What do the parts of the expression of 48 is represent

Answer: 43 small tanks

Step-by-step explanation:

First, take 900 - 212 = 688 fish in small tanks

Then take 688 divided by 16 fish in each tank = 43

So there are 43 smaller tanks

Taking into account the definition of a system of linear equations, the price of one order of chicken nuggets and one chicken sandwich is $2.98 and $4 respectively.

A system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.

A solution to a system is an assignment of values to the unknowns that makes each of the equations true. Solving a system means finding all the solutions of the system.

In this case, a system of linear equations must be proposed taking into account that:

You know:

The system of equations to be solved is

2x +3y= 17.96

4x + 2y= 19.92

It is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.

In this case, isolating the variable "y" from the first equation:

3y= 17.96 -2x

y= (17.96 -2x)÷3

y= 17.96÷3 - 2÷3x

y= 449/75 - 2/3x

Substituting the expression in the second equation:

4x + 2×(449/75 - 2/3x)= 19.92

Solving:

4x + 2×449/75 - 2×2/3x= 19.92

4x + 898/75 - 4/3x= 19.92

4x - 4/3x= 19.92 - 898/75

8/3x= 596/75

x= 596/75÷ 8/3

x= 2.98

Remembering that y= 449/75 - 2/3x, you get:

y= 449/75 - 2/3×2.98

y= 4

Finally, the price of one order of chicken nuggets is $2.98 and the price of one chicken sandwich is $4.

The area of the pyramid = 340 sq. inches

The area of a square pyramid= b^2+ 2.b.s

                                                  = 10^2 + 2*10*12

                                                  = 340 sq. inches

We can also find out the are by finding area of each sides

Area of square = 10*10 = 100 sq. inches

Area of triangle= 1/2( 12*10)

                           = 60

Area of four triangles = 4*60

                                    = 240

Total surface area = 240+100

                                = 340 sq. inches

Hence the total surface area is 340 sq. inches

Proportion:

A proportion is an equation between two ratios or rates that is useful in solving for a single unknown.

We have given that,

It takes 250 bricks to build a 15 ft high wall. Let us consider x bricks , is needed for a 75 ft high wall, use the ratio given for a 15 ft high wall and equate it to the ratio for the unknown number of bricks for a 75-ft high wall.

In making proportions, make sure that the rate on one side has the same units as the rate on the other as shown :

x/75 = 250/15

=> 15 × x = 250 ×75

=> x = 250×75/15

=> x = 1250

What is a tangent line?

The straight line that "just touches" the curve at a particular location is known as the tangent line (or simply tangent) to a plane curve in geometry. It was described by Leibniz as the path connecting two points on a curve that are infinitely near together.  A straight line has a slope of f'(c), where f' is the derivative of f, and is said to be tangent to a curve at a point x = c if it passes through the point (c, f(c)) on the curve. Space curves and curves in n-dimensional Euclidean space have a similar definition.

[tex]$$\begin{aligned}& f^{\prime}(x)=\frac{\mathrm{d}}{\mathrm{d} x}\left[x^3-2 x\right] \\& f^{\prime}(x)=\frac{\mathrm{d}}{\mathrm{d} x}\left[x^3\right]-\frac{\mathrm{d}}{\mathrm{d} x}[2 x] \quad \text { Sum } / \text { Rest rule } \\& f^{\prime}(x)=3 x^{3-1}-2 \quad \text { Power rule } \\& f^{\prime}(x)=3 x^2-2 \\&\end{aligned}$$[/tex]

Now finding tangent for a=-1,

The width value if A rectangle has an area of 24 cm² are 8, 48, 0.5, 4, and non-defined.

The measurement that expresses the size of a region on a plane or curved surface is called an area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.

Given:

A rectangle has an area of 24 cm²

The function of the area can be written as,

F(A) = l × b, b = A / l

Put l = 3

then b = 24 / 3 = 8 cm

Put l = 0.5

then b = 24 / 0.5 = 48 cm

Put l = 48

then b = 24 / 48 = 0.5 cm

Put l = -6

then b = 24 / -6 = -4 cm

Put l = 0

then b = 24 / 0  = non defined

Therefore, the width value if A rectangle has an area of 24 cm² are 8, 48, 0.5, 4, and non-defined.

The bacteria culture has an initial size of 79.7409

Given,

The count in a bacteria culture;

After 10 minutes is 400

After 30 minutes is 2000

Assume that the count grows exponentially;

We have to find the initial size of the culture;

Here,

The growth of population can be calculated using;

P = P₀ (1 + r)^t

Here,

Count of bacteria, P = 400 and 2000

Time period, t = 15 and 30

Initial size =  P₀

So,

400 = P₀ × (1 + r)¹⁰

2000 = P₀ × (1 + r)³⁰

Take P₀ common.

Then,

400/(1 + r)¹⁰ = 2000/(1 + r)³⁰

(1 + r)³⁰/ (1 + r)¹⁰ = 2000/400

(1 + r)¹⁰ = 5

1 + r = 1.175

r = 0.175

Now,

The value of P₀ should be determined from the above equation;

That is,

400 = P₀ × (1 + 0.175)¹⁰

P₀ = 400/ (1 + 0.175)¹⁰

P₀ = 79.7409

Therefore,

The initial size of the bacterial culture is 79.7409

The domain of a function is the set of all possible input values (x-values).

From inspection of the given graph:

Therefore, the domain is all values of x except x = 1:

The range of a function is the set of all possible output values (y-values).

From inspection of the given graph:

Therefore, the range is all values of y except between -2 and 2:

A function is a special type of relationship where each input (x-value) is related to exactly one output (y-value).

From inspection of the graph, as the two points where x = 1 are not included, each value in the range (y-values) corresponds to exactly one value in the domain, and so it is a one-to-one function.

A linear equation is used to prove the mathematical result that two linear expressions, or a linear expression and a constant, are not equivalent.

The mathematical assertion that two linear expressions, or a linear expression and a constant, are not equal is made via a linear equation.

The point-slope form, standard form, and slope-intercept form are the three main types of linear equations.

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included.

The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

A mathematical equation must take the form y=mx+b in order to be classified as a linear function (in which m is the slope and b is the y-intercept).

Therefore, a linear equation is used to prove the mathematical result that two linear expressions, or a linear expression and a constant, are not equivalent.

A compound shape is made up of two or more basic shapes.

From inspection of the given compound shape, we can see that it is made up of two rectangles.

[tex]\boxed{\begin{minipage}{4 cm}\underline{Area of a rectangle}\\\\$A=w \cdot l$\\\\where:\\ \phantom{ww}$\bullet$ $w$ is the width. \\ \phantom{ww}$\bullet$ $l$ is the length.\\\end{minipage}}[/tex]

Dimensions of the smaller rectangle:

Dimensions of the larger rectangle:

Therefore, the equation for the area of the compound shape is:

[tex]\begin{aligned}\implies \textsf{Area}&=x \cdot 4 + x \cdot (2x+3)\\&=4x+x(2x+3)\\&=4x+2x^2+3x\\&=2x^2+7x\end{aligned}[/tex]

The wave function that satisfies wave equation is D(x,t) = A cos(kx + ωt) that is option C is correct.

This wave function satisfies the wave equation because it can be rewritten as:

D(x,t) = A cos(kx) cos(ωt) - A sin(kx) sin(ωt)

And the left-hand side of the wave equation is simply the sum of the second derivatives of the two cosine and sine functions with respect to x, while the right-hand side is the product of the second derivative of the cosine function with respect to t and the second derivative of the sine function with respect to t.

For the transverse velocity of a particle at point x, the function is given by:

v(x,t) = -Aω sin(kx) cos(ωt) - Ak cos(kx) sin(ωt)

And for the transverse acceleration, the function is given by:

a(x,t) = -Aω^2 cos(kx) cos(ωt) + Ak^2 sin(kx) sin(ωt)

These functions can be derived by taking the first and second derivatives of the wave function with respect to time.
