Answer:
Option A- One
Step-by-step explanation:
Given that : The sides of the triangle measuring 6cm, 2cm and 7cm.
We are using : Triangle inequality
The sum of the length of the two sides should be greater than the length of the third side.
So, when we apply this theorem in 6cm,2cm and 7cm
6+2=8>7 , 7+2=9>6 , 7+6=13>2
It satisfy all three possible sets.
Therefore, the given values follows the triangle inequality.
Hence one triangle can be formed.
Therefore, option A is correct.
Answer:
2nd graph (image)
Step-by-step explanation:
The function to graph is:
It follows the general pattern of the function: , which is general shape and in 1st and 3rd quadrants. So, we can eliminate 3rd and 4th choices (because of quadrants).
The answer is either 1st, or 2nd graph.
Now, we simply can check a point in both.
lets take x = 4, so the function would be:
f(4) = 4/4 = 1
Hence, point is:
(4,1)
The first graph doesn't go through this point. The second graph does.
hence, we can successfully choose the 2nd graph as our answer.
Let x represent the number of minutes and y the cost. Then
y - 0.85 = (1.10 - 0.85)/(10 - 5) (x - 5)
y - 0.85 = 0.25/5 (x - 5) = 1/20 (x - 5) = 1/20 x - 1/4
y = 0.05x - 0.25 + 0.85 = 0.05x + 0.6
y = 0.05x + 0.6
The cost of 25 minutes = 0.05(25) + 0.6 = 1.25 + 0.6 = $1.85
Answer:
Step-by-step explanation:
The equation has a slope of 4
The graph has a slope of 1
The equation has a greater rate of growth.
3 ÷ 2 = 1.5
So each student had a pack and a half.
Hope this helps. :)
