Round 0.971 to the nearest tenth​
Flura [38]

Answer:

1.0

Step-by-step explanation:

You are rounding to the nearest tenth, so you should have only 2 places remaining (0.0). So, you look to the 7 to change the 9. 7 is bigger than 5, so you round 9 up. Since 9 plus 1 equals 10, the final answer is 1.0.

Hope this helps! :)

Sam and Harry are family. Sam is currently is three times Harry's age. Sam's age is also 10 more than twice Henry's age. What ar
kramer

Answer:

<em>Sam is 30 years old, and Harry is 10 years old.</em>

Step-by-step explanation:

Let us assume that the age of Sam is x and the age of Harry is y.

Sam is currently is three times Harry's age.

So, x=3y  ----------------------1

Sam's age is also 10 more than twice Harry's age.

so, x=2y+10  ---------------2

Subtracting 2 from 1, we get

\Rightarrow x-x=3y-2y-10

\Rightarrow 0=y-10

\Rightarrow y=10

putting this in equation 1,

x=3(10)=30

Therefore, Sam is 30 years old, and Harry is 10 years old.
