Answer:
9 scarves.
Step-by-step explanation:
We have been given that the number N of scarves Ariana can make is inversely proportional to the area A of each scarf.
We know that equation of two inversely proportional quantities in in form
, where, k is constant of variation and y is inversely proportional to x.
Let us find constant of variation using our given information.




Now, we will substitute
in our equation to solve for N.


Therefore, Ariana can make 9 scarves.
1st integer: x
2nd integer: x+2
Multiply them: x(x+2)=440
X^2+2x-440=0
Use the quadratic formula
x=-22 or x=20
Since x must be a positive integer number, x=20.
Answer:
1st: 20.
2nd: 22

Answer:
- B. The constant in the expression is 1/2
Step-by-step explanation:
<u>Given formula for the area of a triangle</u>
<u>Statements to confirm</u>
A. The coefficient of is b.
- False. b is variable, 1/2 is coefficient
B. The constant in the expression is 1/2
C. There is one term in the expression.
- False. There are 3 terms, one constant and two variables
D. There is one variable in the expression.
- False. There are two variables, b and h
<em>Note. </em>
<em>Assumed 1/2 is given in Option B, otherwise all statements are false</em>.
Ratio is a comparison of two values or two quantities.
Fraction is a another form of ratio.
The first term and the second term in the ratios are important.
It should not be changed.
The first quantity value is in first term and the second quantity value is in second term of the ratio.
Ratio and fractions are same.
Example:
The ratio of male to female in the school is 5 : 6.
5 represents male students and 6 represents female students.
The fraction form of the above ratio is
