photoshop1234 [79]

Answer: 20%

Step-by-step explanation:

The 150 students in the marching band and 30 of the students play the trumpet. To get the percentage of students that play the trumpet, we divide 30 by 150 and then multiply by 100. This can be written as:

= 30/150 × 100

= 0.2 × 100

= 20%

The percentage of students that play the trumpet is 20%

weqwewe [10]

Answer:

2=k^1/x

3=k^1/y

12=k^1/z.......we get...

(atq)------k^1/x=k^1/y=k^1/z

(*a^m=b^m......b=a)

~1/x=1/y=1/z

1/z=1/y+1/x×2

(12=3+2×2)

1/z=1/y+2/x.....proved

9. All the students in the sixth grade either walk home or take the bus home after scho

timurjin [86]

There are 250 students in sixth grade

Solution:

Given that, All the students in the sixth grade either walk home or take the bus home after school

From given,

Number of students walk home = 170

Let "x" be the total number of students in school

32% of the students take the bus

Thus, 32 % of "x" takes bus

To find: total number of students in school

Total students = Number of students walk home + number of students takes bus

$x = 170 + 32 \% \times x\\\\x = 170 + \frac{32}{100} \times x\\\\x = 170 + 0.32x\\\\x - 0.32x = 170\\\\0.68x = 170\\\\x = 250$

Thus there are 250 students in sixth grade
