What is the circumference of the circle shown below, given that the length of ED (the minor Arc) is 6?

Answer:

n+11=30

n = 19

Step-by-step explanation:

You have 30 CDs and you friend had n amount of CDs. We also know that you have 11 more CDs than your friends. Therefore we can write expression as:

[tex]n+11=30[/tex] and simplify

[tex]n =30 -11[/tex]

[tex]n=19[/tex]

Therefore you friend will have 11 CDs which is 11 less than what you have.

the number inside the parenthesis includes the interest rate ( annual percentage

looking at the possible functions, if you raise the interest rate to the power of 12, you would need to divide the number of years (t) by 12 as well

 so the function could be rewritten as A=1000(1.023^12)^t/12

 since the annual percentage rate is 2.3% ( 0.023)

 divide 0.023/12*100 = 0.19% per month interest

A triangle with angles that measure 120°, 39°, and 21° is an obtuse triangle.

The student has asked about the classification of a triangle with angles that measure 120°, 39°, and 21°. Based on Euclidean geometry, the sum of the angles in any plane triangle is 180°. A triangle with one angle that measures more than 90° is an obtuse triangle, as it has one obtuse angle. Therefore, this triangle, with a 120° angle, is classified as an obtuse triangle.

Final answer:

By using the given lengths of AE and BC, along with the equality of AB, DB, and DC, we can solve for CE to be 14.67cm.

Explanation:

The lengths of AE, BC, AB, DB, and DC are given or can be determined with the information provided. Since AB = DB = DC and BC is given as 10 cm, we can deduce that AB + BC + CE = AE. Given AE is 28cm and BC is 10cm, we can find the length of AB by realizing that AB + AB + AB (which is AB + DB + DC) is the same as BC or 10cm. This makes each section AB, DB, and DC equal to 10cm / 3.

With AB, DB, and DC all being equal to 10cm / 3, and knowing AE is 28cm, we can then calculate the length of CE:

AE = AB + BE (and BE = BC + CE)

28cm = (10cm/3) + (10cm + CE)

To find CE, rearrange the equation:

CE = 28cm - 10cm - (10cm/3)

CE = 28cm - 10cm - 3.33cm

CE = 18cm - 3.33cm

CE = 14.67cm

To solve for the length of CE in a line segment configuration, we calculate CE = AE - BC - DC after determining the lengths of AB, BC, and DC. The solution reveals that CE is 9cm.

The student has a geometry problem, which involves calculating the length of segment CE on a line segment AE. We know that AE = 28cm and BC = 10cm, with AB, DB, and DC being equal in lengths.

Since B is between A and C, and D is between B and C, and C is between B and E, we can write the entire length AE as AB + BC + CE. Because AB = DB = DC, we can substitute DB and DC for AB in the sums to get 2(DB) + BC = 28cm.

We are given that BC = 10cm, so we can set up an equation: 2(DB) + 10cm = 28cm. Solving for DB, we find that DB = 9cm. Since DC is equal to DB, DC is also 9cm. CE can be found by subtracting BC and DC from the total length of AE: CE = AE - BC - DC, so CE = 28cm - 10cm - 9cm, resulting in CE = 9cm.

A reasonable conjecture for Mei is the Alternate Interior Angles Theorem, which states if a transversal intersects parallel lines, the alternate interior angles are equal.

Based on the scenario, a reasonable conjecture for Mei to make would be, if a transversal intersects parallel lines, then the alternate interior angles are congruent. This statement is known as the Alternate Interior Angles Theorem. In other words, in each of Mei's figures, if the angles she measured are alternate interior angles, they should have the same measurement.

For example, if three pairs of parallel lines are intersected by a third line (called a transversal), a pattern that consistently appears is the equality of the alternate interior angles (angles that are on opposite sides of the transversal and inside the parallel lines). This implies, if the two lines are parallel, then any alternate pair of interior angles are equal.

Answer:

Step-by-step explanation:

Answer:

Real part: -6

Imaginary part: -1

Step-by-step explanation:

A complex number is a number that has a real part and an imaginary part. These numbers usually are represented in the form a + bi where a and b are real numbers and b is the imaginary part (i is actually the solution to the equation [tex]x^{2} +1=0[/tex] or x²=-1 which has no roots in the real numbers and therefore we call the solution √-1=i)

Now, proceeding to the complex number you wrote, if we write it as a + bi we would have a = -6 b = -1

Therefore the real part is a = -6 and the imaginary part would be -1.

Step-by-step explanation:

Area = 338

Width = X

Length = 2x

2x * x = 338

3x = 338

x = 112.7

The value of x from the rectangular shaped canvas box is x = 13 inches

The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle

Area of Rectangle = Length x Width

Given data ,

Let the area of rectangle canvas be A = 338 inches²

Let the width of the canvas = x inches

And , length = 2 x ( width )

Now , the length of the canvas = 2x inches

So , Area of Rectangle = Length x Width

On simplifying , we get

Area of Rectangle = 2x ( x )

Area of Rectangle = 2x²

338 = 2x²

Divide by 2 on both sides , we get

x² = 169

Taking square roots on both sides , we get

x = 13 inches

Hence , the value of x of the canvas is 13 inches
