Answer:
y = 25x - 85
Step-by-step explanation:
Every second (x) that passes by is 25 meters gained, and since she's 85 meters away from the safe distance still, the y intercept is -85.
He ran 4 miles per hour for one hour, which means he ran 4 miles.
He cycled 6 miles at 12 miles per hour, which means he cycled for one half an hour.
His total miles was 4 + 6 = 10 total miles.
His total time was 1 hour + one half an hour = 1.5 hours.
His average speed is total distance divided by total time:
10 / 1.5 = 6 2/3 miles per hour.
Answer:
Angle x is 64 degrees. Angle y is 128.
Step-by-step explanation:
To find angle x:
In an isosceles triangle, the base angles are always congruent (equal). Since we know that one of the base angles is 64, and x is also a base angle, x is 64 degrees as well.
To find angle y:
Again, in an isosceles triangle, the base angles are always congruent. Since we know that one of the base angles is 26, we know that the other base angle is also 26. Then, to find the last angle (y), you use the triangle angle sum theorem which states that all angles in a triangle add up to 180. To figure out angle y, you do 180-26-26 to get 128. So angle y is 128 degrees.
