6 miles is the entire diameter, divide that by 2 to get your RADIUS.
Answer:
c. sin 30 is positive and sin -30 is negative
Step-by-step explanation:
Picture the unit circle (which is attached). <u>Sine is like the y-coordinate.</u> And -30 and 30 on the unit circle both form equally-sized triangles, but -30 is underneath the x-axis, so it has a <u>negative y-coordinate.</u> 30 is above the x-axis, so it has a <u>positive y-coordinate.</u>
Answer:
The slope is 3/8!
Explanation:
You put your equation in slope-intercept form, that is how you find the slope.
3x-8y=-20
-8y=-3x-20
y=3/8x-20
the fraction is now positive because the numerator and the denominator are both negative so they are changed into positive.

Answer:
1 and 6/35
Step-by-step explanation:
You would want to multiply the denominators with the same number.
5×7
Multiply the numerators as well.
3×7 and 4×5
The fractions you would have now is 21/35 and 20/35, you can now add them up without having difficulties if the denominator is the same number.
You can also change it into decimals but I suggest this strategy.
