Two old RSM students were standing ten feet apart when they ran in opposite directions with speeds of 180 feet per minute and 16
inessss [21]

The number of minutes that would pass before they were 1870 feet apart is 5.47 minutes

  • Since one student runs at a speed of 180 feet per minutes, in time t minutes, he moves a distance of d = 180t.
  • Also, the second student runs at a speed of 160 feet per minute, in time t minutes, he moves a distance of d' = 160t.

Since they are initially 10 feet apart, their total distance apart after t minutes is D = d + 10 + d'

D = 180t + 10 + 160t

D = 340t + 10

<h3>Number of minutes before they are 1870 feet</h3>

Making t subject of the formula, we have

t = (D - 10)/340

Since they are 1870 feet apart after t minutes, D = 1870 feet.

t = (D - 10)/340

t = (1870 - 10)/340

t = 1860/340

t = 5.47 minutes

So, the number of minutes that would pass before they were 1870 feet apart is 5.47 minutes

From the diagram below, if side DF is 4 cm., side CB would be ______.
kondaur [170]

The measure of CB from the given figure is 8cm

<h3>What is a triangle?</h3>

A triangle is 2 dimensional shape with 3 sides and angles. The types of triangle that we have are;

  • Equilateral triangle
  • Scalene triangle
  • Isosceles

The given triangle is a scalene triangle since <u>none of the sides are equal</u>

From the figure shown, we can see that the mea<em>sure of DF is equivalent to  CE and EB</em>

Since CB = CE + EB

Given the following parameter

DF = 4cm

CE = EB = DF = 4cm

Substitute

CB = 4cm + 4cm

CB = 8cm

Hence the measure of CB from the given figure is 8cm

A packing carton in the shape of a triangular right prism shown below. Find the volume of the prism.
Annette [7]

Answer: The volume is 120 in^3.

Step-by-step explanation:

-The volume formula for a triangular prism is:

(Height × Base × Length) /2

-So, you put the height, base, and length:

(4 × 6 × 10)

-Then, you solve:

(4 × 6 × 10)

(24 × 10)

240

-Divide 240 by 2:

240 ÷ 2

120

Therefore, the volume of a Triangular Prism is 120in^3.
