A runner hopes to complete the 10,000m run in less than 30 minutes. After exactly 27 minutes, there are still 1100m to go. The runner must then accelerate at 0.20 m/s^2 for how many seconds in order to achieve the desired time? I get 80.9 but I know that the answer is 3.1 seco...

Could someone work this out for me? Someone says the answer is 2.34 x 10^-6 but I think it's 2.34 x 10^-4. 2 x 10^-3 = 3 x 10^8 x 1/6 x pi x d Solving for d. Sorry it's kinda messy.
How would one determine the percent uncertainty in theta and in sin of theta for the following: 1) theta = 15.0 degrees +/- 0.5 degrees 2) theta = 75.0 degrees +/- 0.5 degrees I'm not sure whether I divide or use some kind of formula.
So, would that make it 8.76*10^-2? If so, what would the units be?
An average family of four uses roughly 1200 liters (300 gallons) of water per day. (One liter = 1000 cm^3.) How much depth would a lake lose per year if it uniformly covered an area of 50 square kilometers and supplied a local town with a population of 40,000 people? Consider ...
GPS can be used to determine positions with great accuracy. The system works by determining the distance between the observer and each of the several satellites orbiting Earth. If one of the satellites is at a distance of 20,000 km from you, what percent accuracy in the distan...

We are learning about proofs. We drew lines between noncollinear points. Our table showed 2 points >> 1 line segment, 3 point >> 3 line segments, 4 points >> 6 line segments, 5 points >> 10 line seg, 6 points >> 15 line seg. etc. Write an expressi...
3rd graders = x 4th graders = x 5th graders = x + 6 (this is because there are 6 MORE 5th graders than 3rd grade) Make an equation x + x + (x + 6)= 33 group like terms 3x + 6 = 33 subtract 6 from both sides to get x alone 3x = 27 divide both sides by 3 x = 9 PLUG IN 9 for x 3r...
