Arrange the equations in the correct sequence to rewrite the formula for displacement, d = vt—1/2at^2 to find a. In the formula,
Murljashka [212]

Answer:

a = \frac{2(vt-d)}{t^{2} }

Step-by-step explanation:

Given the formula for calculating the displacement of a body as shown below;

d = vt - \frac{1}{2} at^{2}

d = displacement

v = final velocity

a = acceleration

t = time

To make the acceleration a the subject of the formula, the followin steps must be taken;

Step 1: Subtract vt from both sides of the equation

d-vt = vt-vt-\frac{1}{2}at^{2} \\ d-vt = -\frac{1}{2}at^{2}\\2(d-vt) = -at^{2}

Step 2: Divide both sides by t²

\frac{2(d-vt)}{t^{2} } = \frac{-at^{2} }{t^{2} } \\a = \frac{-2(d-vt)}{t^{2} }

a = \frac{2(vt-d)}{t^{2} }

AnnZ [28]

Answer: C. 10 + 2h = 30

Step-by-step explanation:

  1. A does not make sense because the phone billing company would not be cutting off the money they earn while Jeremiah is on a call with someone.
  2. B does not make sense because the phone billing company would be charging Jeremiah a higher amount than the amount he uses while speaking on the phone.
  3. C makes sense because the phone billing company charges Jeremiah the total amount of his phone and $2 per hour he is on a phone call with someone.
  4. D does not make sense because the total is 30 not h.

If collecte 63 cans which is 21%. How many cans are 46%. And how many is 33% ?
EleoNora [17]
If 63 cand are 21% we must find out what 1% is
To do that we must divide 63 by 21
63/21 = 3
So 1%=3 cans
To find out what a percentage equals we must times it by 3
46 * 3 =138 cans
33*3 = 99 cans
Hope this helps :)
