-5 because a negative plus a negative is a positive this is why it is the right answer
a). 0.45 with a line over the 45 means 0.45454545454545... forever.
It's equivalent to 45/99 which is <em>5/11</em> .
b). 0.45 with a line over the 5 means 0.455555555... forever.
It's equivalent to (0.4 + 0.555555.../10)
The 0.4 part is 4/10
The 0.5555555555.../10 part is 5/90 .
(4/10) + (5/90) = <em>41/90 </em>
c). 0.45 means 45/100 . That's <em> 9/20</em> .

Answer:
help me plzz
Step-by-step explanation:
The velocity of a particle moving along the x-axis is v(t) = cos(2t), with t measured in minutes and v(t) measured in feet per minute. To the nearest foot find the total distance travelled by the particle from t = 0 to t = π minutes
Answer:
299 miles per hour
Step-by-step explanation:
![v=\frac{234}{\sqrt[3]{\frac{p}{w}}}](https://tex.z-dn.net/?f=v%3D%5Cfrac%7B234%7D%7B%5Csqrt%5B3%5D%7B%5Cfrac%7Bp%7D%7Bw%7D%7D%7D)
![v=\frac{234}{\sqrt[3]{\frac{1311}{2744}}}](https://tex.z-dn.net/?f=v%3D%5Cfrac%7B234%7D%7B%5Csqrt%5B3%5D%7B%5Cfrac%7B1311%7D%7B2744%7D%7D%7D)
Therefore, the velocity of the car at the end of a drag race is 299 miles per hour
