<span>The answer is 2 people. Jim and Holly are 2 persons making 2 gingerbreads for 2 minutes. So, for both of them, 2 minutes are necessary for 2 gingerbreads. Let's calculate how many gingerbreads they can make for 400 minutes. 2 min : 2 gingerbreads = 400 min : x gingerbreads. x = 2 gingerbreads * 400 min : 2 min = 400 gingerbreads. So, the two of them can make 400 gingerbreads for 400 minute without anyone's help.</span>
Given:
A figure of a right triangle and an altitude form the right angle vertex to hypotenuse.
To find:
The value of x.
Solution:
From the given figure, it is clear that the altitude divides the hypotenuse in two segments x and 8.
Length of altitude = 18
If an altitude divide the hypotenuse in 2 segments, then according to the geometric mean theorem, the length of the altitude is the geometric mean of two segments of hypotenuse.
By using geometric mean theorem, we get
Divide both sides by 8.
Therefore, the value of x is 40.5.
Answer:
2
Step-by-step explanation:
|a+x|/2-|a-x|/2
Plug in the values.
|-2+-6|/2-|-2- -6|/2
Evaluate.
|-8|/2-|4|/2
Apply rule : |-a| = a
8/2 - 4/2
4 - 2
Subtract.
= 2
