Shannon needs 9 feet of ribbon for an art project. how many inches of ribbon should she buy if she is making 4 projects

432 inches

Explanation:

Given : length of ribbon needed by Shannon for an art project = 9 feet

As we know : 1 feet = 12 inches

9 feet =

Thus if for 1 project , length of ribbon required is = 108 inches

For 4 projects , length of ribbon required is =

Thus 432 inches of ribbon should she buy if she is making 4 projects.

i wish i could but this one is weird give me abc and i can solve it.

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
