Compare the two fractions
Her rate of speed is 12.075 miles an hour
Answer:
x = 19
Step-by-step explanation:
x = the number
The words translate into algebra as
4x + 25 = 6x - 13
Solve for x.
25 + 13 = 6x - 4x
38 = 2x
x = 19

Angles of rotation that would not map the shape on itself
Side of a nonagon is:
and a complete rotation is:
To start with, we calculate a possible angle of each rotation:
This is calculated by dividing the complete rotation by number of sides
The question lacks option; so, it's difficult to give a specific answer.
However, I'll give a generalized answer
For the nonagon to map on itself, the angle must be a multiple of the calculated angle of rotation (40)
i.e.
<em>Any angle different from the above listed angles (or any other multiple of 40 not listed above) answers the question.</em>
These statistics are impossible: all students who ride bike and use crossing guard ride a bike, so the proportion of students who ride a bike and use the crossing guard must be less than or equal to the proportion of students who ride a bike. This is not true in the given stats; 0.12 > 0.1
