A farmer grows apple, orange, lemon, banana, and pear trees. The number of trees planted this year is shown in table above. Which of the following would best display the data? Tree type Apple Orange Lemon Banana Pear Number of trees 20 10 12 25 21

A. Bar graph

B. Stem and leaf plot

C. Line graph

D. Scatter plot

Answer Explanation:

Based on the above data, the horizontal axis will be tree type and vertical axis will represent the number of trees.

Based on these, a bar graph is appropriate to represent the number trees.

Therefore, the Correct Answer is A.

Q #1: A bucket can hold 3 L. How many ml can the bucket hold?

A. 3000 mL

B. 300 mL

C. 30 mL

D. 0.003 mL

Answer Explanation

to change L to mL we use the following options of interconversions:

Or

Since we are needed to change L to mL, use the second option.

Thus, a bucket can hold 3000 mL which is equal to 3 L.
Q #2: One gallon of cleaning solution requires 6 oz of ammonia. If the maintenance department needs 120 gallons of solution to clean all of the floors, how much ammonia is needed?

A. 20 gallons

B. 720 gallons

C. 20 oz

D. 720 oz

Answer Explanation

we use given information to find how much ammonia is need to make the specified solution.

We are told, one gallon of cleaning solution requires 6 oz of ammonia. In other words, we can express this as:

1 gallon of solution6 oz of ammonia

Or

6 oz of ammonia1 gallon of solution

Since we are needed to find how much ammonia is needed, we use the second option to find how much ammonia is required by 120 gallons of solution.

From the above equation, gallon of solution will cancel, and oz of ammonia is left.

Therefore, the solution will require 720 oz of ammonia.
Q #3: Five less than twice a number Which of the following translates the phrase above into a mathematical expression?

A. 5x-2

B. 2-5x

C. 5-2x

D. 2x-5

Answer Explanation

we need to form a mathematical expression from the given word problem.

Let the number be x.

Twice a number=2x

Five less than twice a number=2x-5

So the mathematical express from the word problem is 2x-5
