Well, a rational decimal is like a simple 3.1 or 4.5. It just cuts off easily. Another example would be a repeating decimal like 3.333333...


An irrational decimal is like 3.1415682983523576294875 with no pattern or cutoff point.


Sorry if I am wrong.

I need the surface area for this prism. If you could provide a formula too, that would be great!
avanturin [10]

Answer:

136 m^{2}

Step-by-step explanation:

Back of the shape area/ front of the shape area

A = \frac{1}{2} (bh)

A = \frac{1}{2} (6 × 4)

A = \frac{1}{2} (24)       Divide 24 ÷ 2

A = 12

Bottom of the shape area

A = l · w

A = 7 · 6

A = 42

Left side of the shape area/right side of the shape area

A = l · w

A = 7 · 5

A = 35

---------------------------------------------------------------------------------

35 + 35 + 42 + 12 + 12 = 136 m^{2}

SA = 136 m^{2} Surface Area = 136 m^{2}

Given a dilation with the origin O (0, 0), by observation determine the scale factor "K."
BaLLatris [955]
When the dilation is about the origin, the scale factor multiplies every coordinate. That is (considering the x-coordinate) ...
  6·k = 3
  k = 3/6 = 1/2

The appropriate choice is
  1. 1/2

Rewrite the following equation in slope-intercept form. 6x − 14y = -3 Write your answer using integers, proper fractions, and im
Alex17521 [72]
Answer:
y = (3/7) x + (3/14)

Explanation:
The slope-intercept form has the following formula:
y = mx + c
where:
m is the slope
c is the y-intercept

The given is:
6x - 14y = -3

To get in the slope-intercept form, we need to isolate the y as follows:
6x - 14y = -3
14y = 6x + 3
y = (6/14)x + (3/14)
y = (3/7) x + (3/14)

Hope this helps :)

HELP QUICK PLEASE <br><br> In parallelogram JKLM, angle J is 35 degrees. Find angle .<br> M
frutty [35]

The angle M of the parallelogram is; ∠ M = 145°

<h3>What are angles in a parallelogram?</h3>

In a parallelogram, there are four angles with angles on the same line summing up to 180°.

Now, we are told that angle J is 35°. But angle M is on the same line as that of angle J and as such;

∠J + ∠ M = 180°

35° + ∠ M = 180°

∠ M = 180° - 35°

∠ M = 145°
