Solve the equation. 9 = –d + 17
Answer:
d = 8
Step-by-step explanation:
Since the variable appears on only one side of the equation, all terms not containing the variable can be eliminated from that side by adding their opposite to both sides of the equation. That is, add -17 to both sides of the equation:
9 -17 = -d + 17 - 17
-8 = -d . . . . . simplify
Now, the equation can be multiplied by a number that will give "d" on one side of the equation. Here, that number is -1. Multiply both sides of the equation by -1:
(-1)(-8) = (-1)(-d)
8 = d . . . . . simplify
The solution is d = 8.
Answer:
8
Step-by-step explanation:
[tex]9= -d +17\\9-17= -d +17- 17 \\-8/-1 = -d/-1\\8 = d[/tex]
The current area of the city park is represented by the expression 11x2 + 4x + 6. The city will expand the park this summer by a factor of 5x − 3. If one-fourth of the new park is to be wooded, which expression represents the new area of the park that is not wooded?
The new area of the park that will not be wooded after expansion is represented by the expression 41.25x³ - 24.75x² + 15x - 13.5.
Explanation:The current area of the park is given by the polynomial 11x² + 4x + 6. If the city expands the park by a factor of 5x - 3, the total new area of the park becomes (11x² + 4x + 6) * (5x - 3), which represents the expansion of the park.
However, the question asks for the part of the park that will not be wooded, which we know is three-fourths of the total park. So, we multiply our expanded park equation by 3/4 (or 0.75) to find this area:
(3/4) * [(11x² + 4x + 6) * (5x - 3)]
Using distributive property, we can further expand the expression:
=(3/4) * [(55x³ - 33x² + 20x - 18)]
So the area that will not be wooded after expansion is expressed as 41.25x³ - 24.75x² + 15x - 13.5.

#SPJ12
Given that the current area of the park is represented by a second degree equation, the expansion of the park will proportionally increase its area. The new area after expansion will be the product of the current area and the expansion factor, so we will need to multiply our current area, which is given by 11x^2 + 4x + 6, by the expansion factor, which is 5x - 3.
This will yield: (5x - 3)*(11x^2 + 4x + 6) as the total new area of the park.
Now that we've calculate the total new area of the park, we need to find out the area of the park that will be wooded and the area that will not be. We know that the wooded area will be one-fourth of the total area, so we can find this by dividing our total area by 4.
This yields: (5x - 3)*(11x^2 + 4x + 6) / 4 as the wooded area of the park.
After discovering the area that will be wooded, we can find the non-wooded area by subtracting the wooded area from the total area of the park.
Therefore, the new area of the park that is not wooded is given by:
3*(5x - 3)*(11x^2 + 4x + 6) / 4

A charity organization had a fundraiser where each ticket was sold for a fixed price of $ 70. They had to sell a few tickets just to cover necessary production costs. After selling 10 tickets, they were still at a net loss of $800, (due to the production costs). Let (n)P, denote the net profit from the fundraiser P (measured in dollars) as a function of the number of tickets sold n. Write the function's formula.
Answer: The function's formula would be
[tex]P(n)=Revenue-Cost\\\\P(n)=70n-1500[/tex]
Step-by-step explanation:
Since we have given that
Price of each ticket = $70
Number of tickets = 10
Total cost price of tickets would be
[tex]70\times 10\\\\=\$700[/tex]
After selling 10 tickets, there is a net loss of $800.
So, Total product cost would be
[tex]\$700+\$800\\\\=\$1500[/tex]
We need to write the function's formula for the number of tickets sold 'n'.
So, the function's formula would be
[tex]P(n)=Revenue-Cost\\\\P(n)=70n-1500[/tex]

What is the median of the following set?
28, 45, 12, 34, 36, 45, 19, 20
28
34
31
35
Answer:
Median = 31
Step-by-step explanation:
The median is the middle number which comes after arranging the set in ascending order.
Here, the given data is: 28, 45, 12, 34, 36, 45, 19, 20
The data arranged in the ascending order is as follows:
12, 19, 20, 28, 34, 36, 45, 45
Since the number of terms is even, we have two middle numbers, viz.,
28 and 34
The median would be the average of these two.
Therefore, Median = [tex]$ \frac{28 + 34}{2} $[/tex]
= 31
The answer is 31.
The median of the set 28, 45, 12, 34, 36, 45, 19, 20 is 31.
To find the median of a set of numbers, you should first arrange the numbers in ascending order and then locate the middle number.
If there is an even number of terms, the median is the average of the two middle numbers. Let's do that with the given set: 28, 45, 12, 34, 36, 45, 19, 20.
Sort the numbers: 12, 19, 20, 28, 34, 36, 45, 45.Find the middle: Since there are 8 numbers (an even amount), the median will be the average of the 4th and 5th numbers.Calculate the median: (28 + 34) / 2 = 31.Therefore, the median of the given set is 31.

Faelyn noticed that she does not have a common factor. Which accurately describes what Faelyn should do next?
Faelyn should realize that her work shows that the polynomial is prime.
Faelyn should go back and regroup the terms in Step 1 as (6x4 + 3x2) – (8x2 + 4).
In Step 2, Faelyn should factor only 2x out of the first expression.
Faelyn should factor out a negative from one of the groups so the binomials will be the same.
Answer:
(b) Faelyn should go back and regroup the terms in Step 1 as (6x⁴ + 3x²) – (8x² + 4)
Step-by-step explanation:
You want to know the next step in factoring 6x⁴ -5x² -4 after noticing the terms have no common factor.
TrinomialFaelyn can notice the variable terms are powers of x², meaning this expression is a quadratic in x². As such, it may be able to be factored using the same strategies available for factoring quadratic expressions.
One such strategy is to rewrite the middle term as a sum, then group the terms and factor each group. Faelyn has apparently noticed that she can rewrite -5x² as 3x² -8x². This means ...
Faelyn should go back and regroup the terms in Step 1 as (6x⁴ + 3x²) – (8x² + 4), choice B.
__
Additional comment
The values used to rewrite the x² term are factors of (6)(-4) = -24 that have a sum of -5. Those values are +3 and -8.
Once Faelyn has regrouped the terms, she can factor further as ...
(6x⁴ + 3x²) – (8x² + 4) = 3x²(2x² +1) -4(2x² +1) = (3x² -4)(2x² +1)
These two binomial factors are prime.
A map of Scotland is drawn to scale of 1:325,000.
how many CM on the map would show 65KM?
On a map of Scotland, drawn to the scale of 1:325,000, 65 KM of real-world distance will be represented by 20 cm on the map.
Explanation:The question pertains to the scale existing on a map. A map scale enables us to convert the measurements on the map into the corresponding real-world distances. Here, we have a map of Scotland that is drawn to the scale of 1:325,000. This signifies that 1 cm on the map equates to 325,000 cm in reality.
To ascertain how many cm on the map would represent 65 KM, we first need to convert 65 KM into cm. As we know, 1 KM is equal to 100,000 cm. Therefore, 65 KM will be equivalent to 65 * 100,000 = 6,500,000 cm.
Now, we divide the real-world cm (6,500,000 cm) by the scale (325,000), which gives us the cm on the map. Thus, 6,500,000 cm / 325,000 = 20 cm
So, on this map, 65 KM will be denoted by 20 cm.

Answer: The required sum is 504.
Step-by-step explanation: We are given to find the sum of the following arithmetic series using the formula for the sum of an arithmetic series :
[tex]\sum_{i=1}^{18}(2i+9).[/tex]
The given arithmetic series can be written, in expanded form, as follows :
[tex]11+13+15+17+~.~.~.~+43+45.[/tex]
We know that
the sum of first n terms of an arithmetic series with first term a and common difference d is given by
[tex]S=\dfrac{n}{2}\{2a+(n-1)d\}.[/tex]
In the given series, a = 11 and d = 13 - 11 = 15 - 13 = . . . =2.
Therefore, the sum up to 18 terms will be
[tex]S_{18}=\dfrac{18}{2}\{2\times 11+(18-1)\times2\}=9(22+34)=9\times56=504.[/tex]
Thus, the required sum is 504.
The sum of the arithmetic series ∑₁¹⁸(2i + 9) using the arithmetic series formula is 504.
To find what is the sum of the arithmetic series ∑₁¹⁸(2i + 9) below using the formula for the sum of an arithmetic series, we proceed as follows
The formula for the sum of therms of an arithmetic series is given by
Sₙ = n/2(a + Tₙ) where
n = number of termsa = first term and Tₙ = last termNow, since we have that arithmetic series, ∑₁¹⁸(2i + 9), the nth terms is U = 2i + 9
Now, the first term is when i = 1.
So, U₁ = a = 2(1) + 9
= 2 + 9
= 11
Also, the last term is when i = 18
So, U₁₈ = T₁₈ = 2(18) + 9
= 36 + 9
= 45
So, the sum of terms Sₙ is when n = 18
S₁₈ = 18/2(11 + 45)
= 9(56)

Taking into account the rule of three, the total distance that Ms. Wilson walked in 4 days is 3 miles.
Rule of threeIn first place, the rule of three is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.
That is, what is intended with it is to find the fourth term of a proportion knowing the other three.
If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other) , the direct rule of three must be applied.
To solve a direct rule of three, the following formula must be followed, being a, b and c known data and x the variable to be calculated:
a ⇒ b
c ⇒ x
