=============

<h3>Given</h3>

  • cos \theta=\dfrac{\sqrt{3} }{2}

<h3>To find</h3>

  • The value of sin\theta

<h3>Solution</h3>

Use <u>identity</u> sin^2\theta+cos^2\theta=1 :

  • sin^2\theta=1-cos^2\theta
  • sin^2\theta=1-(\dfrac{\sqrt{3} }{2} )^2
  • sin^2\theta=1-\dfrac{{3} }{4}
  • sin^2\theta=\dfrac{{1} }{4}
  • sin\theta=\sqrt{\dfrac{{1} }{4} }
  • sin\theta={\dfrac{{1} }{2} }

Kali had a total of 212121 balloons at her birthday party. The ratio of blue balloons to green balloons is shown in the tape dia
Misha Larkins [42]

Answer:

Blue balloons = 12

Step-by-step explanation:

Total no of balloons = 21

Let us assume that the ratio of blue balloons to green balloons is 4:3.

Let there are 4x blue balloons and 3x green balloons.

ATQ,

4x+3x = 21

7x = 21

x = 3

Blue balloons = 4x

= 4(3)

= 12

Hence, she will have 12 blue balloons at her party.

It is different because you are doing a different method to complete the problem.  It is the same because it ends up with the same answer, provided you complete the process correctly.

A truck has a force of 2000 newtons and is moving 10 miles per hour. How much mass does the truck have?
worty [1.4K]

Answer:

Force= Mass×Accelaraion

F=m×a

But as The unit of accelaration is given miles per hour and the SI is meters per second sqaure we have to convert 10mph to m/s²

Thus, we have 10mph = 4.47 meters per second square. (i converted using scientific calculator)

So now we have,

2000N= m×4.47m/s²

= 2000/4.47m/s²=m

= 447.42

Thus the mass of the object is 447.42 (i am not sure of units)
