Answer:
I think that the ADA (Americans with Disabilities Act) has explicit regulations on slopes and ramps so that people with disabilities can go about their daily life easier, and to guarantee the safety and wellbeing of the disabled. If, for instance, a wheelchair ramp were too steep, there would be a danger of the wheelchair rolling down too quickly, or the person falling backward on their way up.
Set it up as a ratio: 1/m = 2/m+7 and cross-multiply to get m+7 = 2m. Now solve
Answer:
47% of the students who chose pepperoni pizza as their favorite
Answer (D)
Step-by-step explanation:
∵ The total number of the students in grade 7 is
171 + 254 = 425 students
∵ The total number of the students in grade 8 is
285 + 143 = 428 students
∴ The total number of students in both grades is
425 + 428 = 853 students
∵ The number of students in grade 7 who like pepperoni pizza
as their favorite is 254
∵ The number of students in grade 8 who like pepperoni pizza
as their favorite is 143
∴ The number of students who like pepperoni pizza as their
favorite in both grades = 254 + 143 = 397 students
∴ % of student who chose pepperoni pizza as their favorite is
(397/853) × 100 = 46.5% ≅ 47%
∴ The answer is (D)
Answer:
y = - 3x + 9 or (y - 6) = - 3(x - 1)
Step-by-step explanation:
I'm assuming you are looking for the equation of the line.
First, let's find the slope of the line, which we use equation (y1-y2) / (x1-x2)
x1: 1 x2: 2
y1: 6 y2: 3
(6-3) / (1-2) = 3 / -1 = -3
The slope of the line is -3.
The equation for slope-intercept form is y = mx + b, where m is slope and b is the y - intercept.
y = -3x+b
Now substitute a set of points in (any coordinates work). I'll use (1, 6)
6 = -3(1)+b
6 = - 3 + b
b = 9
So our equation in slope intercept form is y = - 3x + 9
You can also write this in point slope form, (y-y1) = m (x-x1) m is still slope
(y - 6) = - 3(x - 1)
