Answer:
Last option
Step-by-step explanation:
Notice that the y-axis represents test scores. The lowest value on the y-axis is a 60.
The x-axis represents hours studied. The lowest value on the x-axis is a 0.
This implies a student who would study 0 hours would expect to score a 60 on the test.
2y+2=18 Subtract 2
2y = 16 Divide by 2
y = 8 Answer is y = 8
Answer:
circle P has a circumference of 800mm which is equal to 80cm
circle Q is 200cm
circle R is 4m which is equal to 400cm
You will get the sum of the distances by placing the figures under one measurement that is meters
And so add the figures in cm(200+400+80) and get 680
Then convert this to meters and get 6.8m
Hence your answer is C
Answer:
Step-by-step explanation:
Fist the velocity of high-speed train will be given by:
And the velocity of the regular will be given by:
The position equations of each movement will be given by:
We can get the encounter point isolating t in the first equation and reepalcing it in the second one:
First isolating:
Second reeplacing t:
In the moment of the encounter the high-speed train have gone round 
and the regular one 
Then the difference between the distance traveled the high-speed train and the regular one is:
The answer D is not true.
