You can see that the value is decreasing by 6 every term. Because the rate is drawing at a constant rate the sequence must be linear, meaning that the slope is -6.
If we look at the general function of a line in slope intercept form:
[tex]y = mx + b[/tex]
where m is the slope and b is the y intercept. The trick to find the y intercept is to go backwards, in other words what was the previous term? 15+6=21. Therefore, m=-6 and b=21 and thus,
[tex]y = - 6 x+ 21[/tex]
Since we want to know the value of y even x=20 we obtain:
[tex]y = - 6(20) + 21 \\ \\ y = - 99[/tex]
Answer:
-99
Step-by-step explanation:
Given :
Arithmetic sequence : 15 , 9 ,3 , -3 , ........
To Find : 20th term .
Solution :
Formula of nth term in Arithmetic mean : [tex]a_{n} = a+(n-1)*d[/tex] ---(A)
where
a = first term of sequence
n = term position
d = common difference
[tex]a_{n}[/tex] = the term you want to find
Thus in the given sequence:
a = 15 ( first term )
n = 20 th term ( given )
d = 9-15 = 3-9 = -6(common difference)
Putting values in (A)
⇒[tex]a_{20} = 15+(20-1)*(-6)[/tex]
[tex]a_{20} = 15-114[/tex]
[tex]a_{20} = -99[/tex]
Hence the 20th term is -99 i.e. option 1

What is Proportion?
The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the proportion be represented as A
Now , the value of A is
The number of new houses = 3
The number of old houses = 7
So , the ratio of old houses to new houses = number of old houses : number of new houses
Substituting the values in the equation , we get
Ratio of old houses to new houses = 7 : 3
Now , the number of new houses = 15
So , the number of old houses A is given by the proportion equation ,
7 : 3 : : A : 15
On simplifying the equation , we get
7/3 = A / 15
Multiply by 15 on both sides of the equation , we get
A = ( 7 x 15 ) / 3
A = 7 x 5
A = 35 houses
Therefore , the value of A is 35 houses
Hence , the number of old houses is 35

Final answer:
The correct number of old houses is found by determining how many times the 3:7 ratio of new to old houses fits into the 15 new houses and then applying that to the 7 old houses in the ratio, which results in 35 old houses.
Explanation:
The question asks to find the number of old houses in a city given the ratio of new to old houses and the number of new houses. There is a ratio of 3 new houses for every 7 old houses. If there are 15 new houses, we need to find how many times the ratio fits into the number of new houses and then apply that same multiplier to the number of old houses.
To find this, we divide the number of new houses by the number of new houses in the ratio:
Number of times the ratio fits = 15 new houses ÷ 3 new houses per ratio = 5 times
Now, we multiply the number of old houses in the ratio by 5:
Number of old houses = 7 old houses per ratio × 5 times = 35 old houses
Therefore, the correct answer is B. 35.

Carlos swam to the bottom of a pool that is 12 ft deep. What is the opposite of Carlos's elevation relative to the surface
Answers
Answer:
The opposite of Carlos's elevation would be +12ft.
Step-by-step explanation:
This question is using positive and negative integers to represent elevation and descending. The surface of the pool would represent an elevation of 0, where we are level. However, when Carlos descends (swims to the bottom) of the pool, he is at an elevation of -12 because he is below the surface. The opposite of -12 would be +12. So the opposite of where Carlos is -12ft below the surface of the water would be +12 foot above the surface of the water.

How much in finance charges can he save by making the purchase on the last day of the billing cycle versus the first day of the billing cycle?
Answers
Answer:
$ 25.31 finance charges he can save by making the purchase on the last day of the billing cycle versus the first day of the billing cycle
Step-by-step explanation:
In the beginning of Month , ADB will be on the total amount of balance and the purchase that means ADB = 0.21 (2360 + 1500)/12
= $ 67.55
ADB at the end of the month
Part of 2360 for 27 days = (2360 x 27)/28 = $ 2275.71
Part of 3860 for 1 day = (3860 x 1)/28 = $ 137.85
So the total becomes $ 2275.71 + $ 137.85 = $ 2413.56
So , ADB will be $ 2413.56 x (0.21)/12

1) - Let's call:
x: number of days the company supposed to finish the order.
- You know that the company had to produce 40 items daily, but it produced 20 items more daily and finished the order 3 days ahead of time. Therefore, you can express this as following:
[tex]40x=(40+20)(x-3)\\40x=60(x-3)[/tex]

b) The percent that belongs to three people if six people share equally in an inheritance (because two of the people are disinherited) can be calculated as following:
[tex]\frac{3}{6}*100=50[/tex]%
c) - The increase goes from 1/8 to 1/6, therefore, you must subtract them:
[tex]\frac{1}{6}-\frac{1}{8}=\frac{1}{24}=0.04167[/tex]

If x varies inversely as y, and x = 11 when y = 15, find x when y = 3.
a:11/5
b:33/15
c:55
Answers
Answer:
55
Step-by-step explanation:
The equation of inverse variation is
y = k/x,
where k is a constant.
We can use the given x- and y-coordinates to find k.
y = k/x
15 = k/11
k = 165
The inverse variation equation for this problem is
y = 165/x
For y = 3,
3 = 165/x
3x = 165
x = 55
Answer:
C
Step-by-step explanation:
given x varies inversely as y then the equation relating them is
x = [tex]\frac{k}{y}[/tex] ← k is the constant of variation
To find k use the given condition x = 11 when y = 15
k = xy = 11 × 15 = 165 , hence
x = [tex]\frac{165}{y}[/tex] ← inverse variation equation
when y = 3, then
x = [tex]\frac{165}{3}[/tex] - 55 → C

Answers
Answer:
y=8
Step-by-step explanation:
We need to find the equation for the line.
The first step is to find the slope
We need 2 points (0,2) (2,3)
slope = (y2-y1)/(x2-x1)
= (3-2)/(2-0)
= 1/2
We know the y intercept ( where it crosses the y axis) at 2
Lets use the slope intercept form of the line
y= mx+b
y = 1/2 x+2
If we want to find the value of y when x =12 , substitute the value of x=12
y =1/2 * 12 +2
y = 6+2

How to plot a graph?A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.
In order to plot the graph, we need to find out y's values corresponding to x's value
As per the given function,
f(x) = (1/3)x
Substitute, x = 0,
y = f(0) = (1/3)0 = 0
So,(0,1) will not lie on the graph.
Similarly, (3, 27) and (−2, 9) also do not lie on the graph.
Substitute (-1,-1/3)
-1/3 = (1/3)(-1) = -1/3
Thus, it will be the point of the function.
Hence "The point which lies on the graph of f(x) = (1/3)x will satisfy the function thus point (-1, -1/3) will lie on the graph".

Determine the standard form of the equation of the line that passes through (-6,6) and (3,-2)
Answers
Considering the expression of a line, the equation of the line that passes through the pair of points (-66) and (3,-2) is 8/9x +y= 2/3.
Linear equation
A linear equation o line can be expressed in the form y = mx + b
where
x and y are coordinates of a point.m is the slope.b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.Knowing two points (x₁, y₁) and (x₂, y₂) of a line, the slope m of said line can be calculated using:
m= (y₂ - y₁)÷ (x₂ - x₁)
Substituting the value of the slope m and the value of one of the points in the expression y = mx + b, the value of the ordinate to the origin b can be obtained.
The standard form of the line is Ax +By= C
Equation in this case
In this case, being (x₁, y₁)= (-6, 6) and (x₂, y₂)= (3, -2), the slope can be calculated as:
m= (-2 - 6)÷ (3 - (-6))
m= (-2 - 6)÷ (3 + 6)
m= (-8)÷ 9
m= -8/9
Considering point 2 and the slope, you obtain:
-2= (-8/9)×3 + b
-2= -8/3 + b
-2 +8/3= b
2/3= b
The equation of the line is y= -8/9x +2/3.
Finally, the standard form of the line is 8/9x +y= 2/3
It takes 12 hours for a single hose to fill a large vat. When a second hose is added, the vat can be filled in 4 hours. How many hours are required for the second hose working alone to fill the vat?
Answers
6 hours
Step-by-step explanation:The two hoses together take 1/3 the time (4/12 = 1/3), so the two hoses together are equivalent to 3 of the first hose.
That is, the second hose is equivalent to 2 of the first hose. Two of the first hose could fill the vat in half the time one of them can, so 6 hours.
The second hose alone can fill the vat in 6 hours.
_____
The first hose's rate of doing work is ...
... (1 vat)/(12 hours) = (1/12) vat/hour
If h is the second hose's rate of doing work, then working together their rate is ...
... (1/12 vat/hour) + h = (1/4 vat/hour)
... h = (1/4 - 1/12) vat/hour = (3/12 -1/12) vat/hour = 2/12 vat/hour
... h = 1/6 vat/hour
so will take 6 hours to fill 1 vat.
The second hose can fill the vat alone in 6 hours, calculated by subtracting the work rate of the first hose from their combined work rate.
Explanation:The question is about the time it would take for the second hose to fill the large vat alone, given that the first hose takes 12 hours alone, but together they take 4 hours. We are not given any info about the hose size or flow rate, so those don't need to be involved here.
We can analyze this problem in terms of work done. We know that one hose can fill the vat in 12 hours, so its work rate is 1/12 of the vat per hour. When we add the second hose, the vat is filled in 4 hours. The combined work rate of both hoses is 1/4 of the vat per hour.
To find the work rate for the second hose, we subtract the work rate of the first hose from the combined work rate: 1/4 - 1/12 = 1/6. This means the second hose can fill the vat in 6 hours alone.

Work out the area of the shaded region.
Give your answer correct to 3 significant figures.
Answers
The shaded region, which is approximately 251.74 cm².
For the area of the shaded region, we need to calculate the area of a trapezium and the area of two semicircles.
Given data: AB = 28 cm , DC = 12cm and h = 14 cm
The formula for the Area of Trapezium:
Area of trapezium = 1/2 × (AB + DC) × h
Substituting the given values:
Area of trapezium = 1/2 × (28 + 12) × 14 = 280 cm²
The formula for the Area of a Semicircle:
Area of semicircle = πr²/2
Given that the radius r is 3 cm:
Area of two semicircles = 2 × π × 3²/2 = 28.26 cm²
Area of the Shaded Region:
Area of shaded region = Area of trapezium - Area of two semicircles
Area of shaded region = 280 - 28.26 ≈ 251.74 cm²
Therefore, the area of the shaded region is approximately 251.74 cm².

A delivery company purchased a new delivery truck for $43,200. The depreciated value of the truck can be estimated by the number of t years in service. If the the truck depreciates at a rate of $7,200 per year, which of the functions ƒ(t) could be used to estimate the truck's depreciated value after t years?
Answers
Answer:
[tex]f(t)=43,200-7200t[/tex]
Step-by-step explanation:
We have been given that a delivery company purchased a new delivery truck for $43,200. The depreciated value of the truck can be estimated by the number of t years in service. The truck depreciates at a rate of $7,200 per year.
This means that after t years truck will depreciate 7200t. To find the truck's depreciated value after t years we will subtract 7200t from the cost of new delivery truck (43,200).
[tex]f(t)=43,200-7200t[/tex]
Therefore, the function [tex]f(t)=43,200-7200t[/tex] could be used to estimate the truck's depreciated value after t years.
The depreciated value of the truck after t years can be estimated by the linear function ƒ(t) = 43200 - 7200t, reflecting a straight-line depreciation method at a rate of $7,200 per year.
To estimate the depreciated value of the delivery truck after t years, we can use a linear equation which reflects a straight-line depreciation method. Since the truck cost $43,200 and depreciates at a rate of $7,200 per year, the equation representing the depreciated value of the truck after t years would be ƒ(t) = 43200 - 7200t. This equation starts with the initial value of the truck and subtracts the depreciation cost multiplied by the number of years the truck has been in service.
Depreciation is a way businesses can allocate the cost of a physical asset over its useful life. In this case, each year the truck is in service, it loses $7,200 in value. After one year, the value of the truck would be $43,200 - $7,200, which equals $36,000, and you would continue to subtract $7,200 for each additional year to determine the truck's value at any given time.

P(X=2)=(42)(480)(522)
P(X=2)=61326=1221
In essence, this would give you the number of possible combinations of drawing two of the four ace cards in the deck (6, already enumerated by Ravish) over the number of possible combinations of drawing any two cards out of the 52 in the deck (1326). This is the way Ravish chose to solve the problem.
Another way is using simple probabilities and combinations:
P(X=2)=(4C1∗152)∗(3C1∗151)
P(X=2)=452∗351=1221
The chance of picking an ace for the first time (same as the chance of picking any card for the first time) is 1/52, multiplied by the number of ways you can pick one of the four aces in the deck, 4C1. This probability is multiplied by the probability of picking a card for the second time (1/51) times the number of ways to get one of the three remaining aces (3C1). This is the way Larry chose to solve the this.
Step-by-step explanation:
Hi There!
Answer:
4/52 (With cards picked before put back.)
3/48 (With cards picked before not put back.)
Step-by-step explanation:
A standard deck of cards is made up of 52 cards.
There are 4 kings in a deck.
4/52
Bob has a 4/52 chance of picking a king.
I don't know if the cards he picked prior to this he put back or not. If he didn't then it's 3/48.
Hope This Helps :)

[tex]2 \frac{5}{8} \div 2 \frac{1}{2} [/tex]
Change the mixed fractions to improper fractions.
To do this, multiply the whole number part by the denominator. Add that to the numerator. Then write the result on top of the denominator.
You would now have:
[tex] \frac{21}{8} \div \frac{5}{2} [/tex]
Change the division sign to a multiplication sign by turning the second fraction upside down.
That is,
[tex] \frac{21}{8} \times \frac{2}{5} [/tex]
The answer is:
[tex] \frac{42}{40} [/tex]
This can be simplified to:
[tex] \frac{21}{20} [/tex]
The simplest form of [tex]2\frac{5}{8}[/tex] ÷ [tex]2 \frac{1}{2}[/tex] is [tex]1\frac{1}{20}[/tex] .
Simplification: Consider,[tex]2\frac{5}{8}[/tex] ÷ [tex]2\frac{1}{2}[/tex]
write the mixed fraction to improper fraction
= [tex]\frac{21}{8}[/tex] ÷ [tex]\frac{5}{2}[/tex]
Now change the division sign to the multiplication sign by writing the second number as [tex]\frac{2}{5}[/tex] .
= [tex]\frac{21}{8}[/tex] × [tex]\frac{2}{5}[/tex]
= [tex]\frac{21}{20}[/tex]
Write the above improper fraction into a mixed fraction.
= [tex]1\frac{1}{20}[/tex]
