Answer from: audreymvarney

10%

Step-by-step explanation:

first let's write out the problem

0.99 is what percent of 9.90 = 0.99=9.90*x

We need to what c is so we would do the opposite operation of multiplication, division so we get,

0.99/9.90= .1

now we turn .1 into percent and get out answer

0.1= 10%

Answer from: lexi7752

Step-by-step explanation:

ahh that's like a math tongue twister :P

so just remember that when you are given the final amount, as the 0.99 is, then you want to divide by the total, like this

0.99 / 9.90 =

we don't really need a calculator for this, b/c you can see that the answer will come out to a one, but, where is the decimal, huh

my calculator put the decimal here 0.1

so that's 10% right? which totally makes sense.. right? 0.99 is 10% of 9.90... just move the decimal one place in the 9.9 to get .99 see? so that kinda helps us know where the decimal goes in the answer, if that make sense? The decimal gets moved one place to the LEFT of the one, in our answer when we just did the math in our head.

anyway.. leave a comment if you have more questions :)

Answer from: Quest

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

Answer from: Quest

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph

there is a hike in both the graphs so the graphs are increasing on their domain.x-intercept of log x and log 6x are differentthere is a vertical asymptote of both the graphs so there is no y-interceptas both the graphs are increasing so there is no horizontal asymptote
