In the rectangle below,

STALIN [3.7K]

Answer:

Step-by-step explanation:

In a rectangle, diagonals are equal and bisect each other

BE = AE

6x - 5 = 2x + 7

6x - 2x - 5 = 7

4x - 5 = 7

4x = 7 + 5

4x = 12

x = 12/4

x = 3

AE = 2x + 7

= 2*3 + 7

= 6 + 7

AE = 13

AC = 13 + 13

AC = 26

m∠EBC = 50

In rectangle, each angle is 90

m∠ABE + m∠EBC = 90

m∠ABE + 50 = 90

m∠ABE = 90 - 50

m∠ABE = 40

In rectangle, AB // DC and DB transversal

m∠ECD = m∠ABE { alternate interior angles}

m∠ECD = 40

Dina and Masha start cycling on a 20 km bike path at the same time. When Dina reaches the end of the path, Masha still has 4 km

sammy [17]

Answer:

0.5 hour

Step-by-step explanation:

Given

Speed of Dina = 10 km/h

Distance = 20 km

So the time Dina taken to complete the track is:

$Speed=\frac{distance}{time}\\10=\frac{20}{time}\\time=\frac{20}{10}\\ time=2\ hours$

The time taken by Dina is 2 hours. As masha started with dina but she was 4 km of the path left to cycle,

her distance covered in 2 hours was:

$Distance\ covered\ by\ Masha\ in\ 2\ hours=20-4\\=16 km$

So we know the time and distance:

Now,

$Speed\ of\ Masha=\frac{distance}{time}\\ =\frac{16}{2}\\ =8\ kilometer\ per\ hour$

We have to calculate the time that will be needed by MAsha to complete the track:

As we know the speed and remaining distance

$Speed=\frac{distance}{time}\\8=\frac{4}{time}\\ time=\frac{4}{8}\\time=0.5\ hours$

Masha needs 0.5 hour to complete the track ..

If f (x) = x2 – 2x, find:<br> f(6) = [?]

Alexxx [7]

Answer:

f(6) = 24

Step-by-step explanation:

f(x) = x^2 - 2x

Let x = 6

f(6) = 6^2 - 2(6)

= 36 - 12

= 24
