50 because there are 6 sides and 300 roles, if its equal of course. ;)!

A number cube has six sides. The probability of landing on any of the numbers is equal. The theoretical probability of rolling a 6 is 1/6. I expect a 6 to be rolled (1/6)(300), or 50 of 300 times

Subtract 5y ^ 2 - 6y - 11 from 6y ^ 2 + 2y + 5 .
Korvikt [17]

Step-by-step explanation:

(6 {y}^{2}  + 2y + 5) - (5 {y}^{2}    -   6y - 11) \\  = 6 {y}^{2}  + 2y + 5 - 5 {y}^{2}   + 6y  +  11 \\  = 6  {y}^{2}  - 5 {y}^{2}  + 2y + 6y + 5 + 11 \\  =  {y}^{2}  + 8y + 16

2(5x+5) + 9(x-10) + 9-squared
Sholpan [36]

Step-by-step explanation:

We'll use BODMAS to solve this

Open the brackets :

  1. 2(5x+5)+9(x-10)+9sq = 10x+10+9x-90+81
  2. Then we arrange them accordingly :10x+9x+10-90+81
  3. We then calculate :19x+10-90+81
  4. BODMAS :19x+91-90 = 19x+1
  5. ANSWER :19x+1

WORTH 20. HELP ASAP.

Plug it into a graphing calculator and see where the function crosses the x-axis. Since it’s a quadratic it will cross it two times but one of the answers is negative—obviously it wouldn’t take negative second to hit the ground. It should take 9 seconds for the object to hit the ground.
