Maybe if multiply 80 by 3 so you can find one of the answer then do it algebraic
180= x+24+6x+18+2x+30
180= 9x+72
108=9x
X=12
Answer: 90
Step-by-step explanation:
In the number 73,951, the digit 9 is on the third position, so you need to put the number of the position minus one zeros before it: ( position number 3, 3 - 1 = 2, so we put 2 zeros)
the 9 in that digit represents a 900.
now, 1/10 times that number is:
900*(1/10) = 900/10 = 90
then the answer is 90.
In the number 90, the value represented by the 9 is equal to 1./10 times the value represented by the 9 in 73,951
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
