Answer:

[tex] \sf \rho \: = 1.25[/tex]

Step-by-step explanation:

Density, is the substance's mass per unit of volume. The symbol most often used for density is ρ, although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume:

[tex]{\displaystyle \rho ={\frac {m}{V}}} [/tex]

where ρ is the density, m is the mass, and V is the volume.

[tex] \sf \rho = \frac{750}{600} [/tex]

[tex] \sf \rho \: = 1.25[/tex]

Therefore, density is equal to 1.25

The Native American population in state A and B is 282,000 and 94,000 respectively.

Here, we are given that State A's population of Native Americans is three times the Native American population of State B.

Let the Native American population in state B be x

Thus, the Native American population in state A will be 3x

Total Native American population in state A and B = 376,000

Thus, we can get the following equation-

x + 3x = 376,000

4x = 376,000

x = 376,000/ 4

x = 94,000

⇒ 3x = 3 × 94,000

3x = 282,000

Thus, the Native American population in state A and B is 282,000 and 94,000 respectively.

Answer:

13.7 feet

Step-by-step explanation:

The ladder and the building will form a right triangle with the ladder's length is hypotenuse

so if a is the height of the building

c^2 = a^2 + b^2

(15)^2 = a^2 + (6)^2

225 = a^2 + 36

a^2 = 225 - 36 = 189

a = √(189 = 13.7

Answer:

0.25x -12= 18- 0.55x (subtract 0.25x from both sides)

-12= 18 -0.80x (subtract 18 from both sides)

-30= -0.80x (divide each side by -0.80)

x= 37.5 (this is your answer)

The value of x in which the two expressions have the same value is 37.5

Here,

Given that;

Two expressions are,

Expression 1 :   0.25x - 12

Expression 2:   18- 0.55x

We have to find the value of x.

What is Mathematical expression?

A sentence with a minimum of two numbers or variables and at least one math operation is present, is called Mathematical expression.

Now,

The value of x will be find after equating both expressions as;

0.25x - 12 = 18 - 0.55x

Subtract 0.25x from both sides, we get;

- 12 = 18 - 0.80x

Subtract 18 from both side, we get;

- 30 = - 0.80x

Divide each side by -0.80, we get;

x= 37.5

Hence, The value of x in which the two expressions have the same value is 37.5

The integrand is odd.

[tex]f(x) = \dfrac{x^3 + 4x}{x^4 + 5} \implies f(-x) = \dfrac{(-x)^3 + 4(-x)}{(-x)^4 + 5} = \dfrac{-x^3-4}{x^4+5} = -f(x)[/tex]

Answer: 91 crate

Step-by-step explanation:

weight preloaded=

14500

weight per crate=

120

weight capacity=

25500

Method 1 (Unwinding):

weight of all crates=

weight capacity−weight preloaded

=

=

25500−14500

=

11000

number of crates=

weight per crate

weight of all crates

=

=

11000

=

91.666666...

Technically, 91.666666... is the greatest number of crates that can be loaded into the shipping container. But you can't load part of a crate. The true maximum is the highest whole number below 91.666666..., which is 91.

Method 2 (Algebra):

c= number of crates

The greatest weight means less than 25500 kilograms can also be loaded into the container, so we will use the \leq≤ ("less than or equal to") symbol:

120c+14500≤

25500

−14500=

−14500

\color{red}{120}c\leq

120c≤

11000

120

11000

Divide both sides by 120

c ≤ 91.666666...

Technically, 91.666666... is the greatest number of crates that can be loaded into the shipping container. But you can't load part of a crate. The true maximum is the highest whole number below 91.666666..., which is 91.

Answer:

n = 3.8

Step-by-step explanation:

First, we would distribute 0.3 with n and 1.5.

0.3(n - 5) = 0.4 - 0.2n → 0.3n - 1.5 = 0.4 - 0.2n

Next, we can move the number with the variable to one side.

0.2n + 0.3n - 1.5 = 0.4 - 0.2n + 0.2n → 0.2n + 0.3n - 1.5 = 0.4

(Because we added 0.2n to the negative 0.2n on the right side, it cancels it out)

We can also move 1.5 to the right side of the equation as well.

0.2n + 0.3n - 1.5 + 1.5 = 0.4 + 1.5 → 0.2n + 0.3n = 0.4 + 1.5

Then, we combine like terms

0.2n + 0.3n = 0.5n & 0.4 + 1.5 = 1.9 → 0.5n = 1.9

Finally, we divide both sides by 0.5.

n = 3.8

Answer:

$5

Step-by-step explanation:

We can solve this using a system of linear equations. The equations are written like this:

3v + 9d = 75

5v + 10d = 100 (25 more than Dawn's total is 100)

V represents video games and d represents DVDs.

Let's isolate a variable, I'm going to isolate v in the first equation:

3v = -9d + 75

v = -3d + 25

Now that we isolated v we can plug it in to the second equation:

5(-3d + 25) + 10d = 100

-15d + 125 + 10d = 100

-5d + 125 = 100

-5d = -25

d = 5

Therefore, each DVD cost $5.

Check:

3v + 9(5) = 75

3v + 45 = 75

3v = 30

v = 10

5(10) + 10(5) = 100

50 + 50 = 100

100 = 100
