Answer: 0.75,
The constant of proportionality is the ratio between two directly proportional quantities.
The cost of book changes but the lost book fee charge remains constantper book i.e.0.75
Step-by-step explanation:
Given: Let x be the cost of her book (in dollars).
Since, her school charges a lost book fee equal to 75% of the cost of the book.
Then, the the lost book fee=75% of x
Since 75% =0.75
Thus, the the lost book fee=$0.75x
The cost of book changes but the lost book fee charge remains constant per book i.e.0.75
Sarah received a notice stating that she owed the school $60 for he lost book.
The the lost book fee=
Answer:
Step-by-step explanation:
Nick's age = x years
Lina's age =3*x = 3x
After 6 years,
Lina's age = 3x + 6
Nick's age = x + 6
3x + 6 = 2*(x+6)
3x + 6 = 2*x + 2*6
3x + 6 = 2x + 12 {Subtract 6 form both sides}
3x +6 - 6 = 2x + 12 - 6
3x = 2x + 6 {subtract 2x from both sides}
3x - 2x = 2x + 6 - 2x
x = 6
Nick's age = 6 years
Lina's age =3*6 = 18 years

Answer:
22
Step-by-step explanation:
x-1 is a midsegment.
According to the Triangle midsegment theorem, x-1 is half of the third side (42)
x-1 = 42/2
x-1 = 21
x= 22
or
2x-2=42
2x=44
x=22

Answer: The ratio 16:12 describes the ratio of the number of students who play the viola to the students who play the clarinet.
Step-by-step explanation:
Given : Number of students who play the clarinet= 12
Number of students who play the viola=16
We know that ratio of A to B is represented by A:B.
Since, the number '12' is representing " students who play the clarinet" and number '16' is representing " students who play the viola"
So , the ratio 16:12 describes the ratio of the number of students who play the viola to the students who play the clarinet.
