The sum of 3 consecutive odd numbers is 69

There is 1 solution, which is 3/4.

To show this, you actually have to solve the equation. First, you distribute -1 into(9 - 3h) and distribute -3 into (h + 2). In doing so, you should be left with "6h - 9 + 3h = 6 - 3h - 6". Next you combine like terms on each side, so you add 3h to 6h and you subtract 6 from 6. Now you should have "9h - 9 = -3h". Then, you start to solve by subtracting 9h from both sides. You should have -9 = -12h, which you divide -12 on both sides to get h by itself. Finally, you have h = 9/12 (since the negatives on the top and bottom cancel out) which simplified (divided by 3/3) is 3/4. Thus meaning there is only 1 answer.

We know that the perimeter is 72 meters, so we have

[tex] y+2x+(2x+6)=72 \iff y+4x+6=72 \iff y=-4x+66 [/tex]

Now we can use the pythagorean theorem: the sum of the squares of the legs is the square of the hypotenuse:

[tex] (2x)^2+(2x+6)^2 = y^2 \iff (2x)^2+(2x+6)^2 = (-4x+66)^2 [/tex]

Expand the squares to get

[tex] 8 x^2 + 24 x + 36 = 16 x^2 - 528 x + 4356 [/tex]

Bring everything to the right hand side to get

[tex] 8 x^2 - 552 x + 4320 = 0 [/tex]

Divide both sides by 8:

[tex] x^2 - 69x + 540 = 0 [/tex]

This equation has solutions [tex] x=9,\ x=60 [/tex]

This solutions would yield the following side lengths:

[tex] x=9\implies\begin{cases} 2x = 18\\2x+6=24\\-4x+66=30\end{cases}[/tex]

[tex] x=60\implies\begin{cases} 2x = 120\\2x+6=126\\-4x+66=-174\end{cases}[/tex]

Since we can't have negative side lengths, we can only accept the solution x=9.

In fact, you can check that 18,24,30 is a pythagorean triplet, i.e.

[tex] 18^2+24^2=30^2 [/tex]

By dividing the total amount of $96.15 by the cost of one T-shirt at $13.75, you can estimate buying approximately 7 T-shirts. You round down to the nearest whole number, so you can purchase 7 T-shirts.

To estimate the number of T-shirts you can buy with $96.15, when each T-shirt costs $13.75, you first divide the total amount of money earned by the cost of one T-shirt.

$96.15 ÷ $13.75 = approximately 7 T-shirts

Since you can't buy a fraction of a T-shirt, you will round down to the nearest whole number. Therefore, you can purchase 7 T-shirts with $96.15, assuming there is no sales tax or additional costs.

The side lengths of a square in which the perimeter of a square is greater than its area is 1 unit, 2 units, and 3 units.

A square is a 2D figure of which all sides are equal.

We know that the perimeter of a square is the sum of the lengths of all the sides and the area of a square is (side)².

Assuming a square has a side length of 4 units.

Therefore the perimeter of the square is 4×side = 4×4 = 16 units.

Now the area of the square will be (4)² = 16 sq units.

Now assuming the side length of the square is 2 units.

The area of the square is (2)² = 4 units and the perimeter is (2×4) = 8 units.

∴ The side length which provides a counter-example is 2 units.

Basically, we have to determine the numbers that when multiplied by 4 are greater than it's square such numbers are 1, 2, 3.

Given equation: 3 + x/2 = 10

1st step subtract 3 from each side:

x/2 = 7

2nd step multiply both sides by 2:

x = 14

Step 1)        

3 + x/2 = 10 ..............This is given

Step 2)

x/2 = 7 ....................... Multiplication property of equality.

This step is wrong. This step is called "Subtraction property of equality". This means you have to subtract 3 from both sides

3 + x/2 - 3 = 10 - 3

Simplifying

x/ 2 = 7

Step 3)

x = 14 ....This is called "Multiplication property of equality" because you multiply both sides by 2.

If we draw the diagonals of the octagonal gazebo, the 4 diagonals divide the octagon into 8 triangles.

Note that each triangle is an isosceles triangle whose equal sides are x, the radius of the circle.

The top angle of each triangle is obtained by dividing the full angle by 8.

So, each top angle = [tex]\frac{360}{8}[/tex]

= 45°

Now, in fig., consider one of the triangles Δ OAB. Draw an altitude OC from O to the opposite side AB.

This altitude OC bisects the top angle 45°.

Therefore, ∠ AOC = 22.5°.

Now, in Δ AOC,

[tex]sin 22.5=\frac{AC}{OA}[/tex]

[tex]=\frac{AC}{x}[/tex]

So, AC = x sin 22.5°

Note that, AB = 2 AC.

Therefore, AB = 2x sin 22.5°.

Also, [tex]cos 22.5=\frac{OC}{OA}[/tex]

[tex]=\frac{OC}{x}[/tex]

So, OC = x cos 22.5°.

Area of Δ AOB = [tex]\frac{1}{2}(AB)(OC)[/tex]

= [tex]\frac{1}{2}[/tex] × (2x sin 22.5°) × (x cos 22.5°)

= [tex]\frac{1}{2} x^{2}[/tex] (2 sin 22.5° cos 22.5°)

= [tex]\frac{1}{2} x^{2}[/tex] sin 45°

= [tex]x^{2}[/tex] / [tex]2\sqrt{2}[/tex]

Area of the octagonal gazebo = 8 × one triangular area

= 8 × ([tex]x^{2}[/tex] / [tex]2\sqrt{2}[/tex])

[tex]=2\sqrt{2} x^{2}[/tex]

[tex]=2.828x^{2}[/tex]

Area required for mulch = circular area - area of the gazebo

[tex]=3.14x^{2} -2.828x^{2}[/tex]

[tex]=0.312x^{2}[/tex]

Now, cost per unit area = $1.50.

Hence, total cost g(m) = area × cost per unit area

Total cost g(m) = [tex]0.312x^{2}[/tex] × 1.5

[tex]=0.468x^{2}[/tex]

Hence, total cost g(m) = [tex]0.468x^{2}[/tex].

The slope of a line from the given graph is -2/3. Therefore, option B is the correct answer.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

From the given graph,

Slope (m) = Rise/Run

= -1/1.5

Multiply both numerator and denominator by 2, we get

Hey there!!

In order to solve for the area, let's divide this figure into two rectangles.

Area of a rectangle = Length × Breadth

First rectangle at the top - Length = 8 and width = 3

Hence, the area would be = 24cm²

The second triangle measures : Length = 3 and the width = 5

Area = 3 × 5

... 15cm²

Total area = 24cm² + 15cm²

... 24 + 15 cm²

... 39cm²

Answer:

Option D is the answer.

Step-by-step explanation:

The circle given on the graph has the center at origin (0, 0).

We have to find the point (2, √6) lies on the circle or not.

If the point lie on the circle then distance of this point from origin = radius of the circle.

Given from the graph radius = 3 units

Now distance of point (2, √6) from (0, 0) = [tex]\sqrt{(2-0)^{2}+(\sqrt{6}-0)^{2}} =\sqrt{4 + 6}=\sqrt{10}=3.16[/tex]

Distance between the point and origin is more than radius 3 units.

Therefore point doesn't lie on the circle.

Option D is the answer.

Answer:

(1+2i)(1-2i)

Step-by-step explanation:

Answer:

(1+2i)(1-2i)

Step-by-step explanation:

Following are the pairs of the complex number:

(1+2i)(8i),

(1 + 2i)(2 – 5i)

(1+2i)(1-2i) and (1+2i)(4i)

We have to check which pair out of these is a real number product, which means which pair do not contain terms consisting of "i".

A. [tex](1+2i)(8i)= 8i+16i^{2}[/tex]

                        =[tex]8i-16[/tex]

B. [tex](1+2i)(2-5i)=2-i-10i^{2}[/tex]

                           =[tex]12-i[/tex]

C. [tex](1+2i)(1-2i)=1^{2}-4i^{2}[/tex]

D. [tex](1+2i)(4i)=4i+8i^{2}[/tex]

                        =[tex]4i-8[/tex]

Since, A,B,D contains the term "i" which means they are not real valued, therefore option C that is (1+2i)(1-2i) has a real number product.
