How many millimeters are in 15 fluid ounces

Helen [10]

There are 443,603 cubic millimeters in 15 fluid ounces.

Because there are 29,573.5 in 1 fluid ounces, so you would just multiply that answer by 15.

Good luck and have a great day Monkeybutt8103!

The height of a football during a punt is modeled by h=-16t^2+60t+3. If the football hits the ground, how long did it stay in th

weqwewe [10]

"how long..." is asking for time (t). "The amount of time spent in the air" is the time from when the ball was kicked (0 seconds) to the time it landed on the ground. Need to find the x-intercepts (one will be negative which will be invalid). You can do this by factoring ... <em>or by using the quadratic formula.</em> With the equation you provided, it is not factorable, so you must use the quadratic formula.

h = -16t² + 60t + 3

a=-16 b=60 c=3

$t = \frac{-b +/- \sqrt{b^{2}-4ac } }{2a}$

$t = \frac{-60 +/- \sqrt{60^{2}-4(-16)(3) } }{2(-16)}$

$t = \frac{-60 +/- \sqrt{3600 + 192} }{-32}$

$t = \frac{-60 +/- \sqrt{3792} }{-32}$

$t = \frac{-60 +/- 61.6}{-32}$

$t = \frac{-60 + 61.6}{-32}$ or $t = \frac{-60 - 61.6}{-32}$

$t = \frac{1.6}{-32}$ or $t = \frac{-121.6}{-32}$

t = -0.05 or t = 3.8 <em>disregard the negative</em>

Answer: 3.8 seconds

Serjik [45]

Answer:

86362600

Step-by-step explanation:

We want to round to the hundreds place

We look at the 7 in the tens place. Since it is 5 or greater we round up

86,362,575 round to 86362600
