Answer: Option #4: the 0.2 could be changed to 2.

Explanation:

The table is designed to make the concept of percentages more understandable. The table first allocates the total amount of 70 in terms of its "fifths," or 20% parts. Then it expresses these parts in the last row of the table, showing that 20% of 70 is 14 and all the five parts sum up to 70 again.

Now, Mikel is supposed to express 40% of the amount. So she writes (incorrectly): 0.2 * 14. This statement needs to be changed to 2 * 14 (two times 14 = 28), to correspond to 2 times 20%, or 40%  of 70.

This is reflected in the last (fourth) option "The 0.2 in the expression could be changed to 2."

Option #3 is incorrect because changing 14 to 70, will result in an incorrect number (2.8).

Options 1 and 2 are similarly incorrect (as can be easily verified)

Need help quick please!!!<br> Could you please explain the answers to both questions? Thanks!

For the triangle picture:

2/6 = 5/x

2x = 30

x = 15


For the other picture:

3.2/2 = a/8

The third option applies.


Other option does not apply.
Because for Option 4,
It should be 2/3.2 = b/6.4

For option 3,
it should be b/6.4 = 5/8

Jim's work evaluating 2 (three-fifths) cubed is shown below. 2 (three-fifths) cubed = 2 (StartFraction 3 cubed Over 5 EndFractio
sammy [17]

Answer:

Jim's error is " He did not multiply Three-fifths by 2 before applying the power "

Step-by-step explanation:

Jim's evaluating expression is 2(\frac{3}{5})^3

To verify Jim's error :

Jim's steps are

2(\frac{3}{5})^3

=2(\frac{3^3}{5})

=2(\frac{3\times 3\times 3}{5})

=2(\frac{27}{5})

=\frac{54}{5}

Therefore 2(\frac{3}{5})^3=\frac{54}{5}

Jim's error is " He did not multiply Three-fifths by 2 before applying the power "

That is the corrected steps are

2(\frac{3}{5})^3

=2(\frac{3^3}{5^3})  ( using the property (\frac{a}{b})^m=\frac{a^m}{b^m} )

=2(\frac{3\times 3\times 3}{5\times 5\times 5})

=2(\frac{27}{125})

=\frac{54}{125}

2(\frac{3}{5})^3=\frac{54}{125}
