Answer:
Ling's principal can hire new teachers in 54 different ways.
Step-by-step explanation:
Since Ling's elementary school principal wants to hire some new teachers, and 6 teachers applied for one 1st grade teaching job, and 3 teachers applied for one 2nd grade teaching job, and there is also a job opening for a 3rd grade teacher, and 3 teachers applied for the job, to determine how many different ways can Ling's principal hire new teachers the following calculation has to be done:
6 x 3 x 3 = X
18 x 3 = X
54 = X
Therefore, Ling's principal can hire new teachers in 54 different ways.
A=15 and the angles are 100 degrees. Thats because 6a=10=3a=55 due to alternate angles equal the same angle. so if you algebraically solve for a, you eventually get a=15. then plug in your a value into either or given equations. (i.e.. 6(15)+10= 100
Answer:
There were 90 questions in the test.
Step-by-step explanation:
He missed 88 questions on the test and scored a 2%. This means that the 88 questions missed correspond to 100% - 2% = 98% of the total number of questions, which is x. So
![0.98x = 88](https://tex.z-dn.net/?f=0.98x%20%3D%2088)
![x = \frac{88}{0.98}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B88%7D%7B0.98%7D)
![x = 89.8](https://tex.z-dn.net/?f=x%20%3D%2089.8)
Rounding up
There were 90 questions in the test.
Equation: 99 + 45x, with x as how many ever months.
After five months:
99 + 45(5) = 99 + 225 = $324.
