Answer:
5 hours
Step-by-step explanation:
-150 miles in all
-75 miles per speed
<u>60 mph...</u>
60 miles per hour over 75 miles
75 miles ÷ 60 miles = 1.25 hours
<u>20 mph...</u>
20 miles per hour over 75 miles
75 miles ÷ 20 miles = 3.75 hours
<u>Total hours of driving...</u>
60 mph for 1.25 hours
20 mph for 3.75 hours
3.75 hours + 1.25 hours = 5 hours total
Answer:
The lines are parallel is the will never touch.
Step-by-step explanation:
Answer: Choice A
m = undefined
point (-2,5)
==================================================
Explanation:
The equation x = -2 describes a vertical line in which every point on this line has x coordinate -2. Two points on this line are (-2,0) and (-2,1)
Another point on this line is (-2,5) since this also has x coordinate -2.
------------------
All vertical lines have undefined slope.
Let's pick two points such as (-2,0) and (-2,1) and find the slope through them
m = (y2-y1)/(x2-x1)
m = (1-0)/(-2-(-2))
m = (1-0)/(-2+2)
m = 1/0
m = undefined, since we cannot divide by zero.
The answer is 35
Since they are supplementary they both equal 180 degrees.
(3x+10)+(2x-5)=180
Add them up
5x-5=180
Subtract 5 from both sides
5x=180-5
5x=175
Divide 5 from both sides
x=35.
To find the distance in one turn of the wheel you have to find the circumference of the wheel.
Circumference = pi x d
= 3.14 x 5
= 15.7 cm
therefore the rollerblade wheel will travel 15.7 cm per rotation
