The amount paid for different weights of oranges at a farmer’s market are shown below. oranges (lb) price ($) 2 3 3 4.50 5 7.50 ? 12 (a) is the relationship between the price and the weight of the oranges proportional? (this is asking if there is a ratio relationship.) use the first three rows of data to answer this question. show your work and explain. (b) how many pounds of oranges cost $12? show your work.

To know if there is a relation between the price and weights of oranges. we must calculate the unit price for each given set of data.
for the first data 2 lb, $ 3
so the unit price is $3 / 2 lb = $ 1.5 / lb

for the second data 3 lb, $ 4.50
the unit price = $ 4.50 / 3 lb = $ 1.5 / lb

third data, 5 lb , $7.50
the unit price = $ 7.50 / 5 lb = $ 1.5 / lb. so they have a linear relationship.

lb oranges = $ 12 ( 1 lb / $ 1.50) = 8 lb of oranges cost $ 12

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
