Lewis County, Washington, has a guideline that new roads should not exceed a 15% grade, or a 15 foot rise over a horizontal dist

ance of 100 feet. A proposed roadway rises 41 feet over 254 feet horizontally. Find the grade of the proposed roadway to the nearest percent. Does it meet the county’s guideline?

To calculate this problem, divide the smaller number by the larger to get the grade or slope.
I.E.  15/100= .15 = 15%
     41/254 = .16 = 16%   NOPE, it doesnt meet county guidelines

    hope it helps

Find the length of side a in simplest radical form with a rational denominator.
Goshia [24]

Answer:

x = 5.5

Step-by-step explanation:

Using a trig ratio, you can use sin, which is opposite over hypotenuse. sin(30)\textdegree=\frac{x}{11}

Now, multiply both sides by 11

11\cdot sin(30)\textdegree=x

this simplifies to x = \frac{11}{2} or 5.5.

Since sin30 is \frac{\pi}{6} radians, it can be written as \frac{11\pi}{6}.

You are installing new carpeting in a family room. The room is rectangular with dimensions 20 1/2 feet × 13 1/8 feet. You intend
disa [49]

Answer: 1. When you estimate, it is not an exact measurement. 3ft 8 in gets rounded to 4ft and 12 ft 3 in rounds to 12ft. now find the perimeter. P=2l+2w P= 2*12 +2*4 P=32feet

2. 3ft 8in = 3 8/12 or reduced to 3 2/3  12ft 3in = 12 3/12 or reduced to 12 1/4   The fractional part is referring to a fraction of a foot.

3. The perimeter of the room is P=2l+2w or P=2(12 1/4) + 2(3 2/3) p=24 1/2 + 7 1/3  P= 31 5/6 feet

4. The estimate and the actual are very close. They are 1/6 of a foot apart.

5a. Total baseboard 31 5/6ft - 2 1/4 ft = 29 7/12 feet needed.

5b. Take the total and divide it by 8ft  = 29 7/12 divided by 8= 3.7  You are not buying a fraction of a board so you would need 4 boards.
