3.0 x 10^8 km/s is how far light travels.
3.0 x 10^8 km/s x 60s is how far light travels in a minute
3.0 x 10^8 x 60 x 5 is how far light travels in 5 minutes, and you should get D as your answer.

Answer:

D) $9*10^{10}$ km.

Step-by-step explanation:

Given : Light travels at $3* 10^{8}$ km/s.

To find : How far does light travel in 5 minutes.

Solution : We have given

Light travels in 1 second = $3* 10^{8}$ km.

1 minute = 60 second.

5 minute = 60* 5 = 300 second .

Light travels in 5 minute = $300 * 3* 10^{8}$ km.

Light travels in 5 minute = $3*10^{2}* 3*10^{8}$ km.

= $9*10^{10}$ km.

Therefore, D) $9*10^{10}$ km.

PLEASE ANSWER ASAP!! e)What is the measure of ∠I? Explain

Zina [86]

Answer:

$60^{\circ}$

Step-by-step explanation:

From the given figure it is clear that the stop board is a regular hexagon and ∠I is an exterior angle of the regular hexagon.

Exterior angle of a regular polygon with n sides $=\dfrac{360^{\circ}}{n}$

In a regular hexagon number of sides: n =6

Exterior angle of a regular hexagon $=\dfrac{360^{\circ}}{6}=60^{\circ}$

Since ∠I is an exterior angle of the regular hexagon, therefore, $\angle I=60^{\circ}$ .

The function C(x) = 29x + 54.5 represents the cost (in dollars) of cable for x months, including $54.50 installation fee. How ma

Ratling [72]

Hey there!!

Given equation :

... c(x) = 29x + 54.5

<em>In this equation $54.50 is installation fee and this would remain as a constant. ( This value wouldn't change ). </em>

<em>'x' is represented as the number of months. </em>

The total cost or c(x) is given as $344.50

Getting this into equations :

... 344.50 = 29x + 54.5

Subtracting 54.5 on both sides :

... 29x = 290

Dividing by 29 on both sides :

... x = 10

<u><em>Hence, the number of months is 10. </em></u>

Hope my answer helps!!

What is the measure in radians for the central angle of a circle whose radius is 8 cm and intercepted arc length is 7.2 cm? Ente

natulia [17]

The measure in radians for the central angle of the circle is; 0.9 radians.

<h3>What is the angle measure in radians of the central angle?</h3>

Since, the length of the arc is given as 7.2cm and it's radius is 8cm.

It follows that the angle measure of the central angle can be evaluated as follows;

7.2 = (A/6.28) × 2× 3.14 × 8

7.2 = 8A

A = 7.2/8

A = 0.9 radians.
