Answer:
10 units
Step-by-step explanation:
Area of a triangle is 
= Area
where h is the height, and b is the base
We can substitute these values into the area equation and get:
Multiply both sides by 2:
x * 10 = 100
Divide both sides by 10:
x = 10
The missing side is 10 units long
Answer:
4.64c
Step-by-step explanation:
Answer:
No
Step-by-step explanation:
The second and third figures are translations of each other. The first figure appears to be a reflection of the second, not a translation. Hence the first and third figures are not translations of each other.
__
If an image is translated, all of the pre-image line segments are parallel to the image line segments. That is not the case for the first and third figures, in which the top line segments go in different directions.
We will be using the fact that 
, where 
is the probability that the first bulb works and 
is the probability that the second bulb works.
The probability that the first bulb works is 
. However, when we take one out (given that the first bulb works) we now have 19 working bulbs and 4 bad ones. This means that the probability that the second bulb works is 
.
Now, we can find our final probability:
