Marie wants to draw a painting with an area of 40 square inches. If she draws her painting on 1 inch grid paper.
Sentence 4 is more suitable than others
Two things you need to know: 1. csc x = 1 / sin x 2. lim as x->0 (sin x / x) = 1 See if you can simplify your question using these equations, and arrive at an answer (which I think is not 0).
Use these to figure it out: Area of a square = (length of side) * (length of side) Perimeter of a square = 4 * length of side Difference, I hope you know, means you subtract one value from the other. :)
The average of a list of numbers = sum of numbers divided by (how many numbers there are) So what you're looking for is: sum of angles of a triangle divided by (how many angles there are in a triangle) (I'm hoping you can fill in the values yourself)
Actually, since you posted this as arithmetic, let me try to give an explanation without algebra. Let's say you just had 1 of each coin. Then, you would have a total of 0.25 + 0.1 + 0.05 + 0.01 = 1.23. Now if you had any other number of each type of coin,
Let's say you have x number of each type of coin. Then, the total amount you have, in dollars, is 0.25x + 0.1x + 0.05x + 0.01x = 1.23x. Since x is a whole number, the total amount you have has to be a multiple of 1.23, which leaves one of the options you
Let me give you a hint. Think of all the different ways in which you can add three whole numbers (the lengths of the three sides) to get 6 (the perimeter). You'll find that there are 3 ways to do that, of which 2 will be invalid because of a certain
Haven't done real science in a while (studied computer science in college), but I'll give it a shot. I hope you actually want to learn the concepts a little bit (if you just wanted the answer, you could probably have googled the questions), so I'll explain
