The scale factor = 3.00

The scale factor of a circle to another is the ratio of their radii

Radius of the first circle = 9 in

Diameter of the second circle = 6 in

Radius = Diameter / 2

Radius of the second circle = 6 / 2

Radius of the second circle = 3 in

Scale factor = (Radius of the first circle) / (Radius of the second circle)

Scale factor = 9/3

Scale factor = 3.00 (2 decimal places)

Three of the choices are ways to express 0.50. Which is NOT?
Ganezh [65]

Option B

5 hundredths is not the way to express 0.50

<h3><u>Solution:</u></h3>

Given that Three of the choices are ways to express 0.50

To find: wrong option

Let us first write 0.50 in different ways

<h3><em><u>To convert a Decimal to a Fraction follow these steps: </u></em></h3>

Step 1: Write down the decimal divided by 1, like this: decimal 1.

Step 2: Multiply both top and bottom by 10 for every number after the decimal point. ...

Step 3: Simplify (or reduce) the fraction.

\rightarrow 0.50 = \frac{0.50 \times 100}{100} = \frac{50}{100}

\frac{50}{100} means 50 hundredths

<h3>Therefore option D is correct</h3>

On simplifying \frac{50}{100} we can write,

\rightarrow \frac{50}{100} = \frac{5}{10} = \frac{1}{2}

\frac{1}{2} means one half

<h3>Therefore option A (one half) is correct</h3>

Similarly, \frac{5}{10} means 5 tenths

<h3>Therefore Option C is also correct</h3>

Thus the wrong option is B

<em><u>Justification:</u></em>

5 hundredths can be written as:

\frac{5}{100} = 0.05

Therefore option B is wrong

Y equals 8<br> X equals 575<br><br> Solve for slope intercept <br><br> y equals mx + b
zhannawk [14.2K]

y = 8

x = 575

We want to solve for b in the slope-intercept form y = mx + b.

To complete this problem, we need the value of m, the slope. If you know m, then just plug into y = mx + b this way:

8 = 575m + b

How do I factorise 4 + 6x. Please show working out as well as answer, thanks!
Vaselesa [24]

Answer:

2(2 + 3x).

Step-by-step explanation:

The greatest common factor of 4 and 6x is 2, so we divide by 2 to get the factors:

4 / 2 = 2 and 6x / 2 = 3x so:

4 + 6x

= 2(2 + 3x).
