The price of a video game increases by 20%, then decreases by 10%. If the final price is $46.98,

Elena-2011 [213]

Answer:

The original price was $43.50

Step-by-step explanation:

Let

x ----> the original price of a video game

we know that

1) The price of a video game increases by 20%

$100\%+20\%=120\%=120/100=1.20$

The final price is equal to the original price multiplied by 1.20

$1.20x$

2) The price of a video game decreases by 10%

$100\%-10\%=90\%=90/100=0.90$

The final price is equal to the price at this moment multiplied by 0.90

$0.90(1.20x)=1.08x$

we have that

$1.08x=46.98$

solve for x

$x=46.98/1.08\\x=\$43.50$

What is the simplest radical form of the expression? (x^3y^5)^(4/3)

$\bf ~\hspace{7em}\textit{rational exponents} \\\\ a^{\frac{ n}{ m}} \implies \sqrt[ m]{a^ n} ~\hspace{10em} a^{-\frac{ n}{ m}} \implies \cfrac{1}{a^{\frac{ n}{ m}}} \implies \cfrac{1}{\sqrt[ m]{a^ n}} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ (x^3y^5)^{\frac{4}{3}}\implies \left( x^{3\cdot \frac{4}{3}}y^{5\cdot \frac{4}{3}} \right)\implies x^4y^{\frac{20}{3}}\implies x^4 y^{\frac{18}{3}+\frac{2}{3}}\implies x^4 y^{\frac{18}{3}} y^{\frac{2}{3}} \\\\\\ x^4y^6 y^{\frac{2}{3}}\implies x^4y^6\sqrt[3]{y^2}$

I need serious help, I forgot how to do this ;-; I haven't done that kind of math in a long time. How can I find the answer and

larisa [96]

Answer:

I think your answer is 85. The 50 degree angle on the left side of E is equal to the angle to the right of E. Since both triangles have equivalent angle measurements, D and B are correspondent of one another. Add the 50 degrees to the 45 degrees to get 95. Since triangles total measurements equal 180, subtract 95 from 180 to get 85. Angle D = 85, and since Angle B is correspondent, Angle B = 85°

Please help with the question below!

(answer in big text in the end :D )

1. Calculate the SA of all the sides...

There are 5 sides in this shape. 2 sides are Triangles, and 3 are rectangles. Let's call the rectangle on the base, base rectangle, let's call the large rectangle on the right, right rectangle, and the left on on the side, left rectangle. Just so that we can identify them...

Now, first, we will calculate the Triangular parts' surface area. There is a tip in this, as we know, to calculate the area of 1 triangle, we have to use this formula... $SA=\frac{1}{2} *B*H$ BUT! that's only for calculating 1 triangle, not 2, but we have 2 here, to use this shortcut, we will just do BxH not 1/2xBxH

Let's do it!

Base of triangle: 9.8ft

Height of triangle: 5.33ft

Now, we have to multiply these

9.8x5.33=52.234

Rounding to the nearest tenth... 52.2

Then, let's do the base rectangle

Length of rectangle: 9.8ft

Width of rectangle: 3.8ft

Now, multiply!

9.8x3.8=37.24

Rounding to the nearest tenth... 37.2

Now, let's do the Right Rectangle

Dimensions:

Length of rectangle: 8.5ft

Width of rectangle: 3.8ft

multiply...

8.5x3.8=32.3

no rounding in this, it's already rounded to the nearest tenth

Now, let's do the left rectangle...

Dimensions:

Length of rectangle: 6.2ft

Width of rectangle: 3.8ft

6.2x3.8=23.56

Rounded to nearest tenth... 23.6

2. Now that we have gotten the SA's of all of the shapes in this triangular prism, let's ADD them together to get our FINAL answer.

All the answers are: 52.2, 37.2, 32.3, and 23.6

<h2>adding them, our answer is: 145.3ft²</h2>
