A teacher is having three students take care of 28 goldfish during the summer. He gave some of them to Alaina. Then he gave twic
-Dominant- [34]

Answer:

Alaina got 4, Miguel got 2(4) = 8 while Kira got 2(8) = 16

Step-by-step explanation:

Let the number he gave to Alaina be x. Now, we know he gave twice as many to Miguel. Amount received by Miguel is 2x.

He gave Kira 2 times what he gave Miguel, that is 2x * 2 = 4x

Addition of all these equals 28. We now get x

4x + 2x + x = 28

7x = 28

X = 28/7

x = 4

Alaina got 4, Miguel got 2(4) = 8 while Kira got 2(8) = 16

An olympic hurdler accelerates at a rate of 15.5 m/s2 . what is the rate in miles/min2 ? 1. 6.89 miles/min2 2. 31.8 miles/min2 3
Tom [10]
For this case we have to take into account the following conversions:
 1 mile = 1609.34 meters&#10;&#10;1 minute = 60 seconds
 Let's first transform the expression to miles per seconds squared:
 (15.5) * (1 / 1609.34) = 0.009631277 mi / s ^ 2&#10;
 Then, we transform the result to miles per minute squared.
 We have then:
 (0.009631277) * (60) ^ 2 = 34.7 mi / min ^ 2&#10;
 Answer:
 
the rate in miles/min^2 is:
 
34.7 mi / min ^ 2
