The answer is B because e is 2.17
Unit rate means one. So the best way to solve this is using a proportion over one. If there are 258 pencils in 3 purses 258/3 then how many are in one purses x/1. Cross multiply next.
258/3 * x/1. You get 3x and 258. To get the x alone, divide both sides by three. Your answer is 86 pencils in one purse.
The answer would have to be 52/87. Since it says "given", as in a geometric sense (proof), you know that the overall would have to be 87. It also adds that the students would be in the 10th grade, thus bringing us to the conclusion that 52/87 is correct. Then, simply use a calculator and put in 52/87. You're final answer, rounded to the nearest hundredth, should be 0.60.
Answer:
d. 40
Step-by-step explanation:
The number of faces, edges and vertices is related by the following formula:
In which V is the number of vertices, E is the number of edges and F is the number of faces.
In this question:
We want to find E. So
The correct answer is given by option D.
