56 pages/4 hours = 126 pages/x pages
Then you cross multiply
56*x =4*126 ---> 56x=504
Then you divide 56 to both sides
56x/56=504/56
The 56 cancels on the left side and then you get
x=9
So your proportion are:
56 pages/4hours=126 pages/9 hours
To determine the scale factor of the dilation, we determine the distances between the endpoints of the two lines through the equation,
d = √(x₂ - x₁)² + (y₂ - y₁)²
Substituting the known values.
Line Segment 1: d = √(1 - 2)² + (4 - 8)² = 4.123
Line Segment 2: d = √(18 - 14)² + (12 - 1)² = 11.70
Dividing the answers will give us 0.352
Answer:
800-80w.
800-80(2)=800-160=640 left in 2 weeks.
800-80(3)=800-240=560
800-80(5)=800-400=400
800-80(7)=800-560=240
800-80(10)= 0. She has 10 weeks until all of her money is gone
Function: 800-80w
Range: 460
So first I saw that u need 1 adult with every 6 children so I did 6*4 and got 24. From that I got 4 adults with 2 leftover children. For the other class which has 28 children, u would still need 4 adults. Now since u said the teacher is included as an adult only 3 more are needed for the trip, and that is your answer.
