Question 1:

If the temperature is dropping at a rate of 6 degrees per hour. How many hours will it take for the temperature to drop 30 degrees?

Solution:

As given in the question,

The rate at which the temperature is dropping = 6 degrees per hour.

To find the hours it takes to drop the temperature to 30 degrees, we have to go for the division law of integers.

Therefore, change in temperature = -30/-6

= 5 hours

Thus, it takes 5 hours for the temperature to drop by 30 degrees per hour.

The final solution is 5 hours

Question 2:

If a stock is losing value at a rate of \$8 per day. How many days before the stock has lost a value of \$48?

Solution:

The rate at which the stock is losing value = \$8

To find the days that stock lost the value = \$48, we have to apply the division of integers.

Therefore, no of days = -48/-8 = 6

Thus, it takes 6 days before the stock has lost the value of \$48.

The final solution is \$48

Question 3:

If a group of hikers is descending at a rate of 15 feet per hour down a mountain. How many hours will it take for the group of hikers to descend 105 feet?

Solution:

The rate at which the hikers are descending = 15 feet per hour

To find time for a group of hikers to descend 105 feet, we apply the law of division.

Therefore, the time = -105/-15 = 7

Hence, the group of hikers descend 15 feet in 7 hours.

The final solution is 7 hours

Question 4:

If a bucket full of water is evaporating at a rate of 3 cm per hour. How long before the bucket has evaporated a total of 18cm?

Solution:

The rate at which the bucket full of water is evaporated = 3 cm per hour

To find the time of the bucket evaporated a total of 18cm, we apply the division of integers.

Therefore, the total time = -18/-3 = 6

Thus, it takes 6 hours for the bucket to evaporate 18cm.

Hence, the final solution is 6 hours.

Question 5:

The product of 2 integers is 270. If one of the integers is (-18). Find the other one?

Solution:

Let the other integer be x

As given in the question, the product of 2 integers is 270

x * (-18) = 270

x = 270/18

x = -15

Therefore, the final solution is -15

Question 6:

Find an integer which when multiplied by 4 and then divided by 9 becomes (-28)?

Solution:

Let the integer be x

x * 4 / 9 = -28

4x / 9 = -28

4x = -28 * 9

x = -28 * 9 / 4

x = -63

Therefore, the integer which when multiplied by 4 and then divided by 9 becomes (-28) is -63

Question 7:

If the quotient obtained on dividing on integer by -9 is 8, Find the integer?

Solution:

Let the integer be x

x / -9 = -8

x = -8 * -9

x = 72

Question 8:

A shopkeeper earns a profit of Rs 1 on selling one pen and suffers a loss of 30 paise on selling one pencil in a particular month, he incurs a lot of Rs. 5. In that month, he sold 40 pens. How many pencils did he sell in that period?

Solution:

Let the no of pencils he sell in that month be x

No of pens he sell in that month = 40

40 * (1) + x * (-30/100) = -5

40 – 3x/10 = -5

40 + 5 = 3x/10

45 = 3x/10

x = 10 * 45/3

x = 150

Question 9:

The population of a small town is changing at rate of -255 people per year. How long will it take for the change in population to be -2040 people?

Solution:

The rate of the population changing per year = -255

To find the change in population to be -2040 people, we have to apply division rule.

Therefore, the years for the change of population = -2040/-255 = 8

Hence, the total years = 8 years

The final solution is 8 years.

Question 10:

During a six-hour period, the temperature dropped 18 degrees. How much did the temperature change per hour?

Solution:

Time of the period = 6 hours

Drop in the temperature = 18

To find the temperature change, apply the division rule.

Therefore, the total change = -18/6 = -3 degree

Hence, the temperature changed by 3 degrees per hour.

Question 11:

A stock decreased in value by \$80 during the five days. How much did the stock decrease each day?

Solution:

As given in the question,

The value at which the stock decreased = \$80

No of days = 5

To find the stock decreased each day we apply division of integers.

Therefore, the stock decreased = -80/5 = -16

Question 12:

The outside temperature is -20degree F and rising at a rate of 5 degrees per hour. How long will it be before the temperature reaches 0 degrees F?

Solution:

The temperature outside = -20 degree F

The rate of rising the temperature = 5 degrees per hour

To find how long will it be before the temperature reaches 0 degrees F, we apply the division of integers.

Therefore, the time taken = 20/5 = 4

Hence, it takes 4 hours to reach 0 degrees F

Question 13:

Judges in some figure skating competitions must give a mandatory 5 point deduction for each jump missed during the technical part of the competition. Marisa has participated in 5 competitions this year and has been given a total of -20 points for jumps missed. How many jumps did she miss?

Solution:

Total no of points = -20

No of participants in the competition = 5

Therefore, total number of jumps missed = -20/(-5) = 4 jumps

The final solution is 4 jumps

Question 14:

Miranda is an excellent spinner who averages +3 points on her spins during competitions. Last year her total spin points equaled +21.

About how many spins did she successfully complete?

Solution:

No of average spins = 3

Total spin points = 21

Therefore, no of spins she completed = 21/3 = 7 spins

Hence, the final solution is 7 spins.

Question 15:

The temperature dropped 32 degrees F in 4 hours. Suppose the temperature dropped by an equal amount each hour. What integer describes the change?

Solution:

As given in the question,
Temperature drop = 32 degrees F
Time taken = 4 hours

Therefore, to find the integer that describes the change, we apply the division rule.

Hence, the time taken in 4 hours = -32/4 = -8 degrees F

The final solution is -8 degree F

Question 16:

A stock market fell 60 points over a period of 4 days. What was the average change in the stock market per each day?

Solution:

As given in the question,

No of points fell in stock market = 60

Time of period = 4 days

To find the average change in the stock market per day, we apply the division method.

Therefore, the average change = 60/4 = -15

Hence, the final solution is every 15 points change in the stock market per day.

Question17:

In a lab, a substance was cooled by 36 degrees over a period of 6 hours at a constant rate. What was the change in temperature each hour?

Solution:

As given in the question,

The temperature at which it was cooled = 36 degrees

Period of time = 6 hours

To find the change in temperature each hour, we apply the law of division rule.

Therefore, the change in temperature = 36/6 = 6

Hence, for every hour there will be a change of 6 degrees.

Thus, the final solution is 6 degrees.

Question 18:

The outside temperature is -20 degrees F and raising at the rate of 5 degrees per hour. How long will it be before the temperature reaches 0 degrees F?

Solution:

As per the given solution,

The outside temperature = -20 degree F

The rate at which the temperature is rising = 5 degrees per hour

To find the temperature to reach 0 degrees F, we apply the division law of integers

Therefore, the change in temperature = 20/5 = 4 hours

Hence, it takes 4 hours before the temperature reaches 0 degree F

Thus, the final solution is 4 hours

Question 19:

Judges in some figure skating competitions must give a mandatory 5 point deduction for each jump missed during the technical part of the competition. Marisa has participated in 5 competitions this year and has been given a total of -20 points for jumps missed. How many jumps did she miss?

Solution:

As given in the question,No of deduction points = 5 pointsNo of competitions Marisa participated in = 5Total points for jumps missed = -20

To find the jumps she missed, we apply the division rule.

Therefore, the jumps missed = -20/-5 = 4

Hence, Marisa missed 4 jumps in 5 competitions

Thus, the final solution is 4 jumps.

Question 20:

Mirinda is an excellent spinner who average +3 points on her spins during competitions. Last year her total spin points equaled +21. About how many spins did successfully complete?

Solution:

As given in the question,

The average points on spin = +3

Total points equalled = +21

To find the spins that successfully completed, we apply the division law of integers.

Therefore, the spins completed = 21/3 = 7

Thus, the final solution is 7 spins.
