John read the first 114 pages of the novel, which was 3 pages less than 1/3 of the novel.
sp2606 [1]
If they're asking you how many pages are in the novel, there would be 351. To find this, you just add 3 to 114, which is 117 and multiply it by 3, which is 351. If they're asking something else, let me know and I'll try to help. I hope this helps!

If (42)^p = 41^4, what is the value of p?
babymother [125]

First you need to make both bases the same:

Lets remove the ^p and ^4

To make the base of 42 equal to 41, you would have 41^x = 41

X - ln(42) / ln(41) = 1.00648904


Now you have 41^1.00648904(p) = 41^4


Now the bases are equal so we need to set the exponents to equal:

1.00648904(p) = 4

Divide both sides by 1.00648904 to solve for P

P = 4 / 1.00648904

P = 3.97421114

If you make an initial deposit of $1000 in an account that yields 5% interest
Genrish500 [490]

SI

$1 000 × 4 % × 10 = $400

CI

($1 000 × 1.04 ^10) - $1 000 = $1 480.24 - $1 000 = $480.24

Interest on interest only applies to Compound Interest.

Excluding year 1, which yields $40 [the same as SI] the interest on interest yields $480.24 - $40 = $440.24
