Answer:

jackie rode his bike 30 miles. Only if he stayed at a consistent rate while riding his bike. this is because if he only biked for an hour he simply would have biked 20 but since its a half hour you just divide 20 by 2 which gives you 10 simple :) a equation for this could be 20+x=1 1/2

Answer:

30 miles.

Step-by-step explanation:

To calculate distance traveled, you multiply the miles per hour by the number of miles. In this problem, it is 20 times 1.5 or 20 times 1 1/2. This equals 30 miles per hour.

What is the answer (6-1+7) =
sdas [7]

Answer:

12

Step-by-step explanation:

You do what's in parentheses first, but everything is in parentheses so it's pretty much ineffective. In PEMDAS, addition and subtraction are coupled so you do them left to right. 6-1 is 5 and 5+7 is 12.

A curcular track is 1/4 completing each mile every 1/15 mile
dsp73

Answer:

s = 3.75 miles/hour

Step-by-step explanation:

Distance covered = 1/4 of a mile

Time taken = 1/15 of an hour

We need to find the speed of the track. We know that,

s=\dfrac{d}{t}\\\\=\dfrac{\dfrac{1}{4}}{\dfrac{1}{15}}\\\\=3.75\ mi/h

So, the required speed is 3.75 miles/hour.

ki77a [65]

Answer: \frac{\sqrt{3} }{2}

Step-by-step explanation:

To find sin(60), you need to know the unit circle. Sin(60) is the same as sin(π/3). On the unit circle, sin(π/3) is √3/2. We know this because the coordinates are (cos, sin). Sin is the y coordinate.
