Answer:

1.6%

Step-by-step explanation:

The hole has a diameter of 1 ft, or a radius of ½ ft.  The area of the hole is:

A = π r²

A = π (½ ft)²

A = ¼π ft²

The probability is therefore:

(¼π ft²) / (16π ft²)

1/64

≈ 1.6%

Answer: 5

Step-by-step explanation: Use a kind of probability which is called a geometric region probability. This is defined as

P = (measured of region in the event) / (measured of entire region)

The area of the entire region (circle) is given: 16 ft2

The area of the circular hole is A = πd2/4 = π (1) 2/4 = π/4 ft2

Hence, the probability is

P = (π/4) / 16 = 0.05 = 5%

Angelina_Jolie [31]

Answer/Step-by-step explanation:

well, first figure out how many units/times prism A was enlarged to become prism B...

16 ÷ 2 = 8

Now if we apply that info to the length of the prism, then...

80 ÷ 8 = 10

Therefore x = 10

And the Prisms remain congruent and proportional!

Tema [17]

Answer:

As per the given statement: when the lights go out at the store at night there's a 15% off sign hanging out by the make up counter.

To find the number as a decimal and a fraction in simplest form.

Given the Number = 15%.

If we convert any number from percent to decimal divide by 100 and remove the % sign.

\frac{15}{100} = 0.15

Then the given number in decimal is, 0.15

Now, to convert this percent into fraction;

\frac{15}{100}

Divide both numerator and denominator by 5 to get;

\frac{\frac{15}{5} }{\frac{100}{5} } = \frac{3}{20}

Therefore, the given number in fraction is; \frac{3}{20}

KatRina [158]

Answer:

Step-by-step explanation:

<em>Step 1:  Make an equation</em>

<em>400x = 450</em>

<u>Step 2:  Divide both sides by 400</u>

400x / 400 = 450 / 400

<em>x = 1.125</em>

<u>Step 3:  Convert into a percentage</u>

1.125 * 100

<em>%112.5</em>

<em>The increase is %12.5</em>

Answer:  %12.5
