dem82 [27]

Answer:

a) 0.6435 radians

b) 80.1 feet/sec

Step-by-step explanation:

a) 75 = (50²/16)sin(theta)cos(theta)

sin(theta)cos(theta) = 0.48

2sin(theta)cos(theta) = 0.96

sin(2theta) = 0.96

2theta = 1.287002218

Theta = 0.6435011088 radians

b) 200 = (v²/16)sin(0.75)cos(0.75)

6416.072347 = v²

v = 80.10038918 feet/sec

Solve for x 2/7x = 6 (SHOW YOUR WORK)

castortr0y [4]

Answer:

The answer to your question is x = 21

Step-by-step explanation:

Equation

$\frac{2}{7} x = 6$

- Multiply both sides by 7

$\frac{(2)(7)x}{7} = 6(7)$

- Simplify

2x = 42

- Divide both sides by 2

$\frac{2x}{2} = \frac{42}{2}$

- Simplify

x = 21

Explain how you know that21/30 is greater than 2/3

JulijaS [17]

You can divide 21 by 30 and that would give you 0.7 and if you divide 2 by 3 that would give you 0.6 repeating. Therefore, that is how I know that 21/30 is greater than 2/3.
