The percentage of oak trees is 16%.

Step-by-step explanation:

Given,

Number of oak trees = 200

Number of silver breech trees = 650

Number of wild cherry trees = 400

So,

Total number of trees = 200+650+400 = 1250

To find the percentage of oak trees.

Now,

The percentage of oak trees = $\frac{200}{1250}$ × 100%

= 16%

Hence,

The percentage of oak trees is 16%.

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 ..

Hello can someone help! i will make them brainliest!

Nady [450]

Answer:

B ( 92 degrees)

Step-by-step explanation:

1. Find y

In order to find z, we need to find y.

All triangles add up to 180 degrees, so y would be

180 - (48 + 44) = 88

y is 88 degrees

2. Find z

So now we know y is 88, we can find z

The circle of all angles of y and z = 360 ( because full angle)

so our equation is:

(88 + z)2 = 360

Divide by 2

88 + z = 180

z = 92
