8/11 is the answer

I use this trick: When tryig to find repeating numbers divide by 11 or 9

When dividing by 9 the numerator will be the first number in the decimal

When dividing by 11 the numerator will be one more than the first number in the decimal

Two skiers are 30 kilometers apart and head towards each other. They meet in 2 hours. If the second skier is 5 kilometers per ho

DENIUS [597]

Answer:

Speed of first skier = 5 km/h

Speed of second skier = 10 km/h

Step-by-step explanation:

Given:

Distance between skiers = 30 km

Time after which they meet = 2 hours

Second skier is 5 km/h faster than the first skier.

To find speed of each skier.

Solution:

Let the speed of first skier be in km/h = $x$

<em>Distance covered in km 2 hours will be = $Speed\times time=x\times 2=2x\ km$ </em>

Speed of second skier in km/h can be given as = $x+5$

<em>Distance traveled by second skier after 2 hours will be = $Speed\times time=(x+5)\times 2=(2x+10)\ km$ [Using distribution]</em>

Since, the skiers were 30 km apart initially, so the total distance covered by both of them when they meet after 2 hours will be = 30 km

Thus, we have:

$2x+2x+10=30$

Solving for $x$

$4x+10=30$

Subtracting both sides by 10.

$4x+10-10=30-10$

$4x=20$

Dividing both sides by 4.

$\frac{4x}{4}=\frac{20}{4}$

$x=5$

Speed of first skier = 5 km/h

Speed of second skier = $5+5$ = 10 km/h

State weather the triangles are similar .If so write a similarity statement and the postulate theorem you used.The triangles are

emmasim [6.3K]

Answer:

The answer in the procedure

Step-by-step explanation:

we know that

If two triangles are similar, then the ratio of its corresponding sides is equal and its corresponding interior angles are congruent

so

$\frac{OK}{ON}=\frac{OJ}{OM}$

substitute the values

$\frac{3}{4}=\frac{30}{40}$

$\frac{3}{4}=\frac{3}{4}$ -----> is true

Therefore

JK is parallel to MN

Triangles OMN and OJK are similar by AA Similarity Postulate ( The three interior angles are congruent)

Because

m<OKJ=m<ONM ----> by corresponding angles

m<KJO=m<NMO -----> by corresponding angles

m<JOK=m<MON -----> is the same angle
