Step-by-step explanation:
3% × 90 =
(3 ÷ 100) × 90 =
(3 × 90) ÷ 100 =
270 ÷ 100 = 2.7
Answer:
Step-by-step explanation:
The slopes of the two lines (representing the speeds of the trains) are the same, and so the two trains are traveling at the same speed.
1.621 kN
Step-by-step explanation:
Let the centerline of the canal be the x-axis. Because the forces exerted by the horses are symmetric to the centerline, only the x-components of these forces contribute to the resultant force on the barge, i.e., the y-components cancel out. Each x-component is equal to
= 810.4 N. Therefore, the resultant force on the barge is twice this:


The equation is y=6.66666667x. This is because you get paid $6.66666667 per hour so you multiply that by the number of hours to get the total paid!
Lin's number = l
pazi's number = p
l = p + 7
p = p
p + 7 + p = 49
2p + 7 = 49
2p + 7 (-7) = 49 (-7)
2p = 42
2p/2 = 42/2
p = 21
l = p + 7
l = 21 + 7
l = 28
pazi is 21 years old, Lin is 28 years old
hope this helps
