Given:

44 cu. cm of wire is drawn into a wire of diameter 2 mm.

To find:

The length of the wire.

Solution:

We know that,

1 cm = 10 mm

1 cu. cm = 1000 cu. mm

We have, a wire of cylindrical shape.

Volume of the wire = 44 cu. cm

                                = 44000 cu. mm

Radius of the wire = 2 mm

Volume of a cylinder is:

[tex]V=\pi r^2h[/tex]

Where, r is the radius and h is the height.

Putting V=44000, [tex]\pi=\dfrac{22}{7}[/tex] and r=2, we get

[tex]44000=\dfrac{22}{7}\times 2^2\times h[/tex]

[tex]44000\times \dfrac{7}{22}=4h[/tex]

[tex]14000=4h[/tex]

Divide both sides by 4.

[tex]\dfrac{14000}{4}=h[/tex]

[tex]3500=h[/tex]

Therefore, the length of the wire is 3500 mm or 350 cm.

Answer:

8n + 8

Step-by-step explanation:

We already know that n is the unknown number. Product means multiplying, so you multiply 8 by the unknown number. More than means adding, so you add 8 to the product of 8n.

Answer:

The answer is 12860082/100000000000

The fraction form of the expression is -1/7776.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

[tex](-1/6)^5[/tex]

This can be simplified as,

= [tex]\frac{(-1)^5}{6^5}[/tex]

= -1/7776

Thus,

The fraction form of the expression is -1/7776.

Answer:

Rate = 4%

Step-by-step explanation:

Simple interest = (principal × rate × time) / 100

Principal = $399.00

Rate = ?

Time = 2 years

Interest = $31.92

Simple interest = (principal × rate × time) / 100

31.92 = (399 * x * 2) / 100

31.92 = 798x / 100

Cross product

31.92 * 100 = 798x

3192 = 798x

x = 3192 / 798

x = 4%

Rate = 4%

Answer:

530.66

Step-by-step explanation:

The computation of the area of the cross section is shown below

Given that

Volume = 9208 m^3

Now let us assume the radius be r

So volume = 4 ÷ 3 πr^3

9202.8 × 3 ÷ 4π = r^3

27,608.4 ÷ 4 × 3.14 = r^3

27,608.4 ÷ 12.56 = r^3

2,198.12 = r^3

r = 13

Now the area of the cross section is

= πr^2

= 3.14 × (13)^2

= 530.66

Answer:

25% increase

Step-by-step explanation:

Just do 250000/200000 you will find 1.25

And the one is the base 200000 and convert .25 to percentage, which is 25%

Brainliest maybe?

Answer:

25% or .25

Step-by-step explanation:

fist find the number it increased by minus 250000 from 200000

250000 - 200000 = 50000

then divide the increase by the original

50000/200000 = .25 or 25%

The equation that can be solved to find the number of nails in each box =

5x = 460

The number of nails in each box = 92 nails

Step-by-step explanation:

A carpenter bought 5 identical boxes of nails. She used 25 nails for a project and now has 435 nails left. Which equation can be solved to find the number of nails in each box.

Let the number of nails in each box be represented by x

Therefore our Equation =

5x = 25 + 435

5x = 460

Solving for x

5x/5 = 460/5

x = 92 nails

Therefore, the number of nails in each box = 92 nails

Answer:

It would last for 3.2 days.

Step-by-step explanation:

100 men = 8 days

10 men = 0.8 days

60 men = 0.8 x 6 = 4.8 days

Now you subtract the days of 100 men and 60 men

8 - 4.8 = 3.2 days

Given:

To find:

Answer:

Let's assume that the length is 2x and the width is 1x.

We know that the formula to find the perimeter of a rectangle is as follows:

Perimeter = 2 × (Length + Width)

Substituting the values that we have, into the formula above,

84 = 2 × (2x + 1x)

84 = 2 × 3x

84/2 = 3x

42 = 3x

x = 42/3

x = 14

Since we know the value of 'x', let's use it to find the length and the width.

Length = 2x = 2 × 14 = 28

Width = 1x = 1 × 14 = 14

Since we now know the length and the width, let's find the area of the rectangle.

The formula to find the area of a rectangle:

Area = Length × Width

Substituting the values we have into the formula,

Area = 28 × 14

Area = 392

Therefore, the area of the rectangle is 392 square yards.

Hope it helps. :)

Answer:

(a) Leann is incorrect

(b) For every main dish, there are 3 sides

(c) 6 selections

Step-by-step explanation:

See attachment for complete question

Given

Main Dish: Burger (B), Chicken (C), Pasta (P)

Sides: Apple (A), Fries (F)

Solving (a): Is Leann list correct?

From the question, the list is: BA, BF, CA, CF, PA, PF, AB, FB, AC, FC, AP, FP

This list is incorrect because:

AB is the same BA, BF is the same as FB and so on

Solving (b): Number of sides for each Main dish

From the question:

[tex]Main\ dish = 2[/tex]

[tex]Sides = 3[/tex]

This implies that:

For every main dish, there are 3 sides

Solving (c): Total number of selection

In (b), we have:

[tex]Main\ dish = 2[/tex]

[tex]Sides = 3[/tex]

So: the total is:

[tex]Total = Main\ dish * Sides[/tex]

[tex]Total = 2 * 3[/tex]

[tex]Total = 6[/tex]

Answer:

The answer is  A
