Eudora ran from her home to her secret laboratory at an average speed of 12\text{ km/h}12 km/h12, start text, space, k, m, slash

Alekssandra [29.7K]

Answer:

Eudora ran for 30 minutes and use the jetpack for 1 hour and 30 minutes

Step-by-step explanation:

Lets call x the time she ran and y the time she was using a jetpack (in hours), we have

12x + 76y = 120

Since it took 2 hours we have that x+y = 2, hence y = 2-x. We can replace y in the equation above, obtaining

12x + 76(2-x) = 120

12x+ 152 - 76x = 120

12x-76x = 120-152

-64x = -32

x = -32/-64 = 1/2 (30 minutes)

As a result

y = 1-1/2 = 3/2 (1 hour, 30 minutes)

She ran for 30 minutes and use the jetpack for 1 hour and 30 minutes.

Rectangle ABCD is shown with diagonal AC drawn. Point F is on AC and point E on DC such that FE is perpendicular to DC. Prove tr

777dan777 [17]

Triangle ABC is similar to triangle CEF.

Explanation:

Diagram is inserted for the reference.

ABCD is a rectangle.

ABC is a right angled triangle because all the angles of the rectangle are 90◦ - (a)

CEF is a right angled triangle because FE is perpendicular to DC – (b)

In triangles ABC and CEF,

1. Angle ABC = Angle CEF = 90◦ (Both are right angles from a and b)

2. Angle BCA = Angle EFC (Alternate angles on parallel lines are equal on intersection)

Hence using Similarity property of AA (Angle, Angle), Triangle ABC and CEF are similar.
