The americans with disabilities act sets a maximium angle for a wheelchair ramp entering a business at 4.76 degrees. Determine the horizontal distance needed to occomidate a ramp that goes up to a door.
Answer:
d = 48.03 feet
Step-by-step explanation:
Given that,
The maximum angle for a wheelchair ramp entering a business at 4.76 degrees.
We need to find the horizontal distance needed to accomidate a ramp that goes up to a door 4 feet of the ground.
We can solve it using trigonometry.
[tex]\tan\theta=\dfrac{h}{d}[/tex]
Where
h is height
d is the angle of elevation
[tex]d=\dfrac{h}{\tan\theta}\\\\d=\dfrac{4}{\tan(4.76)}\\\\d=48.03\ ft[/tex]
So, the horizontal distance is equal to 48.03 feet.

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
Let the temperatures on different days be represented by the table
Now , total temperature is S = -6 + 3 + 4 - 2 - 1

The surface area of a cone is determined by the equation SA= a rs + a r2, where r is the radius and s is the slant
height. The functions f(x) and g(x) both model the surface area of a cone. One of the functions represents the
surface area of a cone with a radius of 5 and a slant height of x. The other function represents the surface area of a
cone with a slant height of 5 and a radius of x. Which statement correctly matches the description of the function
with the domain of the function in the context of the problem situation?
The function f(x) models the surface area of a cone with a radius of 5, a slant height of x, and has a domain in
the context situation of x < 5.
® The function f(x) models the surface area of a cone with a radius of 5, a slant height of x, and has a domain in
the context situation of x > 5.
© The function g(x) models the surface area of a cone with a radius of 5, a slant height of x, and has a domain in

Which expression below has a coefficient, a product, and a sum? A. (3 / 3) + (6 – 2) B. (3/n) + (6 + 2) C. 3n(6) + (6 – 2) D. n + (6 – 2)
Answer:
C. 3n(6) + (6 – 2)
Step-by-step explanation:
C. 3n(6) + (6 – 2) has a coefficients, a product and a sum
Coefficients = 3
3 is the coefficients of n
Product means multiplication
3n(6) = product of 3n and 6
Sum means addition(+)
3n(6) + (6 – 2) = the addition of 3n(6) and (6 - 2)
3n(6) + (6 – 2)
= 18n + (4)
= 18n + 4

What is diameter:
in geometry, a diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle. Both definitions are also valid for the diameter of a sphere.
What is radius:
In classical geometry, a radius of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length. The name comes from the Latin radius, meaning ray but also the spoke of a chariot wheel.
Explanation:
The diameter is the line that goes across the center of the circle and double the radius which is half, therefore KR is the correct answer.
Answer:
KR, D, or the last option.
Statement answer:
Segment KR is the Diameter of Q.

Find the length of each arc. Use the exact answer
Answer:
D) 16π/3 ft
Step-by-step explanation:
We solve the above question using the Arc length formula when our central angle is in degrees
The formula is given as:
Arc length = 2πr × θ /360
r = 4 ft
θ = Central angle in degrees = 240°
Hence,
2 × π × 4 × 240/360
8π × 240/360
8π × 20/30
16π/3 ft
Arc length = 16π/3 ft
Option D is the correct option

Line segments MP and ML are perpendicular chords in circle O. MP = 10 and ML = 24. Triangle L M P is inscribed within circle O. The length of M P is 10 and the length of M L is 24. Angle P M L is a right angle. Which statements about circle O are true? Select three options. The radius of circle O is 13. The diameter of circle O is 34. LP is a diameter of circle O. ∠LMP intercepts a semicircle. The measure of arc LP is 90°.
Answer:
The radius of circle O is 13.
∠LMP intercepts a semicircle.
LP is a diameter of circle O
Step-by-step explanation:
Find the diagram attached
From the circle, PL is the diameter of the circle;
Also, LMP intercepts a semicircle since the triangle LMP is a triangle in the semicircle of the circle.
According to pythagoras theorem;
ML²+MP² = PL²
24²+10² = PL²
576 + 100 = PL²
676 = PL²
Swap
PL² = 676
PL = √676
PL = 26
Since radius = diameter/2
Radius of the circle = 26/2
Radius of the circle = 13
Hence the radius of circle O is 13.

How many dimes and quarters?
what would the system look like?
picture is linked!!!
Answer:
I think it is twenty-three dimes and one quarter
Answer:
7 quarters and 8 dimes
Step-by-step explanation:
If you count up the amount of money that 7 quarters is, then they are equal to $1.75. Next you would add 10 to that amount until you got to $2.55, and you would end up with 8 dimes. And 8 + 7 = 15.
