There are 20 pieces of fruit in a basket and 12 of them are oranges what percentage of the pieces of fruit in the basket are orange show your work in the box and circle your answer
Total oranges in the basket = 20
Number of oranges = 12
what percentage of the pieces of fruit in the basket are orange
= Number of oranges / Total pieces of fruits × 100

= 0.6 × 100
= 60%
Percentage of the pieces of fruit in the basket that are oranges = 60%
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.
