Answer:

The correct answer is 24

Step-by-step explanation:

To solve this math problem, you will need to <u>divide 20.40 with 1</u> (1 is 100% as a decimal) <u>and 0.15</u> (0.15 is 15% as a decimal).

$20.40$ ÷ $(1-0.15)$

First, subtract 1 and 0.15

$1-0.15=0.85$

Next, divide 20.40 and 0.85

$20.40$ ÷ $0.85 = 24$

Therefore, the final product of this math problem is 24

Which of the following correctly completes the square for the equation

rjkz [21]

Answer:

A. (x + 2)^2 = 31.

Step-by-step explanation:

x^2 + 4x = 27

x^2 + 4x - 27 = 0

A. (x + 2)^2 = 31

x^2 + 4x + 4 - 31 = 0

x^2 + 4x - 27 = 0

This option corresponds to the given equation, so it is correct.

B. (x + 2)^2 = 43

x^2 + 4x + 4 - 43 = 0

x^2 + 4x - 39 = 0

This does not correspond to the equation.

C. (x + 4)^2 = 31

x^2 + 8x + 16 - 31 = 0

x^2 + 8x - 15 = 0

This does not correspond to the equation.

D. (x+4)^2 = 43

x^2 + 8x + 16 - 43 = 0

x^2 + 8x - 27 = 0

This does not correspond to the equation.

So, your answer is A. (x + 2)^2 = 31.

Please help me find the perimeter.

slavikrds [6]

Answer:

31.42 cm (rounded up to two decimal places)

Step-by-step explanation:

We first find the circumference of the semi-circle segment:

The circumference will be given by; $\frac{1}{2}$ × π × D (where D is the diameter)

The diameter is 6 cm so circumference is;

$\frac{1}{2}$ × π × 6 cm = 9.42 cm (rounded up to two decimal places)

The perimeter of the figure therefore is;

8cm + 6 cm + 8 cm + 9.42 cm = 31.42 cm
