Answer:
1/56
Step-by-step explanation:
P( bear is first) = bear/ total = 1/8
Then there are 7 animals left
P( zebra is 2nd) = zebra /total = 1/7
P( bear, then zebra) = 1/8 * 1/7 = 1/56
Answer:
C=5
Step-by-step explanation:
3^ + 4^2 = 25
and the square root of 25 is 5 therefore C=5
Simplify the integrands by polynomial division.


Now computing the integrals is trivial.
5.

where we use the power rule,

and a substitution to integrate the last term,

8.

using the same approach as above.
Step-by-step explanation:
lets take a look....
In order to find the perimeter of a triangle you have to get the sum of all sides. In other words,
Blue triangle:

Red triangle:

Difference:

Let the two numbers be x and x + 40, then
x + x + 40 = 180
2x = 180 - 40 = 140
x = 140/2 = 70
Therefore, the measures of the two angles are 70° and 70 + 40 = 110°
