A coach spent $975.84 on new uniforms for his team. If he bought uniforms for 16 players, how much did each uniform cost? Use r to represent the price of each uniform.
Answer: for each of the players' uniform it would be $60.99
Step-by-step explanation:
so here would be the equation written out.
975.84=16x
so, to get x by itself you would need to divide by 16.
x=60.99
How do we get our voice?
Answer: The lungs provide the airstream which powers human voice. As air is pushed up the windpipe from the lungs, the larynx, which is made up of two vocal folds, opens and closes to produce vibrations. These vibrations are carried through to the throat, nose, and mouth, which act as resonators- morphing the vibrations into distinct human sounds.
Step-by-step explanation:
Answer:
Our vocal cords gve us our voice.
Step-by-step explanation:
The vocal folds (cords) produce sound when they come together and then vibrate as air passes through them during exhalation of air from the lungs. This vibration produces the sound wave for your voice.
What is the quadratic equation??
Plsss reply I’ll mark as brainliest
Hello !
1. A quadratic equation results in the form: ax² + bx + c
2. Calculate the discriminant: Δ = b² - 4ac
3. Calculate x with the dicriminant: (-b ± √Δ) / 2a
Example:
3x² + 7x - 2 = 0 is a quadratic equation.
x = (-b ± √(b² - 4ac)) / 2a
= (-7 ± √(7² - 4*3*(-2))) / (2*3)
= (-7 ± √73)/6
A segment has a midpoint at (2,-7) and an endpoint at (8,-5). What what are coordinates of the other midpoint
The coordinates of the other endpoints is (-4, -9).
What is midpoint of a line segment?The midpoint of a line segment is given as,
x = (a + c)/2
y = (b + d) / 2
Where (x, y) is the midpoint and (a, b) and (c, d) are the two endpoints.
We have,
Midpoint: (2, -7) = (x, y)
Endpoints: (a, b) and (8, -5) = (c, d)
Now,
x = (a + c)/2
2 = (a + 8)/2
4 = a + 8
a = 4 - 8
a = -4
y = (b + d)/2
-7 = (b - 5)/2
-14 = b - 5
b = -14 + 5
b = -9
Thus,
The other endpoint is (-4, -9).

When the edge lengths of a rectangular prism are doubled volume is also doubled
When the edge lengths of a rectangular prism are doubled volume is also doubled
What is volume of a rectangular prism and how it change?The area occupied inside a rectangular prism is referred to as the volume of the prism. A polyhedron with two pairs of congruent and parallel bases is referred to as a rectangular prism. It has 12 sides, 6 faces (all of which are rectangles), and 8 vertices. Considering that the rectangular prism is a three-dimensional (3D) shape, the units cm3, m3, and so forth are employed to express the volume of the rectangle prism.
A rectangular prism is a polyhedron in geometry that has two parallel and congruent bases. It also goes by the name cuboid.
We are known that a rectangular prism's volume equals the product of its three dimensions, or volume = length width height.
If the height of the rectangular prism is doubled.
Its volume will be
l w (2h) = 2lwh = 2 v.
As a result, we can conclude that when the height of a rectangular prism doubles, so does its volume also doubled.

The town manager of Greenville wants to survey tax-paying residents for their opinion regarding increasing real estate taxes in
support of improvements to the sports field park on the west side of town.
Which method results in a random sample of the population?
A)Ask everyone that enters the Town Hall over the course of one month to complete a survey until 100 surveys have been
completed.
B)Randomly select 100 parents of parents that play soccer for the town, using the town's list of players and a random
number generator.
C)Survey every 10th person entering a supermarket on the east side of town until 100 surveys have been completed.
D)Randomly select 100 residents paying real estate taxes, using the town's list of taxpayers and a random number
generator.
By selecting 100 inhabitants who pay real estate tax, using the town's list of taxpayers and a random number generator, Option D offers an arbitrary population sample.
Why is this a random sample of the population?This approach guarantees that each taxpayer has an equal likelihood of being chosen for the study, resulting in a diversified sample representation.
Conversely, the other options have possible biases or restrictions; like surveying solely soccer player's guardians might narrow it down to one particular group or only conducting them in designated areas could lead to misrepresentation within the frame of the entire general opinion poll.

The given function is f(x)= x²+5, when x≤0
f(x)=2x when x>0
\(\lim _{x\to 0^-}\left(f\left(x\right)\right)\)
Which is \(\lim _{x\to 0^-}\left x^2+5\)
The given limit is a left hand limit as there is minus in the limits
When we apply x as 0 we get the value 5
Now \(\lim _{x\to 0^+}\left(f\left(x\right)\right)\)
So \(\lim _{x\to 0^+}\left 2x\)
The given limit is a right hand limit as there is positive in the limits

A space for storing boxes is 36 inches high. Each box is 6 inches high. A space of 9 inches must be left at the top. what is the maximum number of boxes that can be stacked in this space?
Answer:
Step-by-step explanation: 36-9 equals 27. You can only fit 4 evenly so thats the answer
The maximum number of boxes that can be stacked in the space of 36 inches keeping 9 inches on the top empty is 4.
What is Division?The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
Given that the height of the space in which boxes are needed to be stored is 36 inches high. Also, the height of the box is 6 inches.
But a space of 9 inches must be left at the top. Therefore, the space left to keep the boxes is,
Space left to keep the boxes = 36 inches - 9 inches
= 27 inches
Now, the number of boxes that can be put in the leftover space is,
Number of boxes = 27 inches / 6 inches
= 4.5
Since a half box can be placed in the space, therefore, the number of boxes that can be in the space is 4.
Hence, the maximum number of boxes that can be stacked in the space of 36 inches keeping 9 inches on the top empty is 4.

What is the quadratic formula?To solve quadratic equations of the form ax2 + bx + c = 0, use the quadratic formula. For this situation, your condition is as of now as a quadratic condition, with a = 2, b = - 12, and c = 20.
The quadratic formula is:
x = (-b ± √\((b^2 - 4ac)\)) / 2a
Plugging in the values for a, b, and c, we get:
x = (-(-12) ± √\(((-12)^2 - 4(2)(20)))\) / 2(2)
Simplifying the expression inside the square root:
x = (12 ± √\((144 - 160)\)) / 4
x = (12 ± √(-16)) / 4

How much would you have to deposit today to accumulate the same amount of money that $75 monthly payments at a rate of 3.5% compounding monthly for 10 years in an annuity would
earn?
Round to 2 decimal places and do not include the $
symbol.
Answer:
To calculate how much you would have to deposit today to accumulate the same amount of money that $75 monthly payments at a rate of 3.5% compounding monthly for 10 years in an annuity would earn, we can use the formula for the present value of an annuity due:
PV = PMT × ((1 - (1 + r/n)^(-n×t)) / (r/n)) × (1 + r/n)
where:
- PV is the present value of the annuity due (the amount you would have to deposit today)
- PMT is the monthly payment ($75)
- r is the annual interest rate (3.5%)
- n is the number of times interest is compounded per year (12 for monthly compounding)
- t is the number of years (10)
PV = 75 × ((1 - (1 + 0.035/12)^(-12×10)) / (0.035/12)) × (1 + 0.035/12) = **$7,360.47**
Therefore, you would have to deposit **$7,360.47** today to accumulate the same amount of money that $75 monthly payments at a rate of 3.5% compounding monthly for 10 years in an annuity would earn.

The measure of the angles for the similar triangles are ∠G = 105°; ∠H = 55° and ∠I = 20°
What are similar triangles?Two triangles are said to be similar if the ration of their corresponding sides are in the same proportion. Also, all their corresponding angles are congruent with each other.
From the diagram shown:
∠X + ∠Y + ∠Z = 180° (sum of angles in a triangle)
20 + 105 + ∠Z = 180
∠Z = 55°
Since triangle XYZ and triangle GHI are similar, hence:
∠X = ∠G = 105°; ∠Z = ∠H = 55° and ∠Y = ∠I = 20°
