So lets remember the formula for interest first.
#lightbulb
here it is <span>A = P(1 + rt)
all we really have to do is plug in our rates, principles, and time into equation.
P = $800
t = 2 years
r = 6.5% or as a decimal 0.065
now lets look at our new equation that finally has numbers in it
A = 800[1 +(0.065)(2)] first lets take care of the 0.065 and 2 by multiplying them together. thus our new equation.
A = 800(1+ 0.13) then we add the 1 to the 0.13 and get 1.13
800(1.13) from here we just multiply and that equals 904
since we are looking for what is earned we take 904 and subtract 800 to get that answer. Here is the math.
904 - 800 = 104
he made 104 dollars in 2 years!
hope this is right.
have a good one:)
merry christmas:D

The ball takes 6 seconds to reach the ground.
<u><em>Explanation</em></u>
Height of the ball after 
seconds is represented by....
The height of the ball is 0 feet when it hits the ground. So, for finding the number of second the ball takes to reach the ground, <u>we will just plug 
into the above equation and then solve for .</u>
Thus...
Using zero-product property....
and
(Negative value is ignored as time can't be negative)
So, the ball takes 6 seconds to reach the ground.
Answer:
3,1
Step-by-step explanation:
(3+6)= 9
times 1 would also be 9.
Answer:
100
Step-by-step explanation:
Write in an equation:
4=4%x, then divide 4% from both sides, and then you get 100.
3*4 + 1*5 / 5*4=
12+5/20=
17/20
