Express this in scientific notation 13,040,000

First, to rewrite something in scientific notation, we want to move the decimal point a number of times to the right or left to end with a number between 0 and 10. In this case, we want to move the decimal point 7 times to the left to get the number 1.304. In scientific notation, this would be the same as 1.304*10^7.

I hope this helps!

8. A cable car travels 2236 m to climb a mountain that is 1000 m high. It then travels 1414 m to descend 1000 m on the other sid

frutty [35]

Answer:

3000 m

Step-by-step explanation:

Using Pythagoras theorem

$2236^2=1000^2+|AB|^2\\|AB|^2=2236^2-1000^2\\|AB|^2=3999696\\|AB|=\sqrt{3999696} \\=1999.9$

Similarly

$1414^2=1000^2+|BC|^2\\|BC|^2=1414^2-1000^2\\|BC|^2=999696\\|BC|=\sqrt{999696} \\=999.7m$

Length of the Tunnel = |AB|+|BC|

=1999.9+999.7

=2999.6

=3000 m

What is the ratio of 420m to 1 km

suter [353]

Answer:

21/50 or 21:50

Step-by-step explanation:

1km = 1000m

That means one meter is equal to 1/1000 of a km.

420 meters is 420/1000 of a km which is equal to 42/100 = 21/50 or 21:50

Is it right?

A campground has cabins that can each hold 28 campers there are 148 campers visiting the campground.how many cabins are full if

Rainbow [258]

For this case, the first thing we must do is define variables.

We have then:

x: number of cabins

y: number of campers

We now write the equation that models the problem:

$y = 28x$

We know that there are 148 campers.

Therefore, substituting y = 148 in the given equation we have:

$148 = 28x$

From here, we clear the value of x:

$x = \frac{148}{28}\\x = 5.29$

Therefore, the number of full cabins is:

$x = 5$

Answer:

The number of full cabins is:

$x = 5$
