In order to find the number of empty bins, let's calculate how many packs will be made with the given material.
240 markers can be organized in 240/8 = 30 packs
320 crayons can be organized in 320/8 = 40 packs
336 colored pencils can be organized in 336/8 = 42 packs
In total we have 30 + 40 + 42 = 112 packs
Each bin can hold 8 packs, to in order to hold 112 packs, we need 112/8 = 14 bins.
We have 24 bins. Since 14 will be used, we will have 24 - 14 = 10 empty bins.

Step-by-step explanation:
Kim places $1,250 into a bank account that pays 4.25% simple interest. if she does not add or remove any money from the account, how much interest will she earn after 60 months (anwers must be written as money-rounded to the hundred to the place)
The rule of the simple interest is
[tex]I=P\times R\times T[/tex]P is the initial amount
R is the rate in decimal
T is the time in years
Since Kim places $1250, then
P = 1250
Since the rate is 4.25%, then
[tex]R=\frac{4.25}{100}=0.0425[/tex]Since the time is 60 months, divide it by 12 to change it to years
[tex]\begin{gathered} T=\frac{60}{12} \\ T=5 \end{gathered}[/tex]Substitute them in the rule above
[tex]\begin{gathered} I=1250\times0.0425\times5 \\ I=265.625 \end{gathered}[/tex]Round it to the nearest hundredth
I = $265.63
Reduce the algebraic fraction. y^3-3y^2+y-3/y^2-9
The reduce algebraic fraction is [tex]\frac{y^2 + 1}{y + 3}[/tex]
What is algebraic fraction?Algebraic fraction are simply fractions with algebraic expressions on the top and/or bottom
We follow the step to reduce to algebraic fraction
[tex]\frac{y^3 - 3y^2 -3 }{y^2 - 9}[/tex]
Simplify the numerator
[tex]\frac{ (y - 3) )(y^2 + 1 )}{y^2 -9}[/tex]
Factor out the greatest common factor from each group
[tex]\frac{(y^3 -3y^2 ) = y -3}{y^2 - 9}[/tex]
Find out greatest common factor (GCF) from each group
[tex]\frac{y^2 (y + 3) + 1 (y - 3)}{y^2 - 9}[/tex]
Simplify the denominator and rewrite 9 as [tex]3^{2}[/tex]
[tex]\frac{( y - 3 ) (y^2 + 1 ) }{y^2 - 3^2}[/tex]
Since both terms are perfect squares, factor using the difference of squares formula
[tex]a^{2}- b^2 = (a +b ) (a -b)[/tex] where a = y and b = 3
[tex]\frac{( y - 3) (y^2 + 1 )}{(y + 3 ) (y -3)}[/tex]
Evaluate the equation and rewrite the expression

Some of the children at a nursery arrive by car.
. 40% of the children at the nursery are boys.
70% of the boys at the nursery arrive by car.
• 60% of the girls at the nursery arrive by car.
What is the probability that a child chosen at random from the nursery arrives by car?
Answer:
Will assume that there are 100 kids.
100 x 40% =40 of them are boys
40 x 70% = 28 boys arrive by car.
100 - 40 = 60 - Number of girls in Nursery.
60 x 60% = 36 of them arrive by car.
28 boys + 36 girls = 64 - kids that arrive by car.
64 / 100 = 64% - probability of a randomly picked kid that he/she arrived by car.

Mr.Wells drew a plan for a rectangular dog run. The vertices are (2 1/3, 7 1/2), (12, 7 1/2),(12, 1) and (2 1/3, 1). What is the perimeter of the dog run?
Perimeter of rectangular dog run is 32.34 units.
Given,
Vertices of rectangular dog run are [tex](2\frac{1}{3},7\frac{1}{2} ), (12,7\frac{1}{2}), (12,1), (2\frac{1}{3},1 )[/tex]
Let
[tex]A=(2\frac{1}{3},7\frac{1}{2} )=(\frac{7}{3} , \frac{15}{2} } )\\ \\B=(12,7\frac{1}{2})=(12,\frac{15}{2} )\\\\ C=(12,1)\\ \\D=(2\frac{1}{3},1 )=(\frac{7}{3},1)[/tex]
A, B,C and D be the vertices of the rectangular dog run as shown in figure.
In rectangle opposite sides are equal. thus, AB=CD and BC=AD
In this rectangle, AB is length and BC is width.
To find distance of AB and BC use formula,
[tex]Distance=\sqrt{(x2-x1)^2+(y2-y1)^2}[/tex]
[tex]AB=\sqrt{(12-\frac{7}{3} )^2+(\frac{15}{2}-\frac{15}{2} )^2} = \sqrt{(\frac{36-7}{3} )^2} =\frac{29}{3}= 9.67[/tex][tex]Bc=\sqrt{(12-12 )^2+(1-\frac{15}{2} )^2} = \sqrt{(\frac{2-15}{2} )^2} =\sqrt{(\frac{-13}{2})^2} = 6.5[/tex]
To find perimeter of rectangular dog run use formula,
[tex]Perimeter =2(Length + Width)\\\\Perimeter =2(AB+BC)\\\\Perimeter =2(9.67+6.5)\\\\Perimeter=2(16.17)\\\\Perimeter=32.34[/tex]
Hence, perimeter of rectangular dog run is 32.34 units.

A recording company obtains the blank cds used to produce its labels from three compact disk manufacturers: i, ii, and iii. The quality control department of the company has determined that 3% of the compact disks produced by manufacturer i are defective, 4% of those produced by manufacturer ii are defective, and 2% of those produced by manufacturer iii are defective. Manufacturers i, ii, and iii supply 36%, 52%, and 12%, respectively, of the compact disks used by the company. What is the probability that a randomly selected label produced by the company will contain a defective compact disk?.
The probability that a randomly selected label produced by the company will contain a defective compact disk is 0.034.
How to calculate the probability?In this, it should be noted that there are 3 possible cases in the chosen disc can be from any of the manufacturing companies, so the total probability will be the sum of probabilities of getting a faulty disc from companies 1-3.
The probability from company 1 will be;
= 0.03*0.36
The probability from company 2 will be:
= 0.04*0.52
The probability from company 3 will be:
= 0.02*0.12
The total probability will now be:= (0.36*0.03)+(0.04*0.52)+(0.02*0.12)
= 0.0108 + 0.0208 + 0.0024

The percent increase on the price of the home is 20.37%.
What is percent increase?
A percent increase refers to how much a percentage has gone up over time. In order to reach this number, you would need to find the difference between the original value and the final value, subtracting to find the exact total of the decrease.
Formula is given by
New number (value) – original number (value) = increase
Increase / original number (value) x 100 = percent increase
Given ,
initial value of home = $265,000
After few years, the value = $319,000
Increase = $319,000 - 265,000

Given, Cards are 65p each and gift wrap sheets are 45p each at a gift shop.
Owen buys 21 items from the shop and spends £11.85.
Let the number of cards be x,
the number of gift wrap sheets be y
Now, according to question
x + y = 21
0.65x + 0.45y = 11.85
On multiplying the first equation by 0.45, we get
0.45x + 0.45y = 9.45
0.65x + 0.45y = 11.85
On subtracting, we get
0.2x = 2.4
x = 12
