<h2> $\huge \mathfrak \orange{Question}$ </h2>

Two bikers are riding a circular path.

The first rider completes a round in 12

minutes. The second rider completes

a round in 18 minutes. If they both

started at the same place and time

and go in the same direction, after

how many minutes will they meet

again at the starting point?

<h2> $\huge \mathfrak \orange{Solution}$ </h2>

$\huge \mathsf \blue{Given}$

First rider takes 12 minutes to complete a round.
Second rider takes 18 minutes to complete a round.

$\huge \mathsf \blue{To\: Find}$

After how many minutes will they meet

again at the starting point?

Take the LCM of 12 and 18

12 = 2 × 2 × 3

18 = 2 × 3 × 3

Thus, the LCM of 12 and 18 is 36.

<h3>So they will meet after 36 minutes again at the starting point.</h3>

Answer:

Find the LCM of 12 & 18 .

12 = 2×2×3

18 = 3×3 ×2

So , LCM of ( 12 , 18 ) = 2×3×2 = 36

<h2>Therefore he meet after 36 minutes at starting point..!!</h2>

Answer:

x = 28, y = 34

Step-by-step explanation:

70 + 4x - 2 = 180

110 = 4x - 2

112 = 4x

x = 28

(y + 9) + (y - 1) + 2(y - 4) = 136

4y = 136

y = 34

-6-8g is less than -11

leva [86]

Answer:

g>5/8

Step-by-step explanation:

Step 1: Simplify both sides of the inequality.

-8g-6<-11

Step 2: Add 6 to both sides.

−8g−6+6<−11+6

−8g<−5

Step 3: Divide both sides by -8.

−8g/−8<−5/−8

= g<5/8

Answer:

Base angles = 40°

Vertex angle = 100°

Step-by-step explanation:

Look at the attached figure.

The external angle, is the angle outside the triangle. An isosceles angle has two base angles and a vertex angle. The base angles are congruent.

The external angle and one of the base angles (the one beside the external angle) are supplementary, this means that the sum of their angles is 180°.

With that, we can solve for one base angle:

base angle + external angle = 180°

base angle + 140° = 180°

base angle = 180° - 140°

base angle = 40°

So the base angles each have a measurement of 40°

Okay, now that we know this, we can solve for the , so there are two ways to do this.

I: The sum of the internal angles is equal to the external opposite them. Then the vertex angle + a base angle = external angle

vertex angle + 40° = 140°

vertex angle = 140° - 40°

vertex angle = 100°

The vertex angle is 100°.

OR YOU CAN DO THIS:

II. The sum of all angles in a triangle is equal to 180°.

Base angle + Base angle + Vertex Angle = 180°

40° + 40° + Vertex angle = 180°

80° + Vertex angle = 180°

Vertex angle = 180° - 80°

Vertex angle = 100°
