quilt squares are cut on the diagonal to form triangular quilt pieces. the hypotenuse of the resulting triangles is 16 inches long.what is the side of each piece. A.8in B.8and 3 in C.16and 2in D. 8and2in.
Answers
The right triangle formed is shown below
From the diagram,
x represents the side of the square. Recall that a square has equal sides
To find x, we would apply the pythagorean theorem which is expressed as
hypotenuse^2 = one leg^2 + other leg^2
From the diagram,
hypotenuse = 16
one leg = other leg = x
By substituting these values into the formula,
16^2 = x^2 + x^2
16^2 = 2x^2
256 = 2x^2
Dividing both sides by 2,
2x^2/2 = 256/2
x^2 = 128
Taking square root of both sides, we have
[tex]\begin{gathered} x\text{ = }\sqrt[]{128}\text{ = }\sqrt[]{2\times64}\text{ = }\sqrt[]{2}\text{ }\times\text{ }\sqrt[]{64} \\ x\text{ = 8}\sqrt[]{2} \end{gathered}[/tex]The correct option is 8√2 in

1) After the rise in popularity of the Croc shoe, a competitor brand will launch in January called “Srocs.” The company spends $9 to manufacture each pair of Sroc shoes. They also spend $8,000 on their Sroc-making machine and $4,000 on ads. One of the founders wants to sell each pair for $49 because that is the retail price for Crocs, but the other founder says they should sell the Srocs for $39.Write an equation for the company’s costs:Determine which price option you would choose and why.How much of the product must be sold to break even (using your chosen selling price)?
Answers
Company's costs:

For each manufactured pair of Sroc shoes = $9
We add them to find the cost equation in terms of x manufactured pair of Srocs:
[tex]\begin{gathered} C(x)=8000+4000+9x \\ \\ \Rightarrow C(x)=9x+12000 \end{gathered}[/tex]There are two options for the selling price:

The total number of toys sold if the daily sales of the toy is $6.50 is 2750 toys.
Functions and valuesEach element of X receives exactly one element of Y when a function from one set to the other is used. The sets X and Y are collectively referred to as the function's domain and codomain, respectively.
The independent values are known as the domain while the dependent are the codomain.
Given the function that represents the price-sales relationship for number of toys as;
y = 6000 - 500x
If the daily sales of the toy is $6.50, the total toys sold will be:
y = 6000 - 500 (6.50)
y = 6000 - 3250
y = 2750 toys

Answers
Our required probability is 99.82% or a 100%
%, which is a relative figure used to denote hundredths of any quantity. Since one percent (symbolized as 1%) is equal to one hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified. percentage.
What is the definition of percentage in statistics?
Percentages. The use of percentages to express statistics is one of the most popular. The word "percent" simply refers to "per hundred," and the sign for percentage is %. By dividing the whole or whole number by 100, one percent (or 1%) is equal to one hundredth of the total or whole.
Given that P(operational infection occurs at a 3% rate)
P(operational repair failures) = 17%
P(infection and failure happen simultaneously) = 2%
The first thing we'll discover is that P(infection or failure) is given by 0.03 + 0.17 - 0.02 = 0.18 = 0.18%.
Therefore, the probability that these procedures will be successful and infection-free is given by 100 - 0.18 = 99.82%.
Consequently, 99.82% of a probability is needed.

Define parabola.Any point on a parabola is at an equal distance from both the focus, a fixed point, and the directrix, a fixed straight line. A parabola is a U-shaped plane curve. The topic of conic sections includes parabola, and all of its principles are discussed here. A parabola is an approximately U-shaped, mirror-symmetrical plane curve in mathematics. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves. A parabola can be described using a point and a line.
Observe the illustration below. It depicts the paraboloid's vertical cross-section through its axis of symmetry.
Make the origin of the parabola the vertex.
Then, it has the equation y = bx².
The parabola crosses via (21,10), therefore
10 = b(21²)
= 0.0226
because
Its equation is y =0.0226²
For best reception, the receiver should be positioned at the paraboloid's focus point.
The focus has a y-coordinate of
a = 1/(4b)
= 1/0.0226
= 44.24 in
The receiver is situated 44.24 inches from the vertex, is the correct response.

[tex]\begin{gathered} y=-x^2+4x-3x+12 \\ y=-x(x-4)-3(x-4) \\ y=(x-4)(-x-3) \\ y=-1(x+3)(x-4) \end{gathered}[/tex]Hence, the intercept form of the equation is y= -1 (x + 3) ( x - 4 )
Find the slope and y-intercept of the graph of the linear equation. Give the y intercept in point form in the space provided. Use the equation editor to enter the slope if there are fractions. 5x - y = -5
Answers
The general equation of a line is:
y = mx + b
Here, y refers to how far up and x refers to how far along.
m is slop, that is the change in y to the change in x
and b is y intercept or the point where the value of x is zero.
So,
The given equation is:
5x - y = -5
The simplest step is to map the given equation with the standard equation (y = mx + b).
So,
- y = -5 -5x
Multiplying both sides by -1, we get
y = 5 + 5x
or
y = 5x + 5
Now, if we map this form with the standard equation (y = mx + b), we get
m = 5 and b = 5
Therefore, the slope (m) is equal to 5.
Also, y-intercept (b) is equal to 5.

Answers
Let's analyze the statements to see which one is not true.
Statement F. The coffee shop company had opened 400 stores by the end of 1992.
The horizontal axis on the graph (the x-axis) represents the number of years that have passed since 1992, thus the year 1992 is at x=0 on the graph.
The vertical axis (the y-axis) represents the number of stores.
As we can see in the following diagram, the red point represents the number of stores at x=0 (at the year 1992):
it is true that the coffee shop had 400 stores by the end of 1992.
Statement G. The coffee shop opened 100 stores in 1 year.
To see if this is true, we look at x=1, which represents 1 year, and check for the number of stores corresponding to 1 year:
This point is at (1,500) --> After 1 year there were 500 stores.
Since they started with 400 stores, this means that it is true that they opened 100 stores in 1 year.
Statement H. Every year the number of stores the coffee company opened increased by 25%.
We can find if this is true just by looking at the form of the graph. This graph has an exponential curve which means that the growth increases at every step. Thus there is an increase in the coffee shop that they open every year. This statement is true.
Statement J. Since 1992 the coffee shop company has opened 250 stores each year.
As we saw with the previous statement, the number of shops opened every year is not constant, it increases with time. Thus, since they do not open the same amount of shops every year, this option the one that is not true.
Answer: Statement J
