Correct Answer is D
Explanation
To find the greatest number from the given options, convert the decimal numbers into fractions.
6.98 becomes 698/100
9.2 becomes 92/10
The least common denominator for the denominators of 7, 100 and 10 is 700. Now we can multiply each fraction with 700 as follows:
3/7*700=300
698/100*700=4886
10/7*700=1000
92/10*700=6440
In order from the smallest to largest, we organize the number set as follows:
3/7, 10/7, 6.98, 9.2.
Thus, 9.2 is the greatest of all.
Correct Answer is C
Explanation
We follow the order of operations to solve the given expression. The order of operations is PEMDAS:
- Parentheses
- Exponents
- Multiplication and Division (in order from left to right)
- Addition and Subtraction (in order from left to right)
First, we start with the numerator and solve it as follows
[3(6+5*4)]
We start with multiplication in parenthesis, 5*4=20. The expression becomes
[3(6+20)]
Then, we conduct the addition in parenthesis 6+20=26. Then, the expression becomes
[3(26)]=3*26=78
Now, we solve for denominator, which is 26/2=13.
Thus, the expression is reduced into

The expression reduces into 6.
Correct Answer is B
Explanation
To find the circumference of a circular garden, we can use the formula:
C=π×d
Where:
- C = Circumference
- π = 3.14 (as given)
- d = Diameter
Step 1: Substitute the given values into the formula
The diameter d is 14 metres, so:
C=3.14×14
Step 2: Perform the multiplication
C=43.96 metres
Final Answer:
The circumference of the garden is 43.96 metres.
The correct answer is B. 43.96 metres.
Correct Answer is A

Explanation
The polling organization has an average ratio of 2 answered calls for every 15 attempted calls. To find the expected number of answered calls for 150 attempted calls, we can set up a proportion based on this ratio.
Step 1: Set up the proportion
The ratio of answered calls to attempted calls is:
=
Where x is the number of expected answered calls for 150 attempted calls.
Step 2: Solve for x
Cross-multiply to solve for x:
2×150=15×x
300=15x
X =
x = 20
Conclusion:
The expected number of answered calls for 150 attempted calls is 20 calls.
The correct answer is C. 20 calls.

We are asked to find the number of students enrolled in the radiologic program using the information provided on the pie chart.
If we let x represent the number of students enrolled in the radiologic program, we set a proportion equation with number of students on the numerator and percentages on the denominator.
Total percent in the pie chart adds to 100%, which equals 1200 students. Then, 21% will represent

We solve the value of x by cross-multiplying the equation above.

Therefore, 252 students will enroll for a radiologic program.
