I'd like to know the 'right' answers when you get told those two (19 and 20) are right.
Maybe we'll then understand the mind of your teacher.

1. (x^3)^5
A x^-15
B x^2
C x^8
D x^15
E x^-2
F x^-8
#1- (D)
because (x^3)^5=
(x^3)*(x^3)*(x^3)*(x^3)*(x^3)=
(x*x*x)* (x*x*x)*
(x*x*x)*(x*x*x)*(x*x*x)=x^15
14. Examine the following solution to a conversion problem. Do you see a mistake? If so, identify the location of the first mistake and explain why it is incorrect.
A The conversion is not possible.
B The first problem occurs in column (1). The problem should begin with mg.
C The first problem occurs in column (2). 1 kg is not equal to 1000 g, so that should not be used as the conversion factor.
D The first problem occurs in column (2). The conversion factor is upside down (grams should be on top, and kg should be on bottom).
E The first problem occurs in column (4). The multiplication and division was performed incorrectly.
F No mistakes.
#14- is (d) because every gram is made up of 1000 milligrams 3.25 kilograms is equal to 3250 grams each of them is made up of 1000 milligrams so there are 3250 *1000=3250000
3.25 kilograms *1000= 3250 grams
the chart says 1 kilogram =1000 grams
so to get the number of grams from 3.25 kilograms i would multiply 3.25 kilograms *1000=3250
so my answer for that would be d The first problem occurs in column (2). The conversion factor is upside down (grams should be on top, and kg should be on bottom
17. Examine the following solution to a conversion problem. Do you see a mistake? If so, identify the location of the first mistake and explain why it is incorrect.
A No mistakes.
B The conversion is not possible.
C The first problem occurs in column (1). The problem should begin with L.
D The first problem occurs in column (4). The multiplication and division was performed incorrectly.
E The first problem occurs in column (3). We are not allowed to use a conversion factor of (1 L/ 1L).
F The first problem occurs in column (2). 1 L is not equal to 1000 kL, so that should not be used as the conversion factor.
#17-is F because 1kl=1000 l
not the other way around
19. Estimate the amount of juice in a typical orange juice carton in liters.
A about 8 liters
B about 5 liters
C about 4 liters
D about 3.5 liters
E about 2 liters
F about .5 liters
#19-D
i estimated it as D from a 1 liter carton that i have in the fridge
20. Estimate the weight of a small can of soup in grams.
A about 30 grams
B about 500 grams
C about 250 grams
D about 325 grams
E about 750 grams
F about 100 grams
#20- B
because a gram measures the weight of very light objects so i estimated it to be 500 grams from the can of soup that was in my refrigerator
thats the answers i submitted to her

hi zee-f
You're welcome. Thanks for supplying the final answers.
Hope the next topic is more straight forward, but post again if you need to.
