Just draw the graphs, and you should find y = 10x² is the only graph narrower than the given one.
Answer:
25
Step-by-step explanation:
2 out of 12 means also 1 out of 6.
so, a ratio of 1:6 or a factor of 1/6.
150 × 1/6 = 150 / 6 = 25
so, we expect that out of the 150 sold cars 25 have been red.
Answer: x = 9.0
Step-by-step explanation:
From the given right angle triangle,
the hypotenuse of the right angle triangle is x
With m∠39 as the reference angle,
the adjacent side of the right angle triangle is 7
The unknown side represents the opposite side of the right angle triangle.
To determine x, we would apply
the cosine trigonometric ratio which is expressed as
Cos θ = adjacent side/hypotenuse. Therefore,
Cos 39 = 7/x
x = 7/cos 39 = 7/0.777
x = 9.0 to the nearest tenth
Answer: 1.43 h
Step-by-step explanation:
Velocity is 
is defined as the change in position (displacement) 
of an object in a specific time 
:
Where:
is the car's velocity
is the distance the winner car traveled
is the time
Isolating :
Solving with the given information:
This is the winner's time
