Answer:
It’s already in expanded form.
Step-by-step explanation:
The original number is 54,025.
Expanded form is when you kind of “take apart” a number. You basically break it apart.
Example: Write 24,382 in expanded form.
Correct way: 20,000 + 4,000 + 300 + 80 + 2
Incorrect way: 2 + 4 + 3 + 8 + 2 (that would equal 19, which is way off from 24,382).

This is simple pythagoras, its just a²+b²=c². First you find the hypotenuse, which is 97; now you have the equation: x²+72²=97²
x²=9409-5184
x= √4225
x=65
the answer is 65m
Answer:
There are 0.70km in 765 yards.
Step-by-step explanation:
This is a problem of conversion of units, that can be solved by multiple rule of three's.
The first step is converting 765 yards to feet. We have that each yard has 3 feet, so
1 yard- 3 feet
765 yards - x feet
x = 765*3
x = 2295
So, in 765 yards there are 2295 feet.
Now, we have to convert 2295 feet to miles. Each mile has 5280 feet, so:
1 miles - 5280 feet
x miles - 2295 feet
5280x = 2295
x = 0.435 miles
So, in 765 yards there are 2295 feet which is 0.435 miles
Now, the final step is converting from miles to kilometers. Each km has 0.621 miles, so:
1km - 0.621 miles
xkm - 0.435 miles
0.621x = 0.435
x = 0.70km
So, there are 0.70km in 765 yards.
