The Marine Discovery Aquarium sells ocean-themed cookies in their gift shop. Last month, they sold 65 shark cookies and 85 clown

Juliette [100K]

Answer:

130 shark cookies

Step-by-step explanation:

Number of shark cookies sold last month = 65

Number of clown fish cookies sold last month = 85

Ratio = $65:85=13:17$

Now, the Marine Discovery Aquarium plans to order 170 clown fish cookies this month.

So,

Number of shark cookies : Number of clown fish cookies = $13:17$

Number of shark cookies : 170 = $13:17$

Therefore,

Number of shark cookies = $\frac{13}{17}(170)=130$

The rule to remember about generating the perpendicular family to a line is we swap the coefficients on and x and y, remembering to negate one of them. Then the constant is set directly from the intersecting point.

So we have

y = 3x + 2

-3x + 1y = 2

Swapping and negating gets the perpendiculars; the constant is as yet undetermined.

1x + 3y = constant

Since we want to go through (0,2), we could have just written

x + 3y = 0 + 3(2) = 6

3y = -x + 6

y = (-1/3) x + 2
