Gaining or losing weight comes down to calories burned vs. calories consumed. Burn more calories than you take in, and you’ll lose weight. Burn less than you take in, and you’ll gain weight. Simple. Let’s study some aspects of weight change.
A rule of thumb used by nutritionists is that to lose 1 lb of body fat, you need to burn 3,500 calories above what you take in. If you burn 450 more calories than you take in each day, how long will it take to lose 1 lb? What about 10 lb?

- Heart Disease In a certain country, the number of deaths due to heart disease decreased from 235 in one year to 221 in the next year. What percentage decrease in deaths due to heart disease does this represent?arrow_forwardDiet Program Nicole started a new diet that requires each meal to have 460 calories, 6 g of fiber, and 11 g of fat.

- The top three sources of oil imports for the United States in the same year were Saudi Arabia, Mexico, and Canada. The three top countries accounted for 47% of oil imports. The United States imported 1.8% more from Saudi Arabia than they did from Mexico, and 1.7% more from Saudi Arabia than they did from Canada. What percent of the United States oil imports were from these three countries?[29]arrow_forwardIn Example 5, after how many days are 250 students infected?arrow_forwardParent Volunteer Laurie was completing the treasurer’s report for her son’s Boy Scout troop at the end of the school year. She didn’t remember how many boys had paid the $24 full-year registration fee and how many had paid a $16 partial-year fee. She knew that the number of boys who paid for a full-year was ten more than the number who paid for a partial-year. If $400 was collected for all the registrations, how many boys had paid the full-year fee and how many had paid the partial-year fee?arrow_forward
- Give an example from your life using the phrase ‘at least’.arrow_forwardGrade Point Average In many universities students are given grade points for each credit unit according to the following scale: A 4 points B 3 points C 2 points D 1 point F 0 point For example, a grade of A in a 3-unit course earns 43=12 grade points and a grade of B in a 5-unit course earns 35=15 grade points. A students grade point average GPA for these two courses is the total number of grade points earned divided by the number of units; in this case the GPA is (12+15)8=3.375. a Find a formula for the GPA of a student who earns a grade of A in a units of course work, B in b units, C in c units, D in d units and F in f units. b Find the GPA of a student who has earned a grade of A in two 3-unit courses, B in one 4-unit courses and C in three 3-unit courses.arrow_forwardLaurie was completing the treasurer’s report for her son’s Boy Scout troop at the end of the school year.

- A local band sells out for their concert. They sell all 1,175 tickets for a total purse of $28,112.50. The tickets were priced at $20 for student tickets, $22.50 for children, and $29 for adult tickets.

The total value of these homes is more than 100 million dollars. Ice melting increases the sea level. Global sea level is measured relative to the sea level in the year 1870. If the sea level in 1870 is represented by 0 inches, then Cape Carmel sea level has risen from 1 6.8 inches to 8.4 inches in the years from 1992 to 2012. If the sea level rises to 24 inches, it will have devastating effects on the homes along the coast of Cape Carmel. Many of the Cape Carmel residents want to know if, and when, they should sell their property before it is washed away into the sea. You must help residents understand more about the rising sea level in Cape Carmel to help them predict when they should sell their homes. use this situation with linear model vs. an exponential models 3.
