The
amount of interest earned from a specific investment can be calculated by
multiplying the principal amount with the decimal equivalent of the given
percentage or interest rate. That is,
<span> I = P x i</span>
Substituting
the known values,
<span> I = ($580)(0.615)</span>
<span> I = $356.7</span>
<span>Answer:
$356.7</span>
11:59 a.m to 12:59 p.m. = 13 hrs....and 12:59 p.m to 1:01 p.m = 2 minutes....so the elapsed time is 13 hrs and 2 minutes
Answer:
Kayleigh will have a total of $4608.
Step-by-step explanation:
First, you use the formula, I=PRT (Interest=Principal, Rate, Time), then you distribute the numbers: (I=4500x0.8%x3) when you multiply them all, you get $108, then you lastly add 108 to 4500, and you get your final answer of $4608.
Answer:
Step-by-step explanation:
I'm assuming that strange looking thing is a 9, so begin by multiplying both sides by that denominator to get:
then subtract 3 from both sides to get
and then square both sides to get
and get everything on one side to solve for x by factoring:
and factor that however it is you have learned to factor second-degree polynomials to get that
x = 16 and x = 9. We have to check for extraneous solutions because anytime you manipulate an equation, as we did by squaring both sides, you run the risk of these solutions that actually don't work when you plug them back into the original equation. Let's try 16 first:
If 16 is a solution, then this statement will be mathematically true.
and 
so 16 works. Let's try 9:
We know that one doesn't work, because 9-9 = 0 and 0 over anything = 0, not 1.
x = 16 is the only solution.
