Leto [7]3 years ago

Using the slope formula, it is found that the slope is of <u>0.09375 < 0.1</u>, hence, it meets the requirements.

The slope of a ramp is given by it's height divided by it's length, that is:

m = \frac{h}{l}

In this problem:

  • The height is of 75 cm, hence h = 75.
  • The length is of 800 cm, hence l = 800.

Then, the <em>slope </em>is given by:

m = \frac{h}{l} = \frac{75}{800} = 0.09375

The slope is of <u>0.09375 < 0.1</u>, hence, it meets the requirements.

A similar problem about the use of slopes in ramps is given at brainly.com/question/18090623

A transformation of ΔDEF results in ΔD'E'F'.
sladkih [1.3K]

Answer:

Rotation

Step-by-step explanation:

A transformation of a triangle can be either dilation or reflection or rotation or a translation.

Dilation happens when a symmetric figure is formed with scale factor other than 1.  But here both triangles have same side length.  Hence no dilation

Reflection happens when it is reflected over a line as we see in a mirror. But here the two triangles are not looking as images on  a line.  Hence no reflection

Rotation is keeping the same shape but rotating through a certain angle.  Here DEF is rotated without disturbing its shape or size through a certain angle. Hence rotation is right

Translation is not right because there is no vertical or horizontal shift to get new triangle.

Which of the following equations has a solution of x = -5?
Anna [14]

Answer:

C)

Step-by-step explanation:

16x - 7 = 11x - 32

16x - 11x = -32 + 7

5x = -25

x = -5

__________________________________________________

-4x - 10 = 2x + 20

-4x - 2x = 20 + 10

-6x = 30

x = -5
