You're welcome. Thanks for supplying the final answers.

Hope the next topic is more straight forward, but post again if you need to.

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

]]>Maybe we'll then understand the mind of your teacher.

Bob

]]>post back to let me know.

Bob

]]>Now I am sure we've arrived at the right answer. F

Ok?

Bob

]]>Bob

]]>I've posted the original diagram and my answer.

edit!

The conversion is wrong because 1kL = 1000L not the other way round. That makes it answer F.

Does that make sense?

i answered D it was incorrect

so bob bundy helped me he said the error was in the second column i need help explaining why its in the second column,
