I did it quickly on a calculator but if you multiply 250 and .7 you get 175, and then subtract 175 from 250 then you get $75, and 75 is your answer
Hope this helps!! :D

The antelope is faster than the wildebeest.
Step-by-step explanation:
The maximum recorded speed for the antelope is 88.5 km/h that it can sustain for almost a kilometer.
The equation for distance a wildebeest can run in t hours is given as ;
d=80t
Assume t=1 hour,d=80*1=80 km then you can say the wildebeest takes 1 hour to cover 80 km and 80 km/h
For a distance of 80 km, the antelope will take how many hours;
Time =Distance/speed =80/88.5 =0.904 hours
The antelope takes less hours to cover the distance, hence the antelope is faster than the wildebeest.

Answer:
the first option 40 degrees
Step-by-step explanation:
the outward angle at the center of the circle between the two tangential points is 220 degrees.
that means that the inward angle between them is
360 - 220 = 140 degrees.
now consider that there is a triangle between the center of the circle, one of the tangential points (it does not matter which one, as the upper and the lower triangles are equal) and the point R.
we know the angle at the tangential point : 90 degrees by definition (otherwise it would not be a tangent).
and we know the angle at center of the circle, which is half of the inward angle
140 / 2 = 70 degrees.
and at point R we have half of the full angle R.
we can calculate that half by using the fact that the sum of all angles in a triangle is always 180 degrees.
180 = 90 + 70 + R/2
180 = 160 + R/2
20 = R/2
R = 40 degrees
