Yes, for fractions you can multiply the denominator by the numerator. For square roots you can use the square root button.

You can try


well, a number is rational if it can be writtten in form a/b where a and b are integers and b≠0

integers are like -4,-3,-2,-1,0,1,2,3,4


irrational numbers can't be written in form a/b like that with integers

so if we had 2/3, we're done, no need to use calculator
note: all releating deciamals can be written as a fraction and are therefor rational

you can use a calculator, but if it's in fraction form, no need to do that
sometimes a number repeats but you might not be able to see it if you use a calculator

The answer to the problem
larisa86 [58]

She puts 8% of her salary in, so multiply her pay by 8% to get her yearly amount she saves:

45000 x 0.08 = $3,600 per year.

The company puts 6% of that in the account:

3600 x 0.06 = $216

So per year 3600 + 216 = $3,816 is saved.

3,816 x 2 = $7,632 is the 2 year total.

The answer is A.

Answer:

D) -4, 0

Step-by-step explanation:

find common difference.

the common difference appears to be +4 as you must add 4 to -12 to get to -8

now we find the missing terms.

the previous term of the first missing term is -8

if the common difference is +4 then the next term would be -8 + 4 = -4

the term after that would be -4 + 4 = 0

the two missing terms are -4 and 0
