4 0

Answer:

a^8 ÷ b^12

Step-by-step explanation:

a^-5 · b^-4 / a^-13 · b^8

when dividing exponents with the same bases, subtract the exponents

a^8 · b^-12

do not leave a negative exponent; put it into the denominator and it becomes positive

b^-12 = 1 /b^12

The students in Steven's class got to choose between pizza and burgers for the
Rainbow [258]
Answer:
95% picked pizza
Step-by-step explanation:
We can get this answer by following a few different steps. Firstly, we need the total amount of students. We get this number by adding the amount of students who wanted pizza (19 students) and the amount of students who wanted burgers (1 student). When we add those we get the total number of students, which is 20. Now, we can set up a fraction to see what amount of students out of the total number of students wanted pizza.
This would be 19/20
Now, you plug this in your calculator and will get 0.95
To turn this, or any other decimal, into a percentage you multiply by 100%.
So, multiply 0.95 x 100% = 95%

Hope this helps :)
