Meryl needs to add enough water to 11 gallons of an 18% detergent solution to make

saveliy_v [14]

The percentage here must be assumed as by volume. Therefore, it means that the solution has 0.18 gallons of detergent / gallon of solution. If Meryl needs to add 11 gallons of water then she has 2.41 gallons of detergent. Calculation is as follows:

.18 = x / x+4

Solving for x, we obtain

x = 2.41

The point P(2k, k) is equidistant from A(-2, 4) and B (7,-5). Find the value of k.

mario62 [17]

Answer:

k = 3

Step-by-step explanation:

Using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = A (- 2, 4 ) and (x₂, y₂ ) = P (2k, k)

AP = $\sqrt{(2k+2)^2+(k-4)^2}$

Repeat

with (x₁, y₁ ) = B (7, - 5) and P = (2k, k)

BP = $\sqrt{(2k-7)^2+(k+5)^2}$

Given that AP = BP, then

$\sqrt{(2k+2)^2+(k-4)^2}$ = $\sqrt{(2k-7)^2+(k+5)^2}$

Square both sides

(2k + 2)² + (k - 4)² = (2k - 7)² + (k + 5)² ← expand factors on both sides

4k² + 8k + 4 + k² - 8k + 16 = 4k² - 28k + 49 + k² + 10k + 25

Simplify both sides by collecting like terms

5k² + 20 = 5k² - 18k + 74 ( subtract 5k² from both sides )

20 = - 18k + 74 ( subtract 74 from both sides )

- 54 = - 18k ( divide both sides by - 18 )

k = 3
