A
Step-by-step explanation:
First and foremost, we can rule out B and C because they are less than one and would make the hexagon smaller instead of bigger. Now, when we measure the units, we see that it goes up by 2 squares on the graph. So, by process of elimination and measurement, we get the answer of A.
The rate of travel, or speed, is
200 miles
--------------- = 40 mph
5 hours
Recall that distance = rate times time, so that rate = distance / time.
Answer: -14
Step-by-step explanation: Here we're asked to simplify -|-14| so we
start by simplifying the absolute value of -14.
Remember that the absolute value of
any positive or negative integer is positive.
So the absolute value of -14 is 14.
So we write (14) in parenthses like I have just done.
Next, we bring down the negative sign
that was outside the absolute value.
So we're left with -(14) or -14.
Answer:
For A) it is possible that the speed the cat is going over the speed limit
For B) The statement is false as if the error is negative, the speed of the car will be less than the speed limit.
Step-by-step explanation:
Data provided in the question:
Maximum error on a car speedometer = 1.6% = 0.016
Maximum Speed limit on the road = 65 miles per hour
Now,
The error will be ± 1.6%
Now,
When the speedometer reads 64 miles per hour
The possible speed of the car can be
64 miles per hour + Error
= 64 + [0.016 × 64]
= 64 + 1.024
= 65.024 miles per hour
or
The speed can be
64 miles per hour - Error
= 64 - [0.016 × 64]
= 64 - 1.024
= 62.976 miles per hour
Hence,
For A) it is possible that the speed the cat is going over the speed limit
For B) The statement is false as if the error is negative, the speed of the car will be less than the speed limit.
