3 over 7 of 2 over 7 is equal to ​

While guessing and checking is one way to do this problem, I will show you how to do it algebraically.

Let one side be A

Let the other side be B

2(A+B)=16

A*B=15

First equation because the perimeter is 16 and the second because the area is 15. Now solve the system of equations

A+B=8

A=8-B

Substitute into equation two

B(8-B)=15

-B^2+8b-15=0

B^2-8b+15=0

(B+3)(B+5)=0

B=3,5

A=5,3 respectively

From this we can see that one side is 5 meters long while the other side is three meters long.

Step-by-step explanation

Since we're looking at a rectangle, let's consider its perimeter and area formulas.

Perimeter: 2x + 2y (A rectangle has four sides, with two equal sides, so this is x + x + y + y simplified)

Area: (x)(y) (length x breadth so, x times y)

So we have two equations: 2x + 2y = 16 and x*y = 15. Solve simultaneously. Refer to the attached image.

Answer:

5x + 6y

Answer:

To find the volume of a rectangular prism, multiply its 3 dimensions: length x width x height. The volume is expressed in cubic units.

Step-by-step explanation:

..

1)

[tex]m = \frac{y - y}{x - x} = \frac{55 - 59}{10 - 0} = \frac{ - 4}{10} = - \frac{2}{5} [/tex]

[tex]y = - \frac{2}{5} x + b[/tex]

Since the line passes through the point (0,59), the coordinates of this point satisfies the equation of y;

[tex]59 = - \frac{2}{5} (0) + b[/tex]

[tex]b = 59[/tex]

Final answer:

[tex]y = - \frac{2}{5} x + 59[/tex]

Step-by-step explanation:

Equation for the volume of a cone is

V = (pi(r^2)h)/2

Plug in the known values to get

350 = (pi(6^2)h)/2

To find h, just isolate it by first dividing both sides by 2 and squaring 6 to get

175 = pi(36)h

Then, divide both sides by pi36 to get

h = 175/pi(36)

Answer:

The answer is below

Step-by-step explanation:

Given the cost as C(x) = x² + 4x - 40

a) Since the bracelets sell for $8 each, the revenue from x bracelets is given as:

Revenue = price for each bracelet × number of bracelet

Revenue = 8 × x = 8x

b) Profit (P) = Revenue - Cost

P(x) = 8x - [x² + 4x - 40]

P(x) = 8x - x² - 4x + 40

P(x) = -x² + 4x + 40

c) To maximize profit, the derivative of profit is equal to 0

Hence P'(x) = 0

-2x + 4 =0

2x = 4

x = 2

To maximize profit, the company should produce 2 bracelets

d) The maximum profit is:

P(2) = -(2²) + 4(2) + 40 = -4 + 8 + 40

P(2) = $44

The maximum profit is $44

Converse of alternate interior angles theorem:

This theorem states that if two lines are intersected by a transversal and the alternate interior angles are congruent, lines will be parallel.

Therefore, p║n.

Perpendicular transversal theorem:

By this theorem,

In a plane, if a line is perpendicular to one of two parallel lines, then it will be perpendicular to the other line.

Therefore, l ⊥ p.

Area of semicircle:

The length of the longer side of the rectangle will be 8.78 cm.

The area of a two - dimensional figure is the area that its perimeter encloses. The quantity of unit squares that occupy a closed figure's surface is its region.

On one of a rectangle's shorter sides, a semicircle is drawn. The rectangle's shorter side is 4 cm long. The figure has a surface area of 41.4 square centimeters.

Then the length of the rectangle is calculated as,

A = πr² / 2 + l × b

41.4 = (3.14 / 2) × (4/2)² + 4l

41.4 = 6.28 + 4

l = 8.78 cm

The length of the longer side of the rectangle will be 8.78 cm.

Answer:

X= -3 or X=-9

Step-by-step explanation:

Answer: x = -3, x = -9

Step-by-step explanation: |x + 6| + 10 = 13

Firstly, subtract 10 from both sides:

|x + 6| = 3

Since it is an absolute value, separate it into two equations with either outcome:

x + 6 = 3

x + 6 = -3

Solve for x now.

x + 6 = 3

Subtract 6 from both sides:

x = -3

x + 6 = -3

Subtract 6 from both sides:

x = -9

The positive solution of the quadratic equation [tex]\rm 0=-x^2+2x+1[/tex]  is x=2.41

It is given that the quadratic equation:

[tex]\rm 0=-x^2+2x+1[/tex]

It is required to find the solution to the above quadratic equation.

A quadratic equation is a second-degree algebraic equation represented by the:

[tex]\rm ax^2+bx+c=0[/tex]........(1)

Where a, b, and c are the constants and [tex]\rm a\neq 0[/tex]

We know that:

[tex]\rm x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

We have:

[tex]\rm 0=-x^2+2x+1\\\rm or \\\rm -x^2+2x+1=0[/tex] ..........(2)

After comparing (1) and (2) we get:

[tex]\rm a=-1, b=2, and \ c=1[/tex]

Put these values in the above formula we get:

[tex]\rm x=\frac{-2\pm \sqrt{2^2-(4)(-1)(1)}}{(2)(-1)}\\\rm x=\frac{-2\pm \sqrt{8}}{-2}\\\rm x=\frac{-2\pm 2\sqrt{2 }}{-2}\\\rm x={1\pm \sqrt{2}}[/tex]

[tex]\rm x=1+\sqrt{2} \ or \ x=1-\sqrt{2} \\\\\sqrt{2} = 1.41\\\rm so \ x= 1+1.41 \ or \ x= 1-1.41\\\rm x=2.41 or \ x=-0.41[/tex]

Thus, the positive solution of the quadratic equation is x=2.41
