Answer:
Maximum slope for hand-propelled wheelchair ramps should be 1" of rise to every 12" of length (4.8 degree angle; 8.3% grade).
Maximum slope for power chairs should be 1.5" rise to 12" length (7.1 degree angle; 12.5% grade).
Minimum width should be 36" (inside rails) - (48" is ideal).
The "deck" or surface of the ramp should be set down between a side-rail assembly such that there is about a 2" curb or lip along the edges of the ramp surface. Decking could consist of 1" X 6" pressure treated pine, (or 3/4" pressure treated plywood applied to a frame).
If possible, the end of the deck (where it meets the lower ground surface) should be beveled to provide a smooth transition from the ramp to level ground. Alternatively, a sheet of 10 Ga. steel at least 10" long and sized to fit the width of the ramp could be used to span the space between the deck surface and the walk or driveway surface at the end of the ramp. This piece should overlap the ramp deck by 2" and be fastened securely with 4 large countersunk flat-head wood screws.
A level platform of at least 5' X 5' should be at the top of ramp to allow for wheelchair maneuvering. If the entrance way opens outward, there should be 1' of surface area extending from the side of the door opening to allow motion to the side without backing the chair during door opening. This landing should not be considered part of the overall "run"/length of the ramp. Any turning point along the ramp needs a level landing. If the turn is a right angle (90 degrees), the landing should be a minimum of 5' by 4'. If a "switchback" of 180 degrees is constructed, the level landing should measure at least 5' X 8'. Ramps longer than 30' should provide a platform every 30' for purposes of safety and to create opportunity for rest
Step-by-step explanation:
The length of the ramp nearest to the hundredth will be 12.04 feet.
What is a Pythagoras theorem?The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
A wheelchair slope that is developed to rise 1 foot off the ground should expand 12 feet along the ground.
The length of the ramp will be given as,
H² = P² + B²
H² = 12² + 1²
H² = 144 + 1
Simplify the equation further, then we have
H² = 145
H = √145
H = 12.04 feet
The length of the slope closest to the 100th will be 12.04 feet.

9. The sum of two consecutive integers is 41 less than
four times the larger. Find the numbers.
Answer:
19 and 20
Step-by-step explanation:
Let x be the larger number
x - 1 + x = 4x - 41
We can combine like terms and isolate x:
2x - 1 = 4x - 41
2x = 40
x = 20
20 - 1 = 19

I hope this helps you! Have a great day!
1/2h+1/3(h-6)=5/6h+2
Hey there! I'm happy to help!
First we use the distributive property to undo the parentheses.
1/2h+1/3h-2=5/6h+2
We combien like terms.
5/6h-2=5/6h+2
We subtract 5/6 h from both sides.
-2=2
There are no solutions because this equation is not true so therefore no possible x value can satisfy it.
Have a wonderful day! :D

Use the given conditions to write an equation for the line in point-slope form and general form. Passing through (-4,8) and parallel to the line whose equation is 3x-8y-7=0
Step-by-step explanation:
Hey there!
The equation of a st.line passing through point is;
(y - 8) = m1(x+4).........(i).
And another equation is;
3x - 8y - 7 =0.......(ii)
From equation (ii), we get;
[tex]slope(m2) = \frac{ - coeff. \: of \: x}{coeff. \: of \: y} [/tex]
[tex]m2 = \frac{ - 3}{ - 8} [/tex]
Therefore the slope is 3/8.
As they are parallel lines, their slopes are eaual.
i.e m1 = m2 = 3/8.
Putting value of slope (m1) in equation (i).
[tex](y - 8) = \frac{3}{8} (x + 4)[/tex]
Simplify them to get equation.
[tex]8(y - 8 ) = 3x + 12[/tex]
[tex]8y - 64 = 3x + 12[/tex]
[tex]3x - 8y + 12 + 64 = 0[/tex]
[tex]3x - 8y + 76 = 0[/tex]
Therefore therequired equation is 3x - 8y +76=0.
Hope it helps...
How do you divide decimals.
Answer:
we need to shift decimal then divide
Step-by-step explanation:
First we move the divisor (if its a decimal) to the right until there is no more dot. If your dividend is also a decimal you also need to move it to the right how many spaces you moved the divisor's.
Example:
923.56 ÷ 4.5
This means that we move the dot between 4 and 5 once. We do the same to 923.56.
This means our division problem will be
9235.6 ÷ 45.
Now just do the problem normally as you should.

You have a wooden rod which is 24 1/2 inches long. Carlos needs a piece which is 8 3/4 inches long and Amanda needs a piece which is 6 3/8 inches long. How long will the rod be after you cut those pieces to give to Carlos and Amanda?
Answer:
8 3/4 inches
Step-by-step explanation:
Total length of the rod = 24 1/2 inches
Carlos = 8 3/4 inches
Amanda = 6 3/8 inches
length of the rod remaining = Total length - ( Carlos + Amanda)
= 24 1/2 - (8 3/4 + 6 3/8)
= 49/2 - (35/4 + 51/8)
= 49/2 - ( 75+51/8)
= 49/2 - 126/8
= 196-126/8
= 70/8
= 8 6/8 inches
= 8 3/4 inches
Length of rod remaining = 8 3/4 inches
Answer:
9 3/8

what is a perfect square trinomial and can you provide an example
A perfect square trinomial is a trinomial that factors as two identical binomials.
For example, x² + 8x + 16 factors as (x + 4)(x + 4) or (x + 4)².
Another example would be x² - 12x - 36 which factors as (x - 6)².
