Divide the shape into two parts, square triangle, the square is easy 2x2=4. The second part you know the length is 2 as 4-2=2, and because it is half of a square, it will be half of the area, so total answer is 6
1 metric ton is 1000 kilograms
2 metric tons is 2000 kg.
60 kilograms + 70 kilograms = 130 kilograms
2000 kg. + 130 kg. = 2130 kg.
The truck weighs 2130 kilograms.
The question is incomplete, the complete question is as follows:
What do Steven Hawking and Thomas Edison have in common
- Both men made mathematics discoveries
- Both men made discoveries that were well-received
- both men created technological inventions
- Both men used observations in their field of study
Answer:
- Both men made discoveries that were well-received
Step-by-step explanation:
Stephen Hawking and Thomas Edison were two great physicist or scientists, whose discoveries were well-recieved by all over the world.
Stephen Hawking gave theories in cosmology such as black holes that includes the second law, that states that black hole will never reduce its shape.
Thomas Edison was one of the great inventors in the history in different feilds such as mass communication, electric power generation, motion pictures, and sound recording. some of the inventions include Automatic Telegraph and tin foil phonograph.
They both have given scientific research and logics for their discoveries and so people accepted them.
Hence, the correct answer is " Both men made discoveries that were well-received
".
Solution:
Let x represent a number of calling minutes. According to the problem, we want:
now, putting the similar terms together, we obtain:
this is equivalent to:
now, solving for x, we get:
then, the correct answer for the first question is:
400 minutes is the number of minutes the two plans cost the same
now, for the second question, we can replace the above value (400 minutes) into the following equation:
so that, the correct answer for the second question is:
$55 is the cost when the two plans cost the same
Answer:
Step-by-step explanation:
hello :
let four consecutive whole numbers : n , n+1 , n+2 , n+3
the sum is : n + n+1 + n+2 + n+3 =4n+6
you can write 4n+6 to the form : 2(2n+3) means 2k ( k=2n+3)
so even number
