7/10 + 4/5

  • Make 4/5 have a common denominator with 7/10 by multiplying 4/5 by 2/2.
  • 4/5 * 2/2 = 8/10

Add 7/10 and 8/10.

  • 7/10 + 8/10 = 15/10

Simplify 15/10 by dividing both sides by 5/5.

  • 15/10 ÷ 5/5 = <u>3/2 </u>or<u> 1 1/2</u>

romanna [79]

Answer:

Correct option: (A) Someone with dangerous material that pass through security.

Step-by-step explanation:

Before boarding a flight every person has to pass through airport security.

The security checks every person thoroughly before they are confirmed as safe to go.

The security checks every person for some harmful substances like, weapons, chemical,etc.

If a person is caught with any of these objects the security stops them from boarding the plane.

So if a person is flagged as a risk by the airport security, he/she should have been carrying any kind of harmful substances.

Thus, the correct option is (A).

In a circle with a radius of 6 ft, an arc is intercepted by a central angle of 3π/2 radians.
slamgirl [31]

Answer:

Option 4 - L=9\pi ft.

Step-by-step explanation:

Given : In a circle with a radius of 6 ft, an arc is intercepted by a central angle of 3π/2 radians.

To find : What is the length of the arc?

Solution :

Length of an arc is given by:

L=r\theta

where r is the radius of the circle,  r= 6 ft.

and \theta is the angle in radian, \theta=\frac{3\pi }{2}

Substitute the value given in the formula,

L=r\theta   

L=6\times \frac{3\pi }{2}   

L=3\times3\pi

L=9\pi

Therefore, Option 4 is correct.

The arc of length is L=9\pi ft.
