What is the difference 14/15 - 5/12 written as a decimal?

Answers

Answer 1

Answer: 14/15 - 5/12

Common denominator is 60.

$(4 * 14)/(4 * 15) - (5 * 5)/(5 * 12)$

56/60 - 25/60

= 31/60 as fraction.
= 0.516 as decimal.

Answer 2

Answer: 14/15 - 5/12
= (168-73)/ (15*12)
= 93/180
= 31/60
= 0.5166666667

Show math equation of 5x + 6x equation

Answers

$5x + 6x = x(5 + 6) = x(11) = \boxed{11x}$

Answer:

11x

Step-by-step explanation:

You just combine the like terms in this case which is 11x because you do 5x + 6x it is like terms so just combine them and there is your answer!

A quadratic function has zeros of -2 and 14. Find its axis of symmetry.

Answers

Answer:

The axis of symmetry is 6

Step-by-step explanation:

The axis of symmetry is halfway between the zeros

Add the zeros and divide by 2

(-2+14)/2 = (12/2) =6

The axis of symmetry is 6

If a loan of $125,000 is for 10 years, and the interest rate paid was $65,625, what is the in treat rate on the loan?

Answers

for this problem you simply are solving for a different variable. we use the equation F=p(1+r)^T (assuming that the interest is compounded once a year). p=125,000 T=10 and we can add the interest plus the initial to get the final and find F=180,625. plug all these in and you get 180,625=125000(1+r)^10. solve for r in that equation and you get r=3.75%

if you want the work to solve the equation, first divide 180,625 by 125,000 and then take the quotient of that and put it to the 1/10 power. then minus 1 to solve for r (sorry for making it brief, it is a lot of numbers to type otherwise).

7 times blank equals 56

Answers

There are two ways to work this question out:

1. First you need to know how many times 7 can go into 56 and obviously 56 is in the 7 times table which is easy to find out. The answer would be 8. (7 * 8 = 56)

2. The other way is that you can just simply divide 56 by 7 which you will get the answer as 8.

I hope this helped! :)

*The answer is 8* because, If you divide 56/7 you get 8. If you have any more question like that always do the inverse operation. Example: 6 x ___= 42 the inverse or opposite operation is division because division is the opposite of multiplication like adding is to subtracting. So we would do 42/6 (Inverse operation) and we get 7. So, the answer to the question is 6 x *7* = 42. Hope this trick will help! (Subtraction & Division don't work the same! Only, Addition and Multiplication does!)

Describe how to write 0.0000672 in scientific notation

Answers

You have to remeber that you have to have a number that is less than 10, but equal or greater than 1! Okay since your trying to get between 1-10 with this number you would move the decimal point 5 places to the right. And since you are going back it is going to be negative so the answer would be 6.72*10^-5

To do this in scientific notation, find the first counting number (anything above zero that isn't a decimal). That is 6. Put a decimal after it. This would be it 6.72. Now count the places before the 6 and after that add 1 more place for the six itself. There is 4 numbers before the 6 and therefore, there is a total of 5. Since it is a decimal, it would be to the negative fifth power. Now multiply 6.72 by 10 to the negative fifth power and this would make it scientific notation. The equation that is written out would be 6.72 x $10^(-5)$
