Answer:
"statement 1: The number of boys at the school is 
of the number of girls." is true.
Step-by-step explanation:
Given:
Ratio of Number of boys to the number of girls = 4 : 5
Total number of students = 270
To find:
Number of boys in terms of number of girls = ?
Solution:
As per given statement,
Let, Number of boys = 
Let, Number of girls = 
Total number of students = Number of boys + Number of girls = 270
Therefore, number of boys = 4 
30 = 120
And, number of girls = 5 30 = 150
As per Statement 1:
Finding of the number of girls:
= Number of boys.
Finding 
of the total number of students:
= Number of boys.
Number of boys is equal to of total number of students.
So, "statement 1: The number of boys at the school is of the number of girls." is true.

120+12+10
Answer:
r= -6
Step-by-step explanation:
<u>Assuming we are finding r,</u>
- | -2r-1| = 11
-( 2r + 1 ) = 11
-2r -1 = 11
-2r = 12
r= -6

The answer is 296,000,000.
Step-by-step explanation:
step 1. perpendicular lines have negative reciprocal slopes
step 2. perpendicular to m = 1/3 is the slope m = -3/1 or m = -3
step 3. a line through (3, 2) with m = -3 is y - 2 = -3(x - 3)
step 4. y - 2 = -3x + 9
step 5. y = -3x + 11.
