If a shirt costs $25 and is discounted by 20%,.
Question
- A. $20
- B. $15
- C. $25
- D. $30
View Answer
Correct Answer ( A )
A 20% discount means that the price is reduced by 20% of the original price . Calculate the discount amount first: 20% of $25 is (20/100) * $25 = $5. Then subtract the discount from the original price of $25 — $5 = $20. The final price of the shirt after the 20% discount is $20. Percentage calculations are commonly used in everyday life, from calculating sales tax to understanding interest rates .
A rectangle has a length of 15 cm and a.
Question
- A. 23 square centimeters
- B. 120 square centimeters
- C. 110 square centimeters
- D. 240 square centimeters
View Answer
Correct Answer ( B )
The area of a rectangle is calculated by multiplying its length by its width , in this case the length is 15 cm and the width is 8 cm , thus the area is 15 cm * 8 cm = 120 square centimeters. This simple formula is applicable to numerous real-world scenarios , from calculating the space required for flooring to designing architectural structures .
What is the value of 3/5 + 2/3? | denominator.
Question
- A. 1/8
- B. 19/15
- C. 5/8
- D. 11/15
View Answer
Correct Answer ( B )
We need a common denominator to add fractions, the least common multiplier of 5 and 3 is 15. We rewrite the fractions with the denominator of 15: (3/5) * (3/3) = 9/15 and (2/3) + (5/5) = 10/15 . Now we can add them: 9/15 + 10/15 = 19/15. This can also be expressed as a mixed number: 1 and 4/15.
If a train travels 120 miles in 2 hours, what.
Question
- A. 30 miles per hour
- B. 60 miles per hour
- C. 120 miles per hour
- D. 240 miles per hour
View Answer
Correct Answer ( B )
To calculate average speed, we divide the total distance traveled by the total time taken . In this case the train travels 120 miles in 2 hours , therefore the average speed is 120 miles / 2 hours = 60 miles per hour . Average speed is a fundamental concept in physics and is crucial for understanding motion and solving related problems . This calculation assumes a constant speed throughout the journey , in reality the train speed may vary .
