If you would have to graph x=7, you probably know that this is a vertical line at, well, x=7.

| x | = 7 is nothing more than two vertical lines, namely x=7 or x=-7, as you already wrote down.

| x | = -8 has no (real) solutions, so there is nothing to graph.

Suppose a new regulation that a maximum angle of a ramp for a wheelchairs is 8°. At least how long must the new ramp be? Round t
Llana [10]

Answer:

The length of the ramp is at least 17.2 feet

Step-by-step explanation:

See attachment for the appropriate diagram.

The length of the ramp is represented with z

So, we have:

\theta = 8

BC = 2.4

Required

Find z

To find z, we make use of sine formula:

sin\theta = \frac{BC}{z}

Make z the subject

z= \frac{BC}{sin\theta }

So:

z= \frac{2.4}{sin(8)}

z= \frac{2.4}{0.1392}

z= 17.2ft

<em>The length is at least 17.2 feet</em>

Help with this question please. Doesn't make sense at all.​
snow_lady [41]

Answer:

  a. FG ≈ 6.983 cm

  b. FH = 13.16 cm

Step-by-step explanation:

<h3>a)</h3>

Corresponding sides of similar triangles are proportional. This means ...

  FG/GH = CD/DE

  FG = GH(CD/DE) = (9.4 cm)(2.6/3.5) . . . . . . multiply by GH; fill in values

  FG ≈ 6.983 cm

__

<h3>b)</h3>

And ...

  FH/GH = CE/DE

  FH = GH(CE/DE) = (9.4 cm)(4.9/3.5)

  FH = 13.16 cm

__

<em>Additional comment</em>

Corresponding vertices are listed in the same order in the similarity statements. This means, for example, segment FG (which names the first two vertices in the name of ΔFGH) will correspond to segment CD (which names the first two vertices of ΔCDE).

Find the area of a floor that measures 12.75 ft. by 10.5 ft. 133.875 11.775 11.875 132.875
kompoz [17]
133.875
This is the answer because we are given the length and the width of this floor. We are assuming it is a regular rectangle.
So we just multiply the length and the width which is 12.74 x 10.5, which comes out to 133.875

ra1l [238]
She earns $5.50 for every hour so:
m = 5.5h
3 hours and 45 minutes is 3.75 hours.
m = 5.5(3.75)
m = 20.625
After rounding, she earns $20.63.
