Answer:

175

Step-by-step explanation:

To find a proportion, you need to put both parts over the total.  You would put the part of silver (14) over the total (80) and the part you are trying to find (X) over the total number of students (1,000). Then you cross multiply 14 x 1,000 and divide by 80 giving you 175 silver cars.

Answer:

The true statement is h < k ⇒ (3)

Step-by-step explanation:

∵ The equation of the graph is y = \sqrt{x+h} + k

∵ (-h, k) are the coordinates of its vertex point

∵ -h is the x-coordinate of the vertex point

∵ x-coordinate of the vertex point is -3

∴ -h = -3

→ Divide both sides by -1

∴ h = 3

∵ k is the y-coordinate of the vertex point

∵ y-coordinate of the vertex point is 4

∴ k = 4

∵ 3 < 4

→ That means h is smaller than k

∴ h < k

∴ The true statement is h < k
