What phrase best describes a rhombus

jolli1 [7]

B should be the answer but don't hold that to me. I say B because a rhombus only has two parallel sides which are the top and bottom lines.

Renu had one CFL and one LED bulb. The CFL is of 8W. If the ratio of the power consumption of the LED bulbs to the CFL bulb is 3

sveta [45]

Answer:

x = 12W

Step-by-step explanation:

Let x = power consumption of the LED bulbs.

Writing the ratio as a fraction;

$\frac{LED}{CFL} = \frac{3}{2} = \frac{x}{8}$

Cross multiplying, we have;

$24 = 2x$

$x = \frac{24}{2}$

x = 12

Therefore, the power consumption of the LED bulbs is 12W.

x = 12W

Step-by-step explanation:

Let x = power consumption of the LED bulbs.

Writing the ratio as a fraction;

$\frac{LED}{CFL} = \frac{3}{2} = \frac{x}{8}$

Cross multiplying, we have;

$24 = 2x$

$x = \frac{24}{2}$

x = 12

Therefore, the power consumption of the LED bulbs is 12W.

Ratio; $\frac{LED}{CFL} = \frac{3}{2} = \frac{24}{8}$

The table shows the height of a softball that Hallie threw in the air. Is the relationship shown linear? Why or why not?

andrew11 [14]

Answer:

Not a linear relationship

Step-by-step explanation:

Given

The attached table

Required

Linear or not

To do this, we simply calculate the slope of the table at different intervals.

Slope (m) is calculated as:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

Let:

$(x_1,y_1) = (0,0)$

$(x_2,y_2) = (0.5,7.2)$

So, the slope is:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{7.2 - 0}{0.5-0}$

$m = \frac{7.2}{0.5}$

$m = 14.4$

Let:

$(x_1,y_1) = (1,10.7)$

$(x_2,y_2) = (2,12.2)$

So, the slope is:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{12.2 - 10.7}{2 - 1}$

$m = \frac{1.5}{1}$

$m = 1.5\\$

See that the calculated slopes are not equal.

Hence, it is not linear
