From the information given, the deposit is 4000$, interest rate is 2.75% the final interest amounts to 220$ but the time it will take to earn this interest is unknown. We will assume the interest earned is per annum.
The formula we use is I = Prt
Let simple interest be I which is 220
Let principal sum be P which is 4000
Let interest rate be r which is 2.75 %
Let time be t
We need t, so we say t = I / Pr
t = 220 / 4000 * 2.75/100
t = 220 / 4000 * .0275
t = 220 / 110
t = 2
Therefore the time it will take to earn 220 $ interest is 2 years.
Answer:
Step-by-step explanation:
To determine for which value of x a pair of expressions will be equal, we will need to set them equal to each other and then solve for x.
First, we can add 4 to each side
Now we can subtract 2x from each side
Now, just to check our answer, we can plug in our answer back into the original equation to see whether we get the same result for each side
4a+8
Add all A's together.
Add 5 and 3 together.
Mass × gravitational energy × height
= gravitational potential energy
= joules
by interrelating the formula,
mass (unknown) × 10 × 629.9
= 2033.76
unknown = 0.32??
this is my working ^ but I'm not positive that it's 100% correct!
The distributive property: a(b + c) = ab + ac
(x - 3)(4x + 2) = (x)(4x + 2) + (-3)(4x + 2)
= (x)(4x) + (x)(2) + (-3)(4x) + (-3)(2) = 4x² + 2x - 12x - 6
<h3>= 4x² - 10x - 6</h3>
