Hello from MrBillDoesMath!
Answer: 1/3 (or 33 1/3 %) and 42 teachers
Discussion:
Part 1. If 16 out of 24 students made at least 80%, then 24 - 16 or 8 students made less than 80%.
Students who scored less than 80% / total number of students =
8/24 = 1/3
Part 2.
3 teachers for every 57 students so
3/57 = t/798 where t is the number of teachers
Multiply both sides by 798:
3/57 * 798 = t =>
3/57 * (14 * 57) = t as 798 = 14 * 57 so cancelling the 57's.
3* 14 =t
or t = 42
Thank you,
MrB
Answer:
3x^2 +8x +3
Step-by-step explanation:
(6x^2 + 8x - 3) - (3x^2 - 6)
Distribute the minus sign
(6x^2 + 8x - 3) - 3x^2 + 6
Combine like terms
3x^2 +8x +3
Answer:
![670\leq F\leq 790](https://tex.z-dn.net/?f=670%5Cleq%20F%5Cleq%20790)
Step-by-step explanation:
The process takes place at a temperature greater than or equal to 690 F but less than or equal to 790F, the inequality would be expressed as follows:
![670\leq F\leq 790](https://tex.z-dn.net/?f=670%5Cleq%20F%5Cleq%20790)
