Paul Revere had to travel 3.5 miles to Boston from Charlestown by boat. From Charlestown to Lexington he was able to ride a horse that traveled at a rate of 1/8 mile per minute. His total distance traveled y is the sum of the distance to Charlestown and the distance from Charlestown to Lexington. Write a linear equation that could be used to find the distance y Paul Revere traveled in x minutes

Ответ:
y = 3.5 + (1/8)x
Step-by-step explanation:
Speed is the ratio of total distance traveled to the total time taken. It is given by the formula:
Speed = distance / time.
The distance Paul Revere traveled from Charlestown to Boston is 3.5 miles.
Paul Revere also traveled from Boston to Lexington by horse at a rate of 1/8 mile per minute. If he traveled for x minutes, the distance covered can be gotten by:
Speed = distance / time
1/8 = distance / x
distance = (1/8)x miles.
y = sum of the distance to Charlestown and the distance from Charlestown to Lexington
y = 3.5 + (1/8)x
Ответ:
3.62 units
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relation between the side adjacent to the angle and the hypotenuse:
Cos = Adjacent/Hypotenuse
cos(34°) = AB/AC
AC = AB/cos(34°) = 3/cos(34°) ≈ 3.619 ≈ 3.62 . . . units
For right triangle ABC with A an angle of 34°, AB of length 3, and AC the hypotenuse.
