Let r = usual driving rate
let t = usual driving time
We need to figure out t
The distance she covers in her usual time at her usual rate is r*t
The distance she covers in her new time at her new rate is:
(1+t)*((2/3)r)
Set this equal to each other and solve for t.
rt = (2/3)r + (2/3)rt
(1/3)rt = (2/3)r
(1/3)t = (2/3)
t = 2
So her usual time is 2 hours. (There's probably a faster way to do this)
Answer:
3L Lemon-lime soda, 1.5 P Sherbert, 4 1/2 Cups of Ice
Step-by-step explanation:Divide everything by 2, then multiply by 1.5
Answer:
Proof for
Step-by-step explanation:
We are given that a, n, b, r and k are integers.
Also,
Since k divides a and b, we can write,
a = rk and b = sk, where r and s are integers.
Now, we have to prove that k divides r as well that is
Putting value of a and b in the equation, we get:
Since, (r-sn) is an integer, k divides r.
Answer:
4feet and 5 inches is 53 inches converted to feet
Answer:
39 degrees
Step-by-step explanation:
Subtract 90 (for the right angle) and 51 (the given angle) from 180, since all angles in a triangle add up to 180.
180-90-51 = 39
