Find each unit price. Which is the better by? Explain please.
Luda [366]
1.49/3

0.5 dollars per feet.

This is a fraction equal to 1.49/3.

We want a unit rate where 1 is the denominator, so we divide the top and bottom by 3.

The answer is 0.49666667, which can be rounded to 0.5

In triangle ABC, a = 4, b = 6, and cos C = − 1/4. What is the length of side c?
shusha [124]

The length of side c would be 8.

Step-by-step explanation:

Given that,

a = 4

b = 6

cosC = -1/4

If we are given two sides and angle, the law of Cosines can be used to find the third side:

c^{2} = a^{2} + b^{2} - 2ab (cos(c))

By inserting the values in the formula, we get

c^{2} = 4^{2} + 6^{2} - 2.4.6 (-\frac{1}{4} )

c^{2} = 16 + 36 + 12

c^{2} = 64

\sqrt{c^{2} } = \sqrt{64}

c = 8.

Therefore, the length of side c would be 8.

X= ?? geometry ??? And how ????
steposvetlana [31]

Using the equations for tangent and secant lines:

Let the unknown length of the line inside the circle = y

6^2 = 3 x (y+3)

Simplify:

36 = 3y+9

Subtract 9 from both sides:

27 =3y

Divide both sides by 3:

Y = 9

Now add to get x:

X = 9 + 3 = 12

X = 12
