Answer:
175 miles
Step-by-step explanation:
Hillary has travelled
320 + 350 = 670 miles
in the first two weeks.
Therefore, Hillary starts with 670 miles and needs to add a certain number of miles "x" to get 845 in total.
670 + x = 845
And if we subtract 670 from both sides:
x = 845 - 670 = 175
175 miles
Answer:
C
Step-by-step explanation:
Swing an arc the length of the radius from the point on the circle.
This is a problem for which you will have to use the Pythagorean theorem.
The Pythagorean theorem states that:
x^2 + y^2 = h^2
where x and y are the legs, and h is the hypotenuse.
Let h = 20 ft, and x = 16
16^2 + y^2 = 20^2
Now, solve for y.
256 + y^2 = 400.
256 - 256 + y^2 = 400 - 256
y^2 = 144
y = 12
The length of the other leg is 12 feet.
