The height of the triangle is 60cm, or 20cm+ 40cm.

The equation for area of a triangle is A=1/2bh

Your base is 30 cm height is 20cm.

A=1/2(30)(20)
A=1/2(600)
A=300cm^2

Your answer is 300cm^2

Answer:

height = (20 + 40) cm\\  = 60cm \\ area =  \frac{1}{2}  \times b \times h \\  =  \frac{1}{2 }  \times30 \times 60 \\   = \frac{1800}{2}  \\  area= 900 {cm}^{2}

Step-by-step explanation:

Convert 5.764764764 … to a rational expression in the form of a over b, where b ≠ 0
zubka84 [21]
I just learned a short time ago how to convert a repeating decimal to a fraction.

-- Take the repeating part of the decimal.  In this one, it's '764' .

-- Make a fraction out of it by writing it over the same number of 9s.

       The fraction here is        764/999 .

-- Simplify it if possible and if you feel like it.

         764/999 can't be simplified.  (I think.)

So the rational expressions for this decimal are

           (5 and 764/999)     or     5759/999   .

If a train traveled at 50 meters within 120 seconds, what is its speed?
Alja [10]

Answer:

v = 0.416 m/s

Step-by-step explanation:

Give that,

Distance covered by a train, d = 50 m

Time taken, t = 120 s

We need to find the speed of a train. The formula for speed of an object is equal to the total distance covered divided by total time taken. It can be given by :

v=\dfrac{d}{t}\\\\v=\dfrac{50\ m}{120\ s}\\\\v=0.416\ m/s

So, the speed of a train is 0.416 m/s.

Please heeeeeeeeelp! Ill give brainliest!
Alinara [238K]

Step-by-step explanation:

ok so as u know the angles of a triangle add up to 180.

So we will be using that for help.

S+R+T=180

12x+13x+12x-4+2-3=180

37x-5=180

37x=185

x=5

Now we will plug in the value for x to find each angle

S= 13(5)-4

=61

T=12(5)-3

=57

R=12(5)+2

=62

Hope this helped:)
