Answer: y is 5
Step-by-step explanation: The triangle on the left is double the triangle on the right. Since 10 on the bigger triangle is double, it would be half on the smaller triangle, so 5.
I would use a confidence interval to estimate the mean fuel savings because of the range of the data. If the data were close together, a simple mean would be enough. Here there is a wide spread of values between 48.3 and 6.9. A confidence interval would be a good representation of the values.
Answer:
The sum of the angles in any triangle is 180 degrees. If one of the three angles is 90 degrees (a right angle) the the sum of the other two angles is 90 degrees. Therefore each of the other two angles must be acute.
The statement is TRUE.

Answer:
both people actually did the same work
Step-by-step explanation:
Work = Force × Distance
The person that climbed the steep spiral staircase used more force but covered a shorter distance. On the other hand, the person that walked up a gentle ramp used less force but covered a longer distance. Since both people reached the same height, the force against gravity was the same.
