Jeremy buys a value pack of cheese crackers that contains 42 and 1 over 2 ounces of crackers. He divides this into servings of 1 and 1 over 4 ounces each. What is the total number of servings Jeremy can make from the value pack?

Answer 1

Since 1 and 1 over 4 ounce is equal to 5/4 ounce, dividing 42 and 1 over 2 ounces by 5/4 ounces gives [(42 and 1 over 2)+(1 over 2)] / 5/4 = [(85/2)+(1/2)] / 5/4
= [(86/2)] / 5/4 = 43 / 5/4 = 43/1 * 4/5 = 172/5 = <<43/1*4/5=34.4>>34.4 servings. Answer: \boxed{34.4}.

Answer 2

A hot air balloon leaves the ground and rises to an elevation of 1,100 feet. During the next 30 minutes, it descends 500 feet, rises 950 feet, descends 375 feet, and finally passes over a school. What is the elevation of the balloon when it passes over the school?

Answer 3

The balloon starts at an elevation of 0 feet and rises to 1,100 feet. It then descends 500 feet, rises 950 feet, and descends 375 feet before passing over the school.

The total change in elevation can be calculated as follows:
+1,100 - 500 + 950 - 375 = 2,175 feet

Therefore, the elevation of the balloon when it passes over the school is 2,175 feet. Answer: \boxed{2175}.
