We have learned that the sum of the angles of a triangle is equal to 180 degrees. Is that just a random number? Why do you think

the sum is 180? Can you prove it?

For example if you take a right triangle, one angle is already 90 degrees. The other 2 angles measure would be determined by knowing that a triangle’s inside angles add up to 180. So the other 2 angles are 45 degrees each. Also it is not just a random number. It is based on a protractor. Hope this helps!

When the graph is constant, you have to look for when it draws a straight line. 
Look at the x axis, since it asks for the x value. 

Your answer is correct! When x = 0, to x = 3, the function is constant.

Can someone explain to me taxes?
jeka94

taxes
According to the oxford dictionary, the word taxes defines as a compulsory contribution to state revenue, levied by the government on workers' income and business profits, or added to the cost of some goods, services, and transactions.

explanation
Money is taken from your yearly earnings to pay for services such as the Police, Emergancy Services, Military, Schools, Postal Service ect. It is also used to pay workers who work in a federal agency such as Postal Workers and the FBI. Citizens of the United States are taxed on items that are non-edible, such as a TV, and phones in stores. Tax percentages differ in every state.

Taxes are destributed to states so the states could build roads, schools, police stations and a lot more stuff.

The country can run Social Programs such as Social Security from taxes.

When it hatches from its egg, the shell of certain crab is 1cm across. When fully grown the shell is approximately 10cm across.
inn [45]
Well every time it gets rid of a shell it grows 1 1/3 times larger. So so to see how much it grows after the first time you say
1 cm * 1 1/3 = 1 1/3 cm

to get the next one you do the same
1 1/3 cm * 1 1/3 cm = 16/9

It will keep going multiplying by 1 1/3. So so we can say in an equation that the
(initial size) * 1 1/3 *(number of shells) = length

Or 1cm * 1 1/3 * n = L

We we know the final length is 10cm

So 1 1/3 * n = 10cm

n = 7.5shells

so approximately 7 or 8 shells
