Answers
the answer would be B. because 483.51-246.17=237.34
A tile factory earns money by a flat fee for delivery and sales price per tile sold. For one customer the tile factory shipped 10,000 units of retail stores at the rate of $0.25 Per tile. The total tile factory earned from that sale was 3000 which of the following equation describes the revenue of the tile from this sale in terms of tiles Sold? A) y=0.25x+10,000 B) y=0.25x+3,000 C) y=0.25x+500 D) y=0.25x+0.25
Answers
$0.25 X 10,000 = $2500. We now know what the total sales price per tile sold was $2500.
$3000 -$2500 =$0500
We now know that the flat fee was $500.
Therefore the equation describing the revenue of the tile from this sale in terms of tiles sold is y = 0.25x + 500 The answer is C)
If a thermometer indicates 30 degrees Celsius, what is the temperature in degrees Fahrenheit?A. 24°F B. 17°F C. 54°F D. 86°F
Answers
If a thermometer indicates 30 degrees Celsius, the temperature in degrees Fahrenheit is 86°F.
Boiling water measures 100 degrees in Celsius, and 212 degrees in Fahrenheit. Freezing water measure 0 degrees in Celsius, and 32 degrees in Fahrenheit.
So, if you want to convert Celsius into Fahrenheit, you will need to: Multiply by 180/100 Add 32
-5x+y=-33x-8y=24 solve this for me someone (solving systems of equations by substitutions) looking for x and y
Answers
(3)(-5x+y=-3) (5)(3x-8y=24)
-15x+3y=-9 15x-40y=120
3y=-9 -40y=120
-37y=111 Divide both sides by -37
y=-3
To solve for x. Choose one equation from the given and plug what you get in Y.
I'll choose, -5x+y=-3 So, -5x+(-3)=-3 -5x=0 Divide both sides by -5 x=0/-5
Hope, this helps.

You're working with two right triangles here.
The big one is the whole drawing. It's lying flat on its hypotenuse. One side of the big triangle ... the left side ... has no label. We'll be working with that side. Let's call it ' S ' .
The smaller triangle is the left piece of the big one. Its height is 'y', and its base is 4. ' S ' is its hypotenuse.
Go to your toolbox and pull out the little box marked "Pythagoras". Inside that box is the equation you need in order to work on this problem, or any problem with right triangles. The equation is ...
(hypotenuse)² = (length of one leg)² + (length of the other leg)² .
In the big triangle, 'x' is one leg, and the hypotenuse is 16 .
(16)² = x² + S²
256 = x² + S²
Subtract x² from each side: S² = 256 - x²
Take the square root of each side: S = √(256 - x²) ___________________________________
Now look at the small right triangle.
One leg is 4. The other leg is 'y'. The hypotenuse is ' S '.
S² = (4)² + y²
Subtract 16 from each side: y² = S² - 16
Writer in the value of S² that we worked out before: y² = (256 - x²) - 16 .
y² = 240 - x²
Take the square root of each side: y = √(240 - x²) .
That's what you're supposed to find. So we're done. _________________________________________
Oh phooey ! Sometimes I am so stupid.
Forget almost everything I did up above, and let's back up several steps:
==> Cut the picture along the line marked 'y', and throw away the left piece, with the '4' on the bottom. We don't need it.
-- Now you have a right triangle that I didn't even notice before. One leg is 12. The other leg is 'y'. The hypotenuse is 'x'.
Pythagoras says: (x²) = (12²) + (y²)
Subtract 12² from each side: y² = x² - 144
Take the square root of each side: y = √(x² - 144) .
We know that the shortest leg of the largest right triangle (hypotenuse length 16) has a length of the square root of (y^2 + 16) through the pythagoras theorem. We also know that x is equal to the square root of (144 + y^2) as well. Finally, we know that 256 = (y^2 + 16) + (y^2 + 144), since we use the pythagoras theorem one last time and square each of the values we have got for the two legs of the largest right triangle. Therefore, 256 = 2y^2 + 160, 96 = 2y^2, 48 = y^2, y= sqrt48 = 4sqrt3 = .
