The answer is 60%
According to the original information given, the estimated average number of shoppers in the original store at any time(x) is 45.
In the question, it states that, in the new store, the manager estimates that an average of 90 shoppers per hour(60 minutes) enter the store, which is equivalent to 1.5 shoppers per minute(s).
The manager also estimates that each shoppers stays in the store for an average of 12 minute (t). Thus, by Little's law there are, on average,
x = s x t
=> x = 1.5 x 12
=> x = 18
Hence, there are 18 shoppers at any time in the new store.
Now, Percentage of shoppers
[tex]\frac{45-18}{45}[/tex] x 100 = 27/45 x 100 = 2700/45 = 60%

The circumference is 25 ft I have to find what X is for my radius
R= -4x-5
The value of x based on the information given about the circumference is 2.24.
How to illustrate the information?It should be noted that the circumference is calculated as:
= 2πr
where
π = 3.142
r = radius = 4x - 5.
Circumference = 25
Therefore, circumference = 2πr.
(2 × 3.142)(4x - 5) = 25
6.284(4x - 5) = 25.
25.136x - 31.42 = 25
Collect like terms
25.136x = 25 + 31.42
25.136x = 56.42
x = 56.42 / 25.136
x = 2.24
Therefore, the value of x based on the information given about the circumference is 2.24.

the shorter leg of a right triangle is 8 less than the hypotenuse. the longer leg is one less than the hypotenuse. find the perimeter
The perimeter of the right triangle is 30 units.
How to find the perimeter of a right triangle?The shorter leg of the right triangle is 8 less than the hypotenuse. The longer leg is one less than the hypotenuse.
Let's break the information into smaller chunk.
The shorter leg of a right triangle is 8 less than the hypotenuse.
The longer leg is one less than the hypotenuse.
The hypotenuse is the longest side of a right triangle.
Therefore,
let
the hypotenuse = x
short leg = x - 8
long leg = x - 1
Applying Pythagorean theorem in the given right triangle.
c² = a² + b²
where
c = hypotenusea and b are the other legs.(x - 1)² + (x - 8)² = x²
(x - 1)(x - 1) + (x - 8)(x - 8) = x²
x² - x - x + 1 + x² - 8x - 8x + 64 = x²
2x² - 18x + 65 = x²
x² - 18x + 65 = 0
(x - 13)(x - 5) = 0
Therefore,
x = 5 and x = 13
13² - 5² = a²
169 - 25 = a²
a = √144
a = 12
So, the hypotenuse is 13, the shorter leg is 5 and the longer leg is 12.

ar travels on a straight, level road. (a) Starting from rest, the car is going 38 ft/s (26 mi/h) at the end of 4.5 s. What is the car's average acceleration in ft/s²?
The car's average acceleration is 8.44 ft/s².
Acceleration is defined as the rate of change of velocity per unit time. It is usually denoted by the letter a.
Here, we are given that a car travels on a straight road. Starting from rest, the car is going at 38 ft/s (26 mi/h) at the end of 4.5 s.
Acceleration of an object can be calculated using the given formula-
acceleration = velocity/ time
Here, the velocity of the car will be 38 ft/s
and the time is equal to 4.5 seconds.
Thus, putting these formulas in the equation, we get-
acceleration of the car = 38/ 4.5
= 380/ 45
= 8.44
Thus, the car's average acceleration is 8.44 ft/s².

Answer:
Blank 1: 97
Blank 2: 73
Step-by-step explanation:
This equation is shown on a straight line, which equals 180.
We can start by adding the two equations which together are equal to 180.
15x + 2 + 10x + 3 = 180
We can simplify it to 25x + 5 = 180
Now we can subtract 5 from both sides to get
25x = 175
Then we can divide both sides by 25 to get x = 7
Now we can plug in x for both angles
Angle RQS is 15x + 2, so 15*7=95 and the +2 is 97.
Angle TQS is 10x + 3 so 10*7=79 and the + 3 is 73

A print shop borrows $5700 from a credit union for 193 days. The credit union charges simple interest at an annual rate of 12% for this loan. Assume 1/365 each day is
of a year. Answer each part below.
Do not round any intermediate computations, and round your final answers to the nearest cent. If necessary, refer to the list of financial formulas.
The amount borrowed by the print shop: $5700
Time for which loan is taken: 193 days
Rate of interest: 12%
Day in terms of year is given by: 1/365
The formula for simple interest:
Simple interest = P*R*T/100
where P = principal amount invested
R = rate of interest
T = time in years
Solving the question using the formula we have:
Simple interest = (5700*12*193)/(100*365)
= 13201200/36500
= 361.67 or $362
Interest that will be owed after 193 days will be $362
Amount owed after 193 days will be $5700 + $362 = $6062

Abdul wants to put a rug in a square room that has an area of 775 square feet. He wants to leave a 3-foot border of bare floor on each side. What are the dimensions of the rug rounded to the nearest hundredth?
The dimensions of the rug which Abdul would use in discuss as described in the task content are; 21.84 ft by 21.84 ft.
What are the dimensions of the rug rounded to the nearest hundredth?It follows from the task content that the dimensions of the rug which Abdul would use in the room in discuss are to be determined.
Since the room Abdul wants to put a rug on is; 775 ft² and the room is a square room.
It follows that all sides of the room are equal and the length of each side can be determined as;
s = √Area; since Area = s².
s = √775
s = 27.839 ft.
Hence, the dimensions of the room is; 27.839 ft by 27.839 ft.
However, since he wants to leave a 3-foot border of bare floor on each side, it follows that the dimensions of the rug on each axis would be;
= 27.839 - 3 -3 = 21.839 ft on all sides.
Consequently, the dimensions of the rug rounded to the nearest hundredth are; 21.84 ft by 21.84 ft.

A pool measuring 18 meters by 20 meters is surrounded by a path of uniform width, as shown in the figure. If the area of the pool and the
path combined is 1520 square meters, what is the width of the path?
18
20
20+ 2x
18+2x
By solving a quadratic equation we can see that the width of the path measures 20 meters.
How to find the width of the path?
We know that the pool measures 18 meters by 20 meters, then the area of the pool alone is:
A = 18m*20m = 360 m^2
Now, if the path has a width x, then the rectangle that includes the path and the pool has dimensions:
(18m + 2x) and (20m + 2x)
And its area is given by:
(18m + 2x)*(20m + 2x)
And we know it is equal to 1520 m^2, then (i'm not writting the units in the computation):
(18 + 2x)*(20 + 2x) = 1520
360 + 4x^2 + 76x = 1520
Now we just need to solve that quadratic equation:
4x^2 + 76x - 1520 + 360 = 0
4x^2 + 76x - 1160 = 0
The solutions are:
x = (-76 ± √(76^2 - 4*4*(-1160))/(2*4)
x = (-76 ± 156)/4
We only care for the positive solution, which gives:
x = (-76 + 156)/4 = 20
We conclude that the width of the path measures 20 meters.

Answers:
A ' = (-3, -3)
B ' = (1, 0)
C ' = (2, -6)
=====================================================
Explanation:
To translate 6 units to the left, we subtract 6 from each x coordinate.
For point A, we have x = 3 become 3-6 = -3 as the new x coordinate.
Point A also goes down 7 units, in which we subtract 7 from the y coordinate. So the y coordinate of point A, which is 4, becomes 4-7 = -3 as the new y coordinate.
This is how we can write out the work shown for moving point A
[tex](\text{x},\text{y})\to(\text{x}-6,\text{y}-7)\\\\(3,4)\to(3-6,4-7)\\\\(3,4)\to(-3,-3)[/tex]
Point A is at (3,4) and moves to A ' which is at (-3, -3)
Do similar steps for points B and C to get the answers shown above.
