1 in 10 is the probability of two people picking the same number.
Answer:
The unknown number is 90
Step-by-step explanation:
This question requires a good understanding so as to interprets it well
And always ensure that all symbols used in representation are well stated so as to help the examiner or anyone who will mark it to understand better
So back to the question,let the unknown number be x
And two thirds of the unknown number is 2/3x
2/3x was decreased by 20 which can be written as 2/3x-20
And this decrease gives 40
That's,2/3x-20=40
Then go ahead to solve the question
Start by finding the LCM and the LCM is 3
2x-60/3=40
Cross multiply
2x-60=40×3
2x-60=120
Collect like terms by adding 60 to both sides
2x=180
Divide both sides by 2
x=90
Therefore the final answer is 90
It would stop at 3y+4>11 because the 3y and 4 are unlike terms and can only be divided or multiplied.
To determine the common ratio of the geometric sequence, divide the second term with the first term. 480 divided by 768 equals 5/8. Further, the ratio of the third and second terms may be used to check the consistency of the common ratio. The ratio is also 5/8. Thus, the common ratio is 5/8.
Answer:
8 more minutes.
I think the perfect version in your question is:
<em>McGill types 270 words in six minutes his paper is 630 words if he keeps waving at the same rate and how many more minutes when McGill finish typing his paper</em>
Given that:
- 270 words in six minutes <=> 1 minute =
= 45 words
So, the total minutes he needs to finish the paper if he keeps waving at the same rate is:
= 
= 14 minutes.
So he needs 14 minutes to finish writing the paper, but he wrote 270 words in 6 minutes already, so it will take him 14-6 = 8 more minutes.
Hope it will find you well!
