Answer:

ANSWER 4:3

Step-by-step explanation:

Given : A point P is 4/7 of the distance from M to N.

∴ Let the distance between M to N be d.

Also,  the point P partition the directed line segment from M to N .

Thus , MN = MP+PN

Now, the ration of MP to PN will be :-

∴ Point P partitioned the line segment MN into 4:3.

A, B and C are collinear points. B is between A and C. AB=12 BC=18 AC=3x Find X.
SCORPION-xisa [38]

Answer:

x =10

Step-by-step explanation:

Given

AB = 12

BC = 18

AC = 3x

Required

Solve for x

Since B is in between both points, then:

AC = AB + BC

This gives

3x = 12 + 18

3x = 30

Divide by 3

x =10

The speed of the current in a river is 6 mph. A ferry operator who works that part of the river is looking to
Morgarella [4.7K]

Answer:

  • 9 mph

Step-by-step explanation:

Let he speed of the boat on the lake is x.

<u>Considering the speed of the current it will take him:</u>

  • 22.5/(x + 6) + 22.5/(x - 6) = 9
  • 2.5 / (x  + 6) + 2.5 / (x - 6) = 1
  • 2.5(x - 6 + x + 6) = (x + 6)(x - 6)
  • 2.5*2x = x² - 36
  • x² - 5x - 36 = 0
  • x = (5 ± √(5² + 4*36))/2 = (5 ± 13) / 2
  • x = (5 + 13)/2 = 9 mph (negative root is discarded as the speed should be positive)

Please help me I will give you extra points and the brain thing
vovangra [49]

Answer:

A. n = 5

Step-by-step explanation:

S = n² + n

When S = 30:

                                                       n² + n = 30

Subtract 30 from both sides:  n² + n - 30 = 0

Factorize:                               (n - 5)(n + 6) = 0

Therefore                                                 n = 5 or -6

As n > 2, then n = 5 only

A Storage shed has the shape of an upside down cone. The shed has a volume of 209 cubic meters and is 10 meters wide. To the nea
Mrrafil [7]

Answer:

Height = 8 meters

Step-by-step explanation:

Given that

The volume V = 209 cubic meters Diameter = 10 meters

Radius r = 5 metres

How tall is the shed? The question is looking for the height of the cone

Using the formula for volume of a cone.

V = 1/3πr^2h

Where π = 3.14

209 = 1/3 × 3.14 × 5^2 ×h

209 = 3.14/3 × 25h

209 = 78.5h/3

h = 7.99 meters

h = 8 meters

Therefore, the shed is 8 meters tall.
