Using system of linear equations, the law firm employed  7 associate and 9 partners

The system of linear equations can be defined as a set of two or more linear equations that have the same variables. Linear equations can be said as the equations of the first order, i.e., the highest power of the variable is 1. Linear equations can have one variable, two variables, or three variables. Thus, we can write linear equations with n number of variables.

In this question, we have to write out two equations and solve for the unknown variable.

let;

x + y = 16 ...eq(i)

400x + 1000y = 11800 ...eq(ii)

From equation 1

x = 16 - y ...eq(iii)

Put eq(iii) into equation (ii)

400(16 - y) + 1000y = 11800

6400 - 400y + 1000y = 11800

6400 + 600y = 11800

600y = 11800 - 6400

600y = 5400

y = 5400 / 600

y = 9

Put y = 9 in equation (i)

x + 9 = 16

x = 16 - 9

x = 7

a ball is dropped from a height of 20 feet. each time it drops h feet, it rebounds 0.89h feet, 343.63 feet the total distance traveled by the ball.

The length of the line connecting any two places is known as their distance from one another. Subtracting the different coordinates will reveal the distance if the two locations are on the same horizontal or vertical line.

h₁ = 20 feet = h

h₂ = 0.89h

h₃ = 0.89²h

h₄ = 0.89³h

...........................

h(n) = 0.89ⁿh

Therefore, total distance travelled = 20 + 2 (0.89h + 0.89²h + 0.89³h +.....)

                                                        = 20 + 2h (0.89 + 0.89² + 0.89³ +.....)

Sum of (h.p)∞ = a/ (1-r)

Where, a = first term = 0.89

r = common ratio = 0.89

total distance travelled = 20 + 2 × 20 ×(0.89) × [1/(1 - 0.89)]

                                      = 343.63 ft.

You will have $3276.44 after 4 years if you deposit $3,000 at an annual interest rate of 2.5%, compounded continuously.

What is continuous compound interest?

In theory, continuously compounded interest means that an account balance is constantly earning interest, as well as refeeding that interest back into the balance so that it, too, earns interest.

The formula for continuously compounded interest is:

              [tex]A = P * e^{rt}[/tex]

where:

A is the ending balance (the amount you will have after 4 years)

P is the principal (the initial amount you deposited, in this case $3,000)

r is the interest rate (2.5% per year, or 0.025)

t is the time in years (4 years)

Plugging these values into the formula, we get:

            [tex]A = $3,000 * e^{(0.025 * 4)}[/tex]

Calculating this gives us an ending balance of $3,276.44.

Hence, you will have $3276.44 after 4 years if you deposit $3,000 at an annual interest rate of 2.5%, compounded continuously.

The measure of the third angle = 105°.

What is angles?

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are on the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.

The sum of the angles in a triangle is :

A° + B° + C° = 180°

Where A, B and C are the three angles in a triangle.

Hence, if two of the angles are given as : 55° and 20°

The measure of the third angle will be :

Let the measure of the third angle = C

(55 + 25 + C) = 180°

180° - (55° + 20°)

180° - 75° = 105°

Answer:

  (B) 146 feet

Step-by-step explanation:

You want to know the maximum height of a pebble whose height is described by p(t) = -16t² + 48t + 110.

We can write the equation in vertex form as follows:

  p(t) = -16(t² -3t) +110

  p(t) = -16(t² -3t +2.25) +110 +16(2.25)

  p(t) = -16(t -1.5)² +146

This shows the vertex of the quadratic curve to be (1.5, 146).

The maximum height of the pebble is 146 feet.

3x + y = 4 and −6x − 2y = −8                   consistent and dependent

A system is considered to be inconsistent if there is no solution. There is no solution because the line graphs are parallel and do not overlap.

x + 5y = −2

x + 5y = 4  

subtracting gives

0 = -6 no solution  

A system is deemed consistent if it has at least one solution.

A consistent system is independent if it only has one solution.

-3x + y = 4

−2x + y = 4  

subtracting gives

-x = 0

x = 0

substituting x to get y

-3 * 0 + y = 4

y = 4

A consistent system is dependent if there are an endless number of possible solutions. The two equations represent the same line when you graph them.

3x + y = 4

−6x − 2y = −8

subtracting gives

9x + 3y = 12 - none cancels out meaning infinite number of possible solutions

Rectangulus, a combination of the Latin words rectus (as an adjective, right, appropriate), and angulus, is where we get the word rectangle (angle).

A crossed rectangle is a crossed (self-intersecting) quadrilateral made up of two opposing sides and the two diagonals of a rectangle[4] (therefore only two sides are parallel). It is a specific case of an antiparallelogram with angles that are not all equal and right angles, even though opposite angles are. Other geometries, including spherical, elliptic, and hyperbolic,  with opposite sides of equal length and equal angles that are not right angles.

Area =Area of the down rectangle+ Area of the up rectangle+2×Area of the triangle

Area= (7×24)+(4×13)+2×(1/2)×b×4

x² - 2px + p² = q

x² - 2px + p² - q = 0

our target is

x² + 4x - 20 = -8

x² + 4x - 12 = 0

now we compare the variable expression with the target.

x² = x² check

4x = -2px

p = -2

-12 = p² - q = 4 - q

-16 = -q

Out of 52, 26 are red and 26 are black.

Each of the four French suits—clubs (♣), diamonds (♦), hearts (♥) and spades (♠).—has 13 ranks in a regular 52-card deck. King, Queen, and Jack are the three court cards (face cards) in each suit, and their pictures are reversed (double-headed). The ten numerical cards, or pip cards, in each suit range in value from one to 10.

Out of 52 cards, (Kings, Queen, Ace) are faced card.

And each set of cards have 4 different colour and shades.

So, total number of faced card will be = 4*3 = 12
