ANSWER

The area is 112.9 square units to the nearest tenth.

EXPLANATION

The circumference is given by:

$C=2\pi \: r$

This implies that,

$37.68 = 2 \: \pi \: r$

$\frac{37.68}{2\pi} = r$

$r = 5.997$

The area of a circle is

$\pi \: {r}^{2}$

We substitute the radius to get;

$3.14 \times 5.997 ^{2} = 112.93 \: sq. \: units$

To the nearest tenth, the area of the circle is 112.9 square units.

2. a. A fish is 12 meters below the surface of the ocean. What is its elevation?

Alex17521 [72]

Answer:

A. -12 meters

B. 28 meters

C. 40 meters

Step-by-step explanation:

The surface of the ocean would be 0.

Taking this into account, 12 meters below would be 0 - 12, which is -12. Therefore A's elevation would be -12.

For the sea bird, 28 meters above the surface, which is again 0, would be 0 + 28. B's elevation is 28.

Since the fish is 12 meters below the surface and the sea bird is 28 meters above the surface, simply add the two numbers up to get a total of 40 meters. C would be 40 meters.

Which expressions are equivalent to 1 divided m/6? Check all that apply

jenyasd209 [6]

Answer:

option A, option C, option D

Step-by-step explanation:

a) 1 ÷ m/6

can be written as

$\frac{1}{1}$ ÷ $\frac{m}{6}$

b) sides in (m/6) will change if both has to multiply

c) 1 ÷ m/6

can be written as

1 * 6/m

1( $\frac{6}{m}$ ) and wont make change to answer. so matches with the question.

1 ÷ m/6

1 * 6/m

1 * 6 * $\frac{1}{m}$

6 * $\frac{1}{m}$

6 ÷ m ..therefore true

1 ÷ m/6

1 * 6/m

6/m ....does not match or can be converted to the following so wrong

Therefore A, C, D are correct and B and E is wrong.

Enter the simplified form of the complex fraction in the box.

Ket [755]

The problem is:

$\frac{\frac{3}{x}+\frac{1}{4}}{1+\frac{3}{x}}$

We now do L.C.M. of numerator and add, also do L.C.M. of denominator and add together:

$\frac{\frac{12+x}{4x}}{\frac{x+3}{x}}$

Dividing by a fraction is same as multiplying by its reciprocal, so we have:

$\frac{12+x}{4x} * \frac{x}{x+3} \\$

x cancels out, so can multiply and write:

$\frac{12+x}{4} * \frac{1}{x+3} \\=\frac{12+x}{4x+12}$

This is the simplified form.

ANSWER: $\frac{12+x}{4x+12}$
