Answer:
The last expression is correct
Step-by-step explanation:
We have been given the following expression for simplification;
The bases of the two expressions are the same. They are both equal to 4. When multiplying numbers with the same base, we simply add their exponents. In this case our exponents are;
4 and -9
adding them we have;
4 + (-9) = -5
The simplified expression thus becomes;
Answer:
5/18
Step-by-step explanation:
The attached chart shows all 36 outcomes, equally likely.
There are 6 outcomes that are doubles (along a diagonal), 5 outcomes that have a sum of 8, but the (4, 4) outcome should only be counted once!
You're interested in 6 + 5 - 1 = 10 outcomes out of the 36 possible outcomes.
Probability of double or sum = 8: 10/36 = 5/18
Answer:
<h2><em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>39</u></em><em><u>°</u></em></h2>
Step-by-step explanation:
As per condition,
3x - 17° + 2x + 2° + 90° + 90° = 360°
<em>[</em><em>Since</em><em> </em><em>angle</em><em> </em><em>sum</em><em> </em><em>property</em><em> </em><em>of</em><em> </em><em>quadrilateral</em><em>]</em>
=> 3x + 2x - 17 + 2 + 90 + 90 = 360
=> 5x = 360 + 17 - 2 - 90 - 90
=> 5x = 195
=> <em><u>x = 39 (Ans)</u></em>
Answer:
Yes, they are equalent
Step-by-step explanation:
12:14 = 6:7
60:70 =6:7
both can be simplified to 6:7
Campatible #s are like rounding ok, it lets u round to a easier number that u can divide easier
