Answer:
The value of x is 55⁰.
Step-by-step explanation:
Let n be X,
(n+7)⁰+(3n-47)⁰=180⁰
or,n+7+3n-47=180
or,4n-40=180
or,4n=180+40

Step-by-step explanation:
the volume (V) of the prism is calculated as
V = lbh ( l is length, b is breadth, h is height )
here l = 13 , b = 2, h = 4 , then
V = 13 × 2 × 4 = 26 × 4 = 104 in³

A boating company has the following notice at the gate:
"Children under the age of 13 are not allowed to operate a boat".
Part A- Write an inequality to show the age of children who are allowed to operate a boat.
Part B- Describe in words how you can show the solution to this inequality of a number line.
Answer:
Part A:
x > 13
Part B:
How to show this inequality on a number line is a closed circle on 13, going left of 13.
Step-by-step explanation:
Part A:
x represents the age of children who are allowed to operate the boat.
Our inequality is < because if you are of the age of 13 you are allowed to operate the boat,
the inequality x > 13 reads x (the age of children) is greater than or equal to 13
Part B:
How to describe inequalities on a number line;
Closed circle: less than or equal to - or - greater than or equal to ( < , > )
Open circle: less than - or - greater than ( < , > )
To the right of the number on the number line: greater than
To the left of the number on the number line: less than
Answer:
Part A
Let x = age of child (in years)
Given:
"Children under the age of 13 are not allowed to operate a boat"
Therefore, children should be 13 or older:
⇒ x ≥ 13
Part B
Place a closed circle at 13.
Shade to the right of the closed circle.

The value of a company’s stock is represented by the expression x2 – 2y and the company’s purchases are modeled by 2x + 5y. The company’s goal is to maintain a stock value of at least $5,000, while keeping the purchases below $1,000. Which system of inequalities represents this scenario?
A. x2 – 2y > 5000
2x + 5y < 1000
B. x2 – 2y > 5000
2x + 5y ≤ 1000
C. x2 – 2y ≥ 5000
2x + 5y < 1000
D. x2 – 2y ≤ 5000
2x + 5y ≤ 1000
The system of equations that represents the situation is given by:
C. x² – 2y ≥ 5000, 2x + 5y < 1000
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In tis problem, the company's stock is represented by the expression x² - 2y, and the goal is a stock value of at least $5,000, hence the first equation is given by:
x² – 2y ≥ 5000
The purchases are represented by 2x + 5y, and the goal is to keep it below $1,000, hence the second equation is given by:
2x + 5y < 1000

What is the remainder when (x4 36) is divided by (x2 – 8)?
Answer:
(x4 36) I didn't that is . or + so I solved it on +
Hope that what you looking for :)
Step-by-step explanation:
BY Using the long divison method, x⁴ + 36 is divided by x² - 8 is 100
Dividend = x⁴ + 36
Divisor = x² - 8
_____x²+8
x² - 8 | x⁴ + 36
| x⁴ - 8x²
-8x² + 36
8x² - 64
_100
The remainder is calculated as (36 - (-64)) = (36 + 64) = 100
Therefore, the remainder is 100

How to find x and y? We didn’t study much about the rhombus at all
Answer:
answer can be any numbers but I will choose
x = 50° and y =130°
Step-by-step explanation:
We know all the inner degree of rhombus =360°
Then, x+y+x+y = 360°
or,2x + 2y = 360°
or, 2(x + y) = 360°
or, x + y = 360°/2
or,x + y = 180°
Let x = 50° then
50° + y = 180°
or, y = 180° - 50°
or, y = 130°
Find the maximum height of the equation -16x^2+64x+86=0
Answer:
max = 150
Step-by-step explanation:
the maximum height is the value of the y- coordinate of the vertex.
given a quadratic equation in standard form : y = ax² + bx + c = 0 ( a ≠ 0 )
then the x- coordinate of the vertex is
x = - [tex]\frac{b}{2a}[/tex]
- 16x² + 64x + 86 = 0 ← is in standard form
with a = - 16 and b = 64 , then
[tex]x_{vertex}[/tex] = - [tex]\frac{64}{-32}[/tex] = 2
substitute x = 2 into the quadratic for corresponding y- coordinate
- 16(2)² + 64(2) + 86 = - 16(4) + 128 + 86 = - 64 + 128 + 86 = 150
vertex = (2, 150 )
then maximum height is 150 units
Determine and state an equation of the line perpendicular to the lines 5x-4y=10 and passing through the point (5,12). in point-slope form.
Please help I will mark branilest!!! and give 100 points
The equation of the line in point-slope form is: y - 12 = -4/5(x - 5).
What is the Equation of a Line in Point-slope Form?It is given as, y - b = m(x - a), where (a, b) is a point on the line and m is the slope of the line.
Rewrite 5x-4y=10 in slope-intercept form:
-4y= - 5x + 10
y= -5x/-4 + (10/-4)
y = 5/4x - 5/2
The slope is 5/4
The line that is perpendicular to 5x-4y=10 will have a slope which is the negative reciprocal of 5/4, which is -4/5.
Substitute (5, 12) and -4/5 into y - b = m(x - a):
y - 12 = -4/5(x - 5) [point-slope form]

352,345,338,... Find the 43rd term
Step-by-step explanation:
it seems we are dealing with subtraction, as the differences between the 1st and second, and between the 2nd and 3rd numbers are equal : -7
so, we can assume that the sequence is created by always subtracting 7.
a1 = 352
a2 = a1 - 7 = 352 - 7 = 345
a3 = a2 - 7 = a1 - 7 - 7 = 352 - 7 - 7 = 338
an = an-1 - 7 = a1 - 7(n-1) = 352 - 7(n-1)
a43 = 352 - 7(43-1) = 352 - 7×42 = 352 - 294 = 58

How to estimate the amount of metal needed to produce a given amount of figures
According to this problem, we are required to determine the amount of metal needed to build three pieces with the dimensions presented in the figure.
In this case, we need to estimate the total surface area ([tex]A_{T}[/tex]), in square feet, required for the production of the three pieces, that is, the product of the number of pieces (n), no unit, and the surface area of each piece (A).
Now we proceed to calculate the total surface area:
[tex]A_{T} = n\cdot A[/tex]
[tex]A_{T} = 3\cdot \left[(5\,ft)\cdot (8\,ft) + (2\,ft)\cdot (8\,ft)+(8\,ft)\cdot (7\,ft)+(3\,ft)\cdot (8\,ft) \\[/tex]
