Answer:
30 minutes
Step-by-step explanation:
if every minute was 30 seconds, you just cut everything in half. so, if an hour is 60 minutes, the new number would just be 30 minutes.
i hope this helps!
Answer:
Where are the expressions?
Hey there!

Use the pythagorean theorem:
a² + b² = c²
a will be rise and b will be run.
Distance between 9 and 2 is 7.
Distance between 3 and 0 is 3.
Plug those into the equation.
7² + 3² = c²
Square.
49 + 9 = c²
Add.
58 = c²
Square root both sides.
√58 = c
This is the distance in radical form.
Hope this helps!
what is the base and the height, your question isn't full. I'll answer this after I get this information ;)
Answer:
draw a graph and mark the point as (0,7) on the y-axis upper half since its positive.
from there the slope is rise 1 and run 2. meaning from point 7, you go up one, and slide two to the right and mark the next point and keep doing so till you have 3-5 points
