The number of cans that can be recycled in 16 days, written in scientific notation is 2.6 x 10⁹.
What are Scientific notations?
The way through which a very small or a very large number can be written in shorthand. In scientific notations when a number between 1 and 10s is multiplied by a power of 10.
For example, 6,500,000,000,000 can be written as 6.5x 10¹².
Given to us
Average 113,204 aluminum cans are recycled in a minute.
Firstly, in order to find the number of cans that can be recycled in 16 days, we need to find the number of minutes in 16 days. we know that 1 day has 24 hours where each hour has 60 minutes. therefore,
Number of minutes in 16 days = 16 x 24 x 60
Number of minutes in 16 days = 23,040 minutes
As it is given that on an average 113,204 number of cans can be recycled in a minute, therefore,
Total number of can that can be recycled = 113,204 x 23,040
= 2,608,220,160
= 2.6 x 10⁹
Hence, the number of cans that can be recycled in 16 days, written in scientific notation is 2.6 x 10⁹.

Question 3 (Multiple Choice Worth 1 points)
(02.04 MC)
Choose the equation that represents a line that passes through points (-6, 4) and (2,0),
Previous Question
Answer:
y = 8
Step-by-step explanation:
The line that contains points (0, 8) and (8, 8) is a horizontal line in which every point has 8 as its y-coordinate.
Equation: y = 8
y=-1/2x+1 is the equation that represents a line that passes through points (-6, 4) and (2,0)
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
the equation of a line that contains the points (0,8) and (8,8)
Slope=0
We need to find the y intercept
8=b
y=8 is the equation of a line that contains the points (0,8) and (8,8)
Now let us find the equation that represents a line that passes through points (-6, 4) and (2,0).
m=0-4/2+6
=-1/2
Now find the y intercept
0=2(-1/2)+b
b=1
y=-1/2x+1 is the equation that represents a line that passes through points (-6, 4) and (2,0),
Hence, y=-1/2x+1 is the equation that represents a line that passes through points (-6, 4) and (2,0)

Answer:
JL ≈ 3.1
Step-by-step explanation:
Using the cosine rule
with JL = k , JK = l , KL = j , then
k² = j² + l² - (2jlcosK )
= 6² + 8² - ( 2 × 6 × 8 × cos20° )
= 36 + 64 - (96cos20°)
= 100 - 96cos20° ( take square root of both sides )
k = [tex]\sqrt{100-(96cos20)}[/tex] ≈ 3.1 ( to the nearest tenth )
that is JL ≈ 3.1

F represents the fee (in dollars) for climbing d meters.
F = 110 +0.12d
What is the increase in price for every 100 meters climbed?
Answer:
$12
Step-by-step explanation:
when d = 0, F = 110
when d = 100, F = 110 + (0.12 x 100) = 122
when d = 200, F = 110 + (0.12 x 200) = 134
etc.
Therefore, increase in price for every 100 meters climbed = 134 - 122 = 122 - 110 = 12

Step-by-step explanation:
each game of cribbage "binds" 4 people, each hand of chess 2 people.
15 games of cribbage means 15×4 = 60 people are playing. that leaves 0 people and therefore 0 games for chess.
2 games of chess means 2×2 = 4 people are playing.
that leaves 60-4 = 56 people for cribbage making 56/4 = 14 games of cribbage.
13 games of cribbage means 13×4 = 52 people are playing. that leaves 60-52 = 8 people for chess making 8/2 = 4 games of chess.
14 games of chess means 14×2 = 28 people are playing, that leaves 60-28 = 32 purple for cribbage making 32/4 = 8 games of cribbage.
0 people of cribbage means nobody is playing this game, that leaves all 60 people to play chess making 60/2 = 30 games of chess.

c) The area of a rectangle is 70 cm and it is 7 m broad. (i) Find its length (ii) Find its perimeter
Answer:
34cm
Step-by-step explanation:
[tex]Solution,\\\\Area=70cm^{2} \\\\Breadth(b)=7cm\\\\Now,\\\\Length=\frac{Area}{Breadth}\\\\Length=\frac{70cm^{2} }{7cm} \\\\Length=10cm\\\\Again,\\\\Perimeter=2(l+b)\\\\Perimeter=2(10cm+7cm)\\\\Perimeter=34cm[/tex]
The required length and perimeter of the rectangle are 7 cm and 34 cm respectively.
The rectangle is 4 sided geometric shape whose opposites are equal in lengths and all angles are about 90°.
Here,
Let the length of the rectangle be l,
Now,
According to the question,
Area of the rectangle, = l × w
70 = l × 7
l = 70 / 7
l = 10 cm
Now,
Perimeter of the rectangle = 2[l + w]
= 2 [10 + 7]
= 34 cm
Thus, the required length and perimeter of the rectangle is 7 cm and 34 cm respectively.

The Parks and Rec department has an opening for a Solver of Linear Equations. Since Leslie is great at solving systems of linear equations she zealously offers to give all candidates a quick demonstration. She finds the LU factorization of a 2000 x 2000 matrix in 78125 seconds. She then takes another 25 seconds to apply both triangular substitutions (backward and forward) to solve the system of equations Mx = y for a given vector Y.
The candidates are supposed to estimate (without actually running any code) the time it takes to factorize and efficiently solve a similar system of linear equations Ax =b, where A is a square matrix with dimension 500, given 30 different right-hand side b vectors.
Matrix are used to show data in rows and columns
The estimated time to efficiently solve the square matrix A is 4907.8125 seconds
How to estimate the time to solve matrix AThe given parameters are:
Matrix size = 2000 by 2000
Time = 78125 seconds
Substitution time = 25 seconds
The time to solve the matrix is dependent on the size of the matrix, while the substitution time is fixed
The size of the similar matrix is 500 by 500
The similar matrix is 1/16 smaller than the original matrix of 2000 by 2000.
So, the time to factorize the matrix is:
[tex]Time = \frac{1}{16} * 78125\ seconds[/tex]
[tex]Time = 4882.8125\ seconds[/tex]
The estimate of the time to solve the new matrix is the sum of the time to factorize it and the substitution time.
So, we have:
[tex]Total = 4882.8125\ seconds + 25\ seconds[/tex]
This gives
[tex]Total = 4907.8125\ seconds[/tex]
Hence, the estimated time to efficiently solve the square matrix A is 4907.8125 seconds

what are some equivalent ratios to 3:4.5
Answer:
Step-by-step explanation:
First, find the unit rate. Divide 4.5 by 3 to get 1.5. 3:4.5 = 1:1.5. Then, multiply 1.5 by any number to get an equivalent ratio. For example, 1.5 times 6 = 9, so an equivalent ratio is 6:9. Or, 1.5 times 10 = 15, so another equivalent ratio is 10:15.
A group of friends goes out to lunch and decides to split the bill. Their bill is $32. 50, plus they want to leave a 20% tip. The final amount will be split 4 ways. What is the amount each person will pay? $7. 50 $8. 15 $9. 20 $9. 75.
Percent counts the number of a quantity compared to another quantity's 100 amount. The amount each person would pay is given by: Option D: $9. 75
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
For the given case,
Bill for lunch = $32.50
Tip = 20% of bill = [tex]\dfrac{32.50}{100} \times 20 = \dfrac{32.50}{5} = 6.50[/tex] (in dollars)
Total amount = Bill + Tip = $39
This amount has to be divided in 4 equal part.
Thus, each part of those 4 parts would be [tex]\dfrac{39}{4} = 9.75[/tex] (in dollars).
Thus, the amount each person would pay is given by: Option D: $9. 75

The quadrilaterals JKLM and PQRS are similar.
Find the length x of PQ.
PLS HELP ME and dont give me the answer 2.4 its wrong
Answer:
[tex]x[/tex] = 2.8
Step-by-step explanation:
If the quadrilaterals are similar, then the ratios of corresponding sides will be equal:
KL : QR = 4 : 5.6 = 4 / 5.6 = 5/7
JM : PS = 7 : 9.8 = 7 / 9.8 = 5/7
LM : RS = 3 : 4.2 = 3 / 4.2 = 5/7
This shows that the ratio of KJ : QP = 5/7
KJ : QP = 2 : [tex]x[/tex] = 2 / [tex]x[/tex]
Therefore, [tex]\frac{2}{x}=\frac{5}{7}[/tex]
cross multiply: 14 = 5[tex]x[/tex]
Divide both sides by 5: [tex]x[/tex] = 2.8

Jamie has a rectangular pool that has a length of 12 feet and a
perimeter of 40 feet. What is the width of the pool?
Answer:
8 feetStep-by-step explanation:
Given,
Perimeter of a rectangular pool (P) = 40 feet
Length of the pool (l) = 12 feet
Let,
Width of the pool be = w
As we know,
Perimeter of a rectangle = 2(length + width)Therefore,
By the problem,
=> 2(l + w) = P
[On substituting the values of l = 12 and P = 40]=> 2(12 + w) = 40
[On multiplying 2 with 12 and w]=> 24 + 2w = 40
[On subtracting both sides with 24]=> 24 - 24 + 2w = 40 - 24
[On Simplifying]=> 2w = 16
[On Dividing both sides with 2]=> [tex]\frac{2w}{2}[/tex] = [tex]\frac{16}{2}[/tex]
[On Simplifying]=> w = 8
Hence,
The required width of the pool is 8 feet. (Ans)
Answer:
The Width of the pool would be 8 feet/ft. .
Step-by-step explanation:
According to the Question Given:
Perimeter = 40 ft/feet
Length of the pool = 12 ft/feet
To Find:
The width/breadth of the pool
Solution:
We know that,
[tex] \boxed{\tt \: Perimeter \: of \: Rectangle = 2(l + b)}[/tex]
So Put their values accordingly:
Perimeter of The Rectangle = 40Length[L] = 12[tex]\longrightarrow \tt \: 40 = 2(12 + b)[/tex]
We got an equation.By this method we can easily find the breadth/width of the pool.
Solve this equation:
[tex]\longrightarrow \tt40 = 2b + 24[/tex]
Flip the equation:
[tex]\longrightarrow \tt2b + 24 = 40[/tex]
Transpose 24 to the RHS[remember to change its sign]:[tex]\longrightarrow \tt2b = 40 - 24[/tex]
Simplify:[tex]\longrightarrow \tt2b = 16[/tex]
Divide both sides by 2:
[tex] \tt\longrightarrow \cfrac{2b}{2} = \cfrac{16}{2} [/tex]
Use Cancellation method and cancel LHS and RHS:[tex]\tt\longrightarrow \cfrac{ \cancel2 {}^{1} b}{ \cancel2} = \cfrac{ \cancel{16} {}^{8} }{ \cancel2} [/tex]
[tex]\longrightarrow \tt1b = 8[/tex]
[tex]\longrightarrow \tt{b} =\boxed{\tt 8 \: feet}[/tex]
Hence, the breadth/width of the pool would be 8 ft./feet .
