Answer:
15,000
Step-by-step explanation:
First, round both the numbers:
34,182 rounds down to 34,000
18,717 rounds up to 19,000
Subtract you're two rounded numbers
34,000 - 19,000 = 15,000
It should be 24 because all degrees in angles add up to 180 so you add 49 & 107 get 156 subtract and boom!
The product of the slopes would be -1 because the slopes of two lines that are perpendicular are opposite reciprocals (ex. 2 and -1/2 multiplied together would be -1)
Answer:
The total number of pencils that Mr. Moretti gives to his is 162.
Step-by-step explanation:
He puts 3 mechanincal pencils in each bag.
In each bag, there is also twice as many regular pencils, that is, 3*2 = 6 regular pencils.
So in each bag, 3 + 6 = 9 pencils.
What is the total number of pencils that Mr. Moretti gives to his students if he puts 3 mechanical pencils in each bag?
18 students, and each gets 9 pencils.
18*9 = 162
The total number of pencils that Mr. Moretti gives to his is 162.
