About how far does the flag have to travel to complete full rotation?1. 37.68 ft2. 75.36 ft3. 150.72 ft4. 452.16 ftPlease explai
Fofino [41]

Due to the circular shape, one complete rotation of the flag is equal to the circumference of a circle with radius 12 ft.

Then, use the following formula for the cirumference:

C = 2π·r

where r is the radius. In this case, r = 12 ft and π = 3.14. Replace the previous values into the formula for C:

C = 2(3.14)(12 ft)

C = 75.36 ft

Hence, the flag has to travel 75.36 ft to complete a full rotation

Which side lengths form a right triangle
aleksandrvk [35]

Answer:

A and C

Step-by-step explanation:

  • A right triangle consists of two legs and a hypotenuse.
  • To find hypotenuse, we use The Pythagorean Theorem
  • The Pythagorean Theorem = {a}^{2}  +  {b}^{2}  =  {c}^{2}
  • two legs meet at a 90° angle and the hypotenuse is the longest side

3 - 4 - 5

6 - 8 - 10

7 - 24 - 25

5 - 12 - 13

are some basic right triangle

(about more, look picture)

<em><u>Just use hypotenuse formula :</u></em>

3 x 3 = 9

4 x 3 = 12

5 x 3 = 15

Option C is correct

{5}^{2}  +  { \sqrt{6} }^{2}  =  { \sqrt{31} }^{2}

Option A is correct

{5}^{2}  +  {5}^{2}  =  { \sqrt{50} }^{2}

But B isn't correct

Hope this helps ^-^

Need help on this equation
Strike441 [17]

Answer:

<h3>x =1 </h3>

Step-by-step explanation:

Given the following DE = 4X-2

EF = 3x+2

FG 5x-3

GD = 2x+5

Since DE is parallel to GF, this means that the sides are equal hence;

4x - 2 = 5x - 3

4x - 5x = -3 + 2

-x = -1

x = 1

<em>Hence the value of x is 1</em>
