kiruha [24]

Answer:

we have:

v  =  \frac{1}{3} \pi \: r {}^{2}h \\  \\  =  > 60\pi =  \frac{1}{3} \pi \: r {}^{2} h \\  \\  <  =  > 180 = r {}^{2} h

=> r²h = 10.18 = 9.20 = 5.36 = 6.30 = 4.45 = 12.15

=> only r²h = 5.36 satisfy the problem

=> h = 5

h = 5 r = 6

h = 5 r = 6=> d = 12

An object is launched straight up into
DiKsa [7]

Answer:

  t ∈ {1, 3}

Step-by-step explanation:

You want to find t such that ...

  h = 27

  27 = -8t^2 +32t +3 . . . . . . substitute the expression for h

  24 = -8t^2 +32t . . . . . . . . . subtract 3

  -3 = t^2 -4t . . . . . . . . . . . . . divide by -8

  1 = t^2 -4t +4 = (t -2)^2 . . . . add 4 to complete the square

  ±√1 = t -2 . . . . . . . . . . . . . . take the square root

  t = 2 ± 1 . . . . . . . . . . . . . . . . add 2

  t = 1 or 3

The object is 27 ft off the ground at t = 1 and again at t = 3.

PLEASE HELP IMMEDIATELY!! ITS WITH ORDER OF OPERATIONS AND PEMDAS!!
vodomira [7]

Answer:

1 = 52

2 = 68

3 = 40

4 = 25

Step-by-step explanation:

1 = (4 + 3)^2 + (12 / 4)

7^2 + 3

49 + 3

= 52

2 = (12 x 9 - 7^2) + 9

(108 - 49) + 9

59 + 9

= 68

3 = (30 - 2) / 7 + 6^2

28 / 7 + 36

4 + 36

= 40

4 = (2 x 7 + 4^2) - 5

(14 + 16) - 5

30 - 5

= 25

Hope this helps!! Brainliest plz??
