Answer:
$300
Step-by-step explanation:
In this question, we are simply asked to calculate the simple interest on $3000, at a rate of 20% paid after 6 months.
We can do this as follows. Mathematically, it should be remembered that:
S.I = PRT/100
In this case, we lost out the individual values as follows:
P = $3000, R = 20% and T = 6 months = 0.5years, S.I = ?
We substitute the parameters into the equation:
S.I = (3000 * 20 * 0.5)/100 = $300
Answer:
ones place
Step-by-step explanation:
Because it is one of the last numbers and that's usually where the ones place is at.
Answer:
x = 21
Step-by-step explanation:
3x + 18 + 4x + 15 = 180
7x + 33 = 180
7x = 147
x = 21
Answer:
Step-by-step explanation:
Im assuming you mean .
To solve for r means that you have to isolate it like c is currently. To do this you would have to divide by whatever it's multiplied by (in this case 2pi).
If you divide both the right and left sides by this you get
