Grace [21]3 years ago
7 0

Answer:

30

Step-by-step explanation:

What number multiplied by 1/3 equals 10?

  n    x 1/3  = 10

  n/3 = 10    multiply both sides by 3 to get n by itself

3(n/3)  =  3(10)

n = 30

X is directly proportional to w²
umka21 [38]

The formula for x in terms of w is x = 3w² and the formula for y in terms of x is y = (1/112)x³

<h3>Variation</h3>

x = k × w²

w = 4, x = 48

48 = k × 4²

48 = k × 16

48 = 16k

k = 48/16

k = 3

So,

x = k × w²

x = 3 × w²

x = 3w²

y = k/x³

x = 2, y = 14

14 = k / 2³

14 × 2³ = k

14 × 8 = k

112 = k

So,

y = k/x³

y = 112/x³

y = (1/112)x³

The las answer is Center E and scale factor 1/4 pleaseee helpp
hoa [83]
<h3>Answer: D) center E, scale factor 1/4</h3>

======================================

Explanation:

Point E is the center of the dilation (we can think of this as the origin point). This is because point E is in the same exact location as point E'. This is a fixed point. The other points move.

To find the scale factor, divide E'F' over EF

scale factor = (E'F')/(EF)

scale factor = 2/8

scale factor = 1/4

Keep in mind that EF = EF'+F'F = 2+6 = 8.
