Answer:
12
Step-by-step explanation:
10 - 1/2 x = 12-4/3x
60 - 3x = 72-2x
-12 = - x
1/2 * 3 = 1.5 oz of meatloaf
3/4 * 3 = 2.25 oz of mashed potatoes
1/3 * 2 = 0.67 oz of green beans
1.5 + 2.25 + 0.67 = 4.42
Stacy consumed approximately 4.42 oz of solid food.
Answer:
8² = 4² + 5² - 2(4)(5) cos(P)
which is the third option
Explanation:
The general rule of cosine is:
a² = b² + c² - 2bc*cos(A)
In our triangle:
a is substituted by p = 8 cm
b is substituted by n = 4 cm
c is substituted by m = 5 cm
A is substituted by P which we want to find
Replace the variables in the general equation with the givens as follows:
p² = n² + m² - 2mn*cos(P)
8² = 4² + 5² - 2(4)(5) cos(P)
Hope this helps :)
