The answer would be 75 width
Answer:
70 feet
Step-by-step explanation:
This problem can be answered by using proportions based on similar triangles.
Notice that a person and its shadow on the ground form a right angle (therefore they can be considered the two "legs" of a right angle triangle)
The same runs for the tree and its shadow.
Since the inclination of the rays of the sun are the same at the same time for both objects (the boy and the tree), their hypothenuses form the same angles with the ground and therefore belong to similar triangles.
We can create the following proportion to solve for the shadow of the tree (ST) using the information provided: the height of the boy (HB), the shadow of the boy (SB), and the height of the tree (HT)
Answer:
221,760 feet per hour.
Step-by-step explanation:
665,280/3 = 221,760
Answer:
x=5, -1
Step-by-step explanation:
set the equation equal to 0: 2x^2-8x-10=0
divide both sides by 2 to get x^2-4x-5=0
next factor your new equation to get (x+1)(x-5)
set those equal to zero
now you have x+1=0 and x-5=0
finally, solve for x by subtracting 1 and adding 5
now you have your answer x= 5 and -1

Answer: Choice C</h3>
4/36 = 1/9
==============================================================
Explanation:
Circle the second row. This is where each of the red die results are "2"
Then look at the cases when the second die is less than "5". So we could have a 1, 2, 3, or 4 on this second die.
As you can see, there are 4 cases when the first number is a 2 (red) and the second number is less than 5 (white).
We have m = 4 cases we want out of n = 6*6 = 36 cases total.
m/n = 4/36 = 1/9 is our final answer.
