Answer: 11.4
Step-by-step explanation:
I did part / whole = % / 100
So x / 76 = 15 / 100
76 x 15 = 1140
1140 ÷ 100 = 11.4
Answer:
x=10
Step-by-step explanation:
5/8x - 11/2 = 3/4
Multiply each side by 8 to clear the fractions
8(5/8x - 11/2 = 3/4)
5x - 44 = 6
Add 44 to each side
5x-44+4= 6+4
5x= 50
Divide by 5
5x/5 = 50/5
x =10

b. 
Step-by-step explanation:
The initial value problem is given as:
Applying laplace transformation on the expression 
to get ![L[{y+y'} ]= L[{7 + \delta (t-3)}]](https://tex.z-dn.net/?f=L%5B%7By%2By%27%7D%20%5D%3D%20L%5B%7B7%20%2B%20%5Cdelta%20%28t-3%29%7D%5D)

Recall that:
![y(t) = 7 [1-e^{-t} ] + L^{-1} [\dfrac{e^{-3s}}{s+1}]](https://tex.z-dn.net/?f=y%28t%29%20%3D%207%20%5B1-e%5E%7B-t%7D%20%5D%20%2B%20L%5E%7B-1%7D%20%5B%5Cdfrac%7Be%5E%7B-3s%7D%7D%7Bs%2B1%7D%5D)
Then
Answer:
1. A point you can't move at all, a line you can only move back and forth in the same direction. Yes it is accurate for its characteristics because points and lines have no set definition for them
2. When you are on a point you can not travel at all in any direction while staying on that point. That means you have zero options to travel in. That is why it is said you have zero dimensions.
3. Normal space refers 3 dimensional space that extends beyond the three dimensions of length, width, and height.
4. If you can move backward, forwards, up and down in two different directions it is considered two dimensional. The two dimensional figure is considered a plane. For example, if you took a piece of paper that extended forever in every direction, that in a geometric a sense, is a plane. The piece of paper itself is itself, finite, and you could call the piece of paper a plane segment because it is a segment of an entire plane.
