Tonis cat weighs 2,240 grams. How many kilograms does her cat weigh? Use 100 grams = 1 kilograms to convert the rates.
Answer: 2.24
Step-by-step explanation:
Firstly, one kilo is 1000 grams, not 100. 2240/1000=2.24
Toni's cat weighs 22.4 kilograms.
To convert grams to kilograms, we divide the weight in grams by the conversion rate of 100 grams per 1 kilogram.
For Toni's cat weighing 2,240 grams, we divide 2,240 by 100 to get the weight in kilograms.
2,240 grams / 100 grams per kilogram = 22.4 kilograms.
Therefore, Toni's cat weighs 22.4 kilograms.
The conversion rate of 100 grams to 1 kilogram allows us to easily convert weights from smaller units (grams) to larger units (kilograms). In this case, dividing the weight in grams by 100 gives us the weight in kilograms, providing a simple way to convert between the two units.

The height of a tree is 8.2 meters.
What is the tree's height in centimeters?
Answer:
820 centimeter :3
Step-by-step explanation:
8.2 meters
move the decimal back twice because of KiloHecaDecaBase (m,l,g)DeciCentiMilli
As we know 1 meter is equal to 100 centimeters so the height of the tree 8.2 meters is equal to 820 meters
What is unit conversion?The same attribute is expressed using a unit conversion but in a different unit of measurement.
For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometers, feet, or any other measurement unit instead of miles.
Measurements are frequently offered in one set of units, like feet, but are required in another set, like chains.
A conversion factor is a mathematical equation that facilitates an equal exchange of feet for chains.
Given, The height of a tree is 8.2 meters, now we know 1 meter is equal to 100cm so to convert some quantity from meters to centimeters we multiply by 100.
∴ 8.2 meters is equal to (8.2×100) = 820 centimeters.

Use DESMOS to plot both lines (attached).
If you make your own lines on the graph paper, pick two points for each line and connect them with a ruler. Both are straight lines, so we only need two points.
Pick any two values of x and solve each equation for y. I picked x = 1 and 3
EQ1: y=2x-2
EQ2: y=-x+4
