A possible sizes two teams of 9 or 9 teams of 2, 6 teams of 3 or 3 teams of 6
B yes 3 lanes could divide her 18 students by putting 6 people in each lane
18/3= 6
Answer:
Juan got 18.50 miles per gallon.
Step-by-step explanation:
We are given the following in the question:
Odometer in the beginning of trip = 1460.3 miles
Odometer at the end of trip = 1830.2
Gallons of gas used for trip = 20 gallons
Distance of trip =
= Odometer at the end of trip - Odometer in the beginning of trip
Thus, the trip was of 369.9 miles.
Miles per gallon =
Thus, Juan got 18.50 miles per gallon.

Answer:
Each Angle of Decagon = 144 degrees
Step-by-step explanation:
The interior angles of a decagon add up to 1440
If they are of the same measure, then every angle will be equal to:
Each Angle of Decagon = 1440/10
Each Angle of Decagon = 144 degrees
In order for the triangle to be called an isosceles right triangle, it must satisfy both conditions: XZ and XY must be perpendicular to each other, and XZ = XY.
To determine whether two lines are perpendicular, their slopes must be negative reciprocals of each other.
Solving for the slopes of XZ and XY:
slope of XZ = (y₂-y₁) / (x₂-x₁) = (6-3)/(5-1) = 3/4
slope of XY = (y₂-y₁) / (x₂-x₁) = (3--1)/(1-4) = -4/3
-4/3 is the negative reciprocal of 3/4, therefore XZ and XY are perpendicular to each other.
Solving for distance:
XZ = √[(y₂-y₁)²+(x₂-x₁)²] = √[(6-3)²+(5-1)²] = 5
XY = √[(y₂-y₁)²+(x₂-x₁)²] = √[(3--1)²+(1-4)²] = 5
<span>The slope of XZ is 3/4, the slope of XY is -4/3, and XZ = XY = 5. </span>
