63%
First, we have to take 20.00 - 7.40 which gets us 12.60.
Then, we use the formula where we put the 12.60 on top of a fraction bar, and the 20.00 on bottom.
We do 12.60 x 100 which makes 1260.
Lastly, we divide that by the 20.00 which gets us 63.

Equipment was acquired at the beginning of the year at a cost of $36,000. The equipment was depreciated using the double-declining-balance method based on an estimated useful life of ten years and an estimated residual value of $700.
Question Content Area
a. What was the depreciation for the first year?
fill in the blank
b. Assuming the equipment was sold at the end of year 2 for $8,860, determine the gain or loss on the sale of the equipment.
fill in the blank
The depreciation for the first year is $28,800.
If the equipment is sold for $8,860 at the end of year 2, the loss on the sale is $-14,180.
What is the depreciation in year 1 and the loss on the sale?
Depreciation is the method used in expensing the cost of an asset. The double declining method is an exponential method that is used to expense the cost of an asset.
Depreciation expense using the double declining method = Depreciation factor x cost of the asset
Depreciation factor for the double declining method = 2 x (1/useful life)
Depreciation expense in year 1 = (2 / 10) x $36,000 = $7,200
Book value at the beginning of year 2 = cost of the asset - depreciation in year 1
$36,000 - $7,200 = $28,800
Depreciation in year 2 = (2/10) x $28,800 = $5,760
Book value at the end of year 2 = book value at the end of year 1 - depreciation in year 2
$28,800 - $5,760 = $23,040
Loss = sales price - cost price
Loss = $8,860 - $23,040 = $-14,180

A medical equipment industry manufactures X-ray machines. The unit cost C (the cost in dollars to make each X-ray machine) depends on the number of
machines made. If .x machines are made, then the unit cost is given by the function C (x)=0.5x²-320x+68,684. What is the minimum unit cost?
Do not round your answer.
According to the concept of quadratic equation, the minimum cost for the x ray machine is $17, 484
Quadratic equation:
Basically, the polynomial equation with highest degree of two is called a quadratic equation.
The general equation is given by ax² + bx + c = 0, where a ≠ 0.
Given,
A medical equipment industry manufactures X-ray machines. The unit cost C (the cost in dollars to make each X-ray machine) depends on the number of machines made. If .x machines are made, then the unit cost is given by the function C (x)=0.5x²-320x+68,684.
Here we need to find the minimum unit cost.
Here we know that the standard form of a quadratic is given by:
=> ax² + bx + c
From this function, we have to calculate the value of x as,
=> x = -b/ 2a
While we compare the standard form with the given function,
=> C (x)=0.5x²-320x+68,684.
Then we get the value of
=> a = 0.5
=> b = -320
=> c = 68,684
So, the value of x is calculated as,
=> x = -(-320) / 2(0.5)
=> x = 320 / 1
=> x = 1
Now, we have to plug this value into original function would give us the minimum (unit cost):
=> C(320) = 0.5(320)²- 320 (320) + 68,684.
=> C(320) = 0.5(102400) - 102400 + 68, 684
=> C(320) = 51200 - 102400 + 68684
=> C(320) = 17, 484
Therefore, the minimum unit cost is $17, 484

One batch of pink paint uses 2 cups of red paint and 7 cups of white paint. Mai made a large
Amount of pink paint using 14 cups of red paint.
1. How many batches of pink paint did she make?
2. How many cups of white paint did she use?
Answer:
Mai made 7 batches of pink paint.
Mai used 49 cups of white paint.
Step-by-step explanation:
Part 1. Every 2 cups of red paint are 1 batch of pink paint. This means to find the number of batches of pink paint Mai made, we need to divide 14/2. 14/2 = 7. This means she made 7 batches of pink paint.
Part 2. For every 2 cups of red paint, there are 7 cups of white paint.
For every 1 cup of red paint, there are 3.5 cups of white paint.
This means that we need to multiply 14 x 3.5.
14 x 3.5 = 49.
This means she used 49 cups of white paint.

What does your model predict the moose
population to be in 2006?
To answer this question we will use The Linear Programming concept
The formula for the moose population is
The moose population in 2006 would be
We use the year 1990 as the base year for creating the equation of the moose population. We could assume that:
The moose population of the year: P(x)
The moose population in year 1990: a
The year difference to 1990: x
The linear change of the moose population: b
Hence, we could make some assumption about the relationship between each elements mentioned above, where the moose population of the year would be depends on the linear change of the population added into the original moose population in year 1990. We could write this relationship into the equation (i):
P(x) = a + bx ... (i)
Using data provided from the question, we could make some other equations and find the value of b:
P(x) = a + bx
P(4) = a + 4b = 3280 ---> year 1994 ... (ii)
P(7) = a + 7b = 4120 ---> year 1997 ... (iii)
We could do some eliminations between equations (ii) and (iii)
3280 = a + 4b
4120 = a + 7b -
840 = 3b
b = 280 ... (iv)
After finding the value of b, we could subtitute its value into equation (ii) to find the value of a:
3280 = a + 4b
3280 = a + 4(280)
3280 = a + 1120
a = 2160 ... (v)
After finding the value of a and b, we could rewrite the equation (i) by inserting the and b values.
P(x) = a + bx
P(x) = 2160 + 280x ... (vi)
Next, we will predict the moose population to be in 2006.
First, we should determine the value of x, the difference between the year 2006 to the base year 1990.
x = 2006 - 1990
x = 16 ... (vii)
We would subtitute the equation (vii) into equation (vi) to predict the moose population to be in 2006:
P(16) = 2160 + 280(16)
P(16) = 6640...(viii)

What is a regular polygon?A polygon is a two-dimensional geometric figure that has a finite number of sides. The sides or edges of a polygon are made of straight line segments connected end to end to form a closed shape. The point where two line segments meet is called vertex or corners, and subsequently, an angle is formed. If a polygon contains congruent sides, then that is called a regular polygon.
The sum of the interior angles of a regular polygon = (n - 2) x 180
where n = number of sides of the polygon
here n = 20
Sum of the interior angle = (20 - 2) x 180
Sum of the interior angle = 3240°
which also means that 20(5h - 12) = 3240
100h -240 = 3240
100h = 3240+240

The graph of the quadratic function y = 1.5x² + 4x - 2 is given by the image shown at the end of the answer.
How to obtain the graph of a quadratic function?To obtain the graph of a quadratic function, these three features have to be obtained from the function's definition:
The x-intercepts, which are the roots of the function.The y-intercept, which is the value of y when the function crosses the y-axis.The vertex, which is the turning point of the function.The function for this problem is defined as follows:
y = 1.5x² + 4x - 2.
Hence the numeric values of the coefficients are listed as follows:
a = 1.5, b = 4, c = -2.
Inserting these coefficients into a calculator, the x-intercepts of the function are given as follows:
x = -3.09 -> hence the function passes through point (-3.09, 0).x = 0.43 -> hence the function passes through point (0.43, 0).The y-intercept of the function is given by coefficient c = -2, hence the function also passes through point (0, -2).
The x-coordinate of the vertex is given as follows:
x = -b/2a = -4/3 = -1.33.
Hence the y-coordinate of the vertex is of:
y = 1.5(-1.33)² + 4(-1.33) - 2 = -4.67.
Missing InformationThe problem asks for the graph of the following function:
y = 1.5x² + 4x - 2.

Gabe Amodeo, a nuclear physicist, needs 30 liters of a 60% acid solution. He currently has a 40% solution and a 70% solution. How many liters of each does he need to make the needed 30 liters
of 60% acid solution?
Gabe needs ___ of the 40% solution.
He needs 10 litres of solution of 40% and 20 litres of 70% solution to make 30 litres of 60% acid solution.
According to the question,
We have the following information:
Gabe Amodeo, a nuclear physicist, needs 30 liters of a 60% acid solution. He currently has a 40% solution and a 70% solution.
Now, let's take x litres of 40% solution and y litres of 70% solution.
So, we have the following expressions:
x+y = 30
x = 30-y ....(1)
40x/100 + 70y/100 = 30*60/100
Dividing 100 on the numerator by 100 on denominator:
40x+70y = 1800
Dividing both sides by 10:
4x+7y = 180
Putting the value of x from equation 1:
4(30-y)+7y = 180
120-4y+7y = 180
120+3y = 180
Subtracting 120 from both the sides:
3y = 180-120
3y = 60
y = 60/3
y = 20
Now, putting this value of y in equation 1:
x = 30-y
x = 30-20
x = 10
Hence, he needs 10 litres of 40% solution and 20 litres of 70% solution to make 30 litres of 60% acid solution.
