Answer:
Speed of sound is 340 meter per second.
Step-by-step explanation:
Let the speed of sound = x meter per second.
It is given that,
The new mode of travel has the speed 170 meter per second, which is 50% less than the speed of sound.
So, we get,
x - 50%x = 170
i.e. x - 0.5x = 170
i.e. 0.5x = 170
i.e. x = 340 meter per second
Hence, the speed of sound is 340 meter per second.
Answer:
the value of y and x are 16times(9xdividedby5)
4y= 4times(9xdividedby5)
Step-by-step explanation:
Answer:
x = -1/3
x = 1
Step-by-step explanation:
The answer is Aimee divided out the factors 4 and 2 form 875
Olivia applied the scale factor to the measurements of the model she saw. We need to know those in order to calculate the new ones.
