Answer 16

To find the number of servings, we need to divide 42 1/2 by 1 1/4. We can rewrite 42 1/2 as 85/2 and 1 1/4 as 5/4. Dividing these fractions, we get (85/2)/(5/4). To divide fractions, we multiply the first fraction by the reciprocal of the second fraction. So, we have (85/2)*(4/5) = (85*4)/(2*5) = (340)/(10) = <<340/10=34>>34. Answer: \boxed{34}.

Answer 17

The balloon rises to an initial elevation of 1,100 feet, then descends 500 feet, rises 950 feet, and descends 375 feet.

So, 1,100 - 500 + 950 - 375 = 2,900 feet.

Therefore, the elevation of the balloon when it passes over the school is 2,900 feet. Answer: \boxed{2900}.

Answer 18

The elevation of the balloon when it passes over the school is 1,550 feet. Answer: \boxed{1550}.

Answer 19

Aaron earns $7.25 per hour and works 3 1/2 hours every Saturday. To find his weekly pay, we multiply his hourly rate by the number of hours he works:

$7.25/hour * 3.5 hours/week = $25.37/week

Next, we need to find his monthly pay by multiplying his weekly pay by the number of weeks in a month (4):

$25.37/week * 4 weeks/month = $101.48/month

If Aaron receives a $1.00 raise, his new hourly rate will be $7.25 + $1.00 = $8.25.

Using his new hourly rate, we can calculate his new monthly pay:

$8.25/hour * 3.5 hours/week * 4 weeks/month = $115.50/month

Therefore, Aaron will be paid $115.50 in his next paycheck. Answer: \boxed{115.50}.

Answer 20

To evaluate the expression 2/3(-6+4), we need to follow the order of operations, which is parentheses, multiplication and division from left to right.

First, we simplify inside the parentheses: (-6 + 4) = -2.

Next, we divide -2 by 3: -2/3.

Finally, we multiply -2/3 by 2: (-2/3) * 2 = -4/3.

Therefore, the value of the expression 2/3(-6+4) is -4/3. Answer: \boxed{-\frac{4}{3}}.

Answer 21

Let's calculate the total cost of the skateboard and helmet first.

The cost of the skateboard is $45.50 and the cost of the helmet is $18.25.

So, the total cost is $45.50 + $18.25 = $63.75.

Jason earned 1/3 of the total cost by mowing lawns. To find the amount he earned babysitting, we need to subtract this from the total cost.

Jason earned 1 - 1/3 = 2/3 of the total cost by babysitting.

To find the amount Jason earned babysitting, we multiply 2/3 by the total cost:

($63.75)(2/3) = $42.50.

Therefore, Jason earned $42.50 babysitting. Answer: \boxed{42.50}.

Answer 22

To determine which expression results in a negative number, let's simplify each expression:

1/2(-2x2/5) = -2/5. Since this expression is negative, it fits the criteria.

1/3(-18) divided -3 = (-6) / (-3) = 2. This expression is positive.

- 1/4(-7-6) = -1/4(-13) = 13/4. This expression is positive.

-1/2 divided - 2/3 = (1/2) / (-2/3) = -3/4. Since this expression is negative, it fits the criteria.

Therefore, the expressions 1/2(-2x2/5) and -1/2 divided - 2/3 result in negative numbers.

Answer 23

If the recipe calls for one-third of a tablespoon of cinnamon for one large cake, and Jerri is making four small cakes, she will need to divide the amount of cinnamon by 4.

To find one-fourth of one-third of a tablespoon, we multiply one-third by one-fourth:

(1/3) * (1/4) = 1/12.

Therefore, Jerri should use 1/12 tablespoon of cinnamon for each of the four small cakes. Answer: \boxed{\frac{1}{12}\text{ tablespoon}}.

Answer 24

To find out how much Molly's family plans to spend on meals, we'll need to follow the steps given in the problem.

The family plans to spend 3/5 of $3,000 on gasoline and motel rooms. To find this amount, we'll multiply $3,000 by 3/5:

($3,000) * (3/5) = $1,800.

Now, we need to find 1/2 of the remainder, which is the amount left after spending on gasoline and motel rooms. The remainder is $3,000 - $1,800 = $1,200. To find 1/2 of $1,200, we'll multiply $1,200 by 1/2:

($1,200) * (1/2) = $600.

Therefore, Molly's family plans to spend $600 on meals. Answer: \boxed{600}.

Answer 25

Since m is located to the left of n on the number line, we can conclude that m is less than n.

From this, we can deduce that n - m will be positive because subtracting a smaller number from a larger number will result in a positive value.

Therefore, the statement "The value of n - m is positive" is true.

Answer 26

To evaluate this expression, we'll follow the order of operations: multiplication, addition, and division.

First, let's calculate 1/2 multiplied by 4/3:
(1/2) * (4/3) = 4/6 = 2/3

Next, let's add 2/3 to 5/6:
(2/3) + (5/6) = (4/6) + (5/6) = 9/6 = 3/2

Finally, let's divide 3/2 by 7/8:
(3/2) / (7/8) = (3/2) * (8/7) = (3*8) / (2*7) = 24/14 = 12/7

Therefore, the result of this calculation is 12/7. Answer: \boxed{\frac{12}{7}}.

Answer 27

To simplify the fractions, we need to convert them to mixed numbers.

1. To convert 1 27/42 to a mixed number, multiply the whole number (1) by the denominator (42) and add the numerator (27). This gives us 1 * 42 + 27 = 42 + 27 = 69. So, 1 27/42 simplifies to 69/42.

2. To convert 1 13/21 to a mixed number, multiply the whole number (1) by the denominator (21) and add the numerator (13). This gives us 1 * 21 + 13 = 21 + 13 = 34. So, 1 13/21 simplifies to 34/21.

3. To convert 1 33/42 to a mixed number, multiply the whole number (1) by the denominator (42) and add the numerator (33). This gives us 1 * 42 + 33 = 42 + 33 = 75. So, 1 33/42 simplifies to 75/42.

4. To convert 1 19/48 to a mixed number, multiply the whole number (1) by the denominator (48) and add the numerator (19). This gives us 1 * 48 + 19 = 48 + 19 = 67. So, 1 19/48 simplifies to 67/48.

Therefore, the fractions in simplified form are:
1. 69/42
2. 34/21
3. 75/42
4. 67/48

Answer 28

To find the elevation of the balloon when it passes over the school, we need to calculate the net change in elevation.

The balloon starts at an elevation of 1,100 feet.

It then descends 500 feet, so the elevation becomes 1,100 - 500 = 600 feet.

Next, it rises 950 feet from the previous elevation of 600 feet, so the elevation becomes 600 + 950 = 1,550 feet.

Finally, it descends 375 feet from the previous elevation of 1,550 feet, so the final elevation is 1,550 - 375 = 1,175 feet.

Therefore, the elevation of the balloon when it passes over the school is 1,175 feet. Answer: \boxed{1,175 \text{ feet}}.
