First you want to find how many words she types per hour.
There are 60 minutes in 1 hour.
So multiply 70 words/min times 60 min/ 1 hr to cancel out the minutes.
You will get 4200 words / hr
Then multiply 4200 by 4 and 5
use * as multiplication symbol
4200 words/hr * 4 = 16,800 words/hr
4200 words/hr * 5 = 21,000 words/hr
She will type 16,800 - 21,000 words/hr
So Your answer is going to be letter G
The teacher would have to grade 322 problems
14 (problems) x 23 (students)
Answer: 322
Answer:
Step-by-step explanation:
<u>Given sequence:</u>
<u>It is an AP with:</u>
- The first term is a = -4
- Common difference is d = 5
<u>Nth term of this sequence is:</u>
- aₙ = a + (n - 1)d
- aₙ = - 4 + 5(n - 1) = -4 + 5n - 5 = 5n - 9
Correct option is d.
The other number could be any number that isn't an even number. For instance: 1,3,5,7,9,11,13,15,17... (you get it)
