The thiciness of a fingernail is about 1

topjm [15]

The thickness of a fingernail is about 10^-5 inch

From the complete question, we have the following parameter

Thickness = 1/100000 inch

To represent the thickness in standard form, we do the following:

Express the thickness as a decimal

Thickness = 0.00001 inch

So, the standard form would be:

Thickness = 1 * 10^-5 inch

This gives

Thickness = 10^-5 inch

Hence, the complete statement is:

The thickness of a fingernail is about 10^-5 inch

10. The formula for the circumference of a circle with diameter d is C = d.

Fudgin [204]

9514 1404 393

Answer:

a. d = C/π

b. d = 8/π inches ≈ 2.546 inches

c. r = 61/(2π) inches ≈ 9.708 inches

Step-by-step explanation:

a. The formula for circumference is ...

C = πd

Dividing by π gives ...

d = C/π

__

b. For a circumference of 8 inches, the diameter is ...

d = (8 in)/π = (8/π) in ≈ 2.546 in

__

c. The radius is 1/2 the diameter. So, the radius of a circle is ...

r = d/2 = (C/π)/2 = C/(2π)

For a circumference of 61 inches, the radius is ...

r = (61 in)/(2π) = 61/(2π) in ≈ 9.708 in

Find m KTL. Please I need help

Neko [114]

We know angles 3 and 4 = 123°. We also know that they are both located on a straight line, which is 180°. If we subtract 123 from 180, we get 57°, which is the size of the two angles in the smaller triangle KTL is located in.

Now, if we add up all the angles of a triangle, we get 180. With that knowledge, we can subtract 114° (57 x 2) from 180 and get out answer, which is 66°.
