Answer:
Number of year, when final value is $61,412.50 = 3 year
Number of year, when final value is $20,000 = 10 year (Approx.)
Step-by-step explanation:
Given:
Depreciation model
y = 100,000[0.85]ˣ
Where x = Number of year
Find:
Number of year, when final value is $61,412.50
Number of year, when final value is $20,000
Computation:
Depreciation model
y = 100,000[0.85]ˣ
61,412.50 = 100,000[0.85]ˣ
0.614125 = [0.85]ˣ
x = 3
Number of year, when final value is $61,412.50 = 3 year
Depreciation model
y = 100,000[0.85]ˣ
20,000 = 100,000[0.85]ˣ
0.2 = [0.85]ˣ
x = 10 (Approx.)
Number of year, when final value is $20,000 = 10 year (Approx.)

Which expression represents the volume of the prism? One-halfx3 (one-half x) cubed Five-halvesx3 (Five-halves x) cubed
Answer:
Volume = ½x³ units.
Step-by-step explanation:
From the image, we can deduce the following;
Length = x
Breadth = x
Height = ½x
To find the volume of prism;
Mathematically, the volume of a prism is given by the formula;
Volume of prism = length * breadth * height
Substituting into the formula, we have;
Volume of prism = x * x * ½x
Volume = x² * ½x
Volume = ½x³ units

The length of a rectangle is 1 yd more than twice the width, and the area of the rectangle is 45 yd2 . Find the dimensions of the rectangle. Length : Width :
Answer: length = 10 yards
Width = 4.5 yard
Step-by-step explanation:
Let the width be represented by x.
Since the length of a rectangle is 1 yd more than twice the width. This will be:
= (2 × x) + 1
= 2x+1
Area = 45
Note that length × breadth = Area
(2x + 1) × x = 45
2x² + x = 45
Equate the equation to 0
2x² + x - 45 = 0
2x² + 10x - 9x - 45 = 0
2x(x + 5) - 9(x + 5) = 0
(2x - 9) = 0
2x = 9
x = 9/2
The width is 4.5 yard
Length = 2x + 1
= 2(4.5) + 1
= 9 + 1
= 10 yard
find a single discount equivalent to two successive discount of 20% and 5%
Answer:
Let the marked price =Rs100
After a discount of 20%, the price = 100−20% of100 = 100−10020×100 = 100−20=80
After a further discount of 5%, price = 80−5% of80 = 80−1005×80 = 80−4 = Rs76
Final Selling = Rs76
Total Discount = 100−76=Rs24
Thus, discount % = 10024×100 = 24%

5x - 7
23
Answer:
x = 6
Step-by-step explanation:
5x - 7 and 23 are vertical angles and are congruent , then
5x - 7 = 23 ( add 7 to both sides )
5x = 30 ( divide both sides by 5 )
x = 6

a system of equations is shown below 7x + 3y= 22. 3x - 3y =18 what is the solution to the system of equations
4,-2
distribute and combine like terms
Answer:
(4, -2)
Step-by-step explanation:
7x+3y= 22
3x-3y= 18
Add them in vertical columns. 7x + 3x = 10x. The 3y and the -3y cancel each other out. 22+ 18 = 40.
You're left with 10x = 40. Solve for x by dividing both sides by 10
x = 4
Plug in 4 into any of the original equations and solve for y.
7(4) + 3y =22.
28 + 3y =22
Subtract 28 on both sides
You're let with 3y = -6. Solve for y by dividing both sides by 3
y= -2
Put it together in coordinate point form. (4, -2)

Answer:
The answer is the second option. x = -5.873 , x = 1.873
Step-by-step explanation:
1. add 11 to both sides of the equation
x^2 + 4x = 11
2. find a value that is equal to the square of half of b
(b/2)^2 = (2)^2
3. add the term to each side of the equation
x^2 + 4x + (2)^2 = 11 + (2)^2
4. simplify the equation
x^2 + 4x + 4 = 15
5. factor the perfect trinomial square into
(x + 2)^2 • (x + 2)^2 = 15
6. solve the equation for x
x = 1.873 , x = -5.873
