There are 2 red, 3 blue, and 4 green marbles in a jar?<br><br> What does the ratio 4 to 9 represent?

MrMuchimi

Hello!

How many marbles are in the jar all together?

3 + 2 + 4 = 9

We also know that there are 4 green marbles in the job.

So, I would assume that the answer is;

Green Marbles : Total Marbles or Green Marbles to Total Marbles.

the speed of light is 1.86×10^5 miles per second.how many miles will light travel in 4,200,000 seconds?

stiks02 [169]

Answer: $7.812*10^{11}\ miles$

Step-by-step explanation:

Let be "x" the amount of miles light will travel in 4,200,000 seconds.

Rewrite 4,200,000 seconds in Scientific notation. Move the decimal point 6 places to the left. Then:

$4,200,000\ seconds=4.2*10^6\ seconds$

According to the exercise, light travels $1.86*10^5$ miles in 1 second.

Therefore, based on this data, you can set up the following proportion:

$\frac{1.86*10^5\ miles}{1\ second}=\frac{x}{4.2*10^6\ seconds}$

And finally, you must solve for "x" in order to find its value.

(Remember the Product of powers property: $a^m*a^n=a^{mn}$ )

Then:

$(4.2*10^6\ seconds)(\frac{1.86*10^5\ miles}{1\ second})=x\\\\x=7.812*10^{11}\ miles$

Calculate the volume of each triangular prism?

Dafna11 [192]

║Triangular Prism A║
We have to find the area of the triangle. We have 5 and 13.
5÷13=65÷2=32.5
Now multiply that by the height, 2.
32.5×2=65
The volume of triangular prism A is 65 cm³.
║Triangular Prism B║
We have to find the area of the triangle. We have 10 and 6 this time.
6×10=60
60÷2=30
Now multiply it by its height.
30×3.7
111
The volume of the triangular prism is 111 m³.
