Answer:

Because it is a regular polygon, the sum of all exterior angles is equal to 360 degrees (one revolution). If each side has an exterior angle of 40 degrees, we simply divide 360 by 40 to get 9.

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

-5x + 6y = 55

4x + 3y = 34

Step 2: Rewrite Systems

4x + 3y = 34

Multiply everything by -2: -8x - 6y = -68

Step 3: Redefine Systems

-5x + 6y = 55

-8x - 6y = -68

Step 4: Solve for x

Elimination

Combine equations: -13x = -13
Divide -13 on both sides: x = 1

Step 5: Solve for y

Define equation: 4x + 3y = 34
Substitute in x: 4(1) + 3y = 34
Multiply: 4 + 3y = 34
Isolate y term: 3y = 30
Isolate y: y = 10

Convert 17.42 m to customary units. A.57'-17/8" B. 36-10 1/2" C. 442 1/2" D. 367/8" E. None of these answers is reasonable.

Allushta [10]

Answer:

E. None of these answers is reasonable.

Step-by-step explanation:

Customary units are inches, feet, yards, and miles.

Since,

1 foot = 0.3048 meters,

⇒ 1 meter = $\frac{1}{0.3048}$ feet,

17.42 meters = $\frac{17.42}{0.3048}$ feet

$=\frac{174200}{3048}\text{ feet}$

$=57\frac{ 464}{3048}\text{ feet}$

$=57\frac{58}{381}\text{ feet}$

Now, 1 feet = 12 inches,

⇒ $\frac{58}{381}$ feet = $\frac{12\times 58}{381}$ inches

= $\frac{232}{381}\text{ inches}$

Hence,

17.42 meters = $57\text{ feet }\frac{232}{381}\text{ inches}$

= 57' 232/127''

That is, None of these answers is reasonable.
