Answer:

I would use a proportion for each ingredient:

Cup sugar

4:10=½:x (10×½)÷4= 1,25 cup sugar

Cup brown sugar:

4:10=¼:x (10×¼)÷4= 0.625 cup brown sugar

Peanut butter

4:10=⅔:x (10×⅔)÷4= 1,65 cup peanut butter

Cup oats

2×¼ = ½

4:10=½:x (10×½)÷4= 1,25 cup oats

Cup milk

4:10=¾:x (10×¾)÷4= 1,875 cup milk

Tsp salt

4:10=1:x (10×1)÷4= 2,5 tsp salt

2 tbsp cocoa

4:10=2:x (10×2)÷4= 5 tbsp cocoa

1 tsp vanilla

4:10=1:x (10×1)÷4= 2,5 tsp vanilla

2 eggs

4:10=2:x (10×2)÷4= 5 eggs

3 cups flour

4:10=3:x (10×3)÷4= 7,5 cups flour

12 oz nuts

4:10=12:x (10×12)÷4= 30 oz nuts

What is the exact area of triangle with measures a=6 b=7 and cos C= 1/4
Julli [10]

The area of the triangle is A= (1/2)absinγ

(sinγ)Λ2+(cosγ)Λ2=1 => sinγ=√1-(cosγ)∧2= √1- (1/4)∧2=√1-(1/16)=√(15/16)=√15/4

A=(1/2)*6*7*√15/4=21*√15/4=(21/4)√15

Good luck!!!

In the right triangle shown, what is the cosine of angle C?
DiKsa [7]

Answer:

Since the legs of the right triangle measure x + 1 and x + 15, respectively, and since the hypotenuse measures x + 17, the Pythagorean Theorem can be used as follows: (x + 1)2 + (x + 15)2 = (x + 17)2. This equation becomes (x2 + 2x + 1) + (x2 + 30x + 225) = x2 + 34x + 289, which then becomes 2x2 + 32x + 226 = x2 + 34x + 289. When all the terms are moved to one side, the equation becomes x2 – 2x – 63 = 0, and when the left side of the equation is factored, it becomes (x – 9)(x + 7) = 0. At this point, it seems as if x can equal 9 or –7, but if x were –7, one of the legs would have a negative length, and this is impossible. For this reason x equals 9, and the legs of the triangle measure 10 and 24, respectively, while the hypotenuse measures 26. Since cosine is

length of adjacent leg

length of hypotenuse

, the cosine of angle C is

24

26

, or

12

13
