Answer: the 4th one I think
Step-by-step explanation:
Answer: Choice B) 3 years
--------------------------------------
Explanation:
The simple interest formula is
i = P*r*t
where,
i = interest
P = principal
r = interest rate in decimal form
t = time in years
In this case,
i = 840
P = 7000
r = 0.04 (move the decimal point 2 spots to the left go to from 4% to 0.04)
t = unknown; we'll leave it as t
Plug the given values above and solve for, or isolate, t
i = P*r*t
840 = 7000*0.04*t
840 = 280*t
840/280 = 280*t/280
3 = t
t = 3
It will take 3 years
Answer:
5/2 = 2 1/2
Step-by-step explanation:
There are 2 parts in one half, meaning 2 halves equals 1.
If you have 5 halves, you of course would get an improper fraction.
To find the answer, dive the numerator by the denominator. 5 ÷ 2 gives you 2.5, or 2 1/2.
Think about it this way: How many times does will 2 go in to 5 evenly? Twice. 2 times 2 is 4, leaving you with one left over. Whatever the remainder is, is the numerator for the improper fraction, and the denominator stays the same.
