4.  Solve

1430 = 0.55t^2 + 550

1430 - 550 =880 = 0.55t^2

880/0.55 = 1600 = t^2

t= \pm \sqrt{1600} = \pm 40

On the positive answer makes sense.

Answer: Month 40

5. The throw ends when the height is zero (I guess we're ignoring rolling).

0 = -0.02x^2 + x + 6

x = \dfrac{-1 \pm \sqrt{1^2 - 4(6)(-0.02)}}{2(-0.02)}

Only the negative sign for the plus/minus will give a sensible, positive answer:

x = \dfrac{-1 - \sqrt{1^2 - 4(6)(-0.02)}}{2(-0.02)} = 55.4138

Answer: 55.4 feet

Round the fraction 7 4/5 to the nearest whole number
AnnyKZ [126]
The nearest whole number is <span><span>8</span></span>

When we are looking at rounding, we round to the number that our fraction or decimal is located. So, since we are rounding to the nearest whole number, given our original mixed number (7 \frac{4}{5}) our answer will be either 7 or 8.

We can change7 \frac{4}{5} to a decimal to equal 7.8 by multiplying both our denominator and our numerator by 2 since 5 * 2 =10, which would change our fraction to \frac{8}{10} which is the same thing as .8

If we look at 7.8 and want to know if it is closer to 8 or 7, we just remember that when rounding, if it is 5 or above, you round up, anything else, you leave the number in front of it like it is. .8 is above 5 so we round 7 to the whole number 8. So, our answer is 8

Thank you for your question! I hope this helped! Have an amazing day and feel free to let me know if I can help you further! :D
