Answer:

A. 60°

Step-by-step explanation:

There's a very straight-forward explanation for this, thank god! XD

For this type of problem, there's a rule to follow for the outside angle. X and 120 should equal 180, so all you need to do is fill that gap.

180-120 = 60

60 is your answer because it completes the whole angle.

It is known that the point P(-9,18) belongs to the graph of the function y=k/x. Find k.

riadik2000 [5.3K]

Answer:

$k = (-162)$ .

Step-by-step explanation:

A point of the form $(x_{0},\, y_{0})$ belongs to the graph of this function, $y = k / x$ , if and only if the equation of this function holds after substituting in $x = x_{0}$ and $y = y_{0}$ .

The question states that the point $(-9,\, 18)$ belongs to the graph of this function. Thus, the equation of this function, $y = k / x$ , should hold after substituting in $x = (-9)$ and $y = 18$ :

$y = k / x$ .

$18 = k / (-9)$ .

Solve this equation for the constant $k$ :

$\begin{aligned}k &= 18 \times (-9) \\ &= (-162)\end{aligned}$ .

Thus, $k = (-162)$ .

kemdrick is an ecologist he spends 8 hours on friday how many hours he spending on saturday to average 11 hours per day

Sidana [21]

Answer:

$\boxed{13}$

Step-by-step explanation:

Let x = hours worked on Saturday

Then x + 8 = total hours on Friday and Saturday

$\text{Average} = \dfrac{ \text{total hours}} {\text{number of days}}\\\\11 = \dfrac{x + 8}{2}$

22 = x + 8

x = 13

Kendrick is working $\boxed{13}$ hours on Saturday.

What is the volume of the cone?

Radda [10]

Data:
r (radius) = 6 cm
h (height) = 12 cm
V (volume)= ?

Formula:
$V = \frac{ \pi * r^2 * h}{3}$

Solving:
$V = \frac{ \pi * r^2 * h}{3}$
$V = \frac{ \pi * 6^2 * 12}{3}$
$V = \frac{ \pi *36*12}{3}$
$V = \frac{432 \pi }{3}$
$\boxed{\boxed{V = 144 \pi cm^3}}\end{array}}\qquad\quad\checkmark$

Answer:
<span>D 144 pi cm^3</span>
