18 squared is 324, not sure if you are supposed to simplify it i'm guessing maybe. If yes then it is 3
√
2 or 4.24264068... If not well obviously 324 is greater than 5.
So the answer would be ( > ) because 5 is bigger than 4.24....
The exponent of 12 tells of how many prizes to count to the left of the decimal. Another example of how a scientific notation can make numbers easier to read is the diameter of a hydrogen atom, which is about 0.00000005 mm, and in Scientific notation is 5x10-8 5x10 -8mm.
Answer:
∠PST = 45°
Step-by-step explanation:
The diagonals of a square bisect the angles
∠SPQ = 90° ⇒ ∠SPT = 45°
Answer: 
Step-by-step explanation:
To solve for h, we want to get h alone. We need to use our algebraic properties.
[multiply both sides by 2]
[divide both sides by (a+b)]
Now that we have h alone, we know that .
Angle D is 60° because it is a supplementary angle, meaning 180 (straight line) - 120 (angle A) = 60°
