Mathematics

If we have the problem: 3 times 1.2, and if we estimate the product, we get (3 times 1) 3. If you really do multiply it out, then you get 3.6. But what if you didn't know that, and you put 0.36. 0.36 is say off from our estimated product: 3. Therefore, we know that 0.36 is wrong, and 3.6 is correct (or reasonably correct), because 3.6 is close of 3. I hope this helps! :D

Given that ∠CEA is a right angle and bisects ∠CEA, which statement must be true?
loris [4]
Given that ∠CEA is a right angle which has been bisected by BE, then:
∠CEB=∠BEA
thus each angle will be complementary to each other, hence the size will be:
90/2=45°
hence the correct statement.

Which is the area of a square with one side that measures 1 foot? A. 1 square inch B. 100 square inches C. 144 square inches D.
cluponka [151]

Answer:

Option C. 144 square inches is the correct answer.

Step-by-step explanation:

We have been given a square with one side with a measurement of 1 foot and we have to calculate the area in square inches.

First we know that 1 foot of length = 12 inches on scale

Therefore side of the square is 12 inches

Now the area of the square will be = (Side×Side) = (Side)²

                                                          = (12)² = 144 square inches.

So the area of the square will be 144 square inches.
