Answer:

21/6 can be divided by 3, so 7/2

7/2 cannot be divided into any more shared factors, so final answer is 7:2.

Answer:

The Answer is B. 2-5n

Step-by-step explanation:

Multiply 2 by everything within the parenthesis and it leaves you with 3n+ 2-8n

Then combine like terms which are +3n and -8n which leaves you with -5n

Answer (it stays the same):

Answer:

Step-by-step explanation:

Part A: 5/26

Part B: 5/26+ 1/2 which is 18/26 or 9/13

Part C: 5/26 +21/25. 'without replacing' means there is one less option in the bag. So denominator becomes 26-1=25. Numerator is 21 because there are a total of 21 consonants in the alphabet. Since we removed a vowel and not a consonant, it will remain 21.

The square root of 12 is approximately 3.4641.

The square root of 12 is an irrational number, meaning it cannot be expressed as a fraction or terminating decimal. However, we can approximate its value.

To approximate the square root of 12, we can use a calculator or perform an estimation. The square root of 12 is approximately 3.4641.

When we multiply 3.4641 by itself (3.4641 * 3.4641), we get a value very close to 12, but not exactly 12 due to the irrational nature of the square root.

The square root of 12 represents a number that, when multiplied by itself, equals 12. It is a non-repeating, non-terminating decimal that goes on infinitely. The approximation 3.4641 is commonly used to represent the square root of 12 in practical calculations.

What is the square root of 12?

Answer:

2.62500

Step-by-step explanation:

just use a calculator

The value of the expression mn/6 + 10 at m = 7 and n = 6 is 17.

An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.

The variable part of an algebraic expression can never be added or subtracted from the constant part.

The given expression is as follows,

mn/6 + 10

Its value can be found at m = 7 and n = 6 as follows,

mn/6 + 10

= (7 × 6)/6 + 10

= 7 + 10

= 17

Hence, the value of the given expression at  m = 7 and n = 6 is 17.

Answer: rotation can be expressed as the composition of two reflections. A composition of reflections over two parallel lines is equivalent to a translation. Example: Given a || b, and pre-image ΔABC, where parallel lines are vertical. The composition of reflections over two intersecting lines is equivalent to a rotation. A composition of transformations is a combination of two or more transformations, each performed on the previous image. A composition of reflections over parallel lines has the same effect as a translation (twice the distance between the parallel lines). i hope this helps.

The expression that is equivalent to 2cos²(x/2) - cos(x) is 1.

These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operations.

Here,
We can use the double angle identity for cosine, which states that:

cos(2θ) = 2cos²(θ) - 1

To simplify given expression expression by putting cos(x) = 2cos²(x/2) - 1 as follows:

= 2cos²(x/2) - cos(x)

= 2cos²(x/2) - 2cos²(x/2) + 1  (using the identity cos(2θ) = 2cos²(θ) - 1)

= 1

Therefore, the expression that is equivalent to 2cos²(x/2) - cos(x) is 1.

Answer:

The measures of the other interior angles are 15° and 105°

Step-by-step explanation:

The given parameter of the measures of the interior angles of the triangle are;

The measure of one of the interior angle of the triangle = 60°

The ratio of the measure of the other interior angles = 1 : 7

Let the x represent one of the other interior angles and y represent the third interior angle, we have;

x + y = 180 - 60 = 120

x : y = 1 : 7

x = 1 part of 8 parts of 120°

y = 7 parts of 8 parts of 120°

Therefore;

x = 1/(1 + 7) × 120 = 1/8 × 120° = 15°

x = 15°

y = 7/(1 + 7) = 7/8 × 120° = 105°

y = 105°

The measures of the other interior angles are 15° and 105°.

03:24 PM

Step-by-step explanation:

Given

[tex]Start\ Time = 3:00PM[/tex]

WMTH = Every 12 minutes

WMSU = Every 8 minutes

Required

Determine when they both play the song

To do this, we simply solve for the LCM of 8 and 12

List the factors of 8 and 12

[tex]8 : 8, 16, 24...[/tex]

[tex]12: 12, 24, 36...[/tex]

From the above, the least common multiple is 24

This means that the song will be played on both stations 24 minutes after 3:00PM

In other words, 03:24 PM

Answer:

Did you learn about equal rectangles? we can prove AEB and CED are equal, which results in what we need to prove here

AE = CE and BE = DE. This can be proved with the help of the properties of congruent triangles.

'A parallelogram is a special kind of quadrilateral that is formed by parallel lines. The angle between the adjacent sides of a parallelogram may vary but the opposite sides need to be parallel for it to be a parallelogram. A quadrilateral will be a parallelogram if its opposite sides are parallel and congruent.'

According to the given problem,

ABCD is a parallelogram.

We know,

BC ║ AD and BC ≅ AD

From, the properties of a parallelogram,

∠CBD = ∠ADB

∠BCA = ∠DAC

We know, two lines are parallel and alternate interior angles of the parallelogram are equal.

Also, Δ BEC ≅ ΔAED (Angle-Side-Angle)

Therefore, AE ≅ CE ( The properties of congruent triangles )

                  BE ≅ DE ( The properties of congruent triangles )

Hence, we can conclude, in the parallelogram ABCD, AE = CE and BE = DE from the properties of congruent triangles.
