The total cost of 8 identical pens and 2 identical files is $32 The total cost of 3 such files is the same as the total cost of 4 such pens. Find the cost of each file

Answers

Answer 1

Answer:

$4

Step-by-step explanation:

Given that

total cost of 8 identical pens and 2 identical files is $32

And, the The total cost of 3 such files would be the same  as the total cost of 4 such pens

We need to find out the cost of each file

So let us assume the following things

Pens be x

File be y

Now

8x + 2y = $32 ....(1)

3y = 4x.........(2)

y =  4x÷ 3

Now put the value of y in equation 1

8x + 1.33x = 32

x = $3.55

x = $4

Answer 2

The cost of each file based on the given information is $4

where:

Let the cost of a pen be xLet the cost of a file be y

Simultaneous equation

If the total cost of 8 identical pens and 2 identical files is $32, hence;

8x + 2y = 32

If the total cost of 3 such files is the same as the total cost of 4 such pens, then;

4x = 3y

From the equation

8x + 2y = 32

2(4x) + 2y = 32

2(3y) + 2y = 32

8y = 32

y = 4

Since 6=4x = 3y

4x = 3(4)

4x = 12

x= 3

Hence the cost of each file is $4

Cindy's square-shaped garden has side lengths of x ft. She will plant 5 tulip bulbs per square foot. Write a function g to model the number of bulbs she should plant. How many bulbs will she plant if the garden has a side length of 8 feet? for this problem what is the function we need to write g(x)=?

Answers

Answer:

The total number of bulbs are "320 bulbs".

Step-by-step explanation:

According to the question,

The square garden's side length,

x = 8 feet

Number of tulip bulbs she plant,

= 5

Now,

As per the question, the area of square will be:

⇒ [tex]A=x^2[/tex]

       [tex]=(8)^2[/tex]

       [tex]=64[/tex]

hence,

The total number of bulbs will be:

⇒ [tex]n=A\times 5[/tex]

       [tex]=64\times 5[/tex]

       [tex]=320 \ bulbs[/tex]

Thus the above is the correct solution.

Find the volume of the composite solid. Round your

Answers

Answer:

226.19 [tex]cm^{3}[/tex]

Step-by-step explanation:

Vol. of cone = Bh/3   where B is the area of the base(circle) and h is the height of the cone.

r = 3   h = 3

V = [tex]\frac{\pi *3^{2}*3 }{3}[/tex] = 9π

Vol. of the cylinder = Bh   where B is the base(circle) and h is the height of the cylinder.

r = 3   h = 10 - 3 = 7

V = [tex]\pi *3^{2} * 7[/tex] = 63π

Total volume = 9π + 63π = 72π = 72(3.1416....) = 226.19

 

Volume is a three-dimensional scalar quantity. The volume of the composite figure will be 226.194cm³.

What is volume?

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

The volume of the composite solid is the sum of the slanted cylinder and the cone. Therefore, the volume will be,

Volume = Volume of cone + Volume of slant cylinder

             = [(1/3)πr²h] + [πr²H]

             = [(1/3)×π×(3)²×3] + [π×(3)²×7]

             = 28.274 cm³ + 197.920 cm³

             = 226.194 cm³

Hence, the volume of the composite figure will be 226.194cm³.

Of the boys 8 said yes and 5 said no

8 + 5 = 13 so she asked a total of 13 boys

she asked 14 girls and 13 boys

14 + 13 = 25 so she asked a total of 25 people

Out of the 25 people she asked 13 of them were boys

So 13 out of 25 people we boys

Which expression shows the quotient of two terms where one of the terms includes the coefficient of 8?

Answers

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete; So, I will solve generally

Required

Quotient of two terms where 1 has a coefficient of 8

The quotient (Q) of a and b can be represented as:

[tex]Q = \frac{a}{b}[/tex]

Where a and b are the terms

For a or b to have a coefficient of 8, then a or b must be

[tex]a\ or\ b = 8x[/tex]

Where x is the variable

So, the quotient can be expressed as any of:

[tex]Q = \frac{8x}{y}[/tex]

[tex]Q = \frac{z}{8i}[/tex]

[tex]Q = \frac{24b}{8c}[/tex]

As long as one of the terms has a coefficient of 8
