It would take 10 gardeners to plant 45 trees in 45 minutes.
Rule of ThreeIt's a math tool for solving problems about proportion. You can relate more than 2 variables and from the proportion, it's possible to find an unknown number.
The question gives:
6 gardeners can plant 18 trees in 30 minutes.
? gardeners can plant 45 trees in 45 minutes.
6 gardeners can plant [tex]\frac{18\; tree}{30\; min}=\frac{3}{5}[/tex] trees/min. You can calculate the second rate from [tex]\frac{45\; tree}{45\; min}=\frac{1}{1}=1[/tex] tree/min.
Write the previous text information in form of proportion.
6 gardeners ----------- 3/5 trees/min
x gardeners ----------- 1 tree/min
Then, applying cross multiplication:
[tex]\frac{3x}{5}=6\\ \\ 3x=30\\ \\ x=10[/tex]

Answer:
Step-by-step explanation:
An arithmetic sequence is represented by the recursive formula
a1=13
a^n=a^n−1 −7 .
What is the fifth term in the sequence?
a5=−8
a5=−15
a5=−22
a5=−35
The fifth term of the sequence is -15
Recursive functionsGiven the following recursive functions
[tex]a_1=13\\a^n=a^{n-1}- 7 .[/tex]
For the second term:
a2 = a1 - 7
a2 = 13 - 7
a2 = 6
For the third term:
a3 = a2 - 7
a3 = 6 - 7
a3 = -1
For the fourth term:
a4 = a3 - 7
a4 = -1 - 7
a4 = -8
For the fifth term:
a5 = a4 - 7
a5 = -8 - 7
a5 = -15

What is the 30th term of the linear sequence
-5 -7 -9 -11 -13
Answer:
the 30th term of the given linear sequence is -63.
Step-by-step explanation:
The given sequence is in arithmetic progression whose difference is given by:
-7 - (-5) = d
d = -2
The nth term in the arithmetic progression is given by the formula:
where 'n' is the number of terms, 'a' is the first term, is the nth term, and 'd' is the difference.
Now, substitute the known terms in the above formula.
So, the 30th term of the given linear sequence is -63.

Answer:
Design 1: $449.45
Design 2: $522.60
Design 3: $318.25
Design 3 as it's the cheapest
Step-by-step explanation:
Design 1
Area of a trapezoid = 1/2(a + b)h (where a and b are the bases and h is the height)
Given the slanted side = 3.5
Height = √(3.5² - 1²) = (3√5)/2
⇒ area of design 1 = 1/2(5 + 3) × (3√5)/2 = 6√5 = 13.42 m²
⇒ cost = 13.42 x 33.5 = $449.45
Design 2
Area of a triangle = 1/2 x base x height
Area of a rectangle = width x length
Area of a 6-sided regular polygon = 4 triangles + rectangle
⇒ area of design 2 = 4(1/2 × 1.4 × 2.0) + (2.5 × 4) = 15.6 m²
⇒ cost = 15.6 x 33.5 = $522.60
Design 3
Area of a trapezoid = 1/2(a + b)h (where a and b are the bases and h is the height)
⇒ area of design 3 = 1/2(3 + 2) × 2 + 1/2(3 + 1.5) × 2 = 9.5 m²
⇒ cost = 9.5 x 33.5 = $318.25

If sin 64° = p, determine the value of the following in terms of p.
8 sin 16º.cos 16º.cos32°
We are provided that [tex]{\sf \sin (64^{\circ})=p}[/tex] and we have to find the value of [tex]{\sf 8\sin (16^{\circ})\cdot \cos (16^{\circ})\cdot \cos (32^{\circ})}[/tex] . But let's recall a identity which is gonna be very helpful to do this question i.e
[tex]{\boxed{\sf 2\sin (\theta)\cos (\theta)=\sin (2\theta)}}[/tex]Now , coming back on the question ;
[tex]{:\implies \quad \sf 8\sin (16^{\circ})\cdot \cos (16^{\circ})\cdot \cos (32^{\circ})}[/tex]
[tex]{:\implies \quad \sf 4\{ 2\sin (16^{\circ})\cos (16^{\circ})\}\cos (32^{\circ})}[/tex]

Given the polynomial 8x3 6x2 − 32x − 24, what is the value of the constant 'k' in the factored form? 8x3 6x2 − 32x − 24 = 2(x k)(x − k)(4x 3) 4 3 2 1.
Constant 'k' has the value in the form of factored after factorization, the provided polynomial equation is 2.
What is polynomial equation?Polynomial equations is the expression in which the highest power of the unknown variable is n (n is real number).
The factor of a polynomial is the terms in linear or equation form, which are when multiplied together, give the original polynomial equation as result.
The given polynomial equation in the problem is,
[tex]8x^3 +6x^2 - 32x - 24[/tex]
The factor of the polynomial equation are given as,
[tex]2(x+ k)(x - k)(4x +3)[/tex]
First find out the factors to compare and find the value of k.The above equation has the unknown variable x and the highest power of this unknown variable is 3.
Take out the highest common factor 2, which can divide each term of the above equation (8, 6, -32, -24). Thus,
[tex]2(x+ k)(x - k)(4x +3)=2(4x^3 +3x^2 - 16x - 12)[/tex]
Take out the highest common factor to make the groups as,
[tex]2(x+ k)(x - k)(4x +3)=2(x^2(4x +3) - 4(4x + 3))\\2(x+ k)(x - k)(4x +3)=2(4x +3) (x^2 -4)\\2(x+ k)(x - k)(4x +3)=2(4x +3) (x^2 -2^2)[/tex]
Use the property of difference of the square for the (x²-2²) term as,
[tex]2(x+ k)(x - k)(4x +3)=2(4x +3) (x +2)(x-2)\\2(x+ k)(x - k)(4x +3)=2(x +2)(x-2)(4x +3)[/tex]
On comparing the two equation, we get the value of k as 3. Thus, the value of the constant 'k' in the factored form factorization the provided polynomial equation is 2.

she has a 3 out of 11 percent chance aka 3/11
Step-by-step explanation:
There is 1 red meaning there is less of a chance to get that one unless she is lucky same goes with purple! She has 2 brown flip flops so there is more of a chance she may get that one, but 4 pairs of pink flip flops meaning she is more likely to pick pink on Tuesday then Monday. but the answer can be 3/7 if I do not count the others flip flops... but hopefully this helps...

What is Equation of Graph of Polynomials?Graphs behave differently at various x-intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.
Identify the even and odd multiplicities of the polynomial functions' zeros.
Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.
The graphs cross or are tangent to the x-axis at these x-values for zeros with even multiplicities. The graphs cross or intersect the x-axis at these x-values for zeros with odd multiplicities
Given data ,
Let the parent function be represented as f ( x )
Now , the value of f ( x ) is
f ( x ) = x²
Now , the graph of the function is g ( x )
where g ( x ) = 4x²
And , the point P ( 1 , 4 ) lies on the graph

Find the specified vector 2v - 6w . Given v = 3i - 5j , w = - i + 4j ,
Answer:
Your question is unclear as to which product you're looking for, the dot product or the cross product, so I'll answer for both.
The i and j notations for vectors refer to their coordinates, e.g. a vector that is 2i+3j is one that moves 2 units in the x-direction and 3 units in the y-direction. This can also be notated as (2, 3), and that's the notation I'll be using in this answer to keep things simple.
In order to get either product, we have to do the subtraction in parentheses first:3v - 4w = 3 * (2, -2) - 4 * (0, -2). When multiplying a vector by a scalar number, you just multiply the coordinates by the scalar, so this becomes (6, -6) - (0, -8). Performing this subtraction by subtracting corresponding coordinates, we get 3v - 4w) = (6, 2). Also, 5u = 5 * (-3, 2) = (-15, 10).
Now, the dot product of two vectors is a scalar quantity. The dot product of the two vectors (-15, 10) • (6, 2) is the sum of the products of the corresponding coordinates. This is -15 * 6 + 10 * 2, which is -90 + 20, and that is -70.

7. If the willingness-to-pay distribution of a product is a negative exponential distribution with parameter λ, what is the price-response function associated with it?.
It can be deduced that the price-response function associated with the situation will be P = MWTP = -e⁻ λ.
What is a function?
A function, in mathematics, is a relationship that exists between one variable that is, the independent variable and the dependent variable.
When the willingness-to-pay distribution of a product is a negative exponential distribution with parameter λ, the price-response function associated with it will be:
dWTP/dλ = -e⁻ λ

A prism with a base area of 8 cm² and a height of 6 cm is dilated by a factor of 54. What is the volume of the dilated prism? Enter your answer, as a decimal, in the box. Cm³.
The volume of the dilated prism is calculated to be considering scale factor for the area as well as the height is 7558272 cm³.
What is the dilation or scale factor?The scale factor in the dilation of a mathematical object determines how much larger or smaller the image will be (compared to the original object).
Given that
The base area of prism = 8 cm²
Height of the prism = 6
Scale factor = 54
So enlarged area =( scale factor )² * previous area = 54²* 8 = 23328 cm²
Enlarged height = 54*6= 324 cm
Enlarged volume = enlarged area* enlarged height = 7558272 cm³
Thus, the volume of the dilated prism is 7558272 cm³.

The results of the survey are shown in the Venn diagram as,
Circles B and C overlap. Circle B contains 11, circle C contains 4, and the intersection contains 53. Number 23 is outside of the circles.Therefore, for circle B, it can be given as,
