Answer:
222 fence posts
Step-by-step explanation:
Since the log is 20 m long, correct to the nearest metre and has to be cut into fence posts which must be 90 cm long, correct to the nearest 10 centimetres, there can be x fence posts 90 cm long.
So, we have x × 90 cm = 20 m
x × 0.9 m = 20 m
x = 20 m/0.9 m
x = 222.22
x ≅ 222 fence posts
So, the largest number of fence posts that can possibly be cut from the log is 222 fence posts.
It is given in the question that
A projectile is fired at 657 mi/hr. how fast is that in meters per second? use the conversion factor 1 mile = 1610 m.
So we need to convert miles per hour to meters per second.
And it is given that 1 mile equals to 1610 meters and 1 hour equal to 3600 seconds.
So we will get
<em><u>Answer:</u></em>
(7, -5)
<em><u>Step-by-step explanation:</u></em>
We can see the dot, is 7 units to the right of the y axis, and 5 down from the x-axis. We then can create the coordinates because we know where it is:
If it is on the right side of the y-axis, it is positive. If it is below the x-axis, it is negative so:
(7, -5) would be the coordinate point
