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

The time passed between 8:15 to 2:30 is 6 hours 15 minutes.

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= 9/11 and b=7/10

now,

ab = (9/11)×(7/10)

=63/110.......

the value of ab is 63/110 when a = 9/11 and b = 7/10

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

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

Answer:

51.3%

Step-by-step explanation:

You must divide 100 by 195. In order to find the equivalent ratio you must multiply the number you are dividing by, by 100. So it will become 100/195.

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
