The number of tennis ball fit in the machine are 305 balls.
What is volume?Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.
Finding an object's volume can help us calculate the quantity needed to fill it, such as the volume of water needed to fill a bottle, aquarium, or water tank.
given dimensions of machine 15 x 15 x 14
volume of machine is 15 x 15 x 14 = 3150 cubic inches
and shape of ball is spherical,
with dia = 2.7 inches
radius of ball = 2.7/2 = 1.35 inches
volume of sphere is 4/3πr³
V = 4/3πr³
V = 4/3(3.14)(1.35)³
V = 4/3(3.14)(2.46)
V = 10.30 cubic inches
the area covered by 1 ball is 10.30 cubic inches
the number of ball in machine is 3150/10.30
the number of ball in machine = 305.82 = 305 approx
Hence 305 balls can be fit in machine.

[tex] \Large{\boxed{\sf x= 7 \pm 5i} } [/tex]
[tex] \\ [/tex]
Explanation:The given equation is a quadratic equation. In other words, it is written in the form ax² + bx + c = 0, where a ≠ 0.
[tex] \\ [/tex]
We will solve this equation using the quadratic equation, which is the following:
[tex] \sf x = \dfrac{- b \pm \sqrt{b^2 - 4ac}}{2a} [/tex]
[tex] \\ [/tex]
First, let's identify the value of the coefficients a, b, and c:
a = 1b = -14c = 74[tex] \\ [/tex]
Then, substitute these values into the quadratic formula:
[tex] \sf x= \dfrac{-(-14) \pm \sqrt{(-14)^2 - 4(1)(74)}}{2(1)} = \dfrac{14 \pm \sqrt{-100}}{2} [/tex]
[tex] \\ [/tex]
Simplify the expression knowing that [tex] \sf \sqrt{-1} = i [/tex], and keep in mind the following property:
[tex] \Large{\boxed{\sf \sqrt{ab} = \sqrt{a}\sqrt{b} }} [/tex]
[tex] \\ [/tex]
[tex] \sf x= \dfrac{14 \pm \sqrt{100 \times (-1) }}{2} = \dfrac{14 \pm \sqrt{100} \times \sqrt{-1}}{2} = \dfrac{14 \pm 10 \times i }{2} \\ \\ \implies \boxed{\boxed{\sf x= 7 \pm 5i}} [/tex]
[tex] \\ [/tex]
Therefore, the two complex conjugate roots of this equation are x = 7 + 5i and x = 7 - 5i.

Find a polynomial that represents the perimeter of the rectangle.
Hi there!
[tex]\large\boxed{P = 4x^2 + 12x + 22}[/tex]
The perimeter of a rectangle is:
P = 2l + 2w
Thus, plug in the given length and width:
P = 2(2x² + 5x + 8) + 2(x + 3)
Distribute:
P = 2(2x²) + 2(5x) + 2(8) + 2(x) + 2(3)
Simplify:
P = 4x² + 10x + 16 + 2x + 6
Combine like terms:
P = 4x² + 12x + 22
Answer:
[tex]4x^2+12x+22[/tex]
Step-by-step explanation:
The perimeter of a rectangle is equal to [tex]2l+2w[/tex] where l is the length and w is the width. So, this rectangle would be equal to [tex]2\left(x+3\right)+2\left(2x^2+5x+8\right)[/tex]. Then, to find the polynomial simplify the expression. To do this first distribute the two 2s. This equals [tex]2x+6+4x^2+10x+16[/tex]. Then, add like terms to finish simplifying.

If a pair of shoes was discounted from an original price of P5000 to P2800 what is the percent decrease or discount
Work Shown:
a = old price = 5000
b = new price = 2800
c = change in price
c = b-a
c = 2800-5000
c = -2200
The value of c is negative to indicate a price decrease.
d = percent change
d = (c/a)*100%
d = (-2200/5000)*100%
d = -44%
There is a 44% decrease or discount.
An unusually wet spring has caused the size of a mosquito population in some city to increase by 7 â% each day. If an estimated 18â0,000 mosquitoes are in the city on May 6. Find how many mosquitoes will inhabit the city on May 17 . Use y =18â0,000(1.07 )^ x where x is number of days since May 6 .
Answer:
378873
Step-by-step explanation:
Using the relation :
y = 180000(1.07)^x
x = Number of days since May 6 ;
y = Number of mosquitoes after x days
x = May 17- May 6 = 11 days
Therefore, number of mosquitoes inhabiting the city on May 17 will be :
y = 180000(1.07)^11
y = 180000 * 2.1048519522998348950643
y = 378873.351413970281111574
y = 378873 (nearest whole number).

A game is played with a spinner on a circle, like the minute hand on a clock. The circle is marked evenly from 0 to 100, so, for example, the 3:00 position corresponds to 25, the 6:00 position to 50 and so on. The player spins the spinner, and the resulting number is the number of seconds he or she is given to solve a word puzzle. If 100 players are randomly selected, what is the approximate probability that the average time these players will get to solve the puzzle is between 44 and 56 seconds
Answer:
P( 44 < X < 56 ) = 0.12
Step-by-step explanation:
Number of seconds one gets to solve the puzzle ( X )
E( X ) = 100 + 0 ) / 2 = 50
Var ( X ) = 833.3333
бx = √833.3333 = 28.868
Determine The approximate probability
P( 44 < X < 56 ) = Δ time given / number of players selected
P( 44 < X < 56 ) = (56 - 44) / 100
= 12 / 100 = 0.12

A parent function is a linear function of the form y=b true of false
False
Step-by-step explanation:The parent function is the simplest function within a family of functions that defines the general form of that family.
Parent Functions
Parent functions are given in terms of y and x, where y is the output and x is the input. In linear functions, b represents a constant, specifically the y-intercept. Since the form y=b does not have an input it cannot be the parent function of linear lines. The graph of y=b would be a horizontal line with no slope. This does not define the general form of most linear functions. Additionally, since the slope has been changed to zero, it is not considered the simplest form of linear functions.
Linear Parent Function
The true parent function of linear functions is y=x. This function is the simplest linear function and has no transformations. Additionally, when graphed it is a diagonal line that defines the general shape of lines.
To create new linear functions the parent function, y=x, can be transformed by changing the coefficient of x to change the slope or by adding a constant to shift the graph vertically.

Answer:
D
Step-by-step explanation:
we have 2 conditions
1. to be a multiple of 6
2. to be between 15 and 70
A and B are not correct because have numbers les than 15
C is not correct because the numbers keep on going passed 70
E is not correct because 70 is not a multiple of 6
D is correct because has both conditions meet

On one day at a local minigolf course, there were 320 customers who paid a total of $2,900. If the cost for a child is $7 per game and the cost for an adult is $10 per game, write a system of equations to model this scenario, where x represents the number of children and y represents the number of adults who played that day.
7x + 10y = 2900
x + y = 320
7x + 10y = 320
x + y = 2900
10x + 7y = 2900
x + y = 320
10x + 7y = 320
x + y = 2900
Brainiest for correct answer
A system of equations to model this scenario is given as follows -
x + y = 320
7x + 10y = 2900
What is expression?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.The general equation of a straight line is → y = mx + c{m} - slope {c} - intercept along the y - axis.
Given is that on one day at a local minigolf course, there were 320 customers who paid a total of $2,900. The cost for a child is $7 per game and the cost for an adult is $10 per game.
Let {x} represents the number of children and {y} represents the number of adults who played that day. We can write the given system of equations as -
x + y = 320
7x + 10y = 2900
Therefore, a system of equations to model this scenario is
x + y = 320
7x + 10y = 2900
