George wants to buy a new bike, which cost $280. So far, he has earned $56. What percent of the total price has he already earned?

20%

Step-by-step explanation:

Step one: divide how much you have by how much you need. The result is 0.2.

Here you have multiple way to remember how to do, pick the one you like most.

a. turn it in a fraction: 0.2 = 2/10 = 20/100, or 20%.

b. multiply by 100: 0.2x100 = 20, so 20%

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

the battle of gettysburg is considered the "high water mark" of the confederacy because it marked the greatest advance of the confederate forces against the union.
