20 degrees clecuis juste bcause i know
16 / 25= 0.64
0.64*100=64
64% of the students bring cameras.
Answer:
m = -8
Step-by-step explanation:
-9 + 6m = -3m - 1 + 10m
-8 + 6m = 7m
-8 = m

Answer:
Step-by-step explanation:
In this geometry, there are three "geometric mean" relations that apply. They can be summarized by the rule ...
<em>a segment touching the hypotenuse is equal to the geometric mean of the segments of the hypotenuse it touches</em>.
For x and y, the two segments will be the short one (4 or 6, respectively) and the entire hypotenuse (4+6=10).
Using this rule, we have ...
x = √(4·10) ≈ 6.3
y = √(6·10) ≈ 7.7
z = √(4·6) ≈ 4.9
__
The geometric mean of two numbers is the square root of their product.
_____
<em>Additional comment</em>
These relations come about because all of the right triangles in this figure are similar. That means corresponding sides are proportional.
x/10 = 4/x ⇒ x² = 40
y/10 = 6/y ⇒ y² = 60
z/6 = 4/z ⇒ z² = 24
