Answer:
Step-by-step explanation:
if you have negative numbers of x (this means negative meters) then the equation transform them into negative yards.
then replace y by 40yd in the equation like
40 = 1.09x
x = 40/1.09 = 36.7 meters
so in a 40yd race, there are 36.7 meters.
Answer:
18 centimeters
Step-by-step explanation:
Divide the circumference by π, or 3.14 for an estimation. The result is the circle's diameter.
Divide the diameter by 2.
There you go, you found the circle's radius
6 semicircles = 3 circles
The formula of the area of a equilateral triangle:

We have a = |AE| = 3cm. Substitute:

The formula of the area of a circle:

We have 2r = |AE| =3cm → r = 1.5cm. Substitute:

The area of the figure:

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.
The answer to This question should be 25
