Answer:
- 7040 yards
- zeros are place holders
Step-by-step explanation:
Each mile is 1760 yards, so 4 of them is ...
4 × 1760 yards = 7040 yards
__
This number is written as a decimal number in a "place value" system, so the position of the digit in the number tells its value.
In order for the 7 to indicate 7 thousand, it needs to be in the "thousands" place in the number. The 0s in the hundreds and units places are called "place holders" because they ensure the other digits appear in their proper places in the number.
__
If it were written in Roman Numerals, it would be 
. In this system, the letter tells its value (and "place" comes into account in XL, which means X is subtracted from L). The system of Roman Numerals has no zeros, and doesn't need them.

Answer:
answer is *** 19.6 ***
Step-by-step explanation:
Answer:
See Below.
Step-by-step explanation:
Please refer to the diagram below.
We are given that O is the center of the circle, and chords MN and RS are intersected a P. OP is the bisector of ∠MPR. And we want to prove that MN = RS.
We will construct segments OK and OJ such that it perpendicularly bisects MN and RS.
Since OP bisects ∠MPR, it follows that:
And since OK and OJ are perpendicular bisectors:
Therefore:
By the Reflexive Property:
Therefore:
By AAS Congruence.
Hence:
By CPCTC.
Recall that congruent chords are equidistant from the center.
Thus, by converse, chords that are equidistant from the center are congruent.
Therefore:
