The area of triangle LMN is 18 ft2 and the area of triangle FGH is 24 ft2. If , what is the ratio of LM to FG?

In two similar triangles, the ratio of their areas is the square of the ratio of their sides. Let's assume LMN and FGH are similar triangles. The ratio of the areas of LMN to FGH is 18 to 24, or 3 to 4 or 0.75. We would then take the square root of 0.75 to get the ratio of the sides. I get 0.866. The reason it is the square is the area of a triangle is base times height divided by 2, and the base and height and sides of similar triangles are proportional.

Good luck.

What is a proportion ?

A proportion is an equality between ratios. Let a/b and c/d be two ratios. If the two ratios are equal you can write a/b=c/d. This equality constitutes a proportion.

I dont know what a ratio is

A ratio is a division of two quantities that may or may not be of the same nature.

Same nature
You can for example have the ratio of the perimeters of two similar triangles. ratio=perimeter1/perimeter2

Different nature
:
If an automobilist travels at a constant rate (notice the root RATE, RATIO), the rate of travel is expressed as the ratio of the distance travelled (d) to the time taken to travel the distance. That ratio is called the speed v
v=d/t
Since the ratio involves two quantities of different nature, the speed has a unit derived from the unit of distance and the unit of time; Example v=65 km/h

Other examples:
There is a ratio of 1.45 US \$ to 1 Euro. This is usually referred to as the exchange RATE.
The odds of something happening is 7 to 2.

What is really meant when a ratio is involved depends on the context. But what you should remember is that a ratio involves the division of two quantities.
Proportions: The equality of two ratios is called a proprtion.

How to zoom in on info

When TVs first appeared, they had an picture ratio of 4:3, which matched that of most movie screens at the time. Terrified of losing their business, movie studios struck back with "widescreen" films using 1.85:1 or 2.35:1 ratios. When widescreen TVs started appearing, they emulated those same ratios, but many TV shows (and some movies) were still in 4:3---and we were eventually left with a bit of a mess. Canny manufacturers, including LG, have solved the problem by allowing you to adjust the picture ratio on the TV to fit the program you're watching. If it's not set properly, however, your image will look distorted or cut off. A quick bit of troubleshooting can fix the problem easily.

1. Press the "Menu" button on the remote and scroll down to the "Option" title (it should be second from the bottom ). Then select "Aspect Ratio." You should see a list of ratio options. You simply need to pick the one which fits the show you're watching.
2. Choose the 4:3 ratio for older movies and TV programs. You should see a pair of bars on the left and right side of the screen. (That's okay: the bars keep the program in the same proportion in which it was filmed.)
3. Select the 16:9 ratio for widescreen movies and for more recent shows to match their longer width. For some movies, you may see black bars and the top and bottom of the screen. Again, that allows the movie to be shown in the manner it was filmed.
4. Pick "Set By Program" to automatically switch the LG TV between 4:3 and 16:9 to match whatever show is on at the time.
5. Select "Horizon" to horizontally expand the image onscreen. It will fill the whole screen---eliminating the black bars to the left and the right---but it may look distorted.
6. Use the "Zoom 1" option to zoom the image forward. That will eliminate the black bars at the top or the bottom of the screen, though you will cut off the edges of the image.
7. Pick the "Zoom 2" button to select a midway point between "Horizon" and "Zoom 1." The picture is stretched, but not as much as with "Horizon," and fills the screen, but doesn't cut off as much as "Zoom 1."
8. Use the "Cinema Zoom" button to enlarge the picture to fit the screen. This option allows you to adjust the proportion to your liking, rather than use the set proportions of the other aspect options.
9. Exit the menu when you are done and watch your programming normally.

Why did my picture become big so I can not see the sideline information

Press the RATIO button repeatedly to select the desired picture format. You can also adjust Aspect Ratio in the OPTION menu.
1. Set By Program. Selects the proper picture proportion to match the source’s image. (4:3 → 4:3, 16:9 → 16:9)
2. 4:3. Choose 4:3 when you want to view a picture with an original 4:3 aspect ratio, with gray bars appearing at both the left and right sides.
3. 16:9. Choose 16:9 when you want to adjust the picture horizontally, in a linear proportion to fill the entire screen.
4. Horizon. Choose Horizon when you want to adjust the picture in a non-linear proportion, that is, more enlarged at both sides, to create a panorama view.
5. Zoom 1. Choose Zoom 1 when you want to view the picture without any alteration. However, the top and bottom portions of the picture will be cropped.
6. Zoom 2. Choose Zoom 2 when you want the picture to be altered, both horizontally extended and vertically cropped. The picture taking a halfway trade off between alteration and screen coverage.
7. Cinema Zoom. Choose Cinema Zoom when you want to enlarge the picture in correct proportion. Note: When enlarging or reducing the picture, the image may become distorted. You can adjust the enlarge proportion of Cinema Zoom using D / E button. The adjustment range is 1~16.

How many atoms are present?

(0.540 g)(6.02 1023 atoms) 27.0 g 1.20 1022 atoms

Because density equals mass per unit volume, the mass of the cube is m V (2.70 g/cm3)(0.200 cm3) 0.540 g write this relationship twice, once for the actual sample of aluminum in the problem and once for a 27.0-g sample, and then we divide the first equation by the second: m sample m 27.0 g kN sample kN27.0 g

m sample m 27.0 g

Nsample N27.0 g

To solve this problem, we will set up a ratio based on the fact that the mass of a sample of material is proportional to the number of atoms contained in the sample. This technique of solving by ratios is very powerful and should be studied and understood so that it can be applied in future problem solving. Let us express our proportionality as m kN, where m is the mass of the sample, N is the number of atoms in the sample, and k is an unknown proportionality constant. We

Notice that the unknown proportionality constant k cancels, so we do not need to know its value. We now substitute the values: 0.540 g 27.0 g Nsample 6.02 N sample 1023 atoms

Icons and screen not sized properly-too big and out of proportion

Click Properties
Click on the Settings Tab
It will say resolution with a sliding bar, you can move that around untill you find the right aspect ratio. Try 1024x768..

Hope that helps let me know :)

I don't know the proportions of mixer to petrol for a leaf blower

you are not going to hurt the unit if you run a 20:1 ratio on the unit until your friend gets ahold of you and then lets you know the proper ratio. when I use mine I do a 20:1 ratio and sometimes I just guess and have had the same blower for over 6 years now. McCulloch is apart of husqvarna and ushally theirs are a 20:1 ratio as well on the smaller units. bigger the unit ushally the bigger the ratio.

Math

ratio: a comparative value. "so many pounds to ounces"
i.e. 3 to 1
proportion: a part of the original. a percentage of the whole.
i.e.: a proportional band of a thermostat. that "dead zone" between the set point and the desired point is 10 degrees.
