A resort has 380 rooms with space for 6 people. Estimate the greatest number of people who could be in these rooms at the same time. Explain your thinking to a friend or family member.
Using the multiplication operation, the greatest number of people who could be in the 380 rooms with space for 6 persons at the same time is 2,280.
What is multiplication operation?Multiplication operation is one of the basic mathematical operations, including subtraction, addition, and division.
A multiplication operation involves applying the multiplier to the multiplicand to result in a product.
The total number of rooms in the resort = 380
The number of people per room = 6
380 x 6 = 2,280
Thus, by multiplication, if 6 persons occupy each of the 380 rooms, the resort will have 2,280 persons at a time.

Graph the line with slope 1 passing through the point (-2 , -5)
Graph the line.
The equation of the line is y = x -3. The graph of the line is attached below.
What is a line?
A line is an object in geometry that is indefinitely long and has neither breadth nor depth nor curvature. Since lines can exist in two, three, or higher dimensional environments, they are one-dimensional things. The term "line" can also be used to describe a line segment in daily life that contains two locations that serve as its ends.
Given that the slope of the line is 1.
Assume that the equation of the line is y = mx +c, where m is the slope of the line and c is y-intercepts.
Putting m = 1 in y = mx +c:
y = 1 × x +c
y = x +c
Since the line passes through the point (-2, -5), thus the point satisfies the given equation of line.
Putting x = -2 and y = -5 in y = x +c
-5 = -2 + c
c = -3
The equation of line is y = x - 3.
The points on the line are
(-2, -5), (0, -3), (3, 0).

If a cone has a volume of 100 cubic inches, what is the length of the radius? Round your answer to the nearest tenth.
The radius of the cone is 10√(3/πh) inches when the volume of the cone is 100 cubic inches.
According to the question,
We have the following information:
Volume of cone = 100 cubic inches
We know that the following formula is used to find the volume of cone:
Volume of cone = π[tex]r^{2}h/3[/tex] where r is the radius of the cone and h is the height of the cone
π[tex]r^{2}h/3[/tex] = 100
Now, using the cross multiplication method:
π[tex]r^{2}[/tex]h = 100*3
Dividing both sides of the equation by πh:
[tex]r^{2}[/tex] = 300/πh
r = 10√(3/πh) inches
We can also solve it further by putting the value of π.
Hence, the radius of the cone is 10√(3/πh) inches when the volume of the cone is 100 cubic inches.

The one time joining fee found from the linear relationship between total cost and the number of months of membership is $250
What is a linear relationship?A linear relationship is a relationship between two variables that has a straight line when graphed.
The total cost of the gym membership = C
The number of months of membership = t
The table in the question is presented as follows;
t (Time in months) [tex]{}[/tex] C (Total cost)
2 [tex]{}[/tex] 200
4 [tex]{}[/tex] 250
9 [tex]{}[/tex] 375
The linear equation that represents the value in the table is found as follows;
Slope of the line, m = (375 - 250)/(9 - 4) = 25
The equation of the line in point and slope form is therefore;
(C - 375) = 25·(t - 9)
C = 25·(t - 9) + 375
C = 25·t - 225 + 375 = 25·t + 250
C = 25·t + 250
The joining fee is the amount paid at the start when t = 0, therefore;
Joining fee = 25 × 0 + 250 = 250
The one time joining fee is $250

The sum of four positive integers is 125. If you increase the first number by 4, decrease the second by 4, multiply the third by 4, and divide the fourth by 4, you produce four equal numbers. What is the smallest of the original numbers
Step-by-step explanation:
a + b + c + d = 125
a + 4 = b - 4 = 4c = d/4
a + 8 = b
a = b - 8
16c = d
b = 4c + 4
4a + 16 = d
b - 8 + 4c + 4 + c + 16c = 125
4c + 4 - 8 + 4c + 4 + c + 16c = 125
25c = 125
c = 5
d = 16c = 80
4a + 16 = d = 80
4a = 64
a = 16
b = a + 8 = 16 + 8 = 24
so, the numbers are

why is not inverse function??
[tex]f(x) = x {}^{2} - 9[/tex]
The equation formed when x is the subject of the function f(x) = x² - 9, has two values of output for each input value to the function, therefore;
f(x) = x² - 9 does not have an inverse.
What is the inverse of a function?An inverse of a function is an anti function that reverses the values in the output into the input values thereby undoing the operations performed by the function.
A function f has an inverse if and only if it is bijective, such that there is a one to one correspondence between the set of the input elements and the set of the output elements
A function that has an inverse is said to be a bijective or invertible function or a function with one-to-one correspondence
The function in the question f(x) = x² - 9
Making x the subject of the function to verify if it has an inverse gives;
x² = f(x) + 9
[tex]x = \pm\sqrt{f(x) +9}[/tex]
Putting x = f⁻¹(x) gives;
[tex]f^{-1}(x) = \pm\sqrt{x +9}[/tex]
Therefore, each value of x gives two values of f⁻¹(x), such that the set of the output of inverse function, f⁻¹(x) does not have a one-to-one correspondence with the set of values of x.
The function f(x) = x² - 9 is not invertible and therefore does not have an inverse function.

The calculation of the ending inventory and the cost of goods sold using FIFO and LIFO methods for ABC Inc. is as follows:
FIFO LIFO
Ending inventory $10,250 $12,800
Cost of goods sold $17,000 $14,450
How does FIFO differ from LIFO?FIFO (First-in, First-out) assumes that the physical flow of goods sold depends on the chronological order of acquisition.
LIFO (Last-in, First-out) assumes that the cost of goods sold should be based on the latest inventory purchases.
Date Description Units Unit Costs Total Cost
April 1 Beginning inventory 220 $50 $11,000
April 5 Purchases 100 $60 6,000
April 10 Purchases 50 $45 2,250
April 16 Sales -300 $80
April 25 Sales -20 $95
April 30 Purchases 200 $40 8,000
Total 570 $27,250
Units sold 320
Ending inventory 250
FIFO:
Ending Inventory = $10,250 (200 x $40 + 50 x $45)
Cost of goods sold = $17,000 ($27,250 - $10,250)
LIFO:
Ending Inventory = $12,800 (220 x $50 + 30 x $60)
Cost of goods sold = $14,450 ($27,250 - $12,800)

True or False?
The ball was in the air for 1.5 seconds before hitting the ground.
The ball was in the air for 1.5 seconds. The answer is true.
What is a quadratic equation?The equation of the form ax² + bx +c is known as a quadratic equation.
The given equation is h(t) = -16t² + 20t + 6.
To find the time for which the ball was in the air, substitute h(t) =0.
0 = -16t² + 20t + 6
Use the quadratic formula to solve the equation:
[tex]t= \frac{- 20 \pm\sqrt{20^2 - 4(-16)(6)}}{2(-16)}\\t=\frac{- 20 \pm\sqrt{400+384}}{-32}\\t=\frac{- 20 \pm\sqrt{400+384}}{-32}\\t=\frac{- 20 \pm\sqrt{784}}{-32}\\\\t= \frac{- 20 \pm28}{-32}[/tex]
t = (-20 + 28)/(-32) or t = (-20-28)/(-32)

Similar to how a function's constituent terms can be added, subtracted, multiplied, and divided, so can functions. These are to be noted as follows:
Addition f( x ) + g ( x ) means to combine two functions, and it may alternatively be expressed as ( f + g ) ( x )
It is possible to write ( f g ) ( x ) to represent the operation of subtracting the g(x) function from the f(x) function.
The two functions are multiplied together when you multiply f (x ) g (x), which can also be represented as (f g ) (x).
Division f (x)/g (x) means to split the two functions in half, and it can alternatively be expressed as (f/g)(x).
Here the given function ,
