Answer: 125 pounds
Step-by-step explanation:
Let's first represent the weight of the black rhinoceros and chimpanzee with variables. We will assign r for the rhinoceros and c for the chimpanzee.
In the question, we were given that the weight for a black rhinoceros is 18 times as much as an average-size chimpanzee. This makes 18 times the chimpanzee's weight equal to the rhinoceros' weight.
Let's put this into an equation.
[tex]r=18*c[/tex]
Now, let's put in the values we know to find the weight of the chimpanzee (i.e., c). We know the weight of a rhinoceros (represented by r) is 2250 pounds, so we can replace it for r in the equation.
[tex]2250=18*c[/tex]
To solve this equation, we can divide both sides by 18 to get c by itself and know what it's value is.
[tex]\frac{2250}{18}=\frac{18*c}{18}[/tex]
We can remove the [tex]\frac{18}{18}[/tex] from the right side to be left with c. We can also divide 2250 by 8 to get the weight of an average-size chimpanzee.
[tex]c=\frac{2250}{18}\\ c=125[/tex]
Hence, an average-size chimpanzee weighs 125 pounds.

For upcoming trip. Tim should hire company A
What is linear equation?A linear equation is an algebraic equation where each term has an exponent of 1 and when this equation is graphed, it always results in a straight line. This is the reason why it is named as a 'linear equation'.
Given,
Distance to cover = 250 miles
For company A
By the graph line passes through
(200, 200) , (0,150)
equation of the line,
y-150 = [(200-150)/(200-0)](x-0)
y-150 = [50/200] x
y = x/4 + 150
y = 0.25 x + 150
No. of miles = 250
y = 0.25×250 + 150
y = 62.5 + 150
y = $212.5
Price for company B
y' = 0.75x + 50
where x is number of miles
for 250 miles price of company B
y' = 0.75 × 250 + 50
y' = 187.5 + 50
y' = $237.5
∵ y < y'
∴Price of trip with company A is less than company B
Hence, Tim should hire Company A for upcoming trip.

The heights of American men aged 18 to 24 are approximately Normally distributed with a mean of 68 inches and a standard deviation of 2.5 inches. About what percentage of the men are over 70.5 inches tall?
a ----2.5
b-----68
c-----16
d----5
e-----32
Answer:
Step-by-step explanation:
To find the percentage of men who are over 70.5 inches tall, we need to use the standard normal distribution table, which gives the proportion of observations that fall within a given range of standard deviation from the mean.
We first need to standardize the height of 70.5 inches by subtracting the mean (68 inches) and dividing by the standard deviation (2.5 inches) to get (70.5 - 68) / 2.5 = 0.8
This tells us that 70.5 inches is 0.8 standard deviations above the mean.
We can then look up the proportion of observations that fall within this range in the standard normal distribution table, which is approximately 0.1587 or 15.87%. So, the answer is (1-0.1587) = 84.13 or 84.13%.
So the answer is 84.13%
(URGENT) lWhich pair of functions are inverses of each other?
If the two graphs are mirror images of one another across the line y = x, then they are inverse functions.[tex]$f(x)=\frac{x}{3}+10$ \\[/tex] and [tex]$g(x)=3 x-10$[/tex]
How do you find a pair of inverse functions?As for looking at the graphs, we already knew that. You should keep in mind that inverse functions are represented by two graphs that are mirror images of one another over the line y = x. The broadest definition of an inverse function is one that "reverses" another function.
The inverse, for instance, must take b to an if a function goes from a to b. When the first and second elements of each pair in the original function are switched, a set of ordered pairs is obtained that is known as the inverse of the function. The act of switching the x and y coordinates is known as obtaining an inverse. They aren't opposites. The output of the first function is sent through an inverse function, which then generates an output whose input was the first function.
So, option A) [tex]$f(x)=\frac{x}{3}+10$ \\[/tex] and [tex]$g(x)=3 x-10$[/tex] is the appropriate response.

Find the exact circumference of each circle
By dividing the circle's diameter by, you may determine a circle's circumference (pi). By dividing 2radius by pi, or 3.14, you may also determine the circumference.
What is Circle’s Circumference?The diameter of a circle, also known as its circumference or perimeter, is the measurement of the circle's edge. As opposed to this, a circle's area indicates the space it occupies. The circumference of a circle is its length when we cut it open and draw a straight line from it. Units like centimeters or meters are typically used to measure it.The circle's radius is taken into consideration when applying the formula to determine the circumference of the circle. Therefore, in order to calculate the circumference of a circle, we must know its radius or diameter.The perimeter (or circumference) of a circle is equal to two R.where,R denotes the circle's radius.
The mathematical constant has a value that is around 3.14 (to the nearest two decimal places).Again,
As the ratio of any circle's circumference to diameter, pi () is a unique mathematical constant.and C = D
C represents a circle's circumference.D represents the circle's diameter.Calculate the circle's circumference, for instance, if its radius is 4 cm.Radius is given as 4 cm.Circumference = 2r

Very confused, if you could please explain it to me, that would be great!!
The sum of the exterior angles for a parallelogram is 360°.
What is exterior angle?Exterior angles are angles that are formed outside two lines when they intersect. They are located outside the two lines, on the outside of the shape. They can be found by adding the two interior angles together, whose measurements are always equal to 180 degrees. Exterior angles are also supplementary angles, meaning that the sum of their measurements is always equal to 360 degrees.
This is because the four angles on the outside of the parallelogram are all right angles, and the sum of four right angles is 360°.
Similarly, the sum of the exterior angles for a hexagon is also 360°.
This is because the six angles on the outside of the hexagon are all 120° angles, and the sum of six 120° angles is 360°.

Step-by-step explanation: To solve f(x), g(x), or f(g(x)) problems, we place the value of x in the functions with the value that we are given. This value will be f(g(5)) or g(3) or f(27). We plug in the number in the parentheses.
In this problem, we have to first plugin 5 to g(x) then plug g(5) into f(x).
First, we do g(5)=sqrt((5^2)+2). This gives us 3. Then we plug in 3 which is g(5) into f(x). This gives us f(g(5)) or f(3)=sqrt((3^3)-2) which is 5.
