1.) Claudia and her cousin Brian often ride their

bikes to meet each other. They live 16 miles

apart. Claudia can bike at a speed of 8.5 mph,

and Brian can ride 11mph. If they leave their

homes at the same time and bike toward each

other for half an hour, will they meet?

They do not meet.

Step-by-step explanation:

The distance between Claudia's house and her cousin Brian's house is 16 miles.

Claudia's speed is 8.5 miles per hour.

Brian's speed is 11 miles per hour.

If the part from their houses and travel for 0.5 hours, we have that the distance traveled by Claudia is equal to her velocity times the time she is biking, this is:

C = 8.5*0.5 = 4.25 miles.

So Claudia moves 4.25 miles towards Brian's house in this time, this means that Brian needs to move 16 miles - 4.25 miles = 11.75 miles.

Now, the distance that Brian moves is equal to his velocity times the time:

B = 11*0.5 = 5.5 miles

This is smaller than 11.75 miles, so they do not meet if they only bike for half an hour.

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
