Answer:
$ 2.5
Step-by-step explanation:
Given that
Total Amount to be invested = P = $3400
Total Time of investment = t = 13 years
Rate of interest = r = 1.15 %
Lets calculate Simple interest first
As we know formula for simple interest is
Substituting the values
A = $ 3944.9
Lets now calculate the compound interest
As we know formula for simple interest is
As compound interest applies every 3 months so n =3
So,
A = $ 3947.4
Now Lets calculate how much more he will earn using compound interest.
It can be found by taking difference of compound interest and simple interest
Amount = 3947.4 - 3944.9 = $ 2.5
So Skyler must have earned 2.5 dollar more using the compound interest.
Mean-53.4
Median-46
Mode-35
Range-54
Good luck!
Answer:
157 for A and B
Step-by-step explanation:
180-23=157
Answer:
increased = addition
twice = multiply by 2
is = equals
a number = x
16+2x=-56
subtract 16 from both sides
2x=72
divide by 2
x=36
Step-by-step explanation:
<h2>mark me a brainlist</h2>
Let daniel's age = d and let jessica's age = j
let your current age = x and your wife's current age = y
x = 5d (given in question)
∴ x - 5d = 0
x + 21 = 2(d+21) (given in question)
∴ x + 21 = 2d + 42
∴ x - 2d = 21
We can solve these two rearranged equations simultaneously by multiplying the first equation by -1 and adding them. This gives us the following:
3d = 21
∴ d = 7
This means that daniel is currently 7 and (if we substitute d = 7 into one of the equations) you are 35. We use a similar method for your wife's and jessica's current ages.
y = 7j (given in question)
∴ y - 7j = 0
y + 8 = 3(j + 8)
∴y + 8 = 3j + 24
∴ y - 3j = 16
If we use a similar method of elimination we get this:
4j = 16
∴ j = 4
Hence, from this we can concur that daniel is 7 and jessica is 4.
