Rewrite 0.580 80 repeating decimal
Step-by-step explanation:
first off, we'll move the non-repeating part in the decimal to the left-side, by doing a division by a power of 10.
then we'll equate the value to some variable, and move the repeating part over to the left as well.
anyhow, the idea being, we can just use that variable, say "x" for the repeating bit, let's proceed,
\begin{gathered}\bf 0.580\overline{80}\implies \boxed{\cfrac{5.80\overline{80}}{10}}\qquad \textit{now, let's say }x= 5.80\overline{80}\\\\ -------------------------------\end{gathered}
0.580
80
⟹
10
5.80
80
now, let’s say x=5.80
80
−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−
\begin{gathered}\bf thus\qquad \begin{array}{llll} 100\cdot x&=&580.80\overline{80}\\ &&575+5.80\overline{80}\\ &&575+x \end{array}\qquad \implies 100x=575+x \\\\\\ 99x=575\implies x=\cfrac{575}{99}\qquad therefore\qquad \boxed{\cfrac{5.80\overline{80}}{10}}\implies \cfrac{\quad \frac{575}{99}\quad }{10} \\\\\\ \cfrac{\quad \frac{575}{99}\quad }{\frac{10}{1}}\implies \cfrac{575}{99}\cdot \cfrac{1}{10}\implies \cfrac{575}{990}\implies \stackrel{simplified}{\cfrac{115}{198}}\end{gathered}
thus
100⋅x
=
580.80
80
575+5.80
80
575+x
⟹100x=575+x
99x=575⟹x=
99
575
therefore
10
5.80

⟹
10

⟹

⟹

Because 80 is repeat and simply .80 = .8

The perimeter of a rectangle is 92 cm. If the length is 22 cm, how wide is the rectangle?
A) First write an equation you can use to answer this question. Use w as your variable in the equation.
Answer:
W = 24cm
Step-by-step explanation:
p of a rectangle = 92
L = 22cm and W = ?
p = 2(L+W)
92 = 2(22+W)
92 = 44 + 2W
2W = 92 - 44
2W = 48
W = 48/2
W = 24cm

If two functions are inverses of each other, which 2 statements are true?
A The graph of an inverse of a function is a reflection of the function across the line y=x. B f(g(x)) = x and g(f(x)) = x
C The graph of an inverse of a function is a reflection of the function across the line y=0. D f(g(x)) =1 and g(f(x)) = 1
Answer:
A and B
Step-by-step explanation:
To be inverses, the inverse composite functions must equal x, since the input and output must be equal as how much you used as your input, which is x. B proves that. Also, the graph must reflect over y = x, which is the line that runs through the origin

What is Simplification?Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are all referred to as PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.
Given, the values of a and b are 9/11 and 7/10 respectively
thus,
ab = 9/11 * 7/10
simplifying it
ab = 63/110
Therefore, the value of ab is 63/110 when a = 9/11 and b = 7/10

Step-by-step explanation:
h(t) = 3t2 + 4t
g(t) = t - 1
Find h(g(t))
3t2 - 2t - 1
4+3 - 12t + 1
3t2 + 4t - 1
3t2 - 4t - 1
Answer:
first we need to substitute g(t) value in h(t) value and then evaluate the expression as follows :
h(g(t))=3(t-1)²+4(t-1).
by solving
h(g(t))=3(t²+1-2t)+4t-4
h(g(t))=3t²-2t-1 will.be the final answer

To multiply numbers or expressions means that we calculate the product of the numbers or expressions. The value of [tex]-0.5 \times (-0.4)[/tex] is [tex]0.2[/tex]
Given that:
[tex]-0.5 \times (-0.4)[/tex]
Cancel out the negative signs

Gymnast Clothing manufactures expensive hockey jerseys for sale to college bookstores in runs of up to 150. Its cost (in dollars) for a run of x hockey jerseys is
C(x) = 1500 + 10x + 0.2x2 (0 ≤ x ≤ 150)
1. Gymnast Clothing sells the jerseys at $90 each. Find the revenue function.
2. Find the profit function.
3. How many should Gymnast Clothing manufacture to make a profit?
The Revenue function for the number of jerseys x sold is ; R(x) = 90x
The profit function from the sale of x jerseys is ; P(x) = - 0.2x² + 80x - 1500
The number of Jerseys to manufacture in other to make profit = 20
The revenue made is the total amount made from the sale of the hickey jerseys :
Sales price per jersey = $90
Hence, the revenue made, R(x) = 90x
The Cost function, C(x) = C(x) = 1500 + 10x + 0.2x²
Recall :
Profit = Revenue - Cost
Hence,
P(x) = R(x) - C(x)
P(x) = 90 - (0.2x² + 10x + 1500)
P(x) = 90 - 0.2x² - 10x - 1500
P(x) = - 0.2x² + 80x - 1500
To make profit, equate P(x) to 0 ;
0.2x² - 80x + 1500 = 0
Using a quadratic calculator :
x = 380.22 or x = 19.72
Hence, to make a profit, the number of jerseys that must be sold is 20.

A business uses straight-line depreciation to determine the value y of a piece of machinery over a 10-year period. Suppose the original value (when t=0) is equal to $34,000 and its value is reduced by $3400 each year. Write the linear equation that models the value y of this machinery at the end of year t.
The linear equation that models the value y of this machinery at the end of year t is y = $34,000 - $3,400t
A linear equation is an algebraic equation in the form :
y = mx + b
where y = intercept
m = slope
x and y are variables
Depreciation is used in expensing the cost of the asset
The value of the asset reduces by $3400 every year
The equation is :
y = $34,000 - $3,400t
At the end of one year, y = $34,000 - $3,400(1) = $30,600
At the end of two years, y = $34,000 - $3,400(2) = $27,200
At the end of ten years, y = $34,000 - $3,400(10) = 0
