As AB and ED are parallel, they have the same slope. This means that since lines that are colllinear with parallel segments are parallel, lines l and m are parallel.

Alan bought a suit on sale for $208. This price was 35% less than the original price.
algol [13]

Answer:

280.8

Will measures the distance around a tree using a tape measure as 48 inches. Use this measure to find the diameter of a cross sec
marin [14]

Answer: Assume the cross section is taken at the same height where the circumference was measured. Then


48/3 = 16 inches, close enough, actually. Trees aren't cylinders.


48 × 7 / 22 inches = 15.2727272

48/3.1415926 = 15.2788747

48/pi = 15.2788745368219522338128412837... ☺️



Step-by-step explanation:

circumference / diameter = pi = 3.1415926......

So diameter = circumference / pi.

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
