sculpture in pounds?</h3>
The sculpture is spherical and its made of solid bronze.
Therefore,
density = mass / volume
where
density = 7700 kg / m³
volume = 4 / 3πr³
volume = 4/ 3 × 3.14 × 1.524³
volume = 44.4574491494 / 3
volume = 14.8191497165 m³
Therefore,
mass = 7700 × 14.8191497165
mass = 114107.452817 kg
1 kg = 2.205 pounds
114107.452817 = ?
cross multiply
mass in pounds = 114107.452817 × 2.205
mass in pounds = 251606.933461
mass in pounds = 251607 pounds
