Answer:

Step-by-step explanation:

<h3>If you are given the interior angle, just subtract that from 180 to get the exterior angle and then use the number of sides = 360 / exterior angle to find the number of sides. it's much easier. the number of sides is equal to 10. the sum of the interior angles is equal to 10 * 144 = 1440 degrees.</h3>

  • n ≤ 606

Step-by-step explanation:

<u>Seven less than the product of a number n and 1/6 is no more than 94, translating:</u>

  • n*1/6 - 7 ≤ 94

<u>Solving for n:</u>

  • n/6  ≤ 94 + 7
  • n/6 ≤ 101
  • n ≤ 101*6
  • n ≤ 606

If KN=29, what is CN?
wel
To find the answer you need to identify what x is.
To find the x first you need to make the equation 6x+11=29.
You then subtract 11 from each side which cancels out the 11 and makes the 29 18. 
You then divide the entire equation by 6 to get the answer x=3. 
You then input x for the CN line equation.
4(3)+1
Thus, your answer should be 13 (D)

A doctor can prescribe one of two drugs to treat a certain disease. Drug A will cure 75% of the cases but has unwanted side effe
Phoenix [80]

The total number of patients experienced unwanted side effects is 48

<u><em>Explanation</em></u>

60 patients are given drug A and drug A has unwanted side effects in 40% of the cases.

So, the number of patients experienced side effects for drug A = 40% of 60 =(0.40*60)= 24

Now 80 patients are given drug B and it has side effects in 30% of the cases.

So, the number of patients experienced side effects for drug B = 30% of 80 =(0.30*80)= 24

So, the total number of patients experienced unwanted side effects = 24+24 =48
