Step-by-step explanation: the distance is the time spent times 60 miles per hour.
The probability of a blue marble falling out is 2/20 or 1/10
8+2+7+3=20 and 8+7+3=18 so the chance of red yellow or green marble is 18/20 or 9/10
Answer: ![-\frac{1}{3}](https://tex.z-dn.net/?f=-%5Cfrac%7B1%7D%7B3%7D)
Step-by-step explanation:
The equation used to find the slope of the line with two give points and is:
![m=\frac{Y2 - Y1}{X2 - X1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7BY2%20-%20Y1%7D%7BX2%20-%20X1%7D)
If the points are and
, we only have to substitute them in the equation:
![m=\frac{4 - 5}{2 - (-1)}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B4%20-%205%7D%7B2%20-%20%28-1%29%7D)
![m=\frac{-1}{2+1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-1%7D%7B2%2B1%7D)
Hence, <u>the slope is</u>:
![m=-\frac{1}{3}](https://tex.z-dn.net/?f=m%3D-%5Cfrac%7B1%7D%7B3%7D)
Answer:
Arc length of arc BC is 6.98 units or roughly 7 units.
Step-by-step explanation:
First recall that the formula for the circumference of a circle is C = 2πr, where r is the radius. Here the radius is 4 units. so the circumference of the (entire) circle is C = 2π(4 units) = 8π units.
The central angle for the arc shown in yellow is 100 degrees. The length of this arc is a fraction of C as found earlier:
100
------- * 8π units = 800π/360 units, or 6.98 units (about 7 units).
360
Arc length of arc BC is 6.98 units or roughly 7 units.
