Answer:
p=1/27
Step-by-step explanation:
3p=1/9
when 9 goes to the left land side divide changes into multiplication so 3p and 9 gets multiplied
3p*9=1
27p=1
when 27 goes the right hand side multiplication changes to division .So
p=1/27
The value of P is 1/27 for equation 3P = 1/9
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
Equation is 3P = 1/9
Three times of P equal to one by nine
We need to find the value of P
3P = 1/9
Divide both sides by nine
3P/3=1/9×1/3
P=1/27
Hence, the value of P is 1/27.

A 60-foot zip line from a tree to the ground forms a 45 degree angle of elevation from the ground. How high above the ground is the top of the zip line? Round your answer to the nearest tenth of a foot.
Answer:
42.4 foot
Step-by-step explanation:
Please check the attached image for a diagram explaining the question
We would use sine to determine the required side
Sin 45 = opposite / hypotenuse
0.7071 = opposite / 60
60 x 0.7071 = 42.4 foot
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero

[tex]x^2-x-6=0[/tex]
Answer:
x = - 2, x = 3
Step-by-step explanation:
Given
x² - x - 6 = 0
Consider the factors of the constant term (- 6) which sum to give the coefficient of the x- term (- 1)
The factors are + 2 and - 3 , since
2 × - 3 = - 6 and 2 - 3 = - 1 , then
(x + 2)(x - 3) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 3 = 0 ⇒ x = 3
Answer:
[tex]x^2-x-6=0[/tex]
[tex]\left(x+2\right)\left(x-3\right)=0[/tex][tex]x+2=0\quad \mathrm{or}\quad \:x-3=0[/tex][tex]x+2=0[/tex][tex]x+2-2=0-2[/tex] ← Subtract 2 from both sides[tex]x=-2[/tex][tex]x-3=0[/tex][tex]x-3+3=0+3[/tex] ← add 3 to both sides[tex]x=3[/tex]-----------------------

Answer:

Step-by-step explanation:
6x+1 = 9x-23
add 23 to both sides
subtract 6x from both sides
3x=24
x=8
Answer:
8 =x
Step-by-step explanation:
The angles are the same so
6x+1 = 9x-23
Subtract 6x from each side
6x+1-6x = 9x-6x-23
1 = 3x-23
Add 23 to each side
1 +23 = 3x-23+23
24 = 3x
Divide by 3
24/3 = 3x/3
8 =x

Step-by-step explanation:
Area of dirt in the flower bed = area of flowerbed - area of 3 trapezoids
Area of flowerbed:
The flowerbed is in the shape of a parallelogram
The area of a parallelogram can be calculated by multiplying the base length times the height
Base length = 20ft
Height = 10ft
Area of flowerbed = 10 * 20 = 200ft^2
Area of rockbeds
The rockbeds are in the shape of trapezoids
The area of a trapezoid can be calculated using this formula
A = (a + b)/2 * h
Where a and b = bases and h = height
The rockbeds of base lengths of 2 and 4 and have heights of 3
So area of rockbeds = (4 + 2)/2 * 3
4 + 2 = 6
6 / 2 = 3
3 * 3 = 9
We then multiply that by 3 ( because there are three rockbeds )
9 * 3 = 27
Finally we subtract the areas
200 - 27 = 173

Two similar triangles, the perimeter of the first is 74cm and the side lengths of the other one are 4.5cm 6cm and 8 cm. Find the length of the longest side of the first triangle.
Answer:
the longest side of the first triangle is 32 cm
Step-by-step explanation:
Given;
dimension of the smaller triangle = 4.5cm 6cm and 8 cm.
the longest side of this smaller triangle = 8 cm
Perimeter of the first triangle = 74 cm
let the increase in dimension of the similar first triangle = x
the longest side of the first triangle = 8x
4.5x + 6x + 8x = 74
18.5x = 74
x = 74/18.5
x = 4
the longest side of the first triangle = 8 x 4 = 32 cm
A triangle and a rectangle are shown below.
The area of the rectangle is 5 times the area of the triangle.
Work out the width(w) of the rectangle
Answer:
10 cm
Step-by-step explanation:
From the diagram,
Applying,
lw = 5/2(bh)..................... Equation 1
Where l = length of the rectangle, w = width of the rectangle, b = base of the triangle, h = height of the triangle.
make w the subject of the equation
w = 5(bh)/2l............... Equation 2
From the diagram,
Given: l = 12 cm, b = 6 cm, h = 8 cm
Substitute into equation 2
w = 5(6×8)/(2×12)
w = 10 cm
Hence the width of the rectangle is 10 cm

4x-18 = 2x+6 + 36
Combine like terms
4x-18 = 2x+42
Subtract 2x from each side
4x-18-2x =2x+42-2x
2x-18 =42
Add 18 to each side
2x-18+18 = 42+18
2x= 60
Divide by 2
2x/2 = 60/2

The points (30, 50). (-10, 30) and (-20, s) all lie on the same line. What is the value of s? Show your work.
Answer:
s = 25
Step-by-step explanation:
First we go from point (30, 50) to point (-10, 30).
Change in x: -10 - 30 = -40
Change in y: 30 - 50 = -20
Since a change in x of -40 results in a change in y of -20, we divide both changes by 4 to get:
a change of -10 in x results in a change of -5 in y.
Now we go from point (-10, 30) to point (-20, s).
The change in x is -20 - (-10) = -10
The corresponding chang ein y must be -5.
y = 30 - 5 = 25
Answer: s = 25
A 300$ mountain bike is discounted by 30%, and there is a 8% sales tax. Find the final cost of the mountain
Answer:
[see below]
Step-by-step explanation:
The bike's original price is 300 dollars. It has been discounted by 30%.
300 * 0.3 = 90
The price would be 90 dollars off.
300 - 90 = 210
$210 would be the subtotal.
There is also an 8% sales tax.
210 * 0.08 = 16.80
210 + 16.80 = 226.80
Hope this helps you!
Answer:
cost of the bike =$300
discount = 30%
Price of the bike ={ (30/100)×300}-300=210
Sales tax= 8%
Final cost =( 8/100)×210=16.80+210=226.80
