That's "5 to the negative seventh power," and is equal to
1 1
---------- = --------- . I would accept "1/(5^7)" as correct.
5^7 78125
Answer:
B
Step-by-step explanation:
The SA of a cone is A=pi*r^2+pi*r*s
So instead of pi*5^2, it should be pi*3*5 (5 is the length of the slant).
2x+5y=21, x+y=3
y=3-x
2x+5y=21
2x+5(3-x) =21
2x+15-5x=21
2x-5x+15=21
-3x+15=21
-3x=21-15
-x=6/3
-x=2
x=-2
Answer:
'16' is the answer.
Step-by-step explanation:
So, 6=x+2 divided by 3. In this case, we can multiply 6 and 3 which makes
18 = x+2. We substract 2 from 18 and the answer is 16. If you don't understand anything, you can ask by leaving a comment below. Thanks.
16+2 = 18/3 = 6
Standard for would be 6,670,404,013.19
