Thank you for posting your question here at brainly. I assume the question should be "Find the number indicated". below is the answers:

B U C means B union C which combines them:
{Frans, Sarie, Tina, Klaas, Henrika, Hans} note that there is no need to write Frans twice. 

∩ means intersection which is only what the two sets have in common, in this case: 
{Frans, Sarie} 

the number is 2.

#2 only And it's to confusing

ipn [44]

They are easy to compare if they all have the same common denominator, then you can easily order them by the magnitude of the numerators...

85/10, -67/10, -56/10, 82/10 so now they are easy to compare...so

-6.7, -28/5, 8.2, 17/2

What is a peregrine falcon's maximum speed while diving to catch prey,

Sergeu [11.5K]

This is an incomplete question, here is a complete question.

What is a peregrine falcon's maximum speed while diving to catch prey 200 miles per hour in feet per second? (Round your answer to the nearest whole number. (1 mile = 5280 feet)

Answer : The speed in feet per second is, 293 feet/s

Step-by-step explanation :

As we are given that the speed of peregrine falcon's is 200 miles per hour. Now we have to determine the speed in feet per second.

As we know that:

1 mile = 5280 feet

1 hour = 3600 second

So,

1 mile/hr = 1.4667 feet/s

As, 1 mile/hr = 1.4667 feet/s

So, 200 mile/hr = $\frac{200\text{ mile/hr}}{1\text{ mile/hr}}\times 1.4667\text{ feet/s}$

= 293.34 feet/s ≈ 293 feet/s

Therefore, the speed in feet per second is, 293 feet/s
