Answer:

The price of the drinks is $ 1.5 and the price of the bag of popcorn is $ 6.75

Step-by-step explanation:

We can solve by means of a 2x2 equation system, assuming that the question is the price of each product

We have to:

"x" price of drinks

"and" price of the bag of popcorn

9 * x + 4 * y = 40.5

3 * x + 5 * y = 38.25 => x = (38.25 - 5 * y) / 3

 replacing:

9 * (38.25 - 5 * y) / 3 + 4 * y = 40.5

114.75 - 15 * y + 4 * y = 40.5

-11 * y = 40.5 - 114.75

y = -74.25 / -11

y = 6.75

now for x:

 x = (38.25 - 5 * 6.75) / 3

x = 1.5

So the price of the drinks is $ 1.5 and the price of the bag of popcorn is $ 6.75

Mr. Autry bought a hat for $99.90. He also bought a pair of boots for $89.90. What was the total cost of the hat and boots inclu
Pepsi [2]

Answer:

$204.98

Step-by-step explanation:

Step 1: Add both item cost

99.90 + 89.90 = 189.80

Step 2: Find the sales tax of the result

\frac{8}{100}\times 189.8 = 15.184

  • Step 1: Convert 8% to fraction
  • 8\%= \frac{8}{100}
  • Simplify
  • \frac{8}{100} = \frac{2}{25}
  • Step 2: Convert 189.80 to a fraction
  • 189.80 = \frac{189.8}{1}
  • Step 3: Set it up
  • \frac{2}{25}\times \frac{189.8}{1}
  • Step 4: Cross divide
  • 189.80 \div 25 = 7.592\\2 \div 1 = 2
  • Step 5: Multiply the result
  • 7.592 \times 2 = 15.184

Step 3: Add the result from the total cost of both items

189.80 + 15.184 = 204.98

The total cost of the hats and boots including sales tax is 204.98 dollars

rectangle q has an area of 2 square units thea drew scaled version and labled it rectangle r what scale factor did thea use to g
alexgriva [62]

Answer:

<em>It has been given that Rectangle Q has an area of 2 square units.</em>

<em>Thea Drew a scaled version of Rectangle Q and marked it as R.</em>

<em>As you must keep in mind If we draw scaled copy of pre-image, then the two images i.e Pre-image and Image are similar.</em>

<em>As you have not written what is the scale factor of transformation</em>

<em>Suppose , Let the Scale factor of transformation= k</em>

<em>Rectangle Q = Pre -image, Rectangle R= Image</em>

<em>If, Pre-Image < Image , then scale factor is k >1.</em>

<em>But If, Pre-Image > Image , then Scale factor will be i.e lies between, 0<k<1.</em>

How to integrate a/1-ay?
AysviL [449]
In private correspondence with the author of the question, it was determined
that 'y' is the variable of integration.

Therefore, 'a' is a constant for purposes of this integration, and that whole
'a' business can be taken outside the integral.

Integral [a/(1-ay) dy] = a/(1-a) integral [dy/y] = a ln(y)/(1-a)    +  C

Here is a picture of a cube, and the net of this cube.
nekit [7.7K]
The surface area of the cube is 864mm.

I found this by find the surface area of one of the squares first.  To find this, you take the measurement of one side and multiply it by itself.  So the surface area of one of the squares in the net is 144mm.  Then all you do from there is multiply that number by how many squares there are in the net.  So your answer is 144 x 6 which equals 864.

Hope this helps! :)
