Ok last week she walked 18/6 which equals 3 and 3 is less than 2.5. 2.5h is really just that times how many hours.D is the amount of miles.So,the awnser is going to be b or d.But we dont know what d is in d=2,5h so we have to asume that b is the awnser

Answer:

Last week, she walked a greater distance

Step-by-step explanation:

Rosemary walks each week for exercise. Let d represent the distance walked and h represent the number of hours spent walking.

Last week: walked 18 miles in 6 hours

Rosemary walked (18/6) = 3 miles per hour

This week: d = 2.5h

This week she walked 2.5 miles per hour

last week she walked 3 miles per hour that is greater than 2.5 miles per hour

So , Last week, she walked a greater distance

Xavier can swim at a constant speed of 5/3 meters/second.

koban [17]

Answer:

Step-by-step explanation:

Well we can find how far he travels in 55 seconds if he swims at constant speed of 5/3 meters.

5/3 times 55 = approx. 91.66 meters

Therefore Xavier will not quality for the national Swim Meet because he didn't swim 100 meters in 55 seconds

a sailmaker is designing a mainsail for a newly constructed sailboat. the mainsail foot is 13 feet long, the luff is 10 feet lon

Vikentia [17]

(A) The mainsail foot is 13 feet long, the luff is 10 feet long, the leach is 6.93 feet long, and the mainsail area is 64.85 ft².
(B) The mainsail foot is 13 feet long, the luff is 10 feet long, and the luff forms a 50° angle with the leach at the head, requiring the length of the leach and the area of the mainsail.

<h3>What exactly is sines law?</h3>

The law of sines refers to the ratio of a triangle's side length to the sine of the opposite angle, which is the same for all sides.
SinA/a = SinB/b = SinC/c
Where A, B, and C represent the triangle's angle and a,b, and c represent the opposite sides of the triangle's angle.

So, Part A:

By employing the sines law,

SinA/10 = SinB/13
SinA/10 = Sin50/13
A = 36.10
C = 180-(180-36.10)
C = 93.90

So,

Sin36.10 / a = Sin50/ b = Sin93.90/c
Sin36.10 / 10 = Sin50/ 13 = Sin93.90/c
c = Sin93.90 × 13 ÷ Sin50
c = 16.93 ft

Now, Part B:

Area of the mainsail:

= 1/2 × abSinC
= 1/2 × 10 × 13 × Sin93.90
= 64.85

Therefore, the answers to both parts are:

(A) The mainsail foot is 13 feet long, the luff is 10 feet long, the leach is 6.93 feet long, and the mainsail area is 64.85 ft².
(B) The mainsail foot is 13 feet long, the luff is 10 feet long, and the luff forms a 50° angle with the leach at the head, requiring the length of the leach and the area of the mainsail.

The complete question is given below:

A sailmaker is designing a mainsail for a newly constructed sailboat. The mainsail foot is 13 feet long, the luff is 10 feet long, and the luff makes a 50° angle at the head with the leach.

Part A: Determine the length of the leach.

Part B: Find the area of the mainsail.
