Answer:

The force used to fall by the head is

556.3N

Step-by-step explanation:

Given the the dragon's head has a mass m=56.7kg

Let us assume the acceleration due to gravity of the dragon's head is

9.81m/s^2

We know that the force

F=m*g

Substituting our data into the expression we have

F= 56.7*9.81

F= 556.2N

AnnZ [28]

Answer: C. 10 + 2h = 30

Step-by-step explanation:

  1. A does not make sense because the phone billing company would not be cutting off the money they earn while Jeremiah is on a call with someone.

  3. C makes sense because the phone billing company charges Jeremiah the total amount of his phone and $2 per hour he is on a phone call with someone.

lukranit [14]

Answer:

0.4

Step-by-step explanation:

If the ratio of boys to girls in a class is 2:3, then

  • there are 2x boys;
  • there are 3x girls.

If there are 18 girls in the class, then

3x=18\\ \\x=6

Thus, there are

  • 2\cdot 6=12 boys;
  • 3\cdot 6=18 girls;
  • 12+18=30 students in total.

The probability of a boy being in the class is

P=\dfrac{12}{30}=\dfrac{2}{5}=0.4
