In any scientific calculator log2(n) can be  calculated with either ln or log function as follows

Log2(n)= ln(n) / ln(2)

Or
Log2(n)=log(n) / log(2)

both will give nearly the same answers

### Column 75" tall, 16" wide and 16" deep. How many sq feet of stone to cover the column and top?

you have a rectangle of of 75 X by16 and you have 4 of those rectangles so multiply 75 X 16 and then multiply the sum by 4
then you have the ends which are squares of 16 X 16 so multiply 16 X 16 Nd then multiply the sum by 2
then add the 2 sums together to get the total square inches of the surface of the object
now one square inch =.00694 square feet so multiply the total sum by .00694 to get the area in square feet

### If i work 16 hours a week how much money do i get for a 14 year oldd

Multiply hourly wage by number of hours in pay period.
The answer is your gross pay. If this is un-taxed income, you earn that much. If it is taxed, then multiply by about 0.70 to determine take home pay after taxes, although taxes vary by location.

Ex: If I work 16 hours at \$9.50/hr, I make \$152/week before taxes, but only take home \$106.40 (\$152 x 0.70) per week after the government takes its cut.

Use a calculator, hand-held or on the computer in accessories, cell phone app, or pencil and paper with simple multiplication formula Wage x Hours Worked Per Pay Period x (1.00 - Tax Rate) = Take Home Pay Per Pay Period.

### What to numbers can you multiply to get 280 and add to get-18?

When you say "to numbers" I assume you meant "two numbers."

There is no solution.

For the product of two numbers to be 280, either both numbers must be positive or both numbers must be negative. For the sum of two numbers to be -18, one or both numbers must be negative. Taken together, both numbers must be negative.

We can find two numbers that multiply to 280 and add to +18, then simply take the negative of both numbers.

The square root of 280 is about 16.7. The sum of any two numbers that multiply to 280 must be at least twice that, or at least 33.4. Since 33.4 is greater than 18, there is no solution.

If you want to do it the hard way, take any pair of negative numbers that multiply together to 280, add them together, and see how close you come to -18. For example, -1 and -280 add to -281. -2 and -140 add to -142. -4 and -70 add to -74. -5 and -56 add to -61. -7 and -40 add to -47. -8 and -35 add to -43. -10 and -28 add to -38. -14 and -20 add to -34, which is as close as you can come in the integers.

### Pls i need equation for :- The sum of N1200 is invested in three project X,Y,Z at the ratio of 4,5,6 respectively. The expected cash inflow per annum is N700. the combined income for projects X and Y is...

Two ways to get to the same answer:
1) If X,Y, & Z are invested in the ratio of 4:5:6 then the amount invested in Z is 6/(4+5+6) times the total of N1200
= 6/15 * 1200
= N480
(Note: X is 4/15 and Y is 5/15 of the total investment,
4/15 + 5/15 + 6/15 = 15/15)
2) The second sentence says: Income from X plus income from Y minus income from Z is N140 and total income is N700. Total income is 700/1200 of the investment.
As formulas:
(Inc X + Inc Y) - Inc Z = 140 (rewriting: Inc X + Inc Y = 140 + Inc Z)
Inc X + Inc Y + Inc Z = 700
Substituting second formula into third:
(140 + Inc Z) + Inc Z = 700
140 + 2 Inc Z = 700
2Inc Z = 700 - 140 = 560
Inc Z = N280
Inc Z is also 700/1200 of investment in Z.
N280 = 700/1200 investment in Z
Investment in Z is 1200/700 * N280
Investment in Z is N480.

### On the Sharp EL-738 calculator, how do I find the interest rate? The question is: Jane earns \$300 interest over four years on her investment of \$1,200. What annual simple interest rate does this...

Hi,

Jane starts with 1200\$ at the beginning of the first year, and at the end of the fourth year she has 1200\$+300\$=1500\$
Use x for her annual interest rate, that means at the end of the first year she will have 1200\$*[(100+x)/100]. At the end of the second year her first-year money earns at the same rate, so she will have 1200\$*[(100+x)/100]*[(100+x)/100]=1200\$*[(100+x)/100]^2 at the end of the second year.
At the end of the third year she will have 1200\$*[(100+x)/100]^2 *[(100+x)/100]=1200\$*[(100+x)/100]^3
At the end of the fourth year she will have
1200\$*[(100+x)/100]^3 *[(100+x)/100]=1200\$*[(100+x)/100]^4 which is equals to 1500\$

1200\$*[(100+x)/100]^4=1500\$ divide both sides by 1200\$
[(100+x)/100]^4=1,25 take the fourth root of both sides
(100+x)/100=1,05737 both sides*100
100+x = 105,737 both sides -100
x=5,737
So Jane's annaual interest rate was 5,737%.

Hope it helps you.
