20 10
Answer:
The Inverse variation says that:
,
then the equation is of the form:
or
Here, r represents the number of roses and w represents the number of weeds.
As per the statement:
The number of roses (r) in a garden increases when the number of weeds (w) decreases.
by definition of inverse variation:
....[1]
From the given table:
take any points
r = 20 and w = 10 then;
Substitute in [1] we have;
Simplify:
k = 200
The equation becomes:
We have to find the number of roses when there are 5 weeds.
⇒w = 5
then;
Divide both sides by 5 we get;
r = 40
Therefore, the number of roses are 40 when there are 5 weeds.
The fraction of students in the class who are men can be calculated by dividing the number of men by the total number of students in the class. Given that there are 18 men in a class of 32 students, the fraction of men in the class is 9/16.
This question is dealing with the concept of fractions in mathematics. From the information given, we know that there are 32 students in the class and 18 out of those are men. To find the fraction of the class that is men, we divide the number of men by the total number of students in the class. This can be expressed as follows:
Number of men / Total number of students = Fraction of the class that are men.
By substituting the given figures into the formula we get:
18 / 32 = 9/16.
Therefore, 9/16 of the students in the class are men. This fraction can be further simplified by dividing both the numerator and denominator by the greatest common divisor.

(solving quadartc equations by factoring)
Answer: He paid $ 4836 in taxes.
Step-by-step explanation:
Here, the total value of the house = $ 93,000
And, the amount on which municipal taxes imposed = 80% of the value of house
= 80% of 93000
= 0.8 × 93000
= $ 74,400
Now, the tax rate is $65 per thousand,
⇒ ,
⇒
⇒
Thus, he paid $ 4836 in taxes.
Answer:
6760
Step-by-step explanation:
80% x 93000 = 74400
74.4 x 65 = 6760
