The combined average weight of an okapi and a llama is 450450450 kilograms. The average weight of 333 llamas is 190190190 kilograms more than the average weight of one okapi. On average, how much does an okapi weigh, and how much does a llama weigh?
Llama's weight will be 160kg and Okami's weight will be 290kg.
What is an average?An average is one number chosen to represent a group of numbers; it is often the sum of the numbers divided by the number of numbers in the group.
The weight for both will be calculated as below:-
x= Okapi weight
y= Llama weight
There are 2 equations to be written:
1) 450kg is equal to the weight of one Okapi and one Llama.
450kg= x + y
2) The weight of 3 llamas is equal to the weight of one Okapi plus 190kg.
3y=190kg + x
Solve for one variable in one equation and substitute the answer in the other equation.
450kg= x + y
Subtract y from both sides.
450-y =x
Substitute (450-y) in the second equation in place of x to solve for y.
3y=190kg + x
3y=190 + (450-y)
3y=640 -y
Add y to both sides.
4y=640
Divide both sides by 4.
y=160kg Llama weight
Substitute 160kg in either equation to solve for x.
3y=190kg + x
3(160)=190 + x
480=190 + x
Subtract both sides by 190.
290= x
x= 290kg Okapi weight
Therefore, Llama's weight will be 160kg and Okami's weight will be 290kg.

The roof of a factory rises vertically 7 ft through a horizontal run of 42 ft. What is the pitch of the roof?
Final answer:
The pitch of the roof, which rises vertically 7 ft through a horizontal run of 42 ft, is 2. This means the roof rises 2 inches for every 12 inches of horizontal run.
Explanation:
The question asks about calculating the pitch of a roof with a vertical rise of 7 ft and a horizontal run of 42 ft. The pitch of a roof is generally expressed as the amount of vertical rise per 12 inches of horizontal run. To find the pitch, we first need to calculate the rise per 12 inches of horizontal run.
Given:
Rise = 7 ft
Run = 42 ft
To find how much the roof rises for every 12 inches of run, we use the formula:
Pitch = (Rise / Run) × 12
Plugging in the given values:
Pitch = (7 / 42) × 12 = 2
Thus, the pitch of the roof is 2, meaning the roof rises 2 inches for every foot (12 inches) of horizontal run.

A florist sold 15 arrangements in its first month of business. The number of arrangements sold doubled each month.
What was the total number of arrangements the florist sold during the first 9 months?
Answer:
total number of arrangements the florist sold during the first 9 months = 7665 arragements
Explanation:
Florist start a business.
In his 1st month Florist sold 15 arrangement.
He grow his business, he sold twice arrangements as compare to the previous month.
First month = 15
Second month = 2*15 = 30
Third month = 2*30 = 60
15, 30, 60 .....
we need to find the total number of arrangements in first nine months
This sequence is geometric series.
A geometric sequence is a sequence such that any element after the first is obtained by multiplying the preceding element by a constant called the common ratio which is denoted by r. The common ratio (r) is obtained by dividing any term by the preceding term, i.e.,
r = [tex] \frac{30}{15} = \frac{60}{30} = 2 [/tex]
Sum of Terms in a Geometric Progression ([tex] S_{n} [/tex])= [tex] \frac{a_{1} (r^{n} -1)}{r-1} [/tex]
where [tex] a_{1} [/tex] is first term = 15
n is the number of terms = 9
r is common ratio = 2
[tex] S_{9} =\frac{15(2^{9}-1)}{2-1} [/tex]
[tex] S_{9} =\frac{15*(512-1)}{1} [/tex]
[tex] S_{9} = 7665 [/tex]
total number of arrangements the florist sold during the first 9 months = 7665.

Tickets to a school play cost $3 for students and $8 for adults. On opening night, $1000 was collected and 150 tickets sold. How many of each kind of ticket were sold? Write a system of equations and use substitution to solve.
To solve this problem, set up a system of equations representing the number of student and adult tickets sold. Solve the system using substitution to find the numbers of each type of ticket sold.
Explanation:To solve this problem, we can set up a system of equations to represent the number of student tickets and adult tickets sold.
Let x be the number of student tickets sold and y be the number of adult tickets sold.
We know that the total number of tickets sold is 150, so we have the equation:
x + y = 150
We also know that the total amount collected is $1000, so we have the equation:
3x + 8y = 1000
We can solve this system of equations using substitution.
From the first equation, we can solve for x in terms of y as:
x = 150 - y
Substituting this into the second equation, we have:
3(150 - y) + 8y = 1000
Simplifying, we get:
450 - 3y + 8y = 1000
Combining like terms, we get:
5y = 550
Dividing both sides by 5, we get:
y = 110
Substituting this value back into the first equation, we have:
x + 110 = 150
Simplifying, we get:
x = 40
Therefore, 40 student tickets and 110 adult tickets were sold.

A rectangular auditorium seats 1344 people. The number of seats in each rows exceeds the number of rows by 20. Find the number of seats in each row
To solve this problem, we must first set up an equation. We are told that the total number of seats in the auditorium is 1344. We are also told that the number of seats in each row exceeds the number of rows by 20.
Let's denote the number of rows as x. Therefore, the number of seats per row is x + 20 (as it exceeds the number of rows by 20). Setting up an equation would be as follows:
x * (x + 20) = 1344
This equation states that the number of rows times the number of seats per row equals the total number of seats.
Solving this equation requires finding the roots of a quadratic equation. We set it up as a quadratic equation ax² + bx + c = 0. Here, a = 1, b = 20, and c = -1344.
Solving a quadratic equation gives us two possible solutions, but in our case, we disregard the negative value, as the number of rows cannot be negative. So, we take the maximum of the two roots.
Solving this equation gives us x = 28.0, which represents the number of rows.
Finally, to find the number of seats in each row, we remember that it exceeds the number of rows by 20. So, we add 20 to the number of rows.
28.0 + 20 = 48.0
So, there are 48 seats in each row.

A pilot flies 720 miles from dallas, texas, to his first destination. after dropping off his cargo, he flies southeast 290 miles to his second destination. if the angle formed by his trip is 125°, what is the distance he will fly from the second destination back to dallas? 490 miles 918 miles 1,010 miles 842,026 miles
Answer:
B) 918 miles
Step-by-step explanation:
Here with I have attached the figure of the story.
Here we need to find side c, which represents distance from the second destination back to Dallas.
We have to use the cosine formula to find the missing side.
If we are given two sides and one included angle, we can use the cosine formula and find the missing side.
a = 720, b = 290 and ∠C =125°
[tex]c^2 = a^2 + b^2 - 2ab cos C[/tex]
Now plug in the given values and simplify.
[tex]c^2 = {720}^2 + 290^2 - 2*720*290 cos 125[/tex]
[tex]c^2 = 518400 + 84100 - 417600 cos125[/tex]
[tex]c^2 = 602500 - (-239,525.5)\\c^2 = 602500 + 239,525.5\\c^2 = 842025.5[/tex]
Taking the square root on both sides, we get
c = 917.6
Which is equivalent to 918 miles (rounded off to the nearest whole number)

Answer:
The value of x in the given figure is, [tex]34^{\circ}[/tex]
Step-by-step explanation:
Complementary angle states that the two angles sum up to 90 degree.
From the given figure
[tex]x^{\circ}[/tex] and [tex]56^{\circ}[/tex] are complementary angles.
by definition of complementary angles;
[tex]x^{\circ} +56^{\circ} = 90^{\circ}[/tex]
Subtract [tex]56^{\circ}[/tex] from both sides we get;
[tex]x^{\circ} = 90^{\circ} -56^{\circ}[/tex]
Simplify:
[tex]x = 34^{\circ}[/tex]
therefore, the value of x in the given figure is, [tex]34^{\circ}[/tex]
