<span><u><em>Answer:</em></u>
83.21 mm.<span>

<u><em>Explanation:</em></u>
<u>Circumference of a circle is is found by using the formula:</u>
C=πd.
C is the Circumference.
d is diameter.
π is the ratio for Pi,

<u>In this case we will use:</u>
3.14 instead of π
d = 26.5 mm

<u>Plug in the known values. </u>
C=(3.14)(26.5) = 83.21 mm</span></span>

Answer:

83.21 mm

Step-by-step explanation:

Given that The $1 coin here depicts Sacagawea and her infant son. The diameter of the coin is 26.5 millimeters.

Since for any circle we have

circumference of a circle =\pi d

where d = diameter of the circle =26.5 mm and pi = 3.14

Hence circumference = = 3.14(26.5) mm

=83.21 mm

A rectangle’s length is 5 inches more than twice its width. its area is 50 square inches. which equation can be used to find its
miss Akunina [59]

The equation of the area of the rectangle is w(2w + 5) = 50. Then the correct option is C.

<h3>What is a rectangle?</h3>

It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a rectangle, opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at the mid-point.

A rectangle’s length is 5 inches more than twice its width. its area is 50 square inches.

Let the width of the rectangle be w, then the length of the rectangle will be (2w + 5).

Then the area of the rectangle is given as

Area = l × w

Then we have

w(2w + 5) = 50

s344n2d4d5 [400]

Answer:

The number line that shows x > 8

Step-by-step explanation:

First, subtract 15 from both sides

<em>15 + 2x -15 > 31</em>

<em>2x > 16</em>

Then divide both sides by 2

<em>2x ÷ 2 > 16 ÷ 2</em>

<em>x > 8</em>
