Answer:
2/6 (33.33%)
Step-by-step explanation:
Answer:
c
Step-by-step explanation:
Since they are similar, you need to find the ratio of similarity (I made up the term, there is probably a correct one that I can’t remember).
If you divide 16/40, you’ll find that that ratio is 2.5. So then you just multiply 16 x 2.5. You’ll get 18.
18 is the length of the top of the trapezoid.
You set 18=2x+4 and solve it algebraically. Subtract 4 from both sides.
14=2x
Divide by 2 and x=7
(You can also check that the ratio is right by 16/18 is the same decimal value as 40/45. You’ll get .88888...)
Divide total # kg by the # of parts it is divided in to.
=3 kg ÷ 5 parts
=3/5 kg
Hope this helps! :)
Slope = 18/6 = 3
Y-intercept = -6
Equation: y = 3x -6
