A scale factor is usually a decimal which scales, or multiplies, some quantity. In the equation y = Cx, C is the scale factor for x. C is also the coefficient of x, and may be called the constant of proportionality of y to x.

Answer:

2/5

Step-by-step explanation:

Since it's from a big square to a smaller square, the smaller number will be at the top. Also, use the same side to find the scale factor, but since this is a square and all sides of a square are equal, it doesn't matter but in other shapes it does so practice i guess:

Left side of big square: 5

Left side of small square: 2

So scale is 2/5

To confirm:

5 · 2/5 = 10/5 = 2, we're right

What is 50% of 64?
Dmitriy789 [7]

Answer:

50% = 50/100 = 0.5

20% = 20/100 = 0.2

25% = 25/100 = 0.25

10% = 10/100 = 0.1

Now let's begin our calculation

50% of 64=(0.5*64)=32

20% of 55=(0.2*55)=11

25% of 16 = (0.25*16) =4

10% of 200=(0.1*200)=20

20% of 86=(0.2*86)=17.2

Step-by-step explanation:

3 times (-8) times (-2)
dexar [7]

Answer:

48

Step-by-step explanation:

Signals during a multiplication of two numbers:

They have the same signal: The multiplication is positive.

They have different signals: The multiplication is negative.

3 times (-8) times (-2)​

First 3*(-8):

Different signals, so negative. 3*8 = 24. So the answer is -24.

Then:

3*(-8)*(-2) = (-24)*(-2)

Same signal, so positive. 24*2 = 48. The answer is 48.
