2 x 2 x 2 equals 8. Cubed means to multiply 2 by 2 3 times, 2 x 2 = 4, x 2 = 8.
Answer:Ratio in miles per hour is 12 miles per hour.
Distance travelled is 60miles
Step-by-step explanation:
Speed=distance/time taken
24/2=12miles per hour
Therefore, distance travelled in 5 hours is 12*5=60miles
Answer:
The equation of the line would be y = 5x - 28
Step-by-step explanation:
First, we need to know that perpendicular lines have opposite and reciprocal slopes. Give that information, we know that the new line will be the reciprocal and opposite of -1/5. This would be 5. Now that we have that information, we can use it along with a point to fill in the point-slope form of the equation.
y - y1 = m(x - x1)
y - 2 = 5(x - 6)
Then we must solve for y.
y - 2 = 5(x - 6)
y - 2 = 5x - 30
y = 5x - 28
When y=21 and x=9
21/9
which means that to go from x to y, you multiply x by 2.33
2.33x=y
2.33x=52.5
divide both sides by 2.33
x=22.53 (when rounded)
so when y=52.5, x=22.53
