Answer:
40 meters for area 1
12 meters for area 2 so combined it will be 52 meters
this one is hard
explanation is:
the length is 2m more than the width doubled and so the width is 6 so 6 times 2 is 12 + 2 (from the 2m longer) is 14 so then using the formula for rectangles (the shapes may be rectangles due to the lengths being different from the width) (length x 2) + (width x 2)= 40=28+12 and 6+12=18 now 18+ 40 combined gives us 52

I need help plzzzzzzz help24+4x=6x+2
Answer:
x = 11
Step-by-step explanation:
24+4x=6x+2
substract 2x from both sides 4x-4x and 6x -4x
24 = 2x + 2
Substract 2 from both sides 24-2 and 2-2
22 = 2x
Divide by 2 to both sides 22/2 and 2x/2
x = 11

Michelle will sell her homemade necklaces for $8 each at a craft fair. It costs her $150 for the booth rental at the craft fair.
She made 200 necklaces to sell.
Part B Michelle wants to graph the equation for her profit from selling her necklaces. The y-intercept of this graph will be
her profit from selling none of her necklaces.
What is the y-intercept of the graph of the equation that represents Michelle's profit from selling her necklaces?
Answer:
The y-intercept is y = -$150
Step-by-step explanation:
We know that:
Each necklace is sold for $8.
The total cost for Michelle is $150.
The profit equation is:
Profit = Revenue - Cost.
We already know that Cost = $150
The revenue will depend on x, the number of necklaces sold, so if each one costs $8, and she sells x of them, the revenue is:
Revenue = $8*x
Then the profit, as a function of x, is:
y = P(x) = $8*x - $150
Where y represents the profit.
Now we want to find the y-intercept of the profit equation, where the y-intercept is the y-value when we use x = 0
Then the y-intercept is:
P(0) = $8*0 - $150 = -$150
Also the graph of the equation can be seen below, where you need to remember that x can be any value in [0, 200] and only can be an integer.
So you only need to graph the line between x = 0 and x = 200.
Simplify 2x^2-7x-4/x^2-5x+4 What are the excluded values
Answer:
x = 1
Step-by-step explanation:
Given
[tex]\frac{2x^2-7x-4}{x^2-5x+4}[/tex] ← factor numerator and denominator
= [tex]\frac{(x-4)(2x+1)}{(x-4)(x-1)}[/tex] ← cancel (x - 4) on numerator/ denominator
= [tex]\frac{2x+1}{x-1}[/tex]
The denominator of the rational expression cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the value that x cannot be.
x - 1 = 0 ⇒ x = 1 ← excluded value

An 18-ft tall tree casts a shadow of 25 feet. Find the angle of elevation of the sun.
Answer:
46.05degrees
Step-by-step explanation:
Given the following
Height of tree = 18ft (Opposite)
length of shadow = 25ft (hypotenuse)
Required
Angle of elevation
Sin theta = opp/hyp
Sin x = 18/25
sin x = 0.72
x = arcsin(0.72)
x = 46.05
Hence the angle of elevation of the sun is 46.05degrees
An architect designs two similar triangular patios. The first patio has angle measures of (x + 5)°, (y + 15)°, and 80°. The second patio has angle measures of (x + 25)°, 40°, and 60°. Find the values of x and y. please answer fast! i just need this one!
Answer:
x = 55° and y = 25°
Step-by-step explanation:
Since we have two triangular patios with angles (x + 5)°, (y + 15)°, and 80° and the second patio has angles, (x + 25)°, 40°, and 60° respectively, and the sum of angles in a triangle is 180, we have that,
(x + 5)° + (y + 15)° + 80° = 180° and
(x + 25)° + 40° + 60° = 180°
Simplifying both expressions, we have
x + 5° + y + 15° + 80° = 180° and
x + 25° + 40° + 60° = 180°
collecting like terms, we have
x + y + 5° + 15° + 80° = 180° and
x + 25° + 40° + 60° = 180°
Adding the like terms, we have
x + y + 100° = 180° and
x + 125° = 180°
So,
x + y = 180° - 100° and
x = 180° - 125°
Thus,
x + y = 80° and
x = 55°
So, y = 80° - x = 80° - 55° = 25°
So, x = 55° and y = 25°

First add a diameter. The triangle \pink{ABD}ABDstart color #ff00af, A, B, D, end color #ff00af is isosceles as \pink{AB}ABstart color #ff00af, A, B, end color #ff00af and \pink{BD}BDstart color #ff00af, B, D, end color #ff00af are radii, so must be equal.

Graph the equation using the point and the slope.
y-4= 1/2(x-4)
Answer:
Look at the explanation
Step-by-step explanation:
From this equation, we know our point slope form: y-4= 1/2(x-4)
From here, we also know our point: (4,4)
Our slope is 1/2
We first plot (4,4) on the graph. Then we graph the slope by moving one space up from (4,4) and moving over two spaces.
Our graph would look something like this:

The perimeter of a rectangle is 202020 centimeters. The length is 666 centimeters. What is the area of the rectangle?
Answer: 24 cm²
Step-by-step explanation:
To find the area, first find the width of the rectangle.
Perimeter = (2 * Length) + (2 * Width)
20 = (2 * 6) + (2w)
20 = 12 + 2w
2w = 20 - 12
w = 8/2
w = 4 centimeters
Area = Length * Width
= 6 * 4
= 24 cm²

Write the standard equation of the circle if the center is (-1,2), and a point on the circle is (2,6).
Plz help me someone
Answer:
(x+1)²+(y-2)² = 25
Step-by-step explanation:
Standard equation of the circle is expressed as;
(x-a)²+(y-b)² = r²
(a,b) is the center of the circle
r is the radius
Get the radius
r = √(x2-x1)²+(y2-y1)²
r = √(2+1)²+(6-2)²
r = √3²+4²
r = √9+16
r = √25
r = 5
Substitute into the formula
(x-a)²+(y-b)² = r²
a = -1, b = 2, r = 5
(x-(-1))²+(y-2)² = 5²
(x+1)²+(y-2)² = 25
This gives the required equation

Answer:
( x + 2 )² + ( y - 1 )² = 25
Step-by-step explanation:
Circle equation - ( x - h )² + ( y - k )² = r²
Important notes:
(h,k) = center
r = radius
The first step would be to find the center
( it's hard to explain how to find the center point virtually but the center point is at (-2,1) )
Like stated before ( h , k ) = center point
* replace center point with (-2,1) *
( h , k ) = ( -2 , 1 )
h = -2
k = 1
* plug in the h and k values into the circle equation *
now we have ( x - ( -2) )² + ( y - 1 )²
Now to find the radius
We can find the radius by using the distance formula with the center point and any point on the circle's outline
The point chosen can vary but i chose (3,1)
Because the y value of the chosen point and the y value of the center are the same we can simply subtract the larger x value by the smaller x value to find the radius
3 - (-2)
the two negative signs cancel out
3 + 2 = 5
So the radius equals 5
* plug in the value of the radius into the equation *
Now we have
( x - (-2) )² + ( y - 1 )² = 5²
our final step is to simplify
- (-2) the two negative signs cancel out and it turns into +2
5² = 25
Our final answer would be ( x + 2 )² + ( y - 1 )² = 25

What is the approximate volume using 3 14 forx?
9514 1404 393
Answer:
5000π mm³ ≈ 15,700 mm³
Step-by-step explanation:
The volume of the cylinder is given by the formula ...
V = πr²h
For the given radius and height, the volume is ...
V = π(10 mm)²(50 mm) = 5000π mm³
Using 3.14 for π, the volume is ...
5000(3.14) mm³ = 15,700 mm³
