The horizontal part of a step is called the tread. the vertical part is called the riser. the recommended riser-to-tread ratio is 7 inches : 11 inches. a. find the value of x for stairs built using the recommended riser-to-tread ratio. round your answer to the nearest tenth.
The value of x for these stairs built by using the recommended riser-to-tread ratio is 32.5°.
Given the following data:
Length of riser = 7 inches.Length of tread = 11 inches.Ratio = 7:11.How to determine the value of x.In Mathematics, a tread refers to the horizontal part of a step while a riser is the vertical part of a step.
Note: Let the angle of inclination be x.
In Geometry, two (2) lines that are parallel have the same alternate interior angles. Thus, the angle of inclination between the riser and tread is given by:
[tex]Tan x = \frac{rise}{tread} \\\\Tan x = \frac{7}{11} \\\\Tan x = 0.6364\\\\x=tan^{-1}0.6364[/tex]
x = 32.5°.

A driver of a 1 000 kg jeepney travelling at a speed of 16,7 m/s bound for divisoria applies the car's brakes when he sees a red light along recto avenue. the car's brakes provide a frictional force of 8 000 n. determine the stopping distance of the car.
The stopping Distance of the Car with the given parameters is; 17.43 m
What is the stopping sight distance?
We are given;
mass; m = 1 000 kg
speed; u = 16.7 m/s
Frictional force; F = 8000 N
distance, s = ?
final velocity = 0 m/s (car stops)
Formula for final velocity is;
v² = u² + 2as
but a = negative (deceleration)
And F = ma
Thus;
a = F/m = 8000/1000
a = 8 m/s²
Thus;
0 = (16.7)² - 2(8)(s)
278.89 = 16s
s = 17.43 m

which of the following most accurately explains an impact of burmese pythons on the everglades community in southern florida using the data provided?
An impact of Burmese pythons on the everglades community in Florida is that python predation has caused a trophic cascade that changed the mosquitoes' niche.
The impact of Burmese pythons.As a result of the predation by invasive Burmese pythons in the United States of America, the number of raccoons and white-tailed deer has decreased significantly in southern Florida.
Consequently, the mosquitoes' niche has been changed by a trophic cascade because they were forced to find alternative hosts such as cotton rats.

Twelve identical point charges q are equally spaced around the circumference of a circle of radius r. the circle is centered at the origin. one of the twelve charges, which happens to be on the positive x axis, is now moved to the center of the circle.
There is only one net force acting on the charge at the center of the circle that will only be subjected to a repulsive force from the charge is extant on the negative axis of x.
What is a line charge?A line charge refers to the charge that is allocated along a curve that is one dimensional in nature such as a circle.
In physics experiments, line charges are used in wire chambers. Wire chambers are used for high-energy physics experiments.
In summary, the charges are put at equal distances around the circumference of the circle in the example.
Because the charges at the opposing ends of the circle are similar, they exert an equal-magnitude repelling force in the opposite direction on the charge at the center of the circle, thus balancing out the forces.
This is why there is only one net force acting on the charge at the center of the circle that will only be subjected to a repulsive force from the charge is extant on the negative axis of x.
