The correct ones are A,B, D&E
Answer:
The fastest runner is Brooke
Step-by-step explanation:
In order to determine this, we must first put them all in the same terms. For the purpose of this, we will put them all in feet per second.
Tony
12 feet/1 second = 12 ft per second
Brooke
381 feet/27 seconds = 14.11 ft per second
Emily
1 mile/499 seconds = 5280 feet/499 seconds = 10.58 ft per second
Frank
710 feet/1 minute = 710 feet/60 seconds = 11.83 ft per second
So we know that the fastest is Brooke
Step-by-step explanation: look so if you have
shcool A its 8v+4b=12
and
School B: 12v+4b= 16
since both classes used 4 busses we can use elimination by subtracting the A class Equation from the b class equation to solve from v for its value Then, use either equation and the now found value for v to solve for b.
You should find part of the process to be
12v+4b-(8v+4b)=12-16 which shows the van holds only a few people even before continuing the solution.
Answer -4
let assume x percent of 150 is 39
so
150 × x % = 39
150 × x/100 = 39
x = 39×100/150 = 26 % answer
