Answer:
x=25°, y=18°
Step-by-step explanation:
Solved! Here is the explanation. As we have supplementary angles, we have a total of 180° of angles. Angle BXD is a right angle, so 2x+40°=90°. 2x=50°, and then we have x=25°. Now, to figure out y, we have to look at angle BXA. In this case, 5y=90°. y=18°. So, x=25° and y=18°. Hope this explanation helps!
Answer:
To produce 400 gallons of a chemical, it costs 700 dollars.
Step-by-step explanation:
We have that:
The cost, C (in dollars) to produce g gallons of a chemical can be expressed as C=f(g).
The interpretation is:
To produce g gallons of a chemical it costs C dollars.
So
f(400)=700
This means that to produce 400 gallons of a chemical, it costs 700 dollars.
Answer:

Step-by-step explanation:
Shown is one-fourth of a circle. Also, according to the picture, the radius is 28 meters.
The area for a whole circle is
.
Using that information, we can find the area as if the circle was whole instead of just the fourth.

Now that we know the area of the whole circle, we just have to divide it by four to find the area of the fourth of the circle.

That means that the area of the shape shown is
.
