Answer:

7. V = pi(r)^2(h)

   V = pi(7)^2(20)

   V = 3078.76

8. Same formula as 7.

V = 502.65

10. Same formula again

V = 62.83

11. V = 4/3*pi(r)^3

    V = 4/3*pi(6)^3

    V = 904.78

1.theoretical is not counting the results of the experimentssince there are an equal number of red and black and red, the probblity (theoretical) of picking a black one is 1/3
experimental=number of outcomes happened/total number of tests4 times black, 4 tests, so 4/4 or 100%=experimental proablity

2. experimental considered previous trials and theoretical did not

3. theoretical=(1/4) the trials don't influence each other so1/(4*4)=1/16

Please answer number 1 and 2 with ABC or D
Free_Kalibri [48]

Answer:

1. (a) a+b=86

2. (c) 5.99a+9.99b≤600

Step-by-step explanation:

1.

a = amount of 16gb memory sticks

b = amount of 21gb memory sticks

Gary is buying a memory sticks for each of the 86 teachers. Therefore the total sum of both 16gb and 32gb memory sticks should equal 86:

a+b=86

2.

a = amount of 16gb memory sticks

b = amount of 21gb memory sticks

Each 16gb memory stick cost $5.99, and each 32gb one costs $9.99. Therefore...

5.99a = total cost of 16gb memory sticks

9.99b = total cost of 32gb memory sticks

Gary has to spent an amount less than or equal to $600. Therefore, the total sum of the costs of both 16gb and 32gb memory sticks should be less than or equal to 600:

5.99a+9.99b≤600

What’s the answer for this question?
loris [4]
Your answer is 16 because you have to multiply b and c but it has to be squared and then you subtract 400 by 144 and get 256 and the square root of that is 16
