Answer:
$2000
Step-by-step explanation:
The formula for simple interest is:
Where
i is the interest earned
P is the initial deposit
r is the rate of interest (in decimal)
t is the time
Now, in the problem, it is given:
i = 480
r = 4% = 4/100 = 0.04
t = 6
Now, we substitute and find the value of P (initial deposit):
Hence, the initial deposit was $2000
Answer:
Robert will fill the pool in 200 hours at a constant rate.
Step-by-step explanation:
120000 divided by 10 is 12000, then you divide that by 60 to go from the number of minutes to hours which equals 200. It's at a constant rate because it's 10 gallons PER minute.
Formula for area of circle:
A=πr²
Here diameter, d= 6 cm
Radius, r= d/2 = 6/2 = 3 cm
Put values
A= 3.14 x 3²
A=3.14 x 9
A=28.26 cm²
Answer: 28.26 cm²
Answer:
LCM(30;105)=210: least common multiple, calculated.
Step-by-step explanation:
30= 2x3x5
30 is not a prime, is a composite number;
105=3x5x7;
105 is not a prime, is a composite number;
*Positive integers that are only dividing by themselves and 1 are called prime numbers. A prime number has only two factors: 1 and Itself.
* A composite number is a positive integer that has at least one factor (divisor) other than 1 and itself.
Answer: 1874.5
Step-by-step explanation: If your starting balance is 3090$, and you withdraw 870$ and 465$ your subtracting, therefore leaving you with 1755$. If you deposit 109$ and earn 10.5$ in interest, you're adding, leaving your total to 1874.5$
