38.75 to one decimal place is 38.8
Answer:
2/5
Step-by-step explanation:
0.4 = 4/10 which in simplest form is 2/5
A=πr²
pool=π(y-4)²=π(y²-8y+16)
total=π(y+4)²=π(y²+8y+16)
walkway=total-pool
walkway=π(y²+8y+16)-π(y²-8y+16)=
π(y²+8y+16-y²+8y-16)=
π(16y)=
16πy
first option is answer
Answer:
B
Step-by-step explanation:
Here, we want to choose the equation representing the time it will take if they worked together
Let the amount of tasks to be done be t
pedro will work at a rate of t/3
Camela will take t/2
So the joint rate will be
t/2 + t/3
This joint rate will be equal to 1
Thus, we have
t/2 + t/3 = 1
