Kateri draws a square. She wants to draw one line to draw one line to divide the square into 2 triangles. Is it possible for her
Vika [28.1K]
No. Since you can only draw from the corners to get triangles, you will end up with two right triangles because of the corners. If it is a right triangle, it can obviously not be obtuse.

The math club sells candy bars and drinks during football games.
Vinvika [58]

Answer:

The price of candy bar is 75 cents

Step-by-step explanation:

Let c be the price of candy bar and d be the price of drinks

Then according to given statements

60c+110d = 265\ \ \ \ Eqn\ 1\\120c+90d = 270\ \ \ \ Eqn\ 2

Multiplying equation 1 by 2

120c+220d = 530\ \ \ \ Eqn\ 3

Subtracting equation 2 from equation 3

120c+220d - (120c+90d) = 530 - 270\\120c+220d-120-90d = 260\\130d=260

Dividing both sides by 130

\frac{130d}{130} = \frac{260}{130}\\d = 2

Putting d=2 in equation 1

60c+110(2) = 265\\60c + 220 = 265\\60c+220-220 = 265-220\\60c=45\\c = \frac{45}{60}\\c = 0.75

Price of candy bar is $0.75 or 75 cents

Hence,

The price of candy bar is 75 cents
