The length of a rectangle in longer than it’s width. If the perimeter of the rectangle is 70 in, find the length and width.
When the perimeter of the rectangle is 70 in, the length and width are 19 and 16 inches.
How to calculate the length?It should be noted that the perimeter of a rectangle will be calculated as:
= 2(Length + Width)
In this case, the length of a rectangle is 3in longer than it’s width and the perimeter of the rectangle is 70 in.
Therefore, width = w
length = w + 3
The perimeter will be:
2(w + w + 3) = 70
2(2w + 3) = 70
4w + 6 = 70
Collect like terms
4w = 70 - 6
4w = 64
Divide
w = 64 / 4
w = 16
Width = 16 inches
Length = w + 3 = 16 + 3 = 19 inches.

Ruben bought 6 new books for his collection. This increased his collection by 12% How many books did he have before this purchase? Please explain
Answer:
Ruben had 50 booksStep-by-step explanation:
Let the initial number of books be x.
Set equation:
x + 6 = x + 12%x + 6 = x + 0.12x0.12x = 6x = 6/0.12x = 50Answer:
50 books
Step-by-step explanation:
Forming the equation,
→ x + ((x/100) × 12) = x + 6
Now the value of x will be,
→ x + ((x/100) × 12) = x + 6
→ x - x + (12x/100) = 6
→ 0.12x = 6
→ x = 6/0.12
→ [ x = 50 books ]
Hence, answer is 50 books.

Given the properties, write a quadratic function for:
f(3+sqrt(2))=f(3-sqrt(2))=0
if f(1)=-8
Quadratic function for the given properties is [tex]y=-4x^{2} +24x-28[/tex].
The roots are [tex]3+\sqrt{2}[/tex] and [tex]3-\sqrt{2}[/tex]; that means the axis of symmetry is x=3; which means the vertex has x coordinate 3. Then the vertex form of the equation is
[tex]y = a(x-3)^{2}+k[/tex]
Then since y is 0 when x is [tex]3+\sqrt{2}[/tex],
[tex]0=a(\sqrt{2} )^{2} +k[/tex]
[tex]0=2a+k[/tex] (1)
And when x = 1, y = -8,
[tex]-8 = a(-2)^{2}+k[/tex]
[tex]-8=4a+k[/tex] (2)
Then from equations (1) and (2)
[tex]-8=2a[/tex]
[tex]a = -4[/tex]
And then from either equation (1) or (2), k = 8.
So the equation is
[tex]y = -4(x-3)^{2}+8[/tex]
[tex]y=-4(x^{2} -6x+9)+8[/tex]
[tex]y=-4x^{2} +24x-28[/tex]

The mass of the solid copper is 1479 g.
According to the question,
We have the following information:

are yellow, 10 are green, 14% are
orange and the rest are blue.
What percentage of the skittles are
blue?
Answer: 26%
Step-by-step explanation: 50 x 0.14 = 7. 12 + 8 + 10 + 7 = 37, 37÷50=0.26 so 26%
The percentage of blue skittles is 26%.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Total number of skittles = 50
Red skittles = 12
Yellow skittles = 8
Green skittles = 10
Orange skittles = 14%
This means,
= 14/100 x 50
= 7
Blue skittles.
= 50 - (12 + 8 + 10 + 7)
= 50 - 37
= 13
The percentage of blue skittles.

Yes, quadrilateral ABCD is a parallelogram.
What are the properties of parallelogram?
A parallelogram is a particular sort of polygon. It is a quadrilateral in which the opposite side pairs are parallel to one another.
Properties:
1. Opposite sides are congruent.
2. Opposite angels are congruent.
3. Consecutive angles are supplementary.
4. If one angle is right, then all angles are right.
5. The diagonals of a parallelogram bisect each other.
6. Each diagonal of a parallelogram separates it into two congruent
It is given that the coordinates of the vertices of quadrilateral ABCD are A (8, -3), B(-2, 1), C (-4,-4), and D(6, -8).
According to distance formula,
If A(a,b) and B(x,y) are two coordinates then
AB = [tex]\sqrt{(x-a)^{2}+(y-b)^{2}}[/tex]
Now, using this distance formula in quadrilateral ABCD
AB = [tex]\sqrt{(-2-8)^{2}+(1+3)^{2}}= \sqrt{(-10)^{2}+(4)^{2}}=\sqrt{100+16}=\sqrt{116}[/tex]
CD = [tex]\sqrt{(6+4)^{2}+(-8+4)^{2}}=\sqrt{10^2+(-4)^2}=\sqrt{100+16}=\sqrt{116}[/tex]
Now, If we have two coordinates A(a,b) and B(x,y) then
Slope of AB = [tex]\frac{y-b}{x-a}[/tex]
Using this formula , finding slope of AB and CD of quadrilateral ABCD we get ,
Slope of AB = [tex]\frac{1+3}{-2-8}=\frac{4}{-10}=\frac{2}{-5}[/tex]
Slope of CD = [tex]\frac{-8+4}{6+4}=\frac{-4}{10}=\frac{-2}{5}[/tex]
As slope of both AB and CD is equal therefore, we can say that AB and CD are parallel.
As AB = CD and AB is parallel to Cd Therefore, ABCD is a parallelogram as opposite sides of parallelogram are equal and parallel.
Hence, quadrilateral ABCD is a parallelogram.

What is Percentage ??A percentage is a figure or a ratio that is expressed as a fraction of 100. The percentage sign, "%," is used to denote it. The percentage is denoted by the abbreviations "pct" or "pc." In other words, the percentage is measured in terms of 100 and is defined as the proportion of one quantity that is made up of another.
The % has no boundaries. It implies that they are dimensionless numbers. When we state a number is 60% of something, we are implying that it is 60% of everything. Even fractional versions, like 0.56% or 0.87%, can be used to express it. Students' exam scores in any subject are calculated as a percentage. For instance, Pooja received a 78% on his exam.
Tax slab is as follows:-
0 - 10,000 = 3%
10,001 - 50,000 = 5%
50,001 - 100,000 = 5.5%
So total salary = $60000
Till $10000 tax deduction will be 3%
So, $10000 * 0.03 = $300
Then from $10,001 - $50,000 tax deduction will be 5%
Hence, the tax deduction will be $40000 * 0.05 = $2000
And from $50,001 - $100,000 tax deduction will be 5.5%
Only $10000 will be available for tax deduction
so, $10000 * 0.055 = 550

⇒As a results you can see above we have an equation that can enable us to solve for x.
⇒Solving for x we have
[tex]4x+3x+5x+3-2+103+100=540\\[/tex]
⇒Now let us simplify like terms since we have grouped them already.
[tex]12x+204=540\\12x=540-204\\12x=336\\\frac{12x}{12} =\frac{336}{12} \\x=28[/tex]
∴ x=28°
Note I have written the equation above, as the first step.
