First u add d and then divide by x
It takes 4 years for a principal of $25,000 at a simple interest rate of 5% to become 30,000
<em><u>Solution:</u></em>
Given that:
principal = $ 25000
rate of interest = 5 %
Total amount = $ 30000
Number of years = ?
Formula used:
Total amount = principal + Simple interest
30000 = 25000 + Simple interest
Simple interest = 30000 - 25000
Simple Interest = $ 5000
<em><u>The simple interest is given as:</u></em>
Where, "p" is the principal
"n" is the number of years
"r" is the rate of interest
Substituting the values in formula, we get
Thus it takes 4 years for a principal of $25,000 at a simple interest rate of 5% to become 30,000
Answer:
904
Step-by-step explanation:
According to PEMDAS, we must multiply 100 and 9 first, which gets us 900. Then divide 12 by 2, which gets us six. 900 - 2 + 6 = 898 + 6 = 904.
Answer: b) they loaded 112356 lbs of cargo
Step-by-step explanation:
When a boat or an object floats in water, the volume of water that it displaces is equivalent to its weight.
When moving into the port, the cargo boat displaced 2200 ft³ of water. Since the density of water is 62.42 lb/ft³ and mass = density × volume, then the mass of the cargo boat on entering the port is
2200 × 62.42 = 137324 lbs
On leaving the port, it displaces 4000 ft³ of water. The mass of the cargo boat on leaving the port is
4000 × 62.42 = 249680 lbs
The difference in both masses is
249680 - 137324 = 112356 lbs
Therefore, they loaded 112356 lbs of cargo
