60%
Solve by creating a proportion
27/45 = x/100
Cross multiply to get 2700=45x
Divide 45 on both sides to get x=60
The vertex would be (5,-23)

Answer:
(t, u, w) = (1, -2, -2)
Step-by-step explanation:
A graphing calculator makes short work of this, giving the solution as ...
(t, u, w) = (1, -2, -2)
__
There are many ways to solve this "by hand." Here's one of them.
Add the first and third equations. Their sum is ...
-3t +4w = -11 . . . . . [eq4]
Add this to twice the second equation. That sum is ...
(-3t +4w) +2(-4t -2w) = (-11) +2(0)
-11t = -11
t = 1
Substituting this into the second equation gives ...
-4(1) -2w = 0
w +2 = 0 . . . . divide by -2
w = -2 . . . . add -2
Substituting for t in the third equation lets us find u.
2(1) -2u = 6
-1 +u = -3 . . . . . divide by -2
u = -2 . . . . add 1
The solution is (t, u, w) = (1, -2, -2).
Thank you for posting your question here at brainly. To answer the above question,
First calculate the Joules (work done by Alexander), divide by 4.184 to get calories and then divide by 1000 to get kilocalories or Calories.
<span>201 lbs will be 90 kgs approx. And work done will be mgh = 90 x 10 x 5220 kg.m Double that for coming down.</span>
there is an error because -9 x 1 = -9 not -1. But I would assume that you multiply -9×-1 and then -9×-2 ect.
