So many answers possible.

Let us take, by numbers they mean integers.

Now, the product of 379 and 8 is 3032.

Clearly, on the number line, this number is between the numbers 3031 and 3033.

Hence, the exact product of 379 and 8 is between the pair of numbers 3031 and 3033.

Hope this makes sense.

For simple interest, the interest for each year is calculated on the initial principal itself.
So, for a period of 3 years, the total interest will be

So the total amount at the end of the period

Final answer:

To find the measure of one interior angle of a square, divide the total sum of interior angles, 360 degrees, by the number of angles in a square, which is four. The resulting equation is x = 360° ÷ 4, revealing that each angle measures 90 degrees.

Explanation:

The question asks us to write an equation to describe the measure of one interior angle of a square given that the sum of interior angles of a square is 360 degrees.

A square has four equal interior angles. To find the measure of one angle, we can divide the total degrees by the number of angles.

We can set up the equation as follows: Let x be the measure of one interior angle of a square. Then we write the equation x = 360° ÷ 4. When we calculate it, x equals 90 degrees, which means each interior angle of a square is 90 degrees.

Find out the how much string will Mellisa have left over .

To prove

Let us assume that the  string will Mellisa have left over be x .

As given

Melissa needs 3.87 feet of string to use as a border for her poster.

Melissa finds a piece of string that is 4.25 feet long.

Than the equation is write in the form

x = 4.25 - 3.87

x = 0.38 feet

Therefore the  string will Mellisa have left over be  0.38 feet .

Hence proved

The length of string Mellisa will have left over is 0.38 feet

From the question,

We are to determine how much string Mellisa would have left over.

From the given information

Melissa needs 3.87 feet of string to use as a border for her poster.

Then,

She finds a piece of string that is 4.25 feet long.

That means,

From the piece of string that she found, she will use 3.87 feet out of the 4.25 feet.

∴ The length of string Mellisa will have left is = 4.25 feet - 3.87 feet

The length of string Mellisa will have left is = 0.38 feet

Hence, the length of string Mellisa will have left over is 0.38 feet

To estimate the product of 27.64 and 3, round both numbers to the nearest whole number, then multiply them together.

To estimate the product of 27.64 and 3, you can round both numbers to the nearest whole number. So, 27.64 is approximately 28 and 3 is still 3. Then, multiply 28 by 3 to get an estimated product of 84.

X = number of turkey sandwiches

Y = number of steak sandwiches

X   + Y    = 925 total sandwiches sold

4X + 6Y = 4524 dollars made

-4(X + Y = 925)

-4X + (-4Y) = -3700

 4X +  6Y    = 4524

           2Y    = 824

Y = 412

X + Y = 925

X + 412 = 925

Visualize 4 sets of circles: Each set consists of 2 large blue circles, each containing 2 smaller green circles. In total, there are 4 large blue circles and 8 smaller green circles, representing the result of multiplying 4 by the inner parenthesis (2x2).

Visualizing 4x(2x2) with Circles:

Representing the Inner Parenthesis (2x2):

Imagine two blue circles, side-by-side.

Inside each blue circle, draw two smaller green circles, also side-by-side.

This group of circles (two large blue circles, each containing two smaller green circles) represents the part inside the parenthesis, "2x2."

Multiplying by 4:

Imagine replicating the entire group of circles from step 1 four times.

You now have a total of four groups, each containing two blue circles with two green circles inside each.

Visualization Summary:

You should have a total of 16 circles:

4 large blue circles.

8 smaller green circles (2 inside each blue circle).

These circles are grouped into 4 sets, representing the multiplication of the entire parenthesis (2x2) by 4.

Three-dimensional objects can grow from both one-dimensional and two-dimensional objects when subjected to thermal expansion, which causes areas and volumes, as well as lengths, to increase with temperature.

A three-dimensional object can grow or expand from two-dimensional objects, such as areas (length and width), as well as from one-dimensional objects, such as lengths. When considering thermal expansion in two and three dimensions, it is important to understand that unconstrained objects expand in all dimensions: their areas (two-dimensional) and volumes (three-dimensional), as well as their lengths (one-dimensional), increase with temperature.

For example, if we have a metal plate (a two-dimensional object) with a circular hole in it and we increase the temperature, the area of the plate including the circular hole will increase (Figure 13.11 (a)). Similarly, if we have a solid metal block (a three-dimensional object), its volume will increase with temperature (Figure 13.11 (c)).

The thermal expansion process is explained by the fact that, as temperature increases, the atoms or molecules making up a material move farther apart, causing expansion. This is true for both holes and solid parts of a material, they both grow larger with increased temperature. Therefore, all one-dimensional, two-dimensional, and three-dimensional aspects of an object expand proportional to the increase in temperature.

To convert 75.2 inches to centimeters, multiply it by the conversion factor of 2.54 cm per inch. 75.2 inches is approximately 191.01 centimeters when rounded to the nearest hundredth.

To convert inches to centimeters, you need to use the conversion factor 2.54 cm = 1 inch. The given measurement is 75.2 inches, and you are asked to convert this to centimeters.

You start by setting up the proportion as follows:

To find x, you multiply 75.2 by 2.54:

75.2 inches * 2.54 cm/inch = 191.008 cm

Then round this off to the nearest hundredth (if necessary) to obtain:

75.2 in. ≈ 191.01 cm

Answer:

40

Step-by-step explanation:

We are given that

A railroad container can hold weight=42,000 pounds

Total number of ovens for ship=90

Weight of each oven=200 lbs

Weight of each freezer=600 pounds

We have to find the number of freezer can be shipped in the container.

Let x be the number of freezer can be shipped in the container.

According to question

[tex]42000=90(200)+600x[/tex]

[tex]42000=18000+600x[/tex]

[tex]600x=42000-18000[/tex]

[tex]600x=24000[/tex]

[tex]x=\frac{24000}{600}=40[/tex]

Hence, 40 freezer can be shipped in the container.
