Look at the triangle below which of the following represents two of the angle measures of the triangle

Gelneren [198K]

Answer:

C. 60° and 80°

Step-by-step explanation:

Sum of triangle = 180°

Therefore,

8x + 4 + 6x - 2 + 10x + 10 = 180

Add like terms

8x + 6x + 10x + 4 - 2 + 10 = 180

24x + 12 = 180

24x = 180 - 12

24x = 168

x = 168/24

x = 7

Find each measure of the angles by substitute x = 7 into each expression

8x + 4 = 8(7) + 4 = 60°

6x - 2 = 6(7) - 2 = 40°

10x + 10 = 10(7) + 10 = 80°

The answer is 60° and 80°

14. Let R^2 have inner product defined by ((x1,x2), (y,, y2)) 4x1y1 +9x2y2 A. Determine the norm of (-1,2) in this space B. Dete

Vitek1552 [10]

The norm of a vector $\vec x$ is equal to the square root of the inner product of $\vec x$ with itself.

a. $\|(-1,2)\|=\sqrt{\langle(-1,2),(-1,2)\rangle}=\sqrt{4(-1)^2+9(2)^2}=\sqrt{40}=2\sqrt{10}$

b. $\|(3,2)\|=\sqrt{\langle(3,2),(3,2)\rangle}=\sqrt{4(3)^2+9(2)^2}=\sqrt{72}=6\sqrt2$

A ratio shows us the number of times a number contains another number. The amount barely needed for 300 ml of milk is 45 grams.

<h3>What is a Ratio?</h3>

A ratio shows us the number of times a number contains another number.

The need for barley in 200 ml of milk is 30 grams, therefore, the need for barley in 1 ml of milk can be written as,

Need of barely in 1 ml of milk = 30/200

Now, the amount of barely that will be needed for 300 ml of milk will be,

The amount of barely in 300 ml of milk = (30/200)×300 = 45 grams.

Hence, the amount barely needed for 300 ml of milk is 45 grams.
