Answer:

E

Step-by-step explanation:

.03(50) + 0x = (50-x).05  How much 3% salt much be added to zero percent salt to create a mixture that is 5 percent salt.

3(50) = (50 - x)5  I multiplied through by 100 to clear the decimals

150 = 250 - 5x  Distribute the 5

-100 = -5x  Subtract 100 from both sides of the equation

20 = x divide both sides by -5

Which of the following terms best describes the set of all points in a plane for which the difference between the distances of a
Gnoma [55]

Answer:

HYPERBOLA

Step-by-step explanation:

We have the statement,

'The set of all points in a plane for which the difference between the distances of a given point to two fixed foci equals a certain constant'.

We know that,

Hyperbola is the set of points such that for point P anywhere on the curve, the absolute distance to the two fixed points is a constant.

i.e. From the figure, we see that, the difference of the distance of P from F_{1} and F_{2} is equal to constant 2a.

Thus, the term representing the given statement is HYPERBOLA.

Find the length of XY
Pachacha [2.7K]

Since this is a right triangle, you can use the pythagorean theorem, leg^2+leg^2=hypotenuse^2, to find XY. Since we know that 15 and 17 are our legs and that XY is the hypotenuse, we can solve it as such:

15^2+17^2=XY^2\\ 225+289=XY^2\\ 514=XY^2\\ \sqrt{514}=XY

In short, XY is √514, or 22.67 rounded to the hundreths, units long.
