Answer:

  • 68.78° or 0.6 rad

Step-by-step explanation:

<u>Use the formula:</u>

  • degrees/360° = L/circumference
  • or
  • radians/π = L/circumference

<u>As per given:</u>

l = 12 feet, r = 10 feet

  • degrees = 360°*12/(2*3.14*10) = 68.78°
  • radians = π rad *12/(2π*10) = 0.6 rad

Dennis walks from (–5, –2) to (–5, 5) on the map. Which expression represents the distance that he walked? |-2| + |5| |-5 + 5| |
maks197457 [2]

Answer:

|-2| + |5|

Step-by-step explanation:

Dennis walks from (–5, –2) to (–5, 5) on the map.

Point on the format (x,y). On the x-coordinate, he stayed at the same position, x = -5, so it does not enter the distance calculation.

On the y-coordinate, he went from -2 to 5, so the distance is of:

d = 5 - (-2) = 5 + 2 = |5| + |2| = |5| + |-2| = 7

So the correct option is |-2| + |5|

Double the quotient of 3 and 6​
Hitman42 [59]

\huge{\boxed{1}}

This statement can be represented as 2*\frac{3}{6}, since the quotient is the answer to a division problem.

Divide. 2*\frac{1}{2}

Multiply. 2*\frac{1}{2}=\frac{2}{1}*\frac{1}{2}=\frac{2*1}{1*2}=\frac{2}{2}

Simplify.  When the numerator and denominator are the same, the fraction is equal to 1. \frac{2}{2}=1

(-5,3);5×=4y+9 can you help me solve ​
kompoz [17]

Answer:

-25 ≠ 21

Step-by-step explanation:

it looks like the question is asking you to solve 5x=4y+9 when given the ordered pair (-5,3)

you would substitute -5 for x and 3 for y in the equation

5(-5) = 4(3) + 9

-25 = 12 + 9

-25 = 21

the question is asking you to see if the left side is equal to the right side of the equation

-25 is not equal to 21, therefore (-5,3) is not a solution to the equation
