Answer:
62 newspapers
Step-by-step explanation:
Let s represent the number of Sunday papers sold. Then s/2 is the number of Friday papers sold. The total revenue is ...
1.50s + 0.75(s/2) = 116.25
1.875s = 116.25 . . . . simplify
s = 116.25/1.875 = 62 . . . . . divide by the coefficient of s
62 Sunday papers were sold.
1.22 / 1,22
because:
100% of 100 is 100. You multiplied it by one.
110% of 100 is 110. You multiplied it by 1.1 / 1,1
So if you want to multiply by a percentage between 100 and 200 you have to multiply by a number between 1 and 2.
Answer: +42x
Step-by-step explanation:
The student only multiplied each term individually.
He should have (7x+3)² = (7x+3)(7x+3)
Which is 49x²+42x+9
Therefore the error is (42x) or the failure to apply the law of multiplication of variables in a bracket.
Answer:
The answer is 60 degrees.
Step-by-step explanation:
The three angles in any triangle add up to 180 degrees.
You know by the box at the bottom right that it's a right triangle and therefore that angle is 90 degrees. They also give you the 30 degree angle at the bottom left. So:
90 degrees + 30 degrees = 120 degrees.
180 degrees (total) - 120 degrees (first 2 angles) = 60 degrees (missing angle)

Answer:
3003
Step-by-step explanation:
We want to find out how many ways we can choose 10 players among 15 players (since the goalie is not interchangeable)
The number of different lineups you can have can be found by using combination:
