Step-by-step explanation:
VW, also know as side X (as shown in image) can be found using the sine. Sin(theta)=opposite/hypotenuse. In this case, theta is 31 degrees and the hypotenuse is 31 feet. Plugging in all known values, we would have sin(31)=x/31. Rearrange the equation and isolate X on one side. Then use a calculator to find the answer. Good luck!
Let C(x) be the function which calculates the total cost of making x skirts.
There is going to be a fixed constant, 250, to which we will add 15$ per x skirts.
So C(x)=250+15x
Answer: 250+15x
Answer:
The answer is: 
Step-by-step explanation:
If we add the angles inside a triangle, we must have 
. So we have an 
angle and an 
angle, their sum is 
, so the missing angle must be 
Answer:
- 24 ounces of solution B
- 16 ounces of solution A
Step-by-step explanation:
The largest contributor of salt to the mix is the 45% solution (B), so we'll let our variable (b) represent the quantity of that. The total amount desired is 40 ounces, so the quantity of solution A is (40-b) ounces. Then the amount of salt in the mix is ...
0.45b +0.20(40-b) = 0.35(40)
Simplifying and subtracting 0.20(40), we get ...
0.25b = 0.15(40)
b = 40(.15/.25) = 24
(40-b) = 16
The scientist should use 24 ounces of Solution B and 16 ounces of Solution A.
