Answer:
8 questions each for short answer questions and 8 questions of Multiple Choice Questions type.
A total of 16 questions.
Step-by-step explanation:
Given:
The number of multiple choice questions and number of short answer type questions are same.
Let it be equal to .
Average Time taken to attempt multiple choice question = 2 minutes
Total time taken to attempt multiple choice question = 2 minutes
Average Time taken to attempt short answer type question = 3.5 minutes
Total Time taken to attempt short answer type question = 3.5
Total time for test should be less than 45 minutes.
Therefore, the equation becomes:
Hence, the value of
Therefore, the answer is:
8 questions each for short answer questions and 8 questions of Multiple Choice Questions type.
A total of 16 questions.
Total Weight = Weight of the book + Weight of the CD + Weight of the box
Total Weight = 1 1/4 pound + 1/5 pound + 3/10 pound
Total Weight = 5/4 + 1/5 + 3/10
To add these fractions, you need to put them over a common denominator. To do that, find the least common multiple of 4, 5, and 10. Below is a table of the multiples. The least multiple they have in common is 20, shown in orange. So use 20 as your least common denominator.
1 2 3 4 5 6 7
4 x 4 8 12 16 20 24 ...
5 x 5 10 15 20 25 30 ...
10 x 10 20 30 40 50 60 ...

23° 20' 48" in degrees
Minutes are 1/60 of a degree and seconds 1/60 of a minute.
Let's convert the 48" to minutes.
48/60 = 0.8
23° 20' 48" ⇒ 23° 20.8'
Let's convert the 20.8' to degrees.
20.8/60 ≈ 0.3466667
23° 20.8' ⇒ 23.35°
X + (-2) = 4...
do the inverse +2 on both sides 4+2 equals 6. X= 6
C=x.19+.25
C means the total cost
X means the extra minutes
