ANSHS Grade 7 Fourth Grading Exam

Here is the questionnaire administered for the the grade 7 of Alabel National Science High School for Fourh Grading period.

Work Problem No. 2

Greg can milk all of the carabaos in 120 minutes and Harold can do it in 60 minutes. If Greg milks for 20 minutes before Harold joins him, how long would it take them to finish?

Solution:

Let x be the length of time Greg and Harold can finish milking the carabaos.

                  Rate (job per minute)     Time                  Work
Greg                   1/120                   x + 20         ( x + 20 ) / 120
Harold                1/60                         x                       x/60

Equation:    ( x + 20 ) / 120  +  x/60  =  1

To solve, multiply both sides of the equation by the LCD, i.e.

                                        120 ( ( x + 20 ) / 120  +  x/60 )  = ( 1 ) 120
                                                                      x + 20 + 2x  =  120
                                                                            3x + 20  = 120
                                                                                     3x  =  120 - 20
                                                                                     3x  =  100
                                                                                       x  =  100/3
                                                                                       x  =  33 1/3  minutes  or 13 minutes and 20 seconds.

Therefore, Greg and Harold can milk all the carabaos in 13 minutes and 20 seconds.

Work Problem No. 1

Dan can do the job in 30 hours, Ellen can do it in 40 hours, and Francis can do it in 60 hours. how long would it take them if they work together?

Solution:

Let x be the number of hour Dan, Ellen, and Francis take if they work together.

Name                Rate (job per hour)         Time                  Work
Dan                             1/30                       x                         x/30
Ellen                            1/40                       x                         x/40
Francis                        1/60                       x                         x/60

Equation:              x/30  + x/40  +  x/60  =  1

To solve, multiply both sides of the equation by the LCD, i.e.

120 (  x/30  + x/40  +  x/60 ) = ( 1 ) 120
                      4x  + 3x  + 2x  =  120
                                        9x  =  120
                                          x  =  120/9
                                          x  =  13 1/3 hours or 13 hours and 20 minutes.

Therefore, Dan, Ellen, and Francis can finish the job in 13 hours and 20 minutes if they work together.

Problem Set #1: SETS

A. Use the Roster Method to specify the sets of in Problems 1 through 5.
1. The fractions whose numerator is 1, and whose denominator is a counting number less than 10
2. The single digits used in the decimal system
3. The colors of the rainbow
4. The set of first 10 prime numbers
5. The months of the year

B. Write the cardinality of the sets in Problems 1 through 5.

C. The subsets of a set is given by the formula 2^n (read as "2 raised to n" or "2 raised to the power of n"), where n is the cardinality of the set. For example, the set {a, b, c} has 2^3 = 2x2x2 = 8 subsets, i.e., {{a,b,c},{a,b},{a,c},{b,c},{a},{b},{c},{Ø}}.
Find all the subsets of the set {l,o,v,e}.

D. If U = {x|x is a letter in the the English Alphabet}
   A = {x|x is a or one of the next four letters in the English alphabet}
     = {a,b,c,d,e}
   E = {x|x is e or one of the next four letters in the English alphabet}
   I = {x|x is i or one of the next four letters in the English alphabet},
