How far above sea level is the ranger station?

Schach [20]

Since he descended 12 meters, we subtract this from the overall height of Mount Ka'ala, so then we are only calculating how high ABOVE the sea level it is.

1232 - 12 = 1220

The height of Mount Ka'ala is therefore 1,220 meters.
To calculate how much a fifth of Mount Ka'ala is (since the ranger station is 2/5's up), we would divide this number by 5

1220 ÷ 5 = 244

Since ONE fifth of the height is 244 meters, TWO fifths would be double that amount.

244 x 2 = 488

488 meters.
The ranger station is 488m above sea level.

FIND THE VOLUME OF A CONE 0F DIAMETER 14M AND HEIGHT 21CM. (TAKE = 3 )

Ksenya-84 [330]

Answer:

343π

Step-by-step explanation:

To find the volume of a cone, we have to use this formula

$\frac{1}{3}$ × π × r² × h

Where 'r' is the radius and 'h' is the height

Let's start putting in the value's

We have diameter but in the formula we need the radius so we half the diameter to get the radius so 14 ÷ 2 = 7

$\frac{1}{3}$ × π × r² × h

$\frac{1}{3}$ × π × 7² × 21

→ Simplify the expression

$\frac{1}{3}$ × π × 49 × 21

→ Simplify it further

343π

The math teacher gives each student a map of the amusement park that use a coordinate plane the meeting locates is at(0,0) on th

GrogVix [38]

Given:

Starting point = (0,0)

First ride = (0,4)

Second ride = (3,0)

In map, each unit = 100 ft

To find:

The actual distance between first and second ride.

Solution:

Distance formula: Distance between two points is

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Using the distance formula, we get the distance between first ride and second ride in the map is

$d=\sqrt{(3-0)^2+(0-4)^2}$

$d=\sqrt{9+16}$

$d=\sqrt{25}$

$d=5$

So, the distance between first ride and second ride in the map is 5 units.

We have,

1 units = 100 ft

5 units = 500 ft

The actual distance between first and second ride is 500 ft.

Therefore, the correct option is C.
