What is the perimeter of the triangle? if there is 2.2 cm,1 5/6cm, and 3.25 cm A. 6 1/4 cm
B. 6 17/60 cm
C. 7 1/4 cm
D. 7 17/60 cm

Answers

Answer 1
Answer: To find the perimeter of a triangle you simply add up all the sides. Because your possible answers are in fractions, I would convert the decimal values into fractions.
2.2 becomes 2 & 1/5
3.25 becomes 3 &1/4
1 & 5/6 is already a fraction, so you can leave it as it is. To combine these you need to find a common denominator (here it is 60). *It may help to convert the mixed numbers to improper fractions to add them, which is what I did*
You get:
132/60 + 110/60 + 195/60
When you add all that up you get  437/60, which is 7&17/60, so D

Whats the rate of change in y=1.5x

Answers

"Rate of change" is how much one variable changes when the other changes. In linear equations this is know as "slope" (since slope equals the change in Y relative to the change in X). Next remember that any linear equation can be written in the form: y = mx + b, where m = slope and b = y-intercept (place where line crosses the y-axis). Therefore to figure out rate of change (or slope) of a linear equation simply rewrite the equation in the y = mx + b form. In your case, the equation is already written that way. y = 1.5x (note that in this case b = 0) So in this formula m = 1.5. The rate of change is equal to 1.5. Another way this could be said is that when x increases by one unit, y will increase by 1.5 units. Plugging in any set of numbers will show this is true: If X = 1; Y = 1.5 If X = 2; Y = 3 (X increases by 1; Y increases by 1.5) If X = 3; Y = 4.5 (Again X increase by 1; Y increase by 1.5) ...

Answers

He buys 30 bottles which each costs 3 dollars. So 30 times 3 means he pays 90 dollars. Plus the 25 dollar handling fee which is 115. However the competing supplier is 4 dollars every bottle for the pint bottle. So if he bought 30 times 4 he would pay 120. That is without the handling money. So thats why he should stay with his
