Answer:
5P5×20P15
Step-by-step explanation:
A school bus has 25 seats, with 5 rows of 5 seats.
15 students from the first grade and 5 students from the second grade travel in the bus.
second-grade students occupy the first row.
The 5 students of second grade are to be seated in 5 seats,this can be done in:
5P5 ways where P is the permutation
Now 15 students from first grade are to be arranged in remaining 20 seats
This can be done in:
20P15 ways
Hence, total ways student can be seated is:
5P5×20P15
First, convert 23% into a fraction.
23% =

Now the expression to determine 23% of 122 is

Answer:
w=120°
x=45°
y=30°
Step-by-step explanation:
AT=PR, AR=PT
Therefore, y=30°
y+45°=x+30°
x=45°
In triangle:
y+30°+w=180°
w=120°
