Answer:

<em>12.5w = 419.38</em>

<em>and</em>

<em>15.5w = 419.38</em>

Step-by-step explanation:

find the total cost of all the computer parts.

= 259.99 + 2* 39.95 + 79.49 = $419.38

Shana will save $12.50 per week and Marie will save $15.50

per week

therefore we can create two inequalities

<h2><u> Shana:</u></h2>

12.50 * w = 419.38

<em>12.5w = 419.38</em>

w = 419.38/12.5

w = 33.5504

<h2><u>Marie</u></h2>

15.50*w = 419.38

<em>15.5w = 419.38</em>

w = 419.38/15.5

w =27.0568

Use the quadratic formula to solve the equation. If necessary, round to the nearest hundredth.
Keith_Richards [23]

Answer:

8.0 seconds to the nearest tenth,

Step-by-step explanation:

h=-16t^2 +vt + c.

-16t^2 + 116t + 101 = 0

t =  [ -116 + /- √(116^2 - 4*-16*101) ] / (-32)

t = (-116 +/- √19920) / (-32)

t = -0.79, 8.036  (we ignore the negative root)

The time in flight = 8.036 seconds.
