Answer:

60 were left with Ken, and that is 75%

Step-by-step explanation:

80-10 = 70

70-10 = 60

60/80 = x/100, simplify & cross multiply

6/8 = x/100

600 = 8x

x = 75

Given:

The equations of circle are

4. [tex]\left(x+\dfrac{2}{3}\right)^2+(y+1)^2=24[/tex]

5. [tex](x-1)^2+(y+2)^2=28[/tex]

6 .[tex](x+12)^2+y^2=\dfrac{3}{64}[/tex]

To find:

The center and radius for the given circles.

Solution:

The standard form of a circle is:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Where, [tex](h,k)[/tex] is center and [tex]r[/tex] is the radius of the circle.

4.

The equation of the circle is

[tex]\left(x+\dfrac{2}{3}\right)^2+(y+1)^2=24[/tex]

The standard form of this circle is

[tex]\left(x-(-\dfrac{2}{3})\right)^2+(y-(-1))^2=(\sqrt{24})^2[/tex]

[tex]\left(x-(-\dfrac{2}{3})\right)^2+(y-(-1))^2=(2\sqrt{6})^2[/tex]

Therefore, the center of the circle is [tex]\left(-\dfrac{2}{3},-1\right)[/tex] and the radius of the circle is [tex]2\sqrt{6}[/tex].

5.

The equation of the circle is

[tex](x-1)^2+(y+2)^2=28[/tex]

The standard form of this circle is

[tex](x-1)^2+(y-(-2))^2=(\sqrt{28})^2[/tex]

[tex](x-1)^2+(y-(-2))^2=(2\sqrt{7})^2[/tex]

Therefore, the center of the circle is [tex]\left(1,-2\right)[/tex] and the radius of the circle is [tex]2\sqrt{7}[/tex].

6.

The equation of the circle is

[tex](x+12)^2+y^2=\dfrac{3}{64}[/tex]

The standard form of this circle is

[tex](x-(-12))^2+(y-0)^2=(\sqrt{\dfrac{3}{64}})^2[/tex]

[tex](x-(-12))^2+(y-0)^2=\dfrac{\sqrt{3}}{8}[/tex]

Therefore, the center of the circle is [tex]\left(-12,0\right)[/tex] and the radius of the circle is [tex]\dfrac{\sqrt{3}}{8}[/tex].

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

Side links are : 3m, 4m, 5m

The perimeter of a triangle = (a + b + c)

Perimeter 1= (3 + 4 + 5) = 12m

If the side links are multiplied by 4 :

3*4 = 12 m

4*4 = 16m

5*4 = 20m

Perimeter2 = (12 + 16 + 20) = 48 m

Comparing the perimeters:

Perimeter 1 = perimeter 2

12 = 48

Hence, perimeter also increases by 4 folds

Answer:

The answer is below

Step-by-step explanation:

A triangular prism is a polyhedron (three dimensional shape) made up of two equal triangles, two equal rectangle and a base rectangle.

The total surface are of a triangular prism is given as:

A = bh + 2ls + lb

where b is the base of the triangle, h is the height of the triangle, l is the length of the base rectangle and s is the length of the slant side of the triangle.

Given that:

b = 6 ft, s = 5.5 ft, h = 5 ft, l = 9 ft.

Therefore:

A = (6 * 5) + 2(9 * 5.5) + (9 * 6) = 183 ft²

Therefore 183 ft² of fabric is needed to make the tent

The answer is B.............,..,,.....

The solutions of the quadratic equation[tex]-3x^2 + 1 = 3x - 2[/tex] are -1/3 and 1.

To solve this equation, we can use the quadratic formula:

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

In this case, the coefficients are a = -3, b = 3, and c = -2. Substituting these values into the quadratic formula, we get:

[tex]x = \dfrac{(-3 \pm \sqrt{3^2 - 4 \cdot -3 \cdot -2})}{2 \cdot -3}[/tex]

[tex]x = \dfrac{(-3 \pm \sqrt{27 + 24})}{-6}[/tex]

[tex]x &= \dfrac{(-3 \pm \sqrt{51})}{-6} \\x&= \dfrac{(-3 \pm 3\sqrt{7})}{-6}[/tex]

[tex]x = -1/3 or 1[/tex]

Therefore, the solutions of the quadratic equation are -1/3 and 1.

Here is a breakdown of the steps involved in solving for the solutions of the quadratic equation:

We are given the quadratic equation [tex]-3x^2 + 1 = 3x - 2[/tex]

We can identify the coefficients a, b, and c.

We can substitute these values into the quadratic formula.

We can simplify the expression in the quadratic formula.

We can solve for x.

The solutions are -1/3 and 1.

Imagine cutting this shape into two semi-circles and one rectangle.

------------------------------------------------------------------------------------------------------

--------------------------------------------------------------------

We know the area of a whole circle which is π[tex]r^{2}[/tex]

because a semi-circle is basically half of the whole circle!

However, since we have two equal semi-circles...we can just put them together and solve for the whole circle's area.

for reference:

1/2(π[tex]r^{2}[/tex]) + 1/2(π[tex]r^{2}[/tex]) = 2/2(π[tex]r^{2}[/tex]) = π[tex]r^{2}[/tex]

----------------------------------------------------------

First, the area of rectangle: length times width = 84 x 36 = 3024 square meters

Anyways, since we have to sub in 3.14 for π

Area of a whole circle: (3.14 x [tex]r^{2}[/tex]) = (3.14 x [tex]18^{2}[/tex]) = 1017.36 square meters

-----------------------------------------------------------

3024 + 1017.36 = 4041.36 square meters

Step-by-step explanation:

Answer:

24

Step-by-step explanation:

Answer:

Step-by-step explanation:

Circumference of a circle = 2πr

Area of circle = πr²

Here, r = radius of the circle

1). For radius = 1.7 units

Circumference = 2π(1.7)

                         = 2(3.14)(1.7)

                         = 10.676

                         ≈ 10.7 units

Area of the circle = π(1.7)²

                             = 3.14(1.7)²

                             = 9.0746

                             = 9.1 units²

2). For radius = 14 ft

   Circumference of the circle = 2π(14)

                                                 = 28(3.14)

                                                 = 87.92

                                                 ≈ 87.9 ft

    Area of the circle = πr²

                                  = 3.14(14)²

                                  = 615.44

                                  ≈ 615.4 ft²

3). For radius = 9 in.

   Circumference = 2π(9)

                             = 18π

                             = 56.52

                             ≈ 56.5 in

Area of the circle = π(9)²

                             = 81π

                             = 254.34 in²

                             ≈ 254.3 in²

  x = -6 (correct answer)

  mistakes were made in Step 2 and Step 5.

Step-by-step explanation:

The mistake is made in Step 2, application of the distributive property. This is often a source of error. Here, the error is in signs.

Step 1: 12 = -2(x -4) -8

Step 2: 12 = -2x +8 -8 . . . . . . the correct step 2

Step 3: 12 = -2x . . . . . . . . . . . like terms combined

Step 4: -6 = x . . . . . . . . . . . . . divide by -2

__

Check

  12 = -2(-6 -4) -8 = -2(-10) -8 = 20 -8 = 12 . . . . answer checks OK

__

Comment on other mistake

In the original Step 5, -2 was divided on the right and added on the left. This is a violation of the properties of equality, so guarantees a wrong answer. The same operation must be performed on both sides of the equation.

An additional mistake was made in that the answer was not checked.

Step-by-step explanation:

2x^2+6x=36

x^2+3x=12

x^2+3x-12=0

x=(-3+(57)^0.5)/2 or x=(-3-(57)^0.5)/2
