Answer:
4.67 m/s
Step-by-step explanation:
The equation of continuity for an incompressible fluid is A1v1 = A2v2 where A represents area and v is velocity of the fluid.
If we let the values with subscript 1 be those inside the hose and 2 be those at the nozzle then the question can be solved this way

Answer:
a. 1/20 liters in each glass.
b. 50 ml in each glass.
Step-by-step explanation:
a. To find how many liters are in each glass, you have to divide the 1/4 liters by 5 glasses, because the water is poured equally.
Using the division properties of fractions:
b. Use the rule of three to convert from liters to milliliters.
Now, multiply 1/20 l by 1000 ml and divide by 1 l to obtain x.

Answer:
The second one: r x-axis. R 90(x,y)
Step-by-step explanation:
You can see that from ABC to A'B'C', it's rotated a positive 90 degrees. then, from A'B'C' to A"B"C", reflected across x-axis. and when writing the transformation, it goes by last to first. that's why the R 90 comes first.
