Answer:

56.25°

Step-by-step explanation:

The definition of the cosine function tells you that

cos(B) = BC/BA

B = arccos(BC/BA) = arccos(5/9)

B ≈ 56.25°

What are all the simplified form of the equation 3(4x - 2) = 9 + 2x + 5

Alexeev081 [22]

Step-by-step explanation:

<u>Step 1: Distribute</u>

$3(4x - 2) = 9 + 2x + 5$

$(3 * 4x) + (3 * -2) = 14 + 2x$

$12x - 6 = 14 + 2x$

<u>Step 2: Add 6 to both sides</u>

$12x - 6 + 6 = 14 + 6 + 2x$

$12x = 20 + 2x$

<u>Step 3: Subtract 2x from both sides</u>

$12x - 2x = 20 + 2x - 2x$

$10x = 20$

<u>Step 4: Divide both sides by 10</u>

$10x / 10 = 20 / 10$

$x = 2$

Answer: $x = 2$

The variable x varies directly as the cube of y, and y varies directly as the square root of z. If x equals 1 when z equals 4, w

Aloiza [94]

Answer:

<h2> $z=36$ </h2>

Step-by-step explanation:

According to the question,

$x$ ∝ $y^3$ .......(1)

$y$ ∝ $\sqrt{z}$ .......(2)

From equation 1,2 let constant of proportionality be $k1,k2$ respectively.

⇒ $x=k1(y^3)$ .......(3)

⇒ $y=k2(\sqrt{z} )$ .......(4)

From the above equations putting 4 into 3,

$x=k1((k2\sqrt{z})^3) =k1.k2^3.(\sqrt{z})^3$

Let the new constant to the above equation be $k3$ ,

$x=k3(\sqrt{z})^3$

Given,if x=1, when z=4

$1=k3(\sqrt{4} )^3=k3(8)$

⇒ $k3=\frac{1}{8}$

Now if x=27, then z=?

$27=\frac{1}{8} (\sqrt{z} )^3$

⇒ $(\sqrt{z} )^3=27(8)$

⇒ $\sqrt{z}=3(2)=6$

$z=36$

Answer:

7.6

Step-by-step explanation:

mean = [weights] / amount of weights

m = 10 + 7 + 6 + 10 + 13 + 10 / 6

m = 46 / 6

m = 7.66666666 (recurring)

m = 7.6
