Answer:
13)
Line A - slope/constant of proportionality = 5/2
Line B - slope/constant of proportionality = 2/3
14)
unit rate = 3/2 or 1.5
The unit rate, 3/2, is greater than line B's unit rate but is less than line A's unit rate.
Step-by-step explanation:
To find the constant of proportionality for question 13 you use the graph. k = y/x so you find the point at (4, 10) and you go up 10 (y) and over 4 (x). So now you have 10/4 and then you simplify to 5/2. Use the same method for line B to find the slope. Now for question 14 you subtract 10 - 5 to get 5 which is your x and 15- 7.5 to get 7.5 which is the y. So this is now 7.5/5 (y/x) or 3/2. 3/2 is less than 5/2 and greater than 2/3.
Thank you so much!!! Hope this helps!!!
Answer:
Imagine if your friend is 3ft, and he is scaled down into the drawing. If he's scaled down into the drawing, he would be 1 inch in the drawing. If your cat were 1.5ft, it would be half of your friend, so in the drawing it would be 0.5 inch. Now the table is 9ft, how many 3ft is in 9ft? That's 3 times of 3ft, so 1 inch would be multiplied 3 times, = 3 inches. Or there's a shortcut way in the pic.
Yes it is.
2/3
2*3 / 3*3
6/9
7/9 > 6/9 = 2/3
7/9 > 2/3
Answer: Yes, 7/9 > 2/3
Pythagorean theorem
c2 = a2 + b2
58^2 = 42^2 + b2
3364 = 1764 + b2
1600 = b2
b = 40
