(ii) Calculate the total time, in hours and minutes, that the wildlife park is open in one ye
Based on the information given in the table, the opening hours on Wednesday and throughout the year is 7 hours , 45 minutes and 845 hours respectively.
Opening times ::
Monday to Friday : 09:30 - 17:15 Saturday and Sunday : 10:00 - 18:30Opening duration on Wednesdays :
Closing time - Opening time on weekdays :
17:15 - 09:30 = 7 hours, 45 minutes
Opening duration in a while year :
Opening duration on weekdays per week = 7 hours 45 minutes
Opening duration on weekends per week = 8 hours 30 minutes
Total opening duration per Week :
(weekday + weekend)(7 hours 45 minutes + 8 hours 30 minutes) = 16 hours 15 minutes
Number of weeks per year = 52
Total opening time per year :
(16 hours 15 Minutes) × 52 = 845 hoursTherefore, the park opens for a total of 845 hours per year.

How do you determine the domain of a function ?
Answer:
Let y = f(x) be a function with an independent variable x and a dependent variable y.
If a function f provides a way to successfully produce a single value y using for that purpose a value for x then that
chosen x-value is said to belong to the domain of f. If there is a requirement that a y-value produced by a function
must be a real number, the following conditions are commonly checked:
1. Denominators cannot equal 0.
2. Radicands (expressions under a radical symbol) of even roots (square roots, etc)
cannot have a negative value.
3. Logarithms can only be taken of positive values.
4. In word problems physical or other real-life restrictions might be imposed, e.g. time is
nonnegative, number of items is a nonnegative integer, etc.
Answer:
the domain is a set of all possible numbers inputs for that function, THe range is all the possible output numbers

How would the domain and range of the function
Y = (1/4)x - 6
be determined? Explain.
Answer:
Domain and range both [tex](-\infty, \infty)[/tex]
Step-by-step explanation:
The range is determined by finding the domain of the inverse of the function(if it has one, in this case it does). The domain is easily determined, because [tex]x[/tex] can obviously range from [tex](-\infty, \infty)[/tex] without restriction.
The inverse of the function can be found as such:
[tex]x=(1/4)f^{-1}(x)-6\\x+6=(1/4)f^{-1}(x)\\4(x+6)=f^{-1}(x)\\f^{-1}(x)=4x+24[/tex].
Here, [tex]x[/tex] can also range from [tex](-\infty, \infty)[/tex] without restriction.
So, the domain and range are both [tex]\boxed{(-\infty, \infty)}[/tex]

The base of a 14-foot ladder is 5 feet from a building, If the ladder reaches the flat roof, how tall is the building?
The height of the wall of the building is 13.067 feet.
What is the Pythagorean theorem?Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
Given that the base of a 14-foot ladder is 5 feet from a building. The height of the building will be calculated as below:-
Applying the Pythagorean theorem to calculate the height of the building.
H² = P² + B²
14² = P² + 5²
P² = 14² - 5²
P = √171 = 13.07 feet
Therefore, the height of the wall of the building is 13.067 feet.

Find the measures of angle 1 and angle 2. State the theorem or postulate that justifies your answer,
Answer:
Angle 2 = 55
Angle 1 = 125
Step-by-step explanation:
Considering the line vertical lines are parallel:
Angle 2 and angle with measure of 125 are supplementary and their sum is = 180
So m<2 = 180 - 125 = 55
For angle 1:
Again since the vertical lines are parallel:
Angle 1 and angle with given measure 125 are alternate and has same measurement.
Answer:
Angle 2= 55 degrees
angle 1= 125 degrees
Step-by-step explanation:
Angle 2 uses SA, 180-125=55
angle 1 is parallel to the 125 degree line

2a + 2 = 3 (a + 2)
Answer:
The equation has “one solution” because a = -4
Step-by-step explanation:
2a + 2 = 3 (a + 2)
2a + 2 = 3a + 6
-2 -2

2a = 3a + 4
-3a -3a

Properties used:
All angles of a triangle add up to 180 degrees
180 is a straight line; so both sides of a straight line add up to 180
10) 180 - 153 = 27
180-27-133 = ?
? = 20 degrees
11) 180-87=93
180-93-23=?
? = 64 degrees
Answer:
11.) Angle FED = 20 Degrees | 12.) Angle FHG=74
Step-by-step explanation:
11.) Angle FED= 20 degrees
one side of a straight line = 180 degrees
all the angles of the insides of a triangle added together = 180 degrees
If angle EDF is 153 degrees, we do 180 - 153 = 27 degrees. Now we know that angle FDE = 27 degrees. Now we add all the angles we have together. 133+?+27=180. (133+27=160) If 160+?=180, we solve it by doing: 180-160, and we get 20.
12.) Angle FHG=74
For this problem, we use the same formulas as before. So let's solve!
180-87=93. So angle GFH=83 degrees.
Now we need to add the angles together:
83+23+?=180. 83+23=106
180-106=74.

What is 19% of 41?
(Simplify, no links)
Answer:
7.79
Step-by-step explanation:
19 percent of 41 is the same as 19 per hundred of 41. We can therefore make the following equation:
19/100 = X/41
To solve the equation above for X, you first switch the sides to get the X on the left side, then multiply each side by 41, and then finally divide the numerator by the denominator on the right side to get the answer. Here is the work to illustrate:
19/100 = X/41
X/41 = 19/100
X*41/41 = 19*41/100
X = 779/100
X = 7.79
The work above shows the long way to explain how to calculate 19 percent of 41 in order to give you a foundation and better understanding of how to calculate the percentage. In the future, you could use this simplified formula:
(Y * P)/100
In our problem "What is 19 percent of 41?", Y is 41 and P is 19:
(41 * 19)/100 = 7.79
And once again you see that the answer is 7.79.

4. Identify the graph of the solution set of 9 > 3 + 2x.
Answer:
A
Step-by-step explanation:
9 > 3 + 2x
6 > 2x
3 > x
or
x < 3
and that means 3 is NOT included (otherwise there must be a smaller or equal sign). hence A is the right answer.
The graph of the solution set [tex]9 > 3 + 2x[/tex] is represented by the inequality relation x < 3.
The correct answer is Option A.
Given data:
The inequality is represented as 9 > 3 + 2x
The solution set of the inequality 9 > 3 + 2x can be found by isolating x on one side of the inequality:
Subtract 3 from both sides: 9 - 3 > 2x
Simplify: 6 > 2x
Divide both sides by 2: 3 > x
So, the solution set is x < 3.
Graphically, this represents all the values of x that are to the left of (less than) 3 on the number line. It forms an open interval to the left of 3. The graph consists of all real numbers less than 3, not including 3 itself. In interval notation, this can be written as (-∞, 3).
Hence, the inequality is x < 3.
