278 is rounded to 280 (to the tenth). Anything that is above 5 you right. In case this is 8 so you round. If it is below 5 then you do not round.
Answer:
2a +2b +4
Step-by-step explanation:
The perimeter is the sum of the lengths of the three sides. If x represents the length of the third side, then ...
(3a +8) +(5a +b) +x = (10a +3b +12)
Subtracting from the equation everything on the left side that is not x, we get ...
x = (10a +3b +12) -(3a +8) -(5a +b)
= a(10 -3 -5) +b(3 -1) +(12 -8)
= 2a +2b +4
The length of the third side is 2a +2b +4.
Answer: There are 96 students who attend Chess club on Wednesday.
Step-by-step explanation:
Since we have given that
Total number of students in challenger Middle school = 800
Percentage of students stay after school for chess club in Wednesday = 12%
So, Number of students who attend Chess club on Wednesday is given by
![\frac{12}{100}\times 800\\\\=12\times 8\\\\=96](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B100%7D%5Ctimes%20800%5C%5C%5C%5C%3D12%5Ctimes%208%5C%5C%5C%5C%3D96)
Hence, there are 96 students who attend Chess club on Wednesday.
Answer:
1/q^30 (startfraction 1 over q subscript 30 baseline end fraction)
Step-by-step explanation:
just took quiz
To determine how much you get per hour, divide 44 by 4, 88 by 8, and 132 by 12. Each time you get 11, so you get 11 dollars an hour.
If y = money earned and x = number of hours worked, then
y=11x
because the money you get is 11 times the amount of hours you work.
Hope this helps and I can provide further explanation if needed!
