Density is a material's intrinsic (intrinsic) property that depends on how much it occupies a particular space and possibly on temperature.

Density is expressed in units of mass divided by volume. The International Standard Unit (SI) is the kilogram per cubic meter ("cube") or kg/m3. Some commonly used density units are grams per cubic centimeter, or we can also express it as g/cm3; it is more widely used in laboratories.

Mass and volume are related by a term called density.

The formula gives the relation between the mass and the density of an object:

Density = Mass/ Volume

We can extract the desired quantity from this formula, and here it is mass, so,

Mass = Density x Volume

So, by using the above information, 100 cm^3 bar weighs 1930gm.

Answer:

13 hours to earn the same amount and 14 hours to earn more

Step-by-step explanation:

The weight of the bag she brings home is; D: Multiply (5,000,000 x 6.7 x 10^-7) = (5 x 10^6) x (6.7 x 10^-7) = (5 x 6.7) x (10^(6 + - 7)) = 33.5 x 10^-1 = 3.35 kg

We are told that Maria wanted to bring back 5 million kg of sand from her trip to the beach. Thus;

Amount of sand she wanted to bring out = 5,000,000 kg = 5 * 10⁶ kg

Now, we are told that each grain of sand weighs 6.7 * 10⁻⁷ kg. Thus, the total amount of sand she brings home is;

(5 * 10⁶) * (6.7 * 10⁻⁷) = (5 * 6.7) * (10⁶ ⁻ ⁷) = 33.5 * 10⁻¹ = 3.35 kg

Thus, the correct answer is; Multiply (5,000,000 x 6.7 x 10^-7) = (5 x 10^6) x (6.7 x 10^-7) = (5 x 6.7) x (10^(6 + - 7)) = 33.5 x 10^-1 = 3.35 kg

Answer: p=178/3 degrees

Step-by-step explanation:

Based on the problem, I THINK these three angles add up to 180 degrees

(p-43)+(p)+(p+45)=180

p-43+p+p+45=180

p+p+p-43+45=180

3p+2=180

3p=178

aₙ = 5*(1/5)^(n - 1) is the explicit formula of the sequence.

What is Sequence and example ?

The recursive relation for a geometric sequence is

aₙ = aₙ₋₁*R

where R is the common ratio.

We could write this in a general form as:

aₙ = a₁*(R)^(n - 1)

where a₁ is the first term of the sequence.

In this case we know that:

R = 1/5

And that:

a₆ = 1/625

Then we can replace these values in the above relation to get:

a₆ = (1/625) = a₁*(1/5)^(6 - 1) = a₁*(1/5^5) = a₁*(1/3125)

1/625 = a1*(1/3125)

(3125/625) = a1 = 5

Then the formula will be:

aₙ = 5*(1/5)^(n - 1)

The simplified form of given complex fraction is (1/xy - 1/y²) / (1/x²y - 1/xy²) =  x

In this question,

we have been given a fraction 1/x y - 1/y² / 1/x²y - 1/x y²

We need to simplify given complex fraction.

First we simplify numerator.

1/x y - 1/y²

= y² - xy / xy³

= y(y - x) / xy³

= y - x / xy²

Now we simplify denominator.

1/x²y - 1/x y²

= xy² - x²y / x³y³

= xy(y - x) / x³y³

= y - x / x²y²

So given fraction would be,

1/x y - 1/y² / 1/x²y - 1/x y²

= y - x / xy² / y - x / x²y²

= (y - x / xy²) × (x²y² / y - x )

= x²y² / xy²

= x

Therefore, the simplified form of given complex fraction is 1/x y - 1/y² / 1/x²y - 1/x y² = x

Explanation:

Let's find the width of the microscope slide in meters.

1000 mm = 1 m

1 mm = 1/1000 m

1 mm = 0.001 m

50*(1 mm) = 50*(0.001 m)

50 mm = 0.05 m

50 mm = 5 × 10^(-2) m

The microscope slide is 5 × 10^(-2) meters across. Divide this over the width of one hair.

5 × 10^(-2) ÷ 2.5 × 10^(-5)

(5/2.5) × 10^(-2 - (-5) )

2 × 10^(-2 + 5)

2 × 10^3

This converts to the number 2000. So we could have 2000 strands of hair side by side.

Answer:

(A)  2 * 10^3.

Step-by-step explanation:

50 millimeters = 0.05 m

= 5 * 10^-2 meters.

So, we divide this by the diameter of 1 hair:

= (5 * 10^-2) /  (2.5 * 10 ^ - 5)

= (5/2.5) * (10/^-2 / 10^-5)

= 2 * 10^(-2-(-5))

= 2 * 10^3.

The domain and range of the give relation can be determined by listing the x values for the domain and listing the y values from the range. If each x corresponds to only one y, it is a function.

Domain of a relation refers to all the input values of the relation. Hence, domain is the set of all x coordinates. In the given data, the domain is:

{-3, -1, 0, 1, 2}

Range of a relation refers to all the output values of the relation. Hence, range is the set of all y coordinates. In the given data, the range is:

{4, 2, 0, -2}

In order for a relation to be a function, each x must correspond to only one value of y i.e., an x   has one y value. For example, for a relation x = 4 and y = 1,2, hence it is not a function.

In our relation, each x value has only one y value, it is a function.

Mapping the relation can also give us the answer in a simpler way.

As there is one arrow leaving each x value, it is a function. (If two arrows are leaving an x value it is not a function.  

Hence, for the relation given, Domain: {-3, -1, 0, 1, 2}, Range: {4, 2, 0, -2} and it is function.

A system of equation can be solved using:

The given system of equations:

2x + 4y = -8  ............   (1)

-5x + 4y = 6  .............. (2)

Since the coefficients of y is the same in both equations, variable y will be immediately cancelled out if we use elimination method.

Substract equation (2) from equation (1)

2x + 4y = -8

-5x + 4y = 6 –

7x         = -14

  x         = -2

Substitute x = -2 into equation (1):

2x + 4y = -8
