Here are Recipes for two mixtures of salt and water that is different. Mixture A 4:5
7:8 3/4
9:11 1/4
Mixture b is defined by the equation Y=2.5x where X is the number of teaspoons of salt and y it’s a number of cups of water

If you use 10 cups of water, which mixture will use more salt ?how much more? explain or show your reasoning.

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west

there were a lot of them but the first one to pop up on a google search was bts

=

x=0.8898305 is the answer to that equation
