The answer is 4/16. The fastest way to solve these sorts of equations is to remember that a fraction is merely a division problem. Take the top number (numerator) and divide it by the bottom number ( denominator). That will give you a decimal. 4/16 is equal to .25. 5/20 is also equal to .25. You could also go about it by reducing the fraction. 5 goes into 20 4 times 5 goes into itself 1 time. so you have 1/4. 4 goes into 16 four times and into itself once. It is also 1/4. I hope this helps. :)

3 cups left.

David biked a total of 158 miles (option C)

Why?

- First exercise:

To solve the problem we need to consider that for each 1/2 cup of cornmeal, we will have 6 corn muffins.

So, calculating we have:

$TotalMuffins=24=4*6\\\\UsedCups=\frac{1}{2}*4=2Cups$

We can see that, if each 1/2 cups can give us 6 corn muffins, 2 cups can give us 24 corn muffins.

$CupsLeft=5cups-2cups=3cups$

Hence, there are 3 cups left.

- Second exercise:

We can solve the problem by multiplying or adding the fractions according to the number of dots assigned to each one.

So, calculating we have:

$FirstDay=10miles*2=20miles\\SecondDay=10\frac{1}{2}miles=10.5miles\\ThirdDay=11miles*3=33miles\\FourthDay=11\frac{1}{2}miles*4=11.5miles*4=46miles\\FifthDay=12miles*3=36miles\\SixthDay=12\frac{1}{2}miles=12.5miles$

$Total=20miles+10.5miles+33miles+46miles+36miles+12.5miles\\Total=158miles$

Hence, we have that David covered a total 158 miles. (Option C)

Have a nice day!

Answer:

graph C

Step-by-step explanation:

Well I lik it spread out cause you get more information and you can tell how the data is aligned and not scrunched up. Since the example said that the explanatory variable (indepdent variable) is best on the X axis, only C and A are left. A is all scrunch’s up and data could be read worng, but C is nice and spread and it shows all the data and rating clearly

Is each line parallel, perpendicular, or neither parallel nor perpendicular to a line whose slope is −34?

Zigmanuir [339]

Given:

The slope of a line is $-\dfrac{3}{4}$ .

To find:

The lines in the options are parallel, perpendicular or neither parallel nor perpendicular to the given line.

Solution:

We know that the slopes of parallel lines are equal.

The slope of line Q and the slope of given line are same, i.e., $-\dfrac{3}{4}$ . So, the line Q is parallel to the given line.

The slope of a perpendicular line is the opposite reciprocal of the slope of the line because the product of slopes of two perpendicular lines is -1.

The slope of a line is $-\dfrac{3}{4}$ . It means the slope of the perpendicular line must be $\dfrac{4}{3}$ . So, the line N is perpendicular to the given line.

The slopes of line M and P are neither equal to the slope of the given line nor opposite reciprocal of the slope of the line.

Therefore, the lines M and P are neither parallel nor perpendicular.
