Step-by-step explanation:
If I'm correct, to complete the square you need to use [tex](\frac{b}{2} )^{2}[/tex]
So, for #1, b is 10. [tex]\frac{10}{2}[/tex] = 5. [tex]5^{2}[/tex] = 25.
For #2, b is -6. [tex]\frac{-6}{2}[/tex] = -3. [tex]-3^{2}[/tex] = 9.

Answer:
y = 44°
Step-by-step explanation:
= 180 - 88
= 92°
y + y + 92° = 180°
2y = 180° - 92°
2y = 88°
y = 88/2
y = 44°
the marked price of an article , which is brought it for Rs 1280 is 25% above the cost price. if the discount is allowed and customer brought it for Rs 1540 including 10% Vat , what is the discount percent?
Answer:
I corrected my mistakes.
The discount percentage when the marked price of an article , which is brought it for Rs 1280 is 25% above the cost price should be 12.5%.
Calculation of the discount percentage:Since the cost price is 1280
Now the market price be like
= 1280 + 25% of 1280
= 1600
Now the selling price is
[tex]= 1540\div 1.1[/tex]
= 1400
Now the discount percentage should be
[tex]= (1600 - 1400) \div 1600[/tex]
= 12.5%
hence, The discount percentage when the marked price of an article , which is brought it for Rs 1280 is 25% above the cost price should be 12.5%.

11.) In the equation 6x = 84, what is the next step in the equation solving sequence?
Isolate the variable through inverse operations.
Solve for the variable.
Identify and move the coefficient or variable.
Combine like terms.
Answer:
Step-by-step explanation:
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-6*x-(84)=0
Step by step solution :
STEP 1: Pulling out like terms
1.1 Pull out like factors :
-6x - 84 = -6 • (x + 14)
Equation at the end of step 1:
STEP 2: Equations which are never true
2.1 Solve : -6 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
2.2 Solve : x+14 = 0
Subtract 14 from both sides of the equation :
x = -14
One solution was found :
x = -14
Answer: i think u should divide 84 by 6 to keep x alone the answer is x=14
but the answer depends on the sign of the variable .

what is the volume of a sphere with a radius of "60.5" Ft, Rounded to the nearest tenth of a cubic foot?
Answer:
[tex]volume = 927,587.2ft^3[/tex]
Step-by-step explanation:
The equation to find the volume of a sphere is as follows:
[tex]volume = \frac{4}{3}\pi r^3[/tex]
We have a radius of 60.5ft, let's plug this into the equation and solve:
[tex]volume = \frac{4}{3} \pi (60.5)^3 \\volume = 927,587.17\\volume = 927,587.2[/tex]
Therefore, the volume of a sphere with a radius of 60.5ft is 927,587.2ft^3.

Divide 16x3 – 12x2 + 20x – 3 by 4x + 5.
Answer:
[tex]4x^2 - 8x + 15 - \frac{78}{4x+5}[/tex]
Step-by-step explanation:
To solve polynomial long division problems like these, it's helpful to build a long division table. Getting used to building these can make problems like this much simpler to solve.
Begin by looking at the first term of the cubic polynomial.
What would we have to multiply [tex]4x + 5[/tex] by to get an expression containing [tex]16x^3[/tex]? The answer is [tex]4x^2[/tex], since [tex](4x + 5) \times 4x^2 = 16x^2 + 20x[/tex].
This is the first step of our long division, and we write out the start of our long division table like this:
[tex]{ }\qquad{ }\quad{ }\quad{ }\,\,\,\,\,4x^2\\4x + 5\quad)\!\!\overline{\,\,\,16x^3 - 12x^2 + 20x - 3}\\{ }\qquad{ }\quad{ }\quad{ }\,\,16x^3 + 20x^2\\[/tex]
On the left is the divisor. On top is [tex]4x^2[/tex]. In the middle is the polynomial we are dividing, and on the bottom is the result of multiplying our divisor by
The next step is to subtract the bottom expression from the middle one, like so:
[tex]{ }\qquad{ }\quad{ }\quad{ }\,\,\,\,\,4x^2\\4x + 5\quad)\!\!\overline{\,\,\,16x^3 - 12x^2 + 20x - 3}\\{ }\qquad{ }\quad{ }\quad{ }\,\,\underline{16x^3 + 20x^2}\\{ }\qquad{ }\quad{ }\quad{ }\,\,\,\,\,0x^3 - 32x^2\\[/tex]
We are left with [tex]-32x^2[/tex]. The next thing to do is to add the next term of the polynomial we are dividing to the bottom line, like this:
[tex]{ }\qquad{ }\quad{ }\quad{ }\,\,\,\,\,4x^2\\4x + 5\quad)\!\!\overline{\,\,\,16x^3 - 12x^2 + 20x - 3}\\{ }\qquad{ }\quad{ }\quad{ }\,\,\underline{16x^3 + 20x^2}\\{ }\qquad{ }\quad{ }\quad{ }\,\,\,\,\,\,\,\,\,\,\,\,\,\, - 32x^2 + 20x\\[/tex]
Now we return to the beginning of the instructions, and repeat the process: namely, what would we have to multiply [tex]4x + 5[/tex] by to get an expression containing [tex]-32x^2[/tex]? The answer is [tex]-8x[/tex], and we fill out our long division table like so:
[tex]{ }\qquad{ }\quad{ }\quad{ }\,\,\,\,\,4x^2 - \,\,\,\,8x\\4x + 5\quad)\!\!\overline{\,\,\,16x^3 - 12x^2 + 20x - 3}\\{ }\qquad{ }\quad{ }\quad{ }\,\,\underline{16x^3 + 20x^2}\\{ }\qquad{ }\quad{ }\quad{ }\,\,\,\,\,\,\,\,\,\,\,\,\,\, - 32x^2 + 20x\\{ }\qquad{ }\quad{ }\quad{ }\,\,\,\,\,\,\,\,\,\,\,\,\,\, - 32x^2 - 40x\\[/tex]
Once again, we subtract the bottom expression from the one above it, and include the next term of the divisor, like so:
[tex]{ }\qquad{ }\qquad{ }\quad{ }4x^2 - \,\,\,\,8x \,+ 15\\4x + 5\quad)\!\!\overline{\,\,\,16x^3 - 12x^2 + 20x - 3}\\{ }\qquad{ }\quad{ }\quad{ }\,\,\underline{16x^3 + 20x^2}\\{ }\qquad{ }\quad{ }\quad{ }\,\,\,\,\,\,\,\,\,\,\,\,\,\, - 32x^2 + 20x\\{ }\qquad{ }\quad{ }\quad{ }\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\underline{- 32x^2 - 40x}\\{ }\qquad{ }\qquad{ }\qquad{ }\qquad{ }\qquad{ }\,\,\,\,\,60x - 3\\[/tex]
And repeat. What do we multiply [tex]4x + 5[/tex] by to get an expression containing [tex]60x[/tex]? The answer is 15. Our completed long division table looks like this:[tex]{ }\qquad{ }\qquad{ }\quad{ }4x^2 - \,\,\,\,8x \,+15\\4x + 5\quad)\!\!\overline{\,\,\,16x^3 - 12x^2 + 20x - 3}\\{ }\qquad{ }\quad{ }\quad{ }\,\,\underline{16x^3 + 20x^2}\\{ }\qquad{ }\quad{ }\quad{ }\,\,\,\,\,\,\,\,\,\,\,\,\,\, - 32x^2 + 20x\\{ }\qquad{ }\quad{ }\quad{ }\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\underline{- 32x^2 - 40x}\\{ }\qquad{ }\qquad{ }\qquad{ }\qquad{ }\qquad{ }\,\,\,\,\,60x - 3\\{ }\qquad{ }\hspace{3cm}\,\,\underline{60x + 75}\\{ }\hspace{4.3cm}\,\,-78[/tex]
Now, the expression at the top,
[tex]4x^2 - 8x + 20x + 15[/tex]
is our quotient, and the last number, [tex]-78[/tex], is our remainder.
Hence we arrive at the solution of
[tex]\frac{16x^3-12x^2+20x-3}{4x+5} =4x^2 - 8x + 15 - \frac{78}{4x+5}.[/tex]

The diameter of the raw cookie is 2 1 2 inches. After baking the cookie, the diameter is 5 1 2 inches. By what factor does the cookie expand?
Answer:

Step-by-step explanation:
Given
[tex]Initial = 2\frac{1}{2}[/tex]
[tex]Final = 5\frac{1}{2}[/tex]
Required
Determine the factor of increment
First, we calculate the percentage increment
[tex]\% Increment = \frac{Final - Initial}{Initial} * 100\%[/tex]
Substitute values for Final and Initial
[tex]\% Increment = \frac{5\frac{1}{2} - 2\frac{1}{2}}{2\frac{1}{2}} * 100\%[/tex]
Express fractions as decimals
[tex]\% Increment = \frac{5.5 - 2.5}{2.5} * 100\%[/tex]
[tex]\% Increment = \frac{3}{2.5} * 100\%[/tex]
[tex]\% Increment = \frac{3* 100}{2.5} \%[/tex]
[tex]\% Increment = \frac{300}{2.5} \%[/tex]
[tex]\% Increment = 120 \%[/tex]
So, the factor of increment is:
[tex]Factor = 100\% + Increment[/tex]
[tex]Factor = 100\% + 120 \%[/tex]
[tex]Factor = 220 \%[/tex]
