I'm sure it is 180 degrees
Step-by-step explanation:
step 1. 250(3/5) = 50(3) = 150.
step 2. She spent $150 for the coat.
Answer:
A midocean ridge or midoceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.

Answer:
![P(x) = 150000](https://tex.z-dn.net/?f=P%28x%29%20%3D%20150000)
![Slope = 0](https://tex.z-dn.net/?f=Slope%20%3D%200)
Step-by-step explanation:
Given
![Cost = 150000](https://tex.z-dn.net/?f=Cost%20%3D%20150000)
Solving (a): The cost function:
From the given parameter, it shows that the number of floor has no effect on the floors.
So, represent the floors with x.
The cost function is:
![P(x) = 150000](https://tex.z-dn.net/?f=P%28x%29%20%3D%20150000)
Solving (b): The slope and its interpretation
A function is represented as:
![f(x) = b + mx](https://tex.z-dn.net/?f=f%28x%29%20%3D%20b%20%2B%20mx)
Where:
![m=slope](https://tex.z-dn.net/?f=m%3Dslope)
By comparing:
to ![P(x) = 150000](https://tex.z-dn.net/?f=P%28x%29%20%3D%20150000)
![m = 0](https://tex.z-dn.net/?f=m%20%3D%200)
So:
![Slope = 0](https://tex.z-dn.net/?f=Slope%20%3D%200)
<em>What it means is that, no matter the number of floors, the cost remains unchanged.</em>
Answer:
x + y = 4
Step-by-step explanation:
Given that, (x + iy)(1 - 3i) = 10, then we have to calculate x + y.
Now, (x + iy)(1 - 3i) = 10
⇒ x(1 - 3i) + iy(1 - 3i) = 10
⇒ x - 3xi + iy - 3yi² = 10
⇒ (x + 3y) + i(y - 3x) = 10
Now, comparing the real and imaginary part of both sides we get,
(x + 3y) = 10 ............. (1) and
y - 3x = 0
⇒ y = 3x ............... (2)
Solving equations (1) and (2) we get
x + 3(3x) = 10
⇒ x = 1
So, y = 3x = 3
Therefore, x + y = 1 + 3 = 4 (Answer)
