In a race, a bicyclist travels 3/4 of a mile in 1/4 hour. Determine the unit rate for the speed in miles per hour.
5/2 miles per hour
(3/4÷1/4)=3 miles per hour☆☆☆☆☆☆☆
41/4 miles per hour
4 miles per hour
Answer:
A. 3.66 feet
Step-by-step explanation:
Using trigonometry, we know that ...
BC = DC·tan(30°)
AC = DC·tan(45°)
AB = AC -BC = DC(tan(45°) -tan(30°))
AB = 5√3·(1 -√3/3) = 5(√3 -1)
AB ≈ 3.66 . . . feet
The answer would be 180 because the sum of the exterior angles would equal 360 and 360 divided by 120 equals 3 so that means there are 3 sides. Next you find out how much the interior angle is worth by subtracting it from 180 because they're supplementary you would find that the interior angle is equal to 60 degrees then multiply 60 degrees by how many sides there are (3) which equals 180 degrees.
Answer:
Step-by-step explanation:
Given is a Laplace transform of f(t) as
Let
Solving we get 
Solving B=0=D
Hence we have
f(t) = inverse Laplace of
![\frac{1}{7}[ \frac{s}{(s^2+9)}-\frac{s}{(s^2+16)}]](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B7%7D%5B%20%5Cfrac%7Bs%7D%7B%28s%5E2%2B9%29%7D-%5Cfrac%7Bs%7D%7B%28s%5E2%2B16%29%7D%5D)
=
You would know 4×5=20 so just add 2 more zeroes cause there is a zero in 40 and in 50
hope this is what you're looking for and made sense
