I really need help with it’s I don’t get it

Explanation:

1. Chart shows the annual state spending in percentages, like on things to benefit both them and the public.

2. Estimate that the total is 50,000 spent. Multiply that by 0.07 for the 7% spent on highways. You get 3,500 total.

3. Add the total from the previous problem with the budget of 50,000 multiplied by 0.14 to find 14% of the entire budget. You have 3,500 for 7%, and 7000 for 14%. Add them together to get a total of 10,500.

4. A. They spend the most on other, a whopping 45%.

B. The chart shows the total percentages of the amount spent.

5. No. The graph has nothing to do with age.

i think it's c. if you look search electronic symbol on google and then click on wiki it shows you a

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
