Match each table showing a proportional relationship between x and y with its constant of proportionality.

Step-by-step explanation:

Just divide y by x and what ever you get is the answer

Hope this helps!

The first one (1-4, 2-8, 3-12) belongs to 4

The second one (2-4, 4-8, 6-12) belongs to 2

The third one (4-6, 8-12, 12-18) belongs to 3/2

The last one (1-6, 2-12, 3-18) belongs to 6

Step-by-step explanation:

I divided the y numbers from the x

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
