Answers

Answer 1

Answer:

9/21 & 7/21

Step-by-step explanation:

Answer 2

Equivalent fraction for  [tex]\frac{3}{7}[/tex] and  [tex]\frac{1}{3}[/tex] using 21 using as the common denominator are [tex]\frac{9}{21} ,\frac{7}{21}[/tex].

What are equivalent fraction?

"Equivalent fraction is fraction with different numerator or denominator

that represents the same value or proportion of the whole."

What is common denominator?

"Common denominator is the same denominator of all the fraction"

We have to write an equivalent fractions for [tex]\frac{3}{7}[/tex] and [tex]\frac{1}{3}[/tex]  using 21 as common denominator.

As we know when we multiply [tex]7[/tex] by [tex]3[/tex] to get [tex]21[/tex]

and we have to multiply [tex]3[/tex] by [tex]7[/tex] to get [tex]21[/tex]

⇒[tex]\frac{3}{7}=\frac{3}{7}[/tex]×[tex]\frac{3}{3}=\frac{9}{21}[/tex]

⇒[tex]\frac{1}{3}=[/tex][tex]\frac{1}{3}[/tex]×[tex]\frac{7}{7}=\frac{7}{21}[/tex]

Hence, Equivalent fraction for  [tex]\frac{3}{7}[/tex] and  [tex]\frac{1}{3}[/tex] using 21 as common denominator are [tex]\frac{9}{21} ,\frac{7}{21}[/tex].

Given:

Number of sides = 7

Apothem = 8 meters

Side length = 7.7 meters

To find:

The area of the regular polygon.

Solution:

We know that,

Area of a regular polygon is

[tex]A=\dfrac{1}{2}pa[/tex]        ...(i)

where, p is perimeter and a is apothem.

Perimeter of a regular polygon is the product of number of sides and side length.

[tex]p=7\times 7.7[/tex]

[tex]p=53.9[/tex]

Substituting p=53.9 and a=8 in (i), we get

[tex]A=\dfrac{1}{2}(53.9)(8)[/tex]

[tex]A=(53.9)(4)[/tex]

[tex]A=215.6[/tex]

Therefore, the area of the regular polygon is 215.6 m².

Answer:

take out the a with an equation

The solution of x is y+4b/9a for equation y=9ax-4b

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

The given equation is y=9ax-4b

y equal to nine times of  and x minus four times of b.

We need to solve for x

Add 4b on both sides

y+4b=9ax-4b+4b

y+4b=9ax

Divide both sides by 9a to separate x on RHS

y+4b/9a=x

Hence the solution of x is y+4b/9a for equation y=9ax-4b

Cheddar cheese cost 4.25 per pound. Which equation best represents y, the cost of x pound of cheddar cheese

Answers

Answer:

y = 4.25x

Step-by-step explanation:

Cheddar cheese cost 4.25 per pound . This means the cost of cheddar cheese is 4.25 for every pound in weight. Assuming we put a currency to the value we can say 1 pound of cheddar cheese is equals to 4.25 dollars($4.25). Mathematically, it can be represented as

4.25 is the cost for 1 pound of Cheddar cheese

Let the cost of the equation be y as required from the question.

y = cost of the cheddar cheese

x is the weight value in pounds of the Cheddar cheese.

The equation can be best represented as

y = 4.25x

In the equation above if the amount in pounds is 3 pound . the value will be inputted for x and the cost will be gotten which is y.
