Answer:

14/33

Step-by-step explanation:

The total amount of beads is 8+4 = 12.  8 of these are black beads, so that is what we want, so 8/12 or 2/3.  For the second one, one black bead is already taken so 8-1 = 7 are left and for the total 12 - 1 = 11 are left, so 7/11.  Multiply this by 2/3 and we get 14/33.

Which of the following is equivalent to (5)^7/3
kifflom [539]
<em>The answer is \sqrt[3]{ 5^{7} }</em>

The reason we get this answer is because when you are converting from exponential form, to radical form you always place the numerator as our constant's exponent in the radical <em>( 5^{7} is called the radicand because it is located in the radical)</em> and the denominator in front of the radical, where it would be called the index. 

<em>Here's what a formula would look like:</em> ( \sqrt[n]{x} ) ^{q}=x^{ \frac{p}{q} }

Thank you for your question! I hope this helped! Have an amazing day and feel free to let me know if I can help you further! :D

Plz help ASAP which choice is it and why ?
Delicious77 [7]

Answer:

i think it would be choice D

Step-by-step explanation:

this would be because the 20 is 19.8 tons rounded up, the (1.1) is the increase of the original amount plus the 9.8 rounded up, and the (1.05) is the increase by 5.1. the reason why they multiply these like 20(1.1)(1.05) is because each number in the parenthesis is the increase, when you multiply something by 1.1 it will give you it's 100% + the 10% growth, same goes for the 1.05 which will give you the 100% + the 5% of 20(1.1)

in other words if you just multiplied by .1 you would only get 10% of what you're seeking while if you multiply by 1.1 you would get the 110%. the 1 is 100%, and the extra percentage you seek is the decimal (number behind the dot) that follows
