Find the approximate side length of a square game board with an area of 174 in2.

The mass of copper in the statue is 46kg.

Ratio of cooper to tin is 23 to 2 and similarly it would be 46 to 4, which adds up to 50. So the mass of cooper in the statue is 46kg.

It is one of the fundamental quantities of physics and a fundamental property of matter. We can define mass as a measure of the amount of matter in a body. The SI unit of mass is the kilogram (kg).

The bit mass  does not change at any time. Only in certain extreme cases, when enormous amounts of energy are given or taken from the body. For example: in a nuclear reaction, a small amount of matter is converted into a huge amount of energy, which reduces the mass of the matter.

For the given equation 2(x-0.1x-2.70)=56.70, the value of x is 7.76

The equals sign is used in mathematical formulas to show that two expressions are equal. The first stage in resolving a variable equation is determining the values of the variables that lead to equality. The variables for which the equation must be solved are known as the unknown variables, while the values of the unknown variables that satisfy the equality are referred to as the equation's solutions. Identity equations and conditional equations are the two types of equations.

Given equation, 2(x-0.1x-2.70) = 56.70

or, 2(0.9x-2.70) = 56.70

or, 1.8x - 5.40 = 56.70

or, 1.8x = 56.70+5.40

or, x = 62.10/1.8 = 7.76

To convert miles per hour to feet per second the conversion factor that wouldn't be used is option d: 1 mi/5280 ft  and 5 miles per hour will be equal to 7.34 feet per seconds.

As per the question statement, we are asked that which of the given conversion factors, will not be used for converting miles per hour to feet per second.

We should be knowing the following values for conversion:

we know, 1 mile = 1.6 km = 5280 feet

and 1 hour = 60 minutes = 3600 seconds.

Now, mi/hr * 1hr/60min * 1min/60sec * 5280ft/mi

Note that units all cancel out leaving only ft/sec

Hence option d : 1 mi/5280 ft is not appropriate for converting mi/hr to ft/sec.

For e.g., 5 miles per hour = 5*5280/3600

5 mil/hr = 7.34 ft/sec

Hence, to convert miles per hour to feet per second the conversion factor that wouldn't be used is option d: 1 mi/5280 ft  and 5 miles per hour will be equal to 7.34 feet per seconds.

If the scale used is 3cm to 100mi, the distances will be larger, because 100 miles is a lot more than 3 centimeters.

A change of scale is what we use to represent large objects (or smaller objects) in diagrams.

They allow us for example to have a big drawing of a cell, or put an area of the size of a country in a A4 piece of paper.

In this case, the change of scale is:

3cm to 100mi

He created models of each of the platonic solids since it is shown in the data that they are connected to the planets' orbits. Kepler fashioned wooden edges to form each of the platonic solids into a frame.

Two of the six planets identified at the time were regarded to be platonic solid cubes. The three-dimensional shape of a cube has 12 edges and 8 corners.

Thus, there are 4 x 2 + 1 edges.

The total number of coins is 24.

Let there be y number of notes in the bag. Then we can write,

On solving we get,

Thus there are 64 notes in the bag.

The angle measures are;

m < 1  = 33°

m < 2 = 57°

It is important to note that complementary angles are defined as pairs of angles that sum up to 90 degrees.

From the information given, we have the angle measures as;

This can be represented as;

m < 1 + m < 2 = 90

Now, let's substitute the values into the equation, we have;

(x + 14) + 3x = 90

expand the bracket, we have;

x + 14 + 3x = 90

collect like terms

4x = 90 - 14

subtract the values

4x = 76

Make 'x' the subject of formula, we get;

x = 76/4

x = 19

Then,

m < 1 = (x + 14) = 19 + 14 = 33°

( 5x + 3 )( 4x - 5 ) is the factorized form of the polynomial 20x² - 13x - 15 using the AC method.

AC Method is simply a method of factoring trinomials in the form ax² + bx + c.

Given the polynomial in the question;

20x² - 13x - 15

Compare to the form ax² + bx + c

To factor, compare to the form ax² + bx + c and rewrite the middle term as a sum of two terms whose product is;

a × c = 20 × -15 = -300

and whose sum is;

b = -13

Now, factor -13 and of -13x

20x² - 13(x) - 15

We know that -13 is the same as 12 - 25

20x² + (12 - 25)(x) - 15

20x² + (12 - 25)x - 15

Apply distributive property

20x² + 12x - 25x - 15

Group the terms

(20x² + 12x) - 25x - 15

Now, factor out the greatest common factor from each group

Answer:

y = 4x - 14

Step-by-step explanation:

The equation of a straight line is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0).

We can calculate the slope with the two given points.  Slope is the Rise/Run between these 2 points:

(4,2) and (6,10)

Rise:  10 - 2 = 8

Run:    6 - 4 = 2

Slope = Rise/Run = 8/2 = 4

m is 4, so we can write:  y = 4x + b

We can find b by entering either of the given points and solving for b.  I'll use (4,2):

y = 4x + b

2 = 4*(4) + b

2 = 16 + b

b = -14

The equation becomes y = 4x - 14
