Answer:
852 miles
Step-by-step explanation:
We presume the speed is constant, so the satellite will travel 3/8 the distance in 3/8 the time.
... d = (3/8)·(2272 miles) = 852 miles
_____
1 minute is 1/8 of 8 minutes, so 3 minutes is 3/8 of 8 minutes.
Answer:
y=-5/3+6
Step-by-step explanation:
y=mx+b
m is the slope
b is the y-intercept
y=-5/3+6
, where s is equal to the number of students attending and x is equal to the week number.
All the triangles are similar, so you know the long side is twice the length of the short side.
x = 2·16 = 32
From the Pythagorean theorem,
z = √(8² + 16²) = √320 = 8√5
Then
y = 2z = 16√5
The appropriate choice is the 2nd choice,
x = 32, y = 16√5, z = 8√5
