First you need to move the decimal as many times to the right till it is a whole number then on the other number you need to do the same amount decimal moving then continue with long divison
Answer:
2/5; 0.4; 40%
Step-by-step explanation:
Probability is going to be the number of seventh graders divided by the total number of students.
In this case, there are 8 seventh graders and 20 students. So, set up your fraction to be 8/20. This can be simplified to 2/5.
Now, you can divide 2/5 using long division or use your calculator, if permitted, to convert 2/5 to a decimal. You will get 0.4.
You can also figure this out by thinking that 2/5 = 4/10, so 4/10 = 0.4.
Now for percents, just move the decimal point of a decimal number two spaces to the right. If we have 0.40, we move the decimal point to the right twice to get 40, and add the percent sign to get 40%.
Answer:
we conclude:

Step-by-step explanation:
Given


To determine
In order to determine f(g(7)), the first step we need to do is to determine g(7)
so substitute x = 7 in g(x) = 2x + 2




so now we have

The next step to do is to substitute x = 16 in f(x) = 4x + 21




so we have

Therefore, we conclude:

The perpendicular line would have a slope of A) -3/2.
Perpendicular lines have opposite and reciprocal slopes.
To do the opposite, take the original slope (2/3) and change the sign (-2/3).
To do the reciprocal, take the slope we changed (-2/3) and flip it as a fraction (-3/2).
This gives us a new slope of -3/2.
Lol i’m not 100% sure but i’m am guessing 103 because it would be simplified
