<h3><u>Part A</u></h3>

To show the total capacity of container B is 132 cm³

volume = unit rate × time taken

volume = 6 cm³ × 22

volume = 132 cm³ ∴ Hence proved.

<h3 /><h3><u>Find radius</u></h3>

\sf volume \ of \ cone = \dfrac{1}{3} \pi r^2 h

===================

\rightarrow \sf \dfrac{1}{3} * \dfrac{22}{7}  * r^2 * 14 = 132

<em>simplify</em>

\rightarrow \sf  \dfrac{44}{3}  * r^2= 132

<em>change sides</em>

\rightarrow \sf r^2= \dfrac{132(3)}{44} = 9

<em>square root both sides</em>

\rightarrow \sf r = 3

∴ Hence the radius of cone (Shape B is 3 cm)

<h3><u>To show the time taken</u></h3>

volume = unit rate × time taken

\sf volume  \ of \ hemi -sphere = \dfrac{2}{3} \pi r^3

=========================

\sf \rightarrow  \dfrac{2}{3} \pi r^3 = 6 * time  \ taken

<em>Insert values</em>

\sf \rightarrow  \dfrac{2}{3} *\dfrac{22}{7}  \  r^3 = 6 * time  \ taken

<em>exchange sides</em>

\sf \rightarrow   time  \ taken =  \dfrac{2}{3} *\dfrac{22}{7}  \  r^3 *\dfrac{1}{6}

<em>simplify following</em>

\sf \rightarrow   time  \ taken =  \dfrac{22}{63}r^3

Answer:

x =1

Step-by-step explanation:

Assuming the figures are similar, we can use ratios to solve

x        2

---- = -----

4         8

Using cross products

8x = 2*4

8x = 8

Divide by 8

8x/8 = 8/8

x=1

a student walks 8 steps east 6 steps northeast 9 steps north west what is her displacement? include magnitude and direction
kati45 [8]

The displacement is 18.03 steps, and the direction is 47.25°

<h3>How to get the displacement?</h3>

We know that displacement is the difference between the final position and the initial position.

We assume the initial position (0, 0). Let's define the positive x-axis as the east and the positive y-axis as the north.

First, the student moves 8 steps east, so she is at:

(0 + 8, 0)

Then she moves 6 steps northeast, so the new position is:

(6*cos(45°) + 8,  6*cos(45°))

Finally, she moves 9 steps due north, so we have:

(6*cos(45°) + 8,  6*cos(45°) + 9)

Then the final position is:

(12.24, 13.24)

So the displacement is:

D = (12.24, 13.24) - (0, 0) =  (12.24, 13.24)

The magnitude of the displacement is:

|D| = \sqrt{12.24^2 + 13.24^2} = 18.03

So the magnitude is 18.03 steps.

And the direction is given by the arctangent of the quotient between the y-component and the x-component:

\theta = Arctg(13.24/12.24) = 47.25 \°

Dimas [21]

Answer:

C

Step-by-step explanation:

This is because the line was growing starting form the y-int=2.

Now the line is decreasing starting from y-int=2.

What is longer 180 seconds or 3 minutes
Neporo4naja [7]
They are both the same. There are 60 seconds in one minute, so 60*3 is 180. Since 180=180, they are equal.
