Suppose you buy a piece of office equipment for $17,000. After 3 years you sell it for a scrap value of $3,000. The equipment is depreciated linearly over 3 years. The rate of depreciation of the piece of equipment is

Answers

Depreciation amount = Purchase Price - Scrape Value
Depreciation amount = $17,000 - $3,000
Depreciation amount = $14,000

depreciation rate = $14,000/3 years
depreciation rate= $4667.67

The rate of depreciation of the piece of equipment is 27.45%.

Given that,

The cost of office equipment is $17,000.The number of years is 3And, the scrap value is $3,000.

Based on the above information, the depreciation should be

= (Office equipment cost - scrap value) ÷ (Office equipment cost × number of years)

= ($17,000 - $3,000) ÷ ($17,000 × 3)

= $14,000 ÷ $51,000

= 27.45%

Therefore we can conclude that the rate of depreciation of the piece of equipment is 27.45%.

In this situation what is the total tuition for taking MATH 080 the allowed four times

Answers

2nd attempt carries a price of 6% extra, so (6/100) * 548 is 32.88, so 548 + 32.88, the price is 580.88.

for the 3rd attempt 6% extra of that, (6/100) * 580.88, is 34.8528, so the price is 615.7328.

4th attempt is 6% extra of that, (6/100) * 615.7328, 36.943968, adding that will give us 652.676768.

Which of the numbers below correctly describes 5,000 µf?

Answers

Final answer:

The number 5,000 µF represents a capacitance, indicating that the capacitor can store 5,000 microcoulombs of electric charge at an electric potential difference of 1 volt.

Explanation:

The number 5,000 µF describes a capacitance. Capacitance is a measure of a capacitor's ability to store an electric charge. It can be defined as the ratio of the change in an electric charge in a system to the corresponding change in its electric potential. So, when we say a capacitor has a capacitance of 5,000 µF (microfarads), it means the capacitor can store 5,000 micro coulombs of electric charge at an electric potential difference of 1 volt. It's important to know that the typical range of capacitors can vary from fractions of a picofarad (pF) to a milifarad (mF).

Which shows the correct simplification of product of powers?
1.) 78 · 7-4 = 78· (–4) = 7–32
2.)78 · 7–4 = 78 ÷ (–4) = 7–2
3.)78 · 7–4 = 78 + (–4) = 74
4.)78 · 7–4 = 78 - (–4) = 712

Answers

The power symbols are missing.

I can infere that the product intended to simplify is (7^8) * (7^-4)., because that permits you to use the rule of the product of powers with the same base.

That rule is that the product of two powers with the same base is the base raised to the sum of the powers is:

(A^m) * (A^n) = A^ (m+n)

=>(7^8) * (7^-4) = 7^ [8 + (- 4) ] = 7^ [8 - 4] = 7^4, which is the option 3 if the powers are placed correctly.

The answer choice which shows the correct simplification of product of powers is:

78 · 7–4 = 78 + (–4) = 74

What is Product of Powers?

This refers to the mathematical property which states that when there is a multiplication of two powers that have the same base, then there would be the addition of exponents.

From the given choices, we can see that the powers are not given, so we can solve using inference.

This posits that (7^8) * (7^-4) was the product that was intended to be simplified and this law shows:

(A^m) * (A^n) = A^ (m+n)

Hence, if we add the powers, then the correct answer would be option C because they are of the same base.

Graph the line y+3=2(x-1) first identify the slope of the line

Answers

First you need to simplify the equation.

y + 3 = 2(x - 1)
y + 3 = 2x - 2

Then you need to put that into slope-intercept form (y = (slope)x + (y intercept))

y + 3 = 2x - 2
-3 -3
y = 2x - 5

The slope is the coefficient of x, so 2 is the slope of the line.

A theater can seat 864 people. The number of rows is 5 less than the number of seats in each row. How many rows of seats are there?

Answers

There should be 27 rows of 32 seats.

Final answer:

To determine the number of rows in a theater that can seat 864 people, with the number of rows being 5 less than the number of seats per row, we set up the equation x(x-5)=864. Solving this quadratic equation, we find that there are 31 rows of seats.

Explanation:

To solve for the number of rows in the theater, let's denote the number of seats in each row as x and the number of rows as x - 5. Since the product of the number of seats in each row and the number of rows will give us the total seating capacity, we can write down the equation:

x(x - 5) = 864

Expanding the equation, we get:

x2 - 5x - 864 = 0

Using the quadratic formula or factoring, we find that x = 36. Therefore:

The number of rows is x - 5 = 36 - 5 = 31.

So, the theater has 31 rows of seats.

Answers

35/10 = 7/5

the last equation is false so the first equation is false. The original two ratios are NOT proportional

Another way to see this is to use a calculator to get the decimal form of each fraction

b. x ≡ 2 (mod 3), x ≡ 3 (mod 4), x ≡ 1 (mod 5).

Answers

(a) Suppose we let

[tex]x=2+4=6[/tex]

Modulo 7, we're left with [tex]x\equiv2+4\pmod7=6\mod7[/tex], but we want a remainder of 2, so multiply 4 by 7 to assure that that remainder vanishes. So now

[tex]x=2+4\cdot7=30[/tex]

and [tex]x\equiv2\pmod7[/tex], but modulo 11, we have [tex]x=\equiv2+28\equiv2+4\equiv6\pmod{11}[/tex]. But we want the remainder to be 4, so multiply the first term by 11 to guarantee this. So we write

[tex]x=2\cdot11+4\cdot7=50[/tex]

but now, we get a remainder of 1 modulo 7 and 6 modulo 11. To fix the first case, multiply the first term by 2. For the second case, first find the inverse of 6 modulo 11. We have [tex]2\cdot6=12[/tex], and [tex]12\equiv1\pmod{11}[/tex], so the inverse is 2. Multiply the second term by 2, so that the second term's remainder modulo 11 becomes 1. Then multiply by 4, so that now

[tex]x=2\cdot11\cdot2+4\cdot7\cdot2\cdot4=268[/tex]

We have

[tex]x=268=3\cdot77+37\implies x\equiv37\pmod{77}[/tex]

(b) This is done similarly. Modulo 3, we want a remainder of 2, so we can start with

[tex]x=2+3+3=8[/tex]

Then taken modulo 4, we need to multiply the first term by 2 and the third term by 4 to ensure the remainder becomes 3. The second term can be left alone.

[tex]x=2\cdot2+3+3\cdot4=19[/tex]

Now taken modulo 5, we can multiply the first two terms by 5 and the third term by the inverse of [tex]3\times2\equiv12\equiv2\pmod5[/tex]. We have [tex]3\cdot2\equiv6\equiv1\pmod5[/tex], so we multiply by 3.

[tex]x=2\cdot2\cdot5+3\cdot5+3\cdot4\cdot3=71[/tex]

Now

[tex]x=71=1\cdot(3\cdot4\cdot5)+11=1\cdot60+11[/tex]

which means the smallest positive solution for the system would be [tex]x=11[/tex].

a pump is running at 6.4 quarts per minute. how many gallons per hour is this?

Answers

60*6.4 quarts = 384 quarts = 96 Gallons/hr

A gas station operates two pumps, each of which can pump up to 10,000 gallons of gas in a month. the total of gas pumped at the station in a month is a random variable y (measured in 10,000 gallons) with a probability density function (p.d.f.) given by compute e(y)

Answers

Given that a gas station operates two pumps, each of which can pump up to 10,000 gallons of gas in a month and that the total of gas pumped at the station in a month is a random variable y (measured in 10,000 gallons) with a probability density function (p.d.f.) given by

[tex]f(y)=\begin{cases} cy, & \text{if} \ \ 0\ \textless \ y\ \textless \ 1 \\ (2-y), & \text{if} \ \ 1\leq y\ \textless \ 2 \\ 0, & \text{elsewhere} \end{cases}[/tex]

Part A:

The value of c that makes f(y) a pdf is obtained as follows:

[tex]F(\infty)= \int\limits^{\infty}_{-\infty} {f(y)} \, dy=1 \\ \\ \Rightarrow \int\limits^1_0 {cy} \, dy +\int\limits^2_1 {(2-y)} \, dy=1 \\ \\ \Rightarrow \left. \frac{cy^2}{2} \right]^1_0+\left[2y- \frac{y^2}{2} \right]^2_1=1 \\ \\ \Rightarrow \frac{c}{2} +4-2-2+ \frac{1}{2} =1 \\ \\ \Rightarrow \frac{c}{2} = \frac{1}{2} \\ \\ \Rightarrow \bold{c=1} [/tex]

Part B:

We compute E(y) as follows:

[tex]E(y)=\int\limits^{\infty}_{-\infty} {yf(y)} \, dy \\ \\ =\int\limits^1_0 {y^2} \, dy +\int\limits^2_1 {(2y-y^2)} \, dy \\ \\ =\left. \frac{y^3}{3} \right]^1_0+\left[y^2- \frac{y^3}{3} \right]^2_1 \\ \\ = \frac{1}{3} +4- \frac{8}{3} -1+ \frac{1}{3} \\ \\ =1[/tex]

Therefore, E(y) = 1.

Final answer:

The expected value E(y) cannot be computed without the given probability density function for the random variable y. The computation involves integrating the product of the variable and its probability density over its range. An example has been provided for how to compute the expected value with a hypothetical p.d.f.

Explanation:

To answer the student's question, it appears there may be a missing probability density function (p.d.f.) for the random variable y, which represents the total amount of gas pumped at the station in a month. Without the actual function, we cannot compute E(y), which is the expected value (mean) of the random variable y. In general, if we had the p.d.f., we would compute the expected value by integrating the product of the variable and its probability density over its range.

An example of how to compute the expected value if we had a p.d.f. f(y) might look like this:

E(y) = ∫ y × f(y) dy

For instance, if the p.d.f. were f(y) = ay (a being a constant) over the interval [0, 1], then:

Integrate the product of y and the p.d.f. over the interval:E(y) = ∫01 y × ay dy = a × ∫01 y² dyAfter computing the integral you would find the expected value E(y).

However, without the p.d.f. provided, we can only state the method, not the actual expected value.
