Based on the rate of depreciation each year, the amount of depreciation of the machinery in the sixth year will be $300.
What is the annual depreciation amount?The depreciation in the second year is:
= 6,000 - 5,700
= $300
The depreciation in the third year is:
= 5,700 - 5,400
= $300
If this amount remains constant till the sixth year therefore, then it means that the sixth year depreciation amount is also $300.

6. What is the solution to the equation 2/3x + 1 = 1/6x - 7? *
X = -16
x = -4
x = 4
X = 16
Answer:
x=-16
Step-by-step explanation:
2/3x+1=1/6x-7.
Subtract 1/6x.
1/2x+1=-7
subtract 1.
1/2x=-8
divide by 1/2.
x=-16.
Hope this helps plz hit the crown :D
Step-by-step explanation:
[tex] \frac{2}{3} x + 1 = \frac{1}{6}x - 7 \\ \frac{4}{6} x - \frac{1}{6} x = - 7 - 1 \\ \frac{3}{6} x = - 8 \\ \frac{1}{2} x = - 8 \\ \boxed{ x = - 16}[/tex]

How do i get the answer x= 3, -1 for equation (3/x^2)+ 2/x =1
Answer:
Steps below
Step-by-step explanation:
(3/x²)+ 2/x =1 (x ≠ 0)
(3/x²) + 2x/x² = 1
(3 + 2x) / x² = 1
3 + 2x = x²
x² - 2x - 3 = 0
(x + 1) (x - 3) =0
x = -1 or x = 3
Explain why it makes sense that a system of two lines with equal slopes but different y-intercepts has no solutions.
Answer:
Please check explanations
Step-by-step explanation:
Here, we want to seek why the system has no solutions
An example is necessary
Let us have two lines with equal slopes and different y-intercepts
y = 2x + 5
y = 2x - 3
To solve this system, we equate the y-values
2x + 5 = 2x - 3
The reason why this has no solution is that there is no x value that would validate the equality
It is impossible to find an x value which when inserted would make both equations equal
In the absence of this, we can make that conclusion that the system of equations has no solution

Explain how the net of rectangular prism can help you find the surface area or the prism?
A 3d cardboard box has 6 sides, each of which are rectangles. If you unfold the 3D box, and flatten it out, then you'll be left with 6 rectangles such as what you see in the attachment below. This is one way to unfold the box. This flattened drawing is the net of the 3D rectangular prism. You can think of it as wrapping paper that covers the exterior of the box. There are no gaps or overlapping portions. If you can find the area of each piece of the net, and add up those pieces, that gets you the total area of the net. This is the exactly the surface area of the box.
In the drawing below, I've marked the sides as: top, bottom, left, right, front, back. This way you can see how the 3D box unfolds and how the sides correspond to one another. Other net configurations are possible.
The perimeter of a triangle is 34 feet. One side of the triangle is 2 times the second side. The third side is 2 feet longer than the second side. Find the length of each side
Answer:
6.4 feet
12.8 feet
14.8 feet
Step-by-step explanation:
let x = length of 1st side
let 2x = length of 2nd side
let 2x + 2 = length of 3rd side
add them all together and set sum equal to 34
x + 2x + 2x + 2 = 34
5x + 2 = 34
5x = 32
x = 6.4, which is 1st side
2x = 12.8, which is 2nd side
2x + 2 = 14.8, which is 3rd side

Lucy and JoJo need to make 140 cupcakes for the school dance. Lucy made 35 of the cupcakes JoJo made 42 cupcakes What fraction of the cupcakes do Lucy and JoJo still need to make? (Use / as a fraction bar.)
Answer:
16/35
Step-by-step explanation:
From the question we are given:
total number of cupcakes needed for the school dance = 140 cupcakes
Lucy made 35cupckes
JoJo made 42 cupcakes
Total cupcakes made by JoJo and Lucy = 35+42 = 76cupcakes
Remaining cupcakes still needed to be made = 140 - 76 = 64cupckes
Fraction of the cupcakes that Lucy and JoJo still need to make = 64/140
Fraction of the cupcakes that Lucy and JoJo still need to make = 16/35
Hence the fraction of the cupcakes that Lucy and JoJo still need to make is 16/35

Answer:We have,
Beans sold in 1 hour = 10 pounds
So, Beans sold in 3 hours = 30 pounds
Decrease in green beans after 3 hours is 30 pounds.
Now,
Step-by-step explanation:
Answer:
18,75%
Step-by-step explanation:
3 x 10 = 30
so, she sold 30 pounds in 3 hours
160/100=1.6
1% - 1.6 pounds
30/1.6=18,75

= 5×2^n. .......... 1
Where n is 4 which can as well range from ( 1,2,3,4 )
Hence, using the expression in equation 1
Ist minute where n = 1
5(2^1) = 10 butterflies
2nd minutes: where n = 2
5(2)(2) = 5(2^2) butterflies
After 3rd minutes :
5(2^3) butterflies where n = 3
After 4th minutes : where n = 4
5(2^4) butterflies
But at that point she was able to capture 4.
After 4 min, number on screen = 5(2^4) - 4
= 5(16) - 4
= 80-4
= 76
The energy that generates wind comes from what source A. Soar radiation B. Magnetic attraction C. Moon's gravity D. Coriolis effect
Answer:
A. Soar radiation
Step-by-step explanation:
Blowing wind rotates the wind turbine and generates the energy called wind energy. More the speed of wind, more the energy can be generated.
That's how, wind energy depends on the speed of the wind and the speed of the wind is due to the pressure difference in various regions.
The zone having more solar radiation has low pressure and the zone having less solar radiation have high pressure of air and winds flows from high to low-pressure zone.
Therefore, the energy that generates wind comes from what source soar radiation.
Hence, option (A) is correct.

d is proportional to S^2
d=900 when s=20
calculate the value of D when S=25
Answer:
d = 1406.25
Step-by-step explanation:
Given d is proportional to s² then the equation relating them is
d = ks² ← k is the constant of proportion
To find k use the condition d = 900 when s = 20
900 = k × 20² = 400k ( divide both sides by 400 )
2.25 = k
d = 2.25s² ← equation of proportion
When s = 25, then
d = 2.25 × 25² = 2.25 × 625 = 1406.25
The Lopez family is traveling from the beach to their house at a average speed of 65 miles per hour. At noon, they have driven 50 miles. Which equation represents the total distance they have driven, d, in terms of the number of hours since noon, h?
The equation that represents the total distance they have driven, d, in terms of the number of hours since noon, h is:
d = 65h + 50
Which equation represents the total distance that the family has traveled?The equation that represents the total distance that the family traveled must show the initial distance they started with, the velocity at which they are traveling and the time they have covered.
The initial distance that they started with is = 50 miles
The velocity at which they are traveling is 65miles/hr
Therefore the total distance they have driven, d, in terms of the number of hours since noon, h
= 65h + 50
Therefore, the third option is correct.
