If triangles MNP is an equilateral triangle, find x and the measure of each side.
Answers
The value of x = 13
Each side of the equilateral triangle is: 27 units.
What is an equilateral Triangle?A triangle is classified or defined as an equilateral triangle if all its sides are of the same length. This means, all equilateral triangles have side lengths that are congruent.
Since triangle MNP is said to be an equilateral triangle, all its sides would be equal to each other. Therefore:
MN = NP = MP
Given the following:
MN = 4x - 25
NP = x + 14
MP = 6x - 51
Thus:
MN = NP
Substitute
4x - 25 = x + 14
4x - x = 25 + 14
3x = 39
x = 39/3
x = 13
MN = 4x - 25 = 4(13) - 25 = 27
MN = NP = MP
NP = 27
MP = 27

What is a parabola in math?
Drawing a parabola for the quadratic function f(x) = ax2 + bx + c results in a U-shaped curve.When an is smaller than zero, the parabola's graph is downward (or opens downward).When the value of an is greater than 0, the parabola's graph ascends (or opens up). The locus of points in that plane that are equally spaced apart from the direct x and the focus is known as the parabola.A right circular conical surface and a plane parallel to another plane that is tangential to the conical surface intersect to form a parabola, which is also known as a conic section.A parabola's general equation is written as y = a(x - h)2 + k or x = a(y - k)2 + h.Vertex here is indicated by (h, k).The typical form is y = a(x - h)2 + k.-9(x_6)²_1

Thus, it is clear that the lines RS and TV in the preceding diagram are parallel to each other
What are the properties of parallel lines?If you extend a set of lines indefinitely, they will remain parallel and never cross each other even though they are on the same plane. The symbol || represents the collection of parallel lines. All parallel lines are always equally spaced apart. Investigate the characteristics of parallel lines.
When two lines in a plane are stretched infinitely in both directions and do not cross, they are said to be parallel.
To solve the given question we know,
angle 1= angle 2 and lines RV // TS
angle 4= angle 3(interior angles on parallel lines are equal)
angle 1=angle 4 (vertically opposite angles are equal )
angle 1= angle 3 (angle 4=angle 1)
angle 4=angle 2( angle 1=angle 4)
Now we can see that the sum of base angles of the diagram will be 180 because
180-angle 3= angle STV
angle 4=angleSTV+180 (angle 3=angle4)

What is the distance from Point B (-1, 11) to line y = -1/3x - 6?
Answer in simplest radical form
Answers
The distance from Point B (-1, 11) to line y = (-1 ÷ 3x) - 6 is 15.811.
The distance from the point B(-1 , 11) to the line y= (-1 ÷ 3x) - 6 is given by the distance formula d = (|Ax1 + By1 + C|) ÷ (√(A² + B²)).
Comparing the equation y= (-1 ÷ 3x) - 6 with the standard forms Ax + By+ C = 0.
It is clear that the coefficient of x, A = -1 ÷ 3.
The coefficient of y, B = -1. The constant C = -6 and the points x1 = -1 and y1 = 11.
Substituting these data in the equation the distance d = (|(-1÷3)×(-1)+ (-1)×11 + (-6)|) ÷ √((-1 ÷ 3)² + (-1)² ) solving the equation the distance d becomes,
d = 15.811.

What are fractions?Fractions are used to depict the components of a whole or group of items. Two components make up a fraction. The numerator is the number that appears at the top of the line. It specifies how many identically sized pieces of the entire event or collection were collected. The denominator is the quantity listed below the line. The total number of identical objects in a collection or the total number of equal sections that the whole is divided into are both displayed. A fraction can be expressed in one of three different ways: as a fraction, a percentage, or a decimal. The first and most popular way to express a fraction is in the form of the letter ab.

At the local food stand, the vendor sells small drinks for $1.25 each and large drinks for $2.50 each. They sold 155 drinks today and made $265. How many small drinks and how many large drinks did they sell?
Answers
Answer:
98 small drinks and 57 large drinks.
Explanation:
Let's call x the number of small drinks and y the number of large drinks.
If they sold 155 drinks, we can write the following equation:
x + y = 155
In the same way, they made $265, so
1.25x + 2.50y = 265
Because each small drink cost $1.25 and each large drink cost $2.50.
Now, we can have the following system of equations
x + y = 155
1.25x + 2.50y = 265
Solving the firs equation for y, we get:
x + y - x = 155 - x
y = 155 - x
Replacing this on the second equation:
1.25x + 2.50y = 265
1.25x + 2.50(155 - x) = 265
Then, solving for x, we ge:
1.25x + 2.50(155) - 2.50(x) = 265
1.25x + 387.5 - 2.50x = 265
-1.25x + 387.5 = 265
-1.25x + 387.5 - 387.5 = 265 - 387.5
-1.25x = -122.5
-1.25x/(-1.25) = -122.5/(-1.25)
x = 98
Finally, we can find the value of y replacing x = 98
y = 155 - x
y = 155 - 98
y = 57
Therefore, they sell 98 small drinks and 57 large drinks.

What is meant by inverse function?An inverse in mathematics is a function that "undoes" another function. In other words, if f(x) yields y, then y entered into the inverse of f yields the output x.
Given: P(m) = (m/6) + 9
Determine the inverse function
P(m) = (m/6) + 9
Represent P(m) as P
P = (m/6) + 9
Swap the positions of P and m
m = (p/6) + 9
We are to make p the subject.
Subtract 9 from both sides, then we get
m - 9 = (p/6) + 9 - 9
m - 9 = (p/6)
Multiply through by 6
6(m - 9) = (p/6) × 6
simplifying the above equation, we get
6(m-9) = p
6 m-54 = p
Rearranging the above equation, we get
p = 6m - 54
Swap the positions of P and m
m = 6p - 54
m(p) = 6p - 54

[tex]x+9=-4x-6[/tex]Now, add 4x to both sides
[tex]\begin{gathered} x+4x+9=-4x+4x-6 \\ 5x+9=-6 \end{gathered}[/tex]Subtract 9 from both sides
[tex]\begin{gathered} 5x+9-9=-6-9 \\ 5x=-15 \end{gathered}[/tex]Divide both sides by 5
[tex]\begin{gathered} \frac{5x}{5}=\frac{-15}{5} \\ x=-3 \end{gathered}[/tex]Substitute x by -3 in equation (1) to find y
[tex]\begin{gathered} y=-3+9 \\ y=6 \end{gathered}[/tex]The solution of the system is (-3, 6)
Write the following expression in its simplest form-2/3(9/2x + 15/2)
Answers
Given the expression
-2/3(9/2x + 15/2)
Open the parenthesis;
= -2/3(9/2 x) - 2/3(15/2)
= -18x/6 - 30/6
= -3x - 5
Hence the expression in its simplest form is -3x - 5

Answers
In the given illustration, angle 1 and angle 2 are corresponding angles.
Note that corresponding angles in parallel lines are congruent.
angle 1 measures (63 - x)
angle 2 measures (72 - 2x)
Since both angles are congruent with each other, equate the angles :
[tex]\begin{gathered} 63-x=72-2x \\ \text{Solve for x, put the variables to the left side and the constant to the right side :} \\ -x+2x=72-63 \\ x=9 \end{gathered}[/tex]The measure of angle 1 will be :

Answer:
y = -2x + 2
Step-by-step explanation:
so to find the slope of the graph we must do (rise)/(run)
when we see the graph we see that when it goes DOWN 2 it also goes RIGHT 1
RISE is up or down
RUN is left or right
since it is down it is negative
so
-2 / 1
that is just -2
that is the slope
the equation for slope intercept is y = mx + b where m is the slope and b is the y intercept
so far it is y = -2x + b
the y intercept is where it crosses the y axis
that point is 2 based off of the graph
so
y = -2x + 2 is your answer

The solution of the inequality is [tex]x \geq 289[/tex].
What is inequality?
Inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign ( [tex]\neq[/tex]) " to indicate that two values are not equal. But several inequalities are utilised to compare the numbers, whether it is less than or higher than.
The given inequality is, [tex]\sqrt{x} \geq 17[/tex]
Taking square on both sides, we get
[tex]x\geq 289[/tex].
Therefore, the solution of the inequality is [tex]x \geq 289[/tex].

crate A exerts a force of 8320N and a pressure of 64N/cm2. crate B exerts a force of 9860N and a pressure of 29N/cm2. find the difference between the base areas of the crates in cm2
Answers
Answer:
difference in base areas = 210 cm²
Step-by-step explanation:
In order to calculate the difference in the base areas of the crates, we first need to find the base area of each crate.
To calculate the base area, we can use the formula for pressure and rearrange it to make area the subject:
[tex]\boxed{Pressure = \frac{Force}{Area}}[/tex]
⇒ [tex]Area = \frac{Force}{Pressure}[/tex]
Therefore:
•Base area of crate A = [tex]\mathrm{\frac{8320 \ N}{64 \ N/cm^2}}[/tex]
= 130 cm²
• Base area of crate B = [tex]\mathrm{\frac{9860 \ N}{29 \ N/cm^2}}[/tex]
= 340 cm²
Now that we know the base areas of each crate, we can easily calculate the difference between them:
difference = 340 cm² - 130cm²
= 210 cm²
