The one that is a step used in the construction of an equilateral triangle inscribed in a circle  is:

B. draw two line segments connecting the points where the arc intersects the circle and an endpoint of the diameter

The steps to construct an equilateral triangle inscribed in a circle are:

1. Draw a point that will be the center of the circle. Label this "point O". Technically, it doesn't matter which character you use to represent a point.

2. Draw a perfect circle centered at point O using a compass.

3. Use a ruler to draw a straight vertical line through point O. Extend this line beyond the boundaries of the circle. 4) Draw a point where the line and the circle intersect. Label the bottom point "Point W" and the top point "Point X".

5) Draw a second circle. The center of this circle is point W and the radius extends to point O.

6) Mark both places where the two circles intersect. Label the left point "Point Y" and the right point "Point Z".

7) Connect the points X, Y and Z with a ruler or straightedge. 

Looking at the options, the only correct step is:

B. draw two line segments connecting the points where the arc intersects the circle and an endpoint of the diameter

Step-by-step explanation:

Answer: 448 divided by 7 = 64

Step-by-step explanation:

To find how many miles per hour (how far he traveled each hour) divide the number of miles he went (448) by how long it took him to get that far (7 hours)

448 divided by 7 = 64

Adam was going at a constant rate of 64 mph.

Hope this helps!

The distance traveled in one hour is 64 miles.

Given,

Adam drove 448 miles in 7 hours.

He drove at a constant rate.

We need to find how far did he travel each hour.

Division is a process of splitting a specific amount into equal parts.

We have,

448 miles= 7 hours

Find the number of miles per hour.

448 = 7 hours

Dividing both sides by 7.

448/7 miles = 7/7 hours

[ 7 X 64 = 448 ]

64 miles = 1 hour

This means in one hour 64 miles are driven if traveled at a constant rate.

Thus the distance traveled in one hour is 64 miles.

Answer:

11.2square feet

Step-by-step explanation:

Area of a sector = theta/360 * πr²

theta is the central angle = 80degrees

radius r = PC = 4ft

Substitute

Area of the sector = 80/360 * 3.14 * 4²

Area of the sector = 80/360 * 3.14 * 16

Area of the sector = 4,019.2/360

Area of the sector = 11.2ft²

Hence tthe area of the blue sector is 11.2square feet

Answer: (-3.5 + (-1.5))

Step-by-step explanation:

Given the expression :

The temperature in the morning was -3.5 °F. By noon, the temperature had dropped by 1.5 °F. Write an addition expression to represent this scenario.

Morning temperature : - 3.5°F

By Noon : change (drop) in temperature

Addition expression to represent the scenario :

A drop in temperature means a further reduction in the initial temperature level :

Addition expression :

(Morning temperature + ( - drop in temperature))

(-3.5 + (-1.5))

Step-by-step explanation:

Let's solve this using the information we have and an equation.

Shane: $32,000 - (Given)

Theresa: 18,000+14x, if x=1,160 - (Given)

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

Step two: (Theresa) 14(1,160) =16,240 (Algebra)

Step three: (Theresa) 18,000+16,240=34,240 (Algebra, given.) - cost of Theresa's car.

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

Finally,

They're asking for how much more she paid for her car as a percentage of what Shane paid.

34,240-32,000=2,240 and

2,240/32,000=0.07

0.07x100=7

Answer 7% more than what Shane paid.

La tableta de chocolate de Demetrio puede representarse como la unidad entera. Si Demetrio dejó 1/4 de la tableta para sí mismo, entonces se puede decir que se comió 3/4 de la tableta.

A continuación, si le dio 1/3 de la tableta a su hermano, entonces queda:

3/4 x 1/3 = 1/4

Por lo tanto, Demetrio le dio 1/4 de la tableta a su hermano.

Teniendo en cuenta que le quedaba 1/4 de la tableta, se puede deducir que eso es lo que le dio a su profesor.

En resumen, Demetrio se comió 3/4 de la tableta, le dio 1/4 de la tableta a su hermano y el otro 1/4 de la tableta se lo dio a su profesor.

Rounding to the nearest thousandth, the margin of error for this survey, expressed as a proportion, is approximately 0.020.

To calculate the margin of error for a survey, we can use the formula:

Margin of Error = Z × √((p × (1-p)) / n)

Where:

Z represents the z-score corresponding to the desired confidence level,

p represents the proportion of respondents who preferred candidate A,

n represents the sample size.

The sample size (n) is 1900, and the proportion of respondents who preferred candidate A is 1520/1900.

p = 1520/1900

≈ 0.8

We need to find the z-score corresponding to a 95% confidence level. For a 95% confidence level, the z-score is approximately 1.96.

Substituting the values into the formula:

Margin of Error = 1.96 × √((0.8 × (1-0.8)) / 1900)

Calculating the expression inside the square root:

(0.8 × (1-0.8)) ≈ 0.16

Margin of Error = 1.96 × √(0.16 / 1900)

Calculating the square root:

√(0.16 / 1900) ≈ 0.01016

Margin of Error = 1.96 × 0.01016

≈ 0.0199

For the polynomial with  degree 5. P(x) that has a leading coeficient of -4, has roots of multiplicity 2 at x = 3 and x = 0 and a root at x = - 4

1. The factored polymomial is -4x²(x + 4)(x - 3)²

2. The expanded form of the polynomial is -4x⁵ + 8x⁴ + 60x³ - 144x²

A polynomial is an algebraic equation in which the least power of the unknown is 2.

Given the polynomial of degree 5. P(x) that has a leading coeficient of -4, has roots of multiplicity 2 at x = 3 and x = 0 and a root at x = - 4. To write a polynomial in factored form and expanded form, we proceed as follows

1. To write the polynomial in factored form, we notice that the roots of the polynomial are

So, the factors are

So, the polynomial P(x) with leading coefficient - 4 in factored form, we multiply the factors together as well as the leading coefficient. So,

P(x) = -4(x - 3)²x²(x + 4)

= -4x²(x + 4)(x - 3)²

So, the polynomial is -4x²(x + 4)(x - 3)²

2. To find the polynomial in expanded form, we proceed as follows.

Since P(x) = -4x²(x + 4)(x - 3)², we expand the brackets. So, we have that

P(x) = -4x²(x + 4)(x - 3)²

= -4x²(x + 4)(x² - 6x + 9)

= -4x²(x³ - 6x² + 9x + 4x² - 24x + 36)

Collecting like terms, we have that

= -4x²(x³ - 6x² + 4x² + 9x - 24x + 36)

= -4x²(x³ - 2x² - 15x + 36)

= -4x⁵ + 8x⁴ + 60x³ - 144x²

So, the expanded form is -4x⁵ + 8x⁴ + 60x³ - 144x²

At a local high school, enrollment in the drama club increases by 5%. the common ratio will be 1.05.

A percentage is a minimum number or ratio that is measured by a fraction of 100.

At a local high school, enrollment in the drama club increases by 5%.

Let an initial number of students in high school be 'a'.

so next year increase in students will be = 5% of a

                                                                   = 5/100 × a

                                                                   = 0.05a

and total number of the students will be  = ( a + 0.05a )

                                                                   = ( 1.05a )

△LAJ ≅△KAJ by SAS rule. So, FA bisect Angle LJK.

If two shapes are similar in size and shape, they are congruent. We can also state that if two shapes are congruent, then their mirror images are identical. If and only if two angles have equal measurements, they are said to be congruent.

Given that FA bisects ∠F and ∠A

Prove: FA bisects ∠LJK

Thus,

△ALF ≅△AKF    (ASA rule)
