Answer:

1/2 hour

Step-by-step explanation:

I am assuming you meant "lives 5km"

The first km would take 1/4 an hour because she is going 4km/h for one hour. One hour she would go 4km but we only need 1 mile so it would be cut to a fraction.

The same fraction goes for the bus. 4 is 1/4 of 16 so you would have to add them together and have 1/2 and hour to get home.

The lowest elevation in Lammefjord, Denmark, is 23 feet below sea level. The elevation of the Sea of Galilee in Israel is about
tatyana61 [14]

Answer:

Sea\ of\ Galilee = -690ft

Step-by-step explanation:

Given

Lowest\ Elevation = 23ft below sea level

Sea of Galilee = 30 times Lowest in Lammefjord, Denmark

Required

Determine the elevation of the Sea of Galilee

We have that the lowest elevation in Lammefjord is:

Lowest\ Elevation = -23ft

It is negative because, the elevation is below sea level.

Calculating the elevation of Sea of Galilee, we have:

Sea of Galilee = 30 times Lowest in Lammefjord, Denmark

Sea\ of\ Galilee = 30 * -23ft

Sea\ of\ Galilee = -690ft

<em>Hence, the elevation of Sea of Galilee is -690ft or 690ft below sea level</em>

Think About a Plan Write an indirect proof.
Alekssandra [29.7K]

1) Either \ell \parallel p or \ell ∦ p (only two possibilities)

2) Assume \ell \parallel p (one of two possibilities)

3) \angle 1 \cong \angle 2 (if two parallel lines are cut by a transversal, the corresponding angles are congruent)

4) But \angle 1 is not congruent to \angle 2 (given)

5) So \ell ∦ p (only other possibility)

Sergio039 [100]
50% because you first subtract the original price from the new price so 126-84 equals 42 then you divide that by the original price 84 which will give you .5 which turns to 50%
