WHAT THE HELL IS THIS!?!?!

Step-by-step explanation:

Answer 2

Answer:

B (12x=180)

Step-by-step explanation:

When you combine like terms for the numbers with x's, you get 12x and the -10 and 10 cross each other out. This leaves you with 12x=180 (since a triangle always adds up to 180).

A 40 kg-skier is standing at the top of a 12-meter high slope. What is her potential energy? PE = m x g x h (g = 10m/s2) A. 6000J B. 48J C. 4800J D. 400J

Answers

Answer:

The correct option is;

C. 4800 J

Step-by-step explanation:

The given parameters are;

The mass of the skier = 40 kg

The height of the slope = 12 meter

The acceleration due to gravity, g = 10 m/s²

The potential energy, PE, is given by the formula PE = Mass, m × Acceleration due to gravity, g × Height, h

Substituting the values, gives

The potential energy, PE = 40 kg × 10 m/s² × 12 m = 4800 kg·m²/s² = 4800 J

The potential energy, PE = 4800 J

Answers

Answer:-12, -10, -3.5, 6, 11

Step-by-step explanation:

Answer:

-12, -10, -3.5, 6, and 11

Step-by-step explanation:

The negative cycle is different from the positive. The greater the depth of the negative number, the less the value. So -12<-10 and -10<-3.5

-12, -10, -3.5, 6, and 11

There are 4 consecutive integers that have a sum of 338. What is the least of these integers?

Answers

Answer:

The least of the four integers is 83.

Step-by-step explanation:

Let x be the first integer.

x + (x + 1) + (x + 2) + (x + 3) = 338

4x + 6 = 338

4x = 332

x = 83

83 + 84 + 85 + 86 = 338

Step-by-step explanation:

1. b=c = 60° (vertically opposite angle)

60°+ z = 180° (linear pair)

a= 180°-60°= 120

a= 120°

2. 112°+ a= 180° (linear pair)

a= 180°- 112°= 68°

What is the solution of the equation 8(g - 18) =160

Answers

Answer:

g = 38

Step-by-step explanation:

8(g - 18) = 160

8g - 144 = 160

g = (160 + 144) / 8

g = 38

Answer:

g = 38

Step-by-step explanation:

8(g - 18) = 160

8g - 144 = 160

8g = 204

g = 38
