Answer:
IJ is going to be 5400.
Step-by-step explanation:
60*90= 5400.
90 is the right angle on J.
I is 60 degrees.
Neither, you just multiply the numerators to get 1, then multiply the denominators to get 6. It is 1/6
We breakdown the components of the distances.
(1) 90 miles west.
x - component = -90 miles
y - component = 0 miles
(2) 80 miles, northwest (120°)
x - component = (80 miles)*(sin 30°) = 40 miles (negative)
y - component =(80 miles)*(cos 30°) = 69.282 miles (positive)
Solve for the distance,
√(-90 - - 40)² + (69.282 miles)² = <em>147.31 miles</em>
Answer:
x = 11
Step-by-step explanation:
(0.3x - 2.1)/3 = 0.4
0.3x - 2.1 = 0.4 * 3
0.3x - 2.1 = 1.2
0.3x = 1.2 + 2.1
0.3x = 3.3
x = 3.3/0.3
x = 11
