If 40% of students prefer keyboarding, 40/100*40=16 students like it best. If the remaining students prefer English, then 40-16=24 students like English best. Since 24 is more than 16, most students prefer English.
Answer:
The nth term is 109-9n
Step-by-step explanation:
Here, we want to find the nth term of the given arithmetic sequence
Mathematically, we have the nth term as;
Tn = a + (n-1)d
where a is the first term which is 100 in this case
d is the common difference which is the value obtained by subtracting the preceding term from the succeeding term; it is constant throughout the sequence
The value here is thus;
82-91 = 91-100 = -9
Substituting these values
Tn = 100 + (n-1)-9
Tn = 100 -9n + 9
Tn = 100 + 9 - 9n
Tn = 109-9n
There is no equals sign. Are we looking for x, or y?
Either way, with the -5 exponent outside the parentheses, you can multiply that to each exponent in the fraction to get rid of it.
I'm not sure what you mean by 2x^12y^3. Is it an exponent within another exponent?
Answer:
5/7
Step-by-step explanation:
Multiplying -15 by 60 yields -900, so the amount of water in the pool changes by -900 gallons in one hour.
