The original price of the laptop is calculated as $545

<h3>How to find the original Price?</h3>

We are given;

Sales Price of Laptop = $299.75

Now, the laptop is on sale for 45% off regular price.

If original price is x, then we can express that;

(100% - 45%) * x = 299.75

Thus;

55%x = 299.75

0.55x = 299.75

x = 299.75/0.55

x = $545

Thus, the original price of the laptop is calculated as $545

Solve the equation without the use of a calculator. please Help!!! Thank you!!!<br> 12x^3-30x=5-2x^2
nata0808 [166]

So, since we have a cubic equation with 4 terms, the first thing we should try is factoring by grouping, so:

12x^3+2x^2-30x+5 =0 \implies \\ 2x^2(6x+1)-5(6x+1)=0 \implies \\ (2x^2-5)(6x+1) = 0

Now that we've factored our equation, we can use ZPP and break it up:

2x^2-5 = 0 \implies \\ 2x^2=5 \implies\\ x^2=\frac{5}{2} \implies\\ x=\pm\frac{\sqrt{5}}{\sqrt{2}}=\pm\frac{\sqrt{10}}{2} \\ \\ 6x+1 =0 \implies \\ 6x=-1 \implies\\ x=\frac{-1}{6}

So, our solutions are:

x\in \{\frac{\sqrt{10}}{2},-\frac{\sqrt{10}}{2},-\frac{1}{6}\}

Which expression is equivalent to (4x^(3)y^(5))(3x^(5)y)^(2)
marshall27 [118]

Answer:

(4x^3y^5)(3x^5y)^2 = 36*x^{13}y^7

Step-by-step explanation:

Given

(4x^3y^5)(3x^5y)^2

Required

The equivalent expression

We have:

(4x^3y^5)(3x^5y)^2

Expand

(4x^3y^5)(3x^5y)^2 = 4x^3y^5*9x^{10}y^2

Further expand

(4x^3y^5)(3x^5y)^2 = 4*9*x^3*x^{10}y^5*y^2

Apply laws of indices

(4x^3y^5)(3x^5y)^2 = 36*x^{13}y^7

A rectangle that is 11.2 inches by 8 inches. The scale in the plan is 4in:5ft find the length and width or the actual studio. Fi
leonid [27]

Answer:

l=14\,ft\,\,\,\,w=10\,ft\\\\Area\,\,of\,\,actual\,\,studio=140\,ft^2\\\\

Step-by-step explanation:

As we know 1 ft has 12 inches.

scale\,\,in\,\,the\,\,plan=\frac{5\,ft}{4\, in}\\

We can find the length and width of studio by multiplying rectangle parameters with scale.

l=11.2\,in\times \frac{5\,ft}{4\,in}\\\\l=14\,ft\\\\w=8\,in \times \frac{5\,ft}{4\,in}\\ \\w=10 \,ft\\\\Area\,\,of\,\,actual\,\,studio=14\times 10=140\,ft^2\\
