Answer: Sugar is made of carbon, hydrogen and oxygen atoms. When heated over a candle, these elements react with the fire to turn into a liquid. The heat causes the sugar's atoms to combine with the oxygen in the air, forming new groups of atoms. Energy is released in this chemical reaction in the form of smoke and black soot.

To cover a rectangular region of her yard, Penny needs at least 201.5 square feet of sod. The length of the region is 15.5 feet. What are the possible widths of the region
Answer:
at least 13 feet
Explanation:
We know that the area has to be 201.5
Area is w*l and we already have the length so plug that in
15.5w≥201.5
Solve for w: 201.5/15.5
w≥13 ft
Amanda, Barney, Colin, Diana, and Erika are going to a baseball game. They have a total budget of $100.00 to spend. Each game ticket costs $17.00 and each drink costs $2.50. The inequality below relates x, the number of drinks the 5 friends could buy in all, with their ticket costs and budget. 5(17) + 2.50x ≤ 100. In your own words, tell what the 5 in the inequality represents.
Answer:
the number of game tickets that could be bought
Explanation:
Let x represent the number of drinks. Since each drink costs $2.50, therefore the total cost for drinks = 2.5x.
Each game ticket cost $17. Let y represent the number of tickets bought, therefore the total cost for tickets = 17y.
Given that the total budget = $100, hence:
total cost for drinks + total cost for tickets ≤ 100
17y + 2.50x ≤ 100 (1)
Given the equation:
5(17) + 2.50x ≤ 100 (2)
comparing equation 1 and 2, we get that y = 5. Hence 5 represents the number of tickets bought

A local newspaper claims that the number of flu cases is increasing exponentially. On Monday, there were 8 flu cases reported. On Tuesday, there were 12 flu cases and on Wednesday there were 24 cases reported. On Thursday, there were 30 flu cases. Was the newspaper's claim of exponential increase accurate?
Answer:
No, it's not an exponential increase.
Explanation:
Given the following data;
Monday = 8 flu cases.
Tuesday = 12 flu cases.
Wednesday = 24 flu cases.
Thursday = 30 flu cases.
An exponential increase has a constant ratio of proportion such as 2, 4, 16, 256, etc.
To determine if the increase is exponential, we would find the ratio of each successive reports
Tuesday : Monday = 12/8 = 1.5
Wednesday : Tuesday = 24/12 = 2
Thursday : Wednesday = 30/24 = 1.25
From the above calculations, we can deduce that the ratio of increase isn't constant. Therefore, the newspaper's claim of an exponential increase is incorrect and not accurate.
