Which expression represents the following statement: x is no less than 0. x>0 x≤0 x≥0 x<0
ki77a [65]

Answer: x ≥ 0

Step-by-step explanation:

First, let's define the symbols used:

a < x              (this means that a is strictly smaller than x)

a > x              (this means that a is strictly larger than x)

a ≤ x              (this means that a is smaller than or equal to x)

a ≥ x              (this means that a is larger than or equal to x)

Now we have the statement "x is no less than 0"

Then x can be equal to zero, or larger than zero, but never smaller than zero.

Looking at the symbols above, we know that we need to use:

x ≥ 0

(this is equivalent to the statement)

A metal washer has an outer diameter of 14mm and an inner diameter of 6mm.Use the value of 3.14 for the to find the area of the
Elena L [17]

Answer:

502.4 mm^2

Step-by-step explanation:

First find the area of the larger circle, and then that of the smaller one.

Then subtract the latter (2nd) area from the first.

larger circle area           smaller circle area

-------------------------           ---------------------------

 3.14(14 mm)^2                   3.14(6 mm)^ 2

This comes out to 3.14[14^2 - 6^2] mm^ 2 =  3.14[196 - 36] mm^2, or

3.14(160 mm^2) = 502.4 mm^2

The area of the metal washer is 502.4 mm^2.

Find the value of x.<br> Round to the nearest tenth.
tankabanditka [31]

Answer:

  x ≈ 42.3

Step-by-step explanation:

The law of cosines is given. For this problem, ...

  a = 25, b = 30, c = x , C = 100°

Filling in these values, we have ...

  x^2 = 25^2 +30^2 -2(25)(30)cos(100°)

  x^2 ≈ 1785.4723

  x ≈ √1785.4723 . . . . take the square root

  x ≈ 42.3
