defon
<h3>Answer:  2.4 pounds per dollar</h3>

Explanation:

We can set up the ratio

12 pounds : 5 dollars

Then divide both parts of that ratio by 5 so that the "5 dollars" becomes "1 dollar"

  • 12/5 = 2.4
  • 5/5 = 1

The ratio 12 pounds : 5 dollars is equivalent to 2.4 pounds : 1 dollar

Given that sin0=21/29 what is the value cos 0 for 0°&lt; 0&lt;90°
sp2606 [1]

Answer:

20/29

Step-by-step explanation:

sin θ = 21/29

Use Pythagorean identity:

sin² θ + cos² θ = 1

(21/29)² + cos² θ = 1

441/841 + cos² θ = 1

cos² θ = 400/841

cos θ = ±20/29

Since 0° < θ < 90°, cos θ > 0.  So cos θ = 20/29.
