the LCM of 12 and 15 is 60
Mrs. Dean 150 words per minute, already set up nicely for us
Mr. Kovacs 96 words per 3/4 minute
So we need to adjust 96 words per 3/4 minute to what ever words PER MINUTE.
So, a simple way to do this is change 3/4 to decimal, which would be 0.75 in this case. Knowing that 96 words per 3/4 minute is 25% less than what he would type in a minute, we simply multiple 96 by 1.25 to make up for the 0.25 missing.
Which would get us: Mrs. Dean: 150 wpm
Mr. Kovacs: 96(1.25)=120wpm
Therefore Mrs. Dean types at a greater rate of words per minute, 30 more words per minute to be exact.
Answer:
true
Step-by-step explanation:
Answer:
Below.
Step-by-step explanation:
This factors to the product of 2 binomials like (x + a)(x + b), where a and b are 2 numbers.
40 = 4 * 10 and 14 = 4 + 10 so the answer is
(x + 4)(x + 10).
If we expand this we will get back to the quadratic expression:
(x + 4)(x + 10)
= x(x + 10) + 4(x + 10)
= x^2 + 10x + 4x + 40
= x^2 + 14x + 40.
Answer:
62,500
Step-by-step explanation:
2,500 times 9 + 40,000 because he didnt get the raise the first year he started so its only times 9
