A = 28.356 ≈ 28.4

Here, we use law of sines, which says that sina / A = sinb / B. We know that b = 130 degrees, B = 10cm, and A = 6.2cm. Using algebra, we solve sina / 6.2 = sin130 / 10 to get a final answer.

babymother [125]

Answer: See explanation

Step-by-step explanation:

The dimensions of the first drawing will be 1/3 the dimensions of the leaf and the dimension of the oak leaf is 5 1/2 inches. Therefore, the dimensions of the 1st leaf:

= 1/3 × 5 1/2

= 1/3 × 11/2

= 11/6

= 1 5/6 inches

This is less than 5 1/2 inches

The dimensions of the second drawing will be 2 1/2 the dimensions of the leaf. This will be:

= 2 1/2 × 5 1/2

= 5/2 × 11/2

= 55/4

= 13 3/4 inches

Thus is greater than 5 1/2 inches

Jim paddles from one shore of a lake three miles wide at 4 mph, and John paddles from the opposite shore at 5 mph. How long will
AleksandrR [38]
D= distance
t= time
s= speed

FORMULA
Distance= speed * time

STEP 1:
Find total distance
Jim's D + John's D= 3 miles

STEP 2:
Distance= (Jim's speed * time) + (John's speed * time)
D= 4t + 5t
3 miles= 9t
divide both sides by 9
3/9= t
reduce by 3
1/3 hour= t

STEP 3:
1 hour= 60 minutes
=1/3 * 60
=(60/3)
= 20 minutes

ANSWER: They will travel 20 minutes before they meet.

Hope this helps! If it does, please mark me brainliest! :)
