Answer:

It takes 500 seconds

Step-by-step explanation:

Light travels at a rate of  3.0 × 10^{8} meters per second.

Distance of earth from the sun is 1.5 × 10^{11} meters.

We have to calculate the time it takes to reach the earth from sun

Since speed = \frac{Distance}{Time}

3.0 × 10^{8} = \frac{1.5\times 10^{11}}{T}

T = \frac{1.5\times 10^{11}}{3\times 10^{8}}

  = 0.5 × 10^{11} × 10^{-8}

 = 0.5 × 10^{11-8}

  = 0.5 × 10^{3}

  = 500 seconds.

It takes 500 seconds for light to travel from the sun to the earth.

I am assuming you mean 3.0 *10^8 and 1.5 * 10^11.

time = distance/speed right. So, 
t = 500 s

Margie's car can go 32 miles on a gallon of gas, and gas currently cost $4 per gallon. how many miles can Margie drive on $20 wo
Marysya12 [62]
To do this first we will divide the amount of dollars (20) by the amount of dollars 1 gallon is for (4). Then we will multiply the amount of times 4 goes into 20 by 32 and the answer will be the amount of miles she can drive worth $20. 

20 ÷ 4 = 3
3 × 32 = 96

So, Margie can drive 96 miles in $20. 

Hope I helped ya!! xD

The body of a person who weighs 50 kilograms contains around 2 × 102 grams of sodium chloride. How much sodium chloride is conta
kondaur [170]

The mass of sodium chloride required for 1. 8 × 10^3 people is 3. 6 × 10^5 grams. Option A is the correct answer.

<h3>How do you calculate the mass of sodium chloride required?</h3>

Given that weigh of the person is 50 KG. The mass of the sodium chloride in one person is given below.

1 \;\rm Person = 2\times 10^2\;\rm g

The mass of sodium chloride is calculated as given below.

1.8\times 10^3 \;\rm Person = 2\times 10^2 \times 1.8\times 10^3

1.8\times 10^3 \;\rm Person = 3.6\times 10^5\;\rm g

Hence we can conclude that the mass of sodium chloride required for 1. 8 × 10^3 people is 3. 6 × 10^5 grams. Option A is the correct answer.

To know more about the mass, follow the link given below.

How much water can this container hold
harina [27]

Answer:

972π cm³

Step-by-step explanation:

Okay so this container is a sphere, so you're going to want to use the volume of a sphere equation V = (4/3) * π * r³. In this case, you've got the diameter (d = 18), so divide by 2 to get r = 9.

So now you have all the variables you need to solve. Substituting those values into the volume equation, you get:

V = (4/3) * π * 9³ = 972π cm³.
