Hey there!
When we put a number in scientific notation, we want the first number to be at least 1 and less than 10. There must be a digit from 1-9 in the ones place.
With the number 0.000015, we can move the decimal place 5 places to the right and we have 1.5, which is more than one and less than ten.
Because we moved the decimal place 5 places to the right, 1.5 is multiplied by 10 to the power of -5.
The 5 is the number of places the decimal is moved, and the negative sign is because we moved it to the right.
10^(-5) is the same as 0.00001, just for context.
So, 0.000015 meters in scientific notation is 1.5 x 10^(5) meters.
Hope this helps!
8z − 4 = 7z
move 8z to the other side
sign changes from +8z to -8z
8z-8z-4=7z-8z
-4= 7z-8z
-4= -z
mutiply both sides by -1 to get +z
(-4)(-1)= (-z)(-1)
Answer:
z= 4
Answer:
Step-by-step explanation:
arc BE is the same as the interior angle, or 76°
BE = 76 °
we can also find arc CE the same way, b/c we can see that the interior angle is the suppment with 76 or 180-76 = CE or 104°
Now we know all the arcs but arc CD
so use the idea that all the way around the circle is 360°
360 = 76 + 104 + 140 + CD
360 - 76 - 104 - 140 = CD
40 = CD
CD = 40 °
