- you can use the pythagorean theorem for this.
a^2 + b^2 = c^2
12^2 + 16^2 = c^2
144 + 256 = c^2
400 = c^2
- square root this.
c = 20
therefore, x = 20.
so option C.

If you need to solve the equation and don't know how let me know
Hello!
To solve this exercise, let's think a bit and choose the best option for each alternative.
<h2>(a) Karen's desk is about 3...</h2>
Well, a desk with 3mm or 3cm is too small, and with 3km is too big.
In this case, the best option is 3 meters (even though it's big, it's the best option).
<h2>(b) Dan's refrigerator has a mass of 80...</h2>
Usually, a refrigerator is heavy. So the best option is kilograms.
<h2>(c) The bucket holds about 5... of water.</h2>
5ml of water is too little, it fits in a spoon. The correct option is liters.
Answers:
a. meters
b. kilogr
No of bacteria present at midnight. = 6700+1680=8380
Answer: The required value is P(A ∪ B) = 0.73.
Step-by-step explanation: Given that A and B are two mutually exclusive events where
We are to find the following probability :
P(A ∪ B).
We know that
the intersection of two mutually exclusive events is null event. That is,
A ∩ B = ∅ ⇒ P(A ∩ B) = 0.
From the laws of probability, we have
Thus, the required value is P(A ∪ B) = 0.73.
