Points A, B, and C lie on line segment AC. The ratio of AB:BC is 3:7, and the length of AC = 120. What is the length of BC?

Answers

Answer 1

Answer: In terms of "ratio units," the length of AC is 3+7=10, so each one is worth 120/10 = 12. The length BC is 7 of those, or 7·12 = 84.

Answer 2

Answer:
The ratio of AB:BC is 3:7
3 + 7 = 10
the length of AC = 120
so 120 / 10 = 12

BC = 7 x 12 = 84

Answer
The length of BC = 84

A beluga whale is 5 yards and 3 inches long, and a gray whale is 15 yards and 5 inches long. What is the difference in length between the two whales?

Answers

Answer:

Difference in length between two whales is 362 inches or 10 yards and 2 inches.

Step-by-step explanation:

Lets convert the values to inches:

1 yard = 36 inches

Length of a beluga whale in inches:

5 yards = $5*36$ inches = $180$ inches

Therefore total length of a beluga whale = 180 inches + 3 inches

=183 inches

Length of a gray whale in inches:

15 yards = $15*36$ inches = $540$ inches

Therefore total length of a beluga whale = 540 inches + 5 inches

=545 inches

Difference in length between two whales = 545 inches - 183 inches

= 362 inches

To represent this in yards and inches we can divide the value by 36.

$(362)/(36) =10.06$ yards

=10 yards and 2 inches

Difference in length between two whales is 10 yards and 2 inches.

M(8, 7) is the midpoint of RS. The coordinates of S are (9, 5). What are the coordinates of R?

Answers

Answer:

M(Mx, My), R(Rx, Ry), S(Sx, Sy)

M is midpoint of RS

=> Rx + Sx = 2Mx => Rx = 2Mx - Sx = 2 x 8 - 9 = 7

=> Ry + Sy = 2My => Ry = 2My - Sy = 2 x 7 - 5 = 9

=> R(7, 9)

Hope this helps!

Answer:

(7,9)

Step-by-step explanation:

Let R:(x,y)

(x+9)/2, (y+5)/2 = 8 ,7

x + 9 = 16

x = 7

y + 5 = 14

y = 9

R: (7,9)
