Determine whether the following statement is always, sometimes, never true. Justify your reasoning.If the scale factor of a scale drawing is greater than one, the scale drawing is larger than the actual object.

Answers

Answer 1

Answer: The statement 'If the scale factor of a scale drawing is greater than one, the scale drawing is larger than the actual object.' is always true. If the scale factor of scale drawing is larger than one, the dimensions of the drawing are multiplied by that number. The only way that it would not be larger would either be if the scale factor is not larger than one or if the dimensions of the drawing are negative. However, since the dimensions of a drawing cannot be negative and the scale factor will be greater than one (in this example) the statement is always true.

Mrs. Rowan allotted 30 minutes at the beginning of class for her students to complete an exam. The last student took 42 minutes to complete the exam. What is Mrs. Rowan's percent error?

Answers

Using percentage concepts, it is found that Mrs. Rowan percent error is of 40%.

The percent error is given by the extra time afforded multiplied by 100% and divided by the allotted time.

In this problem:

Allotted time of 30 minutes.
The last student took 42 minutes to complete the exam, thus the extra time afforded was of 12 minutes.

The percent error is:

$P = (12)/(30) * 100\% = 0.4 * 100\% = 40\%$

The percent error is of 40%.

A similar problem is given at brainly.com/question/16903296

Step-by-step explanation:

Percent error = |actual − theoretical| / actual × 100%

|42 − 30| / 42 × 100% = 28.6%

3/4 (4c + 16) = 2c ÷ 9. what is c

Answers

Distribute

(3/4)(4c)+(3/4)(16)=2c/9

3c+12=2/9 c

Now subtract 2/9 c from both sides

3c+12-2/9 c=2/9 c-2/9 c

25/9 c+12 =0

Now we need to subtract 12 from both sides

25/9 c+12-12=0-12

25/9 c=-12

Just multiply both sides by 9/25 so we find the value for c

25/9 *(25/9 c)=-12(9/25)

c= -108/25
