Answer:
270
Step-by-step explanation:
Jones turns out 200 relays to Smith's 180. You set up that basic ratio and make a proportion out of it.
S/J = 180/200
Now you make your proportion
S/J = x/300
But the 2 ratios much remain the same.
180/200 = x / 300 Multiply both sides by 300
180*300/200 = x Multiply the numerator together.
54000/200 = x Do the division
270 = x
Smith will have turned out 270 relays.
Answer:
5.1 and 5.05
Not really much to explain. Still, hope this helped!
P.S. (5.2 is more than 5.03, btw)
Step-by-step explanation:
If you think about Nelia's age you can see that Olivia is 54 inches
Alano is 6 inches tall than Olivia which equals 60.
Then you would do 60 x 1 then x 30 to get Alano's height
As likely as not.
EXPLANATION: a coin has 2 sides. (usually heads and tails)
50% chance it is heads
50% chance it is tails
50=50.
So it is just as likely to happen as it is likely to not.
