\(\dfrac{1}{2}\cdot\dfrac{8}{13}+\dfrac{8}{13}\cdot\dfrac{3}{2}+\dfrac{8}{13}\cdot\left(-2\right)\)

\(=\dfrac{8}{13}\left(\dfrac{1}{2}+\dfrac{3}{2}-2\right)\)

\(=\dfrac{8}{13}\cdot0=0\)

  1/2 . 8/13 + 8/13 . 3/2 + 8/13 . (-2)

= 8/13 . (1/2 + 3/2 - 2)

= 8/13 . 0

= 0.

TK:
Robots can help us to save a lot of time at work. A robot can lift heavy things, build houses and make cars in factories. Robots can do the housework like cleaning the floors, making tea or coffee, doing the washing up, washing clothes, etc. In the future, robots will be able to talk to people, guard our houses, look after our children when we are away. Robots will be able to play sports and games with us and even drive a car when you are drunk or tired. Robots will be able to do many more complicated things and do almost everything instead of us. But one thing robots won’t be able to do is to think like humans.

I watched a movie called 'Wall-E.' It's about a small robot named Wall-E who cleans up trash on Earth. Earth is empty because it's too dirty for people. Wall-E is lonely until he meets another robot named EVE. Together, they go on a space adventure. The movie shows how Wall-E cares for Earth and finds love. I like this movie because it has funny and sad moments, and it teaches us to care for our planet.

Tỉ số phần trăm của 30m so với 70m là:

30 : 70  x 100% = 42,9% (70m)

Đáp số: 42,9% so với 70m

35 x 18 - 9 x 70 + 100

= 35 x 18 - 9 x 2 x 35 + 100

= 35 x 18 - 18 x 35 + 100

= 35 x (18 - 18) + 100

= 35 x 0 + 100

= 0 + 100

= 100

=35x9x2-9x70+100

=0+100=100
