Do you know what 3.3 to the second power is?
galina1969 [7]
3.3^2 means 3.3 times itself 2 times or 3.3 times 3.3 or (use calculator)10.89
smaller powers (that's what 3.3^2 is, it means 3.3 to the second power) sometimes use different words to denote powers exg

x^2=x squared (square=2dimentionsl)
x^3=x cubed (cube=3 dimentionsl)
then x^4=x to the fourth, and so on

What is the length of side AB of parallelogram ABCD?<br> units<br> 4g - 8<br> B<br> q+4
Andrews [41]

Answer:

8 units

Step-by-step explanation:

» <u>Concepts</u>

Parallelogram Side Theorem states that the opposite sides of a parallelogram are congruent, meaning they have the same length.

» <u>Application</u>

In this case, we're asked to apply the theorem to find the value of q and then find the length of AB. Thus, we have to set up the equation 4q - 8 = q + 4.

» <u>Solving</u>

Step 1: Subtract q from both sides.

  • 4q-8-q=q+4-q
  • 3q-8=4

Step 2: Add 8 to both sides.

  • 3q-8+8=4+8
  • 3q=12

Step 3: Divide both sides by 3.

  • 3q/3 = 12/3
  • q=4

Step 4: Plug in the value of q for side AB.

  • 4(4)-8
  • 16-8
  • 8

Therefore, the answer is 8 units.

In the game kazoo teams lose one point each time they skip a turn they earn a point each time there team guesses correctly.
gogolik [260]
Given that the team starts with a score of 0, after skipping 8 turns they would have 8 points deducted and thus end up with a score of -8. Now if they guess 6 answers correctly this would add 6 points to their score and so they would end up with -8 + 6 = -2 points.

There are 442 boy students in class
poizon [28]

Answer:

520

Step-by-step explanation:

This problem is

boys + girls = total

Boys = 442

Girls = 15% of the total

Therefore, substituting in, gives us:

442 + .15t = t, where t is total

Then 442 = .85t and

t = 520
