Bicycle Water Bottle Mounts

hellpp me with these math problems!!?

1.) When Joes zips down the country roads on his bicycle, it takes him 40 minutes to go 8 miles. When he drives the car, Javier travels twice as far in two-fifthsthe time. What is Javier’s speed, in miles per hour, when he drives his car?

Speed is distance divided by time. Joes (Jose? Joe?) goes 8 miles in 40 minutes. The problem specifically requests the final answer in miles per hour, so we must convert our time units to hours. We may do this with ratios:

1 hr / 60 min = x hr / 40 min, giving a time of 2/3 hour.

Javier travels twice as far, i.e., 2 * 8 miles or 16 miles, in two-fifths the time, i.e., 2/5 * 2/3 hours, or 4/15 hours. We may now find Javier’s speed by dividing his distance by his time: 16 ÷ 4/15 = 16/1 * 15/4, which is 60 miles per hour.

2. Robert’s equation is y = 3x + 6. Roberta’s equation, when solved for y, becomes y = -3x + 4. Because the two expressions on the right equal the same thing, they must equal each other. This gives an equation of
3x + 6 = -3x + 4, from which you may solve for x.

3. Let us let ra be the radius of bottle a and rb be the radius of bottle b, Va the volume of bottle a, Vb the volume of bottle b, ha the height of bottle a, and hb the height of bottle b.

We know:

Va = π*ra²*ha
Vb = π*rb²*hb
ra = 2*rb
hb = 2*ha

If we take the ratios of the volumes of the two bottles, we get

Vb / Va = (rb²*hb) / (ra²*ha)
= [(1/2*ra)²*2*ha] / (ra²*ha)
= (1/4*ra² *2*ha) / (ra²*ha)
= 1/2 * (ra²*ha) / (ra²*ha)
= 1/2

Therefore, bottle B is only half the volume of bottle A, or conversely, bottle A holds twice as much as bottle B.
