Part A; The vertical to horizontal ratio of the ramp in the question of 3:15 does not meet the ADA guideline of a vertical to horizontal ratio of 1:12
Part B; The measurement of the ramp that would meet ADA guideline is a vertical to horizontal ratio of 3 feet to 36 feet.
The front entrance of the ramp should therefore be 36 feet away
What is a ratio in mathematics?A ratio is an indication of the number of times one quantity is contained in another quantity.
The ADA guidelines requires that the rise angle ≤ 4.8°
The vertical ratio of the ramp ≤ 1:12
The distance the handicapped ramp must start = 15 feet from the front entrance
The rise of the ramp estimated by the contractors = 3 feet
Part A; The vertical to horizontal ratio of the ramp in the question = 3/15, which is 1:5
Therefore, the ramp does not meet ADA guidelines that requires a vertical to horizontal ratio of less than or equal to 1:12
Part B:
The ramp can be made to meet ADA guideline, whereby the horizontal distance from the entrance can be be adjusted as follows;
Let d represent the required horizontal distance of the front entrance, we get;
3:d = 1:12
From which we get;
[tex]\dfrac{3}{d} =\dfrac{1}{12}[/tex]
3 × 12 = 1 × d
d = 36
The horizontal distance of the front entrance of the ramp should be 36 feet away.

(a) Angle B = Angle C = 65 degree.
(b) Angle x and Angle y is 70 degree .
Given,
In the question:
9. Write a sequence of rigid motion to take figure ABC to figure DEF.
Now According to the question:
Take a figure ABC to figure DEF
So, CB = FE
BA = ED
Angle B = Angle E
10.(a) To find the unknown measure:
In triangle ABC
Angle A = 90 degree
To find the Angle B and C
Let the angle B and C be x
We know that :
Sum of angle triangle is 180 degree
50 + x + x = 180
50 + 2x = 180
2x = 180 - 50
2x = 130
x = 65°
Hence, Angle B = Angle C = 65 degree.
10. (b) Given,
Angle ABC = Angle BAC
If two sides of a triangle are congruent, then the angles opposite those sides are congruent.
Substitute Angle ABC = y and Angle BAC = x into Angle ABC = Angle BAC .
Angle (ABC + ACB + BAC) = 180 degree (Angle sum theorem)
=> y + 40 + x = 180
=> x + 40 + x = 180
=> 2x = 180 - 40
=> 2x = 140
x = 70°
Hence, Angle x and Angle y is 70 degree .

67 is a prime number and 1 is neither prime nor composite number.
What is prime number and composite number?
A prime number is a number which has exactly two factors i.e. '1' and the number itself. A composite number has more than two factors, which means apart from getting divided by 1 and the number itself, it can also be divided by at least one positive integer.
The given two numbers are 1 and 67.
Since, the prime numbers from 1 to 100 are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.
67 has exactly two factors i.e. 1 and the number 67 itself.
Therefore, 67 is a prime number.
Due to the fact that it only has one factor, 1, number is not a prime.

The probability of all four women being on the search committee as members in it is 1/273.
We have 15 people in total out of which there are 10 men and 5 women. We need four people on the committee out of these 15.
The probability of that happening can be calculated using the formula -
= Probability of all four women getting selected/Probability of all getting selected
= (5!/4!.1!) / (15!/4!11!)
= (5!/4!1!) * (4!11!/15!)
= (5*4*3*2*1) / (15*14*13*12)

Gabrielle is 15 years older than Milkhail. The sum of there ages is 95 what is Milhails age
The age of Milkhail is 40 years .
In the question ,
it is given that
the the sum of ages of Gabrielle and Milkhail is = 95
let the age of Milkhail be "m" .
given that Gabrielle is 15 years older than Milkhail
So, the age of Gabrielle is = m + 15
the equation representing the sum of ages is given by
total age = age of Milkhail + age of Gabrielle
95 = m + m + 15
adding the like terms ,
we get
95 = 2m + 15
subtracting 15 from both the sides
2m = 95 - 15
2m = 80
dividing both sides by 2
m = 80/2
m = 40

Another way to consider them is that in a proportionate relationship, one variable is consistently equal to the other's constant value. The "constant of proportionality" is the name of this constant.

The coordinates of the triangle S'T'U' is (2, -1), (5,3), (1, -4) and the triangle S"T"U" is (1,3), (4,5),(0,-2)
Coordinates:
Basically, the pair of numbers that describe the position of a point on a coordinate plane by using the horizontal and vertical distances from the two reference axes is known as coordinates.
Given,
The triangle STU is graphed at S(2,-1) T(5,-3) U(1,4). Triangle STU is reflected over the x-axis to create triangle S'T'U' and then translated by the rule (x,y) ->(x-1,y+2) to create S"T"U".
Here we need to find the coordinates for triangle S'T'U' and S"T"U".
In order to find the correct transformation for this triangle, we have to do the following,
The formula that is used to reflect a coordinate point about the x-axis.
(X2,Y2) = (X1,Y1) * (1,-1)
So, based on this rule, the coordinates of S'T'U' is,
S(2,-1) => S'((2 x 1), (-1 x -1)) = > S'(2,-1)
T(5,-3) => T'((5 x 1), (-3 x -1)) => T'(5, 3)
U(1,4) => U'((1 x 1), (4 x -1)) => U'(1, -4)
Now we have to apply the next rule,
=> (x, y) -> (x-1, y+2)
S'(2,1) => S'((2 - 1), (1 + 2)) = > S'(1, 3)
T'(5,3) => T'((5 - 1), (3 + 2)) => T'(4, 5)
U'(1,-4) => U'((1 - 1), (-4 + 2)) => U'(0, -2)
Therefore, the coordinates of S'T'U' is (2, -1), (5,3), (1, -4) and the coordinates of S"T"U" is (1,3), (4,5),(0,-2)

Answer:
563.7
Step-by-step explanation:
add 79 + 14.95 and multiply that by 6
suppose that there are two types of tickets: advanced and same day. advance tickets cost $25 and same day tickets are $30.for one performance there were 65 tickets sold in all. and the total amount paid for them was $1800.how many tickect of each were sold
The number of advance and same day tickets sold are 25 and 35 respectively.
How many tickect of each were sold?let
number of advance tickets sold = xNumber of same day tickets sold = yx + y = 65
25x + 30y = 1800
From (1)
x = 65 - y
Substitute x = 65 - y into (2)
25x + 30y = 1800
25(65 - y) + 30y = 1800
1625 - 25y + 30y = 1800
5y = 1800 - 1625
5y = 175
y = 175/5
y = 35
Substitute y = 35 into (1)
x + y = 65
x + 35 = 65
x = 65 - 35
x = 25
Therefore, Simultaneous equation is used to determine the number of advance and same day tickets sold.
25 advance tickets and 35 same day tickets were sold.
