In the diagram below, QR is parallel to NO. If the length of NO is the same as the length of QP, NP=21, and QR=10, find the length of QP. Figures are not necessarily drawn to scale. State your answer in the simplest radical form, if necessary.
Using properties of Similar triangles, The measure of QP is 14.49.
Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent.
Similar triangles differ in size but have the same shape. Corresponding angles are identical in similar triangles. Similar triangles have corresponding sides that have the same ratio. The ratio of the square of any two of their corresponding sides to any identical triangle's area is the same.
Given two triangles,
ΔPQR and ΔPNO are Similar,
So, their sides are present in the ratio -
NO / QR = NP / PQ
We are given, QR = 10
NP = 21
On putting the values in the NO / QR = NP / PQ equation,
⇒ NO / 10 = 21 / QP
As NO = QP (given)
We can write as -
QP / 10 = 21 / QP
⇒ QP² = 10 × 21
⇒ QP² = 210
⇒ QP = 14.49

What is the definition of the sine ratio in a right triangle?.
The ratio of the side of a right-angled triangle opposite to a specified angle to the hypotenuse; when expressed as a real number between 0 and 1, it defines the sine of the angle.
What is the sine ratio in a right triangle?.Whenever the ratio is found by using the opposite side and the hypotenuse, we call it sine ratio.
We then say that sine 45 degrees is equal to 0.707. In short, we can use the symbol sin instead of sine and write sin (45 degrees) = 0.707
In general, sine of angle A = length of leg opposite angle A / hypotenuse
sin(A) = opposite/hypotenuse
In a right triangle, the sine of an angle is the ratio of the length of the opposite side divided by the length of the hypotenuse.

A store has a 25% discount now the cost is 34.50 what was the original price of the item
Answer:
$46
Step-by-step explanation:
We already have our first value of 34.5 and the second value of 75. Let's assume the unknown value is Y which answer we will find out.
As we have all the required values we need, Now we can put them in a simple mathematical formula as below:
STEP 1
34.5 = 75% × Y
STEP 2
[tex]34.5 = \frac{75}{100} *Y[/tex]
Multiplying both sides by 100 and dividing both sides of the equation by 75 we will arrive at:
STEP 3
[tex]Y = 34.5 *\frac{100}{75}[/tex]
STEP 4
Y = 34.5 × 100 ÷ 75
STEP 5
Y=46
Answer:
The original price is 46
Step-by-step explanation:
The x be the original price of the item.
The discount is 25%
x - .25x = 34.50
.75x = 34.50
Divide each side by .75
x = 34.50/.75
x = 46
The original price is 46
What equation has many solutions?.
An equation with infinite solutions has both sides equal.
We know that a solution of an equation is a value that satisfies given equation.
As we know the system of equations has infinitely many solutions if the system of lines are coincident, and if they have the same y-intercept.
In some equations, any value for the variable makes the equation true. This means, an equation has infinitely many solutions.
Consider the equation 5x + 13 = 3x + 13 + 2x
5x + 12 = 5x + 12 .....(combine like terms)
13 = 13 ........(subtrsct 5x from each side)
As we know 13 = 13 is always true.
To check that above equation has an infinite number of solutions, we try substituting some different values for x
For x = 3
5(3) + 13 = 3(3) + 13 + 2(3)
15 + 13 = 9 + 13 + 6
28 = 28
The statement 28 = 28 is always true. So, x = 3 is a solution.

Tony bakes a casserole for 25 5/12 minutes. He decides it needs to bake longer. He bakes it for another 2 3/6 minutes. How long does the casserole bake altogether?
The total time that Tony bakes the casserole is calculated by adding the two times together.
The first time the casserole bakes for 25 5/12 minutes and the second time it bakes for 2 3/6 minutes. The two times can be written in fractions as 25 5/12 + 2 3/6. To add fractions with different denominators, the denominators must first be made equal.To accurately calculate the total amount of time the casserole bakes, the fractions must be converted to their equivalent value in the same unit. 5/12 minutes is equal to 10/24 minutes and 2 3/6 minutes is equal to 8/6 minutes. To add the two fractions, 10/24 and 8/6, they must be converted to have the same denominator. The least common denominator is 24, so 10/24 is equal to 5/12, and 8/6 is equal to 16/24. To make the denominators equal, the common denominator of 12 must be used. 25 5/12 can be rewritten as 225/12 and 2 3/6 can be rewritten as 15/12. 225/12 + 15/12 = 240/12. The fraction 240/12 can be reduced to 20/1. Therefore, the total time that Tony bakes the casserole is 20 minutes. The formula used to calculate this time is (25 5/12) + (2 3/6) = (225/12) + (15/12) = (240/12) = (20/1).

What two numbers multiply to -24 and add 36
Two numbers are: - 36.65 and 0.655. This can be solved by using the concept of equation.
What is an equation?An equation is an algebraic expression that proves two mathematical expressions are equal in algebra, and this is how it is most commonly used. For instance, the equation 7x + 14 = 35 consists of the two equations 7x + 14 and 35, which are separated by the 'equal' sign. The point-slope form, standard form, and slope-intercept form are the three main types of linear equations.
By deleting parenthesis and grouping like words, each side of the equation may be made simpler. The changeable item on one side of the equation can be separated using addition or subtraction. To determine the variables, apply divisions or multiplication.
Given that,
two numbers multiply to -24 and add 36.
Let, two numbers are: x and y
Now, xy = -24 ............. (1)
or, y = - 24/x
x + y = 36 .............. (2)
Next, put y = - 24/x in equation no. (2) we get -
x + (-24/x) = 36
or, x² - 24 = 36x
or, x² - 36x - 24 = 0
or, x = -36.65
so, y = (-24/x) = (-24/ - 36.65)

How do you write 1 more than a number?.
To write 1 more than a number, we use the mathematical operation of addition and the notation 1 + Number = N+1.
To write 1 more than a number, we need to use the mathematical operation of addition. Addition is the process of combining two or more numbers to find the total or sum.
In this case, we are given the number 1 and we are asked to find the number that is 1 more than it. To do this, we can use the mathematical notation: 1 + Number = N+1.
This notation means that we are adding 1 to a number, which results in N+1. The "+" symbol is the addition operator and it is used to indicate that we are performing an addition operation. The "=" symbol is used to indicate that the result of the addition is N+1.
Another way to write 1 more than a number is to use the phrase "1 plus a number". This phrase indicates that we are adding 1 to a number to get N+1.
Therefore, In short, to write 1 more than a number, we use the mathematical operation of addition and the notation 1 + Number = N+1. This means that we are adding 1 to a number, resulting in N+1. It can also be written as "1 plus N", indicating the same operation.

The area on the map in square centimetres is 64 cm².
The scale of the plan is 1:20, meaning that for every 1 unit of measurement on the plan, the corresponding measurement on the actual boat is 20 units.
If the actual area of the base of the boat is 0.64 m², then the area on the map will be:
(0.64 m²) * (1/20)² = 0.0064 m²
To convert this to square centimetres, we multiply by 10,000 (since 1 m² = 10,000 cm²):
0.0064 m² * 10,000 = 64 cm²

The scale of the map indicates the ratio of the linear dimensions of the map to the actual ones. Then the area of the map will correlate with the actual one, as with a scale square:
S map = S actual * (1:20)²
S map = 0.64 m² * 1/400
S map = 0.0016 m²
