<span>The dot product here is 10(9) + 6(5)=120
so the vectors are not orthogonal
</span><span>u.v = |u| x |v| cos (theta) ; theta is the angle between them
we know from above that u.v = 120
|u| = sqrt[10^2+6^2]=11.66
|v| = sqrt[9^2+5^2]=10.29
so we know:
theta =cos^-1 120/(11.66x10.29)
so theta = 25 degrees</span><span>

Answer:
27 servings
Step-by-step explanation:
You must calculate the number of servings for each type of food and then add them. To calculate the number of servings, divide the amount of each food by the size of its serving.
Tuna: 5 / 1/2 = 5 * 2 = 10 servings
Chicken Salad: 2 / 1/4 = 2 * 4 = 8 servings
Egg salad: 3 / 1/3 = 3 * 3 = 9 servings
Total number of servings = 10 + 8 + 9 = 27
Answer: 27 servings
Hello! :)
To solve your equation, we will first simplify both sides of the equation
-7 = -1 + x/3
-7 = -1 + 1/3x
-7 = 1/3x - 1
Next, we will flip the equation
1/3x - 1 = -7
Third, we will add 1 to both sides
1/3x - 1 + 1 = -7 + 1
1/3x = -6
Last, we will Multiply both sides by 3
3 * (1/3x) = (3) * (-6)
x = -18 (ANSWER)
That means -18 is you answer
