Unit rate = Number of feet / Number of seconds
=
=
feet per second
Answer:
Step-by-step explanation:
mid point formula = (x1+x2/2 , y1+y2/2)
hence putt the values we get,
mid point = ( -1+3/2 , 7-2/2)
= (1 , 2.5)
Divide 560 by 23, 23 goes into 560 24.347 times.
50*8=400
400+175=575
it subtracted 575 on the last round
Answer:
There is needed around 311 balloons to fulfill Mr. Schordine’s dream of flight.
Step-by-step explanation:
First, we need to calculate the volume of each balloon by considering the balloons as a sphere:

Where:
r: is the radius = 0.4 meters

Knowing that 1 m³ of helium is able to lift about 1 kg, that Mr. Schordine weights 84 kg, and that each ballon has 0.27 m³ of helium, the number of balloons needed are:
Therefore, there is needed around 311 balloons to fulfill Mr. Schordine’s dream of flight.
I hope it helps you!
