Answer:
8 feet
Step-by-step explanation:
First I used the proportion method to set up the numbers. I used x for the height of the tree.
x/9 = 4/4.5
Notice that the height of the tree and Otis's height are both the numerators (top numbers) of the fractions. Also, the height of the tree and the length of its shadow are one fraction, and Otis's height and his length are another separate fraction.
Same with the length of the tree's shadow and the length of Otis's shadow. They are both denominators (bottom numbers) of the fractions.
Next, I did 4 times 9 and got 36. Then I did 36 divided by 4.5 and got 8.
You're welcome! :)
X=(1/2)x+3. Parallel lines have the same slope. Mark the point (-2,2) on a graph and then go up one unit, and then to the right 2 units until you have the line and the Y-intercept.
Let "a" the measure of an angle
let "s" be supplement
a= 6s+5
It's the first one if I'm not mistaken
Speed is the magnitude in a velocity. It is a scalar quantity so it does not have direction unlike velocity which is a vector quantity. Speed and velocity refers to the distance traveled by a moving object per unit of time. We calculate speed as follows:
Speed = distance / time = 84 miles / 2 hours
Speed = 42 miles per hour
