Answer:

I believe 2 is b or C. 3.c

Step-by-step explanation:

Since there is more heads than tails, we know it's going to be bigger. Since there is not an exact half, and heads is 8, it is going to be one of the 0.533.

Since there are 52 cards in a real deck, there's only 4 cards of each. Since you almost double the amount of cards, it's going to be more than 4, but less than at least 15.

Which is equivalent to sqrt x^10<br> A. X-5<br> B. X -1/5<br> C. X sqrt 10<br> D. X 1/5<br> E. X^5
Lesechka [4]
<h3>Answer:  E) x^5</h3>

\sqrt{x^{10}} = x^5

=====================================================

Explanation:

We simply take half of the exponent 10 to get 5. This applies to square roots only.

So the rule is \sqrt{a^b} = a^{b/2}

A more general rule is

\sqrt[n]{a^b} = a^{b/n}

If n = 2, then we're dealing with square roots like with this problem. In this case, a = x and b = 10.

∠A and ∠B are vertical angles. ∠A = 65x − 12 and ∠B = 43x + 10 How many degrees are in ∠A?
Margarita [4]

Answer:

53 degrees

Step-by-step explanation:

Vertical angles are congruent so...

65x-12=43x+10

22x=22

x=1

Then add it into the equation of ∠A

m∠A= 65(1)-12

65-12

53

360 kilometers is 24% of how many kilometers.
Katena32 [7]
Do 360 <span>÷ 24/100. Flip the fraction so that it is now 360 x 100/24. Make that   360 x 100/24. That is then 36000/24. Do the division and then you get 1500.
