Answer:

30 feet

Step-by-step explanation:

Hello!

Half an hour is 30 minutes, so that means we are asked to find h(30).

Solve for h(30):

  • h(30) = 150 - 4(30)         \implies Substitute 30 for t
  • h(30) = 150 - 120           \implies  Simplify
  • h(30) = 30

The person would be 30 feet above the ground in half an hour.

Answer:

30 ft

Step-by-step explanation:

Half an hour is equivalent to 30 minutes.

Thus, h(t) = 150 - 4t becomes h(30 min) = 150 ft - 4(ft/min)(30 min) = 30 ft

Order these numbers from least to greatest.<br> 3.195, 67/20, 3.19, 3 1/3
galina1969 [7]
The numbers from least to greatest are 3.19, 3.195, 3 1/3, and 67/20. This is because 67/20 is equivalent to 3.35 in decimal form, which is greater than all of the other numbers, including 3 1/3, which is 3.3333.

Can someone please help me with this ASAP!! (will mark as brainliest if correct)
sattari [20]

Answer:

P = 6x-2

x = 14

Step-by-step explanation:

To find the perimeter, we add the sides

P = 4x-8 + 3-2x + 5x+3

Combine like terms

P = 4x-3x+5x  -8+3+3

  = 6x -2

Now we know the perimeter

82 = 6x-2

Add 2 to each side

82+2 = 6x-2+2

84 = 6x

Divide each side by 6

84/6 = 6x/6

14=x
