Answer:
Step-by-step explanation:
Given: 
, 
, 
,
.
To find: The elements in the set 
.
Solution:
We have,
Now, will contain all the elements in the set 
and all the elements in set 
.
So, .
Hence, .
If it is (5^10)/(5^2) then when you divide by powers you just subtract the two powers. So it would be (5^8) which is five to the eighth power
Answer:
59%
Step-by-step explanation:
13/22=.59 or 59%
Take the amount she drank and divide by the total size of soda.
8,425 ÷ 10.25 = 821.95
You would round up so to earn $8,425 you would need to work 822 hours
Answer:
z = 110°
Step-by-step explanation:
Angles z and the one marked 70° form an linear pair, hence are supplementary.
z = 180° -70° = 110°
<h3>Angles where chords cross</h3>
The angle made by two chords is half the sum of the arcs intercepted by those chords. Here, that means ...
70° = 1/2(60° +x) ⇒ x = 140° -60° = 80°
The arc w completes the circle of 360°, so we have ...
w +x +79° +60° = 360° ⇒ w = 360° -219° = 141°
Finally, z is the average of w and 79°:
z = (w +79°)/2 = (141° +79°)/2 = 110° . . . as above
