Answer:
For every 1 inch on the drawing, it's 3 feet in real life.
Step-by-step explanation:
First, consider the length. The length is 6 inches on the drawing, while in actuality it is 18 feet. So every 6 inches represents 18 feet. Let's make a ratio; 6 : 18. To simplify it, divide both sides by 6; 6 : 18 = 1 : 3.
For every 1 inch on the drawing, it's 3 feet in real life.
I think I can help with this prob i did this a few weeks back
Answer:
Jo started decelerating at the 10th minute
His average speed for the last 30 minutes of the journey is 4/30 km/minute
Step-by-step explanation:
To get what Jo did at 10 minute, we look at the graph.
At the 10th minute, we can see that we have a sharp turn from the top to the zero position at the 20th minute
so we can say that Jo started deceleration at the 10th minute
For the last 30 minutes of the journey, he travelled a distance of 4km
So, mathematically, his average speed will be;
Distance/ time = 4km/30 minutes = 4/30 km/minute
121 is the answer. you divide 22 by two and then raise it to the power of two
-2x^3 = 0
solving for x you divide both sides by -2
x^3 = 0
Now take the cube root of each side
x = cube root of zero
x = 0
It has 1 root.
The root is zero
