Answer:
C. O.5s
Step-by-step explanation:
If the wave length is 100m and it goes at a speed of 200m/s then it will only take 0.5 seconds because 100 is half of the speed of 200
Left side:
x+x+x+1+1+1+1+1+1+1+1 = 3x + 8
Right side:
x+x+x+x++1+1+1+1+1+1
Left side = Right side to solve x
3x + 8 = 4x + 6
Subtract 4x from both sides
3x + 8 - 4x = 4x + 6 - 4x
Simplify
-x + 8 = 6
Subtract 8 from both sides
-x + 8 - 8 = 6 - 8
Simplify
-x = -2
Multiply both sides by (-1)
-x * (-1) = -2 * (-1)
Simplify
x = 2
Answer
C. x = 2
Answer:
The first one 3^7 *1/3-4
Step-by-step explanation:
Answer:
Step-by-step explanation:
Sum of all angles of triangle = 180°
6p + 6p + 3 p = 180
15p = 180
p = 180/15
p = 12
Angles are:
6p = 6*12 = 72°
3p = 3*12 = 36°
Angles are: 72°, 72° , 36°
1.
60² + 30² = 4500²
Opposite corner = 67.08 ft.
//
2.
6² + 8² = 100²
The wire must be 10 ft.
//
3.
7² + 14² = 245²
The rope is 15.65 ft.
//
4.
180² + 300² = 122400²
He ran 349.85 ft.
//
I'm not too sure about question 3.
