**Answer:**

B.) 20 degrees

**Step-by-step explanation:**

We know that the sum of angles in a triangle is equal to 180, so we can say that 80 + 4x + x is equal to 180. This means that 5x is 100 degrees, meaning that x = 20 degrees. The option with this answer is B.).

Part A is found by solving the equation for t

Answer is 1 second

Part B

Rewrites in vertex form Thid gives

-16(t+5/8)^2 + 25/4 -4

= -16(t+5/8)^2 + 2 1/4

Maximum height = 2 1/4 feet Answer

**Answer:**

so I believe we can do 15% of 45, so that is 6.75.

so now we do:

45.00

<u>+ 6.75</u>

<u><em>**51.75 is your answer!**</em></u>

There are 36 possible ways of throwing two dices. The following lists are shown in ordered pair:

(1,1) (1,2) (1,3) (1,4) (1,5) (1,6)

(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)

(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)

(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)

(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)

(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)

a) a pair of 3's

The probability is 1/36 because there is only one pair which is (3,3).

b) any pair

The probability is 6/36 or 1/6 because the number of pairs are (1,1) (2,2) (3,3) (4,4) (5,5) and (6,6).

c) at least one 4

The probability is 10/36 or 5/18 because there would be (4,1) (4,2) (4,3) (4,5) (4,6) (1,4) (2,4) (3,4) (5,4) (6,4) for any combination.

d) a total of 9

The probability is 4/26 or 2/13 because (4,5) (5,4) (3,6) (6,3) are the totals of 9.

5) a total greater than 8

The probability is 10/36 or 5/18. Just find the ordered pair having a sum greater than 8.

Hope this helps.
