Answer:
Rate of depreciation = 27%
Step-by-step explanation:
Given:
Purchase price = $32,650
Rate in 2020 = $23,834.50
Find:
Rate of depreciation
Computation:
Depreciation = Purchase price - Rate in 2020
Depreciation = $32,650 - 23,834.50
Depreciation = $8,815.5
Rate of depreciation = [8,815.5 / 32650] 100
Rate of depreciation = 27%

3. What is the Kinetic Energy of a 100 kg object that is moving with a speed of 12.5 m/s?
Answer:
7812.5 J
Step-by-step explanation:
Kinetic energy is equal to 1/2 m v^2.
The mass of the object is 100 and the velocity is 12.5 m/s.
Therefore, the kinetic energy is 1/2 (100) (12.5)^2 = 7812.5 J.
Answer:
KE = ½ (100kg) (12.5 m/s)2
KE = ½ (100kg)(156.25)
KE = 7,812.5J
answer ^
Step-by-step explanation:
KE = ½ mv2
KE = ?
m = 100kg
v = 12.5m/s
The average natural gas bill for a random sample of 26 homes in the 19808 zip code during the month of March was $305.30 with a sample standard deviation of $46.50. The critical value for a 95% confidence interval around this sample mean is ________.
Answer:
2.06
Step-by-step explanation:
The formula for critical value = Margin of Error / Standard Error
Margin of Error = z × Standard deviation/√n
Mean for the month of March = $305.30
Standard deviation = $46.50
n = number of samples = 26 homes
z score for 95% confidence interval = 1.96
= 1.96 × $46.50/√26
= 17.874024556
Standard error = standard deviation/√n
= $46.50/√26
= 9.1194002839
Critical value = Margin of Error/Standard Error
= 17.874024556/9.1194002839
= 2.06

Round 8,503 to nearest thousand
Answer:
9,000
Step-by-step explanation:
If x < 5, we round down.
If x ≥ 5, we round up.
Since 8,503, 500 is ≥ 5, we round up to 9. So,
8,503 ≈ 9,000
Answer:
9,000
Step-by-step explanation:
Look to the hundreds place. If the number is 4 or below we round down. If the number is 5 or above we round up.The number is 5, so we round up. The 8 in the thousands place becomes a 9, and the other places become 0s. Write out the newly rounded number: 9,000You're done! I hope this helps!
What is the product of the polynomials below?
(7x2+2x+4)(2x+5)
Answer:
This is a simple multiplication problem.
Here is my steps:
(14x^3 + 35x^2 + 4x + 10x + 8x + 20)
Combine like terms:
(14x^3 + 35x^2 + 22x + 20)
And that is your answer^^
Answer:
14x3+ 39x2 +8x +20
Step-by-step explanation:
Use the distributive property and/or the FOIL (front, outer, inner, last) method.
First:
Multiply (7x2)(2x)
=14x3
Then (7x) (5)
=35x2
Second:
Multiply (2x)(2x)
=4x2
Then (2x)(5)
=10
Third:
Multiply 4(2x)
=8x
Then (4)(5)
=20
You should get:
14x3 +35x2 +4x2 +10 +8x +10
Add all common numbers.
You should get:
14x3+ 39x2 +8x +20

The integer closet to -7π is -22.
What is integer?An integer is a number that includes both negative and positive numbers, including zero, and does not have a decimal or fractional component. Examples of integers include: -5, 0, 1, 5, 8, 97, and 3,043. Z is a set of integers that includes the following:
Positive figures: If a number is greater than zero, it is positive. Example: 1, 2, 3 . . .
Negative Counts: If a number is less than zero, it is negative. Example: -1, -2, -3 . . .
Zero cannot be thought of as either a negative or a positive number. It's a complete number.
Given -7π
the value of π in fraction form is 22/7
substitute the value of π
-7π = -7 x 22/7
-7π = -22
Hence, -22 is integer is closest to −7π.

The question is incomplete.
The complete question is:
Determine if the function is a polynomial function. If the function is a polynomial function, state the degree and the leading coefficient. If the function is not a
polynomial, state why.
F(x) = 1,050
A. This is a polynomial function of degree zero with a leading coefficient of 1,050.B. This is not a polynomial. Horizontal lines can not be polynomials as there are no turning points.C. This is not a polynomial. Only vertical lines of the form x = b can be classified as a polynomial.D. This is not a polynomial because there are no variables.We have a function:
f(x) = 1050
We can write it as:
f(x) = 1050x⁰
x⁰ = 1
As we know from the definition of the polynomial:
The polynomial is a combination of the variable and constant with powers of x that are non-negative.
f(x) = 1050 is a polynomial function of degree zero with a leading coefficient of 1,050.
Thus, the function f(x) = 1050 is a polynomial with degree zero option (A) this is a polynomial function of degree zero with a leading coefficient of 1,050 is correct.

Answer:
Segment bisector: JK
MN= 52
Step-by-step explanation:
The segment bisector basically means the point where the line is cut in half. If you study the figure, you can see the two small red lines intersecting The longer line. This means that the two small black segments are equal to each other. With this in mind, we now know that the segment bisector is line JK.
To find the length of MN, study the figure again. You can see that we are given the value of one line segment that is half the length of MN. So all we need to do is multiply that value by 2:
[tex]26*2=52[/tex]
The length of line segment MN is 52.
:Done
Answer:
MN = 52
Step-by-step explanation:
bisector is just a half of its length
looking through the graph
MN = 26 * 2 (just multiply ot by 2)
MN = 52

You will use minus sign for the equation in other to eliminate one of the letters and use the other one to find the one eliminated later...Which means that 4x+y=5 (-) 3x+y=8..... the minus sign will eliminate +y and +y in each equation because the "+y" in the second equation will be turned to -y because + times(×) - will give us minus sign so the "y" will be eliminated to give space for the 'x" .After the x has been found which is x=-3 then you will substitute x=-3 into the any equation and then you will also find the "y" which is y=17.....Thank you
Solve the equation x+2/3=18
Answer: x=52/3
Step-by-step explanation:
x+2/3=18
x=18-2/3 ⇔ subtraction property of equality
x=54/3-2/3 ⇔ convert integer into fraction
x=52/3
Hope this helps!! :)
Answer:
see below
Step-by-step explanation:
( x+2)/3=18
Multiply each side by 3
(x+2)/3 *3 = 18*3
x+2 = 54
Subtract 2
x+2-2 =54-2
x = 52
or if
x+2/3=18
Subtract 2/3
x+2/3 -2/3 = 18-2/3
x = 17 +1 -2/3
x = 17 1/3

On March 24, 1989, the Exxon Valdez oil tanker ran aground and leaked millions of gallons of oil into Prince William Sound. The spill covered approximately 11,000 square miles of ocean. The oil spread out in a circular pattern and the radius increased by 0.10 mph. Use π = 3.14. At this rate, how many hours did it take for oil to cover the area?
Answer:
592 hours
Step-by-step explanation:
Given
[tex]Area = 11000m^2[/tex]
[tex]Radius = 0.10m/h[/tex]
Required
Determine the time taken to cover the area
Since, the oil formed a circular pattern; the question will be answered using area of a circle
[tex]Area = \pi r^2[/tex]
Let t represent the time take to cover 11000m²;
The relationship between these parameters is:
[tex]11000 = \pi * (0.10t)^2[/tex]
Substitute 3.14 for π
[tex]11000 = 3.14 * (0.10t)^2[/tex]
Divide both sides by 3.14
[tex]\frac{11000}{3.14} = \frac{3.14 * (0.10t)^2}{3.14}[/tex]
[tex]\frac{11000}{3.14} =(0.10t)^2[/tex]
[tex]3503.18471338 = (0.10t)^2[/tex]
Take square root of both sides
[tex]\sqrt{3503.18471338} = \sqrt{(0.10t)^2}[/tex]
[tex]\sqrt{3503.18471338} = 0.10t[/tex]
[tex]59.1877074516 = 0.10t[/tex]
Divide both sides by 0.10
[tex]\frac{59.1877074516}{0.10} = \frac{0.10t}{0.10}[/tex]
[tex]\frac{59.1877074516}{0.10} = t[/tex]
[tex]591.877074516 = t[/tex]
[tex]t = 591.877074516[/tex]
[tex]t = 592\ hours[/tex] (Approximated)
Hence, it'll take approximately 592 hours to cover the given area

The edge length of a cube with volume 24 cubic units
Answer:
2∛3 units
Step-by-step explanation:
The volume is the cube of the edge length, so the edge length is the cube root of the volume:
s = ∛V
s = ∛24 = ∛(2³·3)
s = 2∛3
The edge length is 2∛3 ≈ 2.8845 units.

We started with five gallons of an orange drink that was 90% water and 10% syrup. We added 1 gallon of concentrate and ended up with a resulting mixture that was 86% water and 14% syrup. Determine what percent of the concentrate was water and what percent was syrup.
Answer:
The gallon of concentrate was 66% water and 34% syrup.
Step-by-step explanation:
- The first thing is to know how much water and how much syrup have the 5 gallons.
90% water and 10% syrup.
- If we have 5 gallons with the same percentages then:
Where X is the percentage that we do not know.
(90 + 90 + 90+ 90 + 90 + X) / 6 = 86
(90 + 90 + 90+ 90 + 90 + X) = 516
X = 66
The answer is 66% water in the gallon added.
