I find it easier to do the actual computation than to try to choose the correct answer from a bunch of alternatives.

You are given the area of a rectangle, as well as the length of one side. To find the length of the other side, you must divide the given side length into the area.

Thus, the unknown side length is

1.403E(-2) cm^2
----------------------- = 0.23E2 cm, or, better, 2.3E1, or 23 cm
6.1E(-4) cm

Now that you have this info, which of the given four steps do you judge to be appropriate and which inappropriate?

What does the word “flip” tell you to do in “keep change flip” for dividing fractions a) change the place of the numbers numerat

mars1129 [50]

Answer:

b) change the places of the numbers in the numerator and the denominator for the second fraction

Step-by-step explanation:

In the phrase "keep change flip":

You "keep" the first fraction.

"Change" the division sign into a multiplication sign.

"Flip" (or switch) the places of the numerator and denominator in the second fraction.

Example:

$\frac{1}{2}$ ÷ $\frac{1}{3}$

$\frac{1}{2}*\frac{3}{1}=\frac{3}{2}=1.5$

Hope this helps.

Select the statement in if-then form.

The correct statement is C. If an angle is an acute angle, then the angle measures less than 90 degrees.
A and B are obviously incorrect, and D is incorrect because it can be other angle as well, not just acute.
