33 degrees

Step-by-step explanation:

Complementary angles are 90 degrees when added.

So to find the measure of the other angle just subtract 57 from 90.

90 - 57 = 33

The 2 digit number is 45 which becomes 5/6th of itself when its digits reversed.

A number is a numerical unit of measurement and labelling in mathematics. The natural numbers 1, 2, 3, 4, and so on are the first examples.

Let the two digits of the number are x and y.

So, the number is 10x + y.

When its digits reversed: the number becomes: (10y + x)

According to the question:

(10y + x) = 5/6 (10x + y)

60y + 6x = 50x + 5y

60y - 5y = 50x - 6x

55x = 44y

x/y = 44/55

x/y = 4/5

Hence, the two digits of the number are 4 and 5 and the number is 45.

The specific range depends on the material properties and the energy levels involved.

The minimum and maximum frequencies for the acoustic and optic modes depend on the specific system or material under consideration. However, I can provide some general information.

Acoustic Mode:

The acoustic mode refers to the propagation of sound waves or vibrations in a material. In a solid, the acoustic mode can have different types, such as longitudinal and transverse modes.

The minimum frequency for the acoustic mode is typically determined by the size and physical properties of the material. In general, it can be close to zero for macroscopic objects or materials with low elasticity.

The maximum frequency for the acoustic mode depends on factors such as the speed of sound in the material and the characteristic dimensions of the system. It can range from a few kilohertz to several gigahertz.

Optic Mode:

The optic mode is related to the interaction of light with a material. It typically refers to the vibrations of charged particles (such as electrons) in a solid or the oscillations of electric or magnetic fields associated with photons.

The minimum frequency for the optic mode is typically determined by the energy gap between electronic states in the material. For example, in a semiconductor, the minimum frequency is usually in the infrared range.

The maximum frequency for the optic mode is not strictly defined, as it can extend into the terahertz, infrared, visible, ultraviolet, X-ray, and even gamma-ray regions. The specific range depends on the material properties and the energy levels involved.

It's important to note that these frequency ranges are general guidelines and can vary depending on the specific system or material being studied.

Answer:

(a) a ≈ 22.7 meters, (b) c ≈ 10.6 meters, (c) ∠A = 65°

Step-by-step explanation:

assuming side a/c is side BC/AB since it's opposite of angle A/C

(a) SOH CAH(cos = adjacent side/hypotenuse) TOA

=> cos (25°) = BC/AC or a/b

=> cos (25°) = a/25

=> a = cos (25°) × 25

=> a ≈ 22.7

(b) SOH(sin = opposite side/hypotenuse) CAH TOA

=> sin (25°) = AB/AC or c/b

=> sin (25°) = c/25

=> c = sin (25°) × 25

=> c ≈ 10.6

(c) 180° - 25° - 90°(the right angle) = 65°

Answer:

The original smaller bottle of shampoo is 5.36 ounce

Step-by-step explanation:

Call the weight of the original smaller bottle = x

If the larger 6.7 ounce give us 25% more free

=> x + 0.25*x = 6.7

=> x * ( 1 + 0.25) = 6.7

=> x = 6.7 / 1.25

=> x = 5.36

The size of the original smaller bottle of shampoo is 5.36 ounces.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

You often purchase the same tiny bottle of shampoo. There is a bigger, 6.7-ounce bottle that claims to provide 25% freer.

Let's represent "x" as the weight of the original smaller bottle

As we know, the larger 6.7 ounces give us 25% freer

This can be represented by an equation, as follows:

⇒ x + 0.25 × x = 6.7

⇒ x × ( 1 + 0.25) = 6.7

⇒ x = 6.7 / 1.25

Apply the division operation, and we get

⇒ x = 5.36

Thus, the size of the original smaller bottle of shampoo is 5.36 ounces.

Slope and a point that is not an intercept is the information about the graph of the relationship is given.

The rate of painting is 8 m²/h.

28 square meters of the room are still left to paint after three hours. Let y represent the area in square meters that needs painting after x hours. We require a corresponding (x,y) pair in order to describe a point on a graph. In our situation, we require data on the rate of change in the correlation between the area still needing painting and the time after business hours. Hiro can paint eight square meters per hour. Thus, the equation Y = 8x, or the associated slope, is 8. (1)

By entering the number Y = 28 square meters into the previous formula 28 = 8X

=> X = 7/2

It is not an intercept but the point (7/2, 28).

∫f(x)dx

The definite integral is a mathematical operation that allows us to calculate the area under a curve by dividing the region into small, narrow rectangles and summing the areas of those rectangles.

Integration is a mathematical operation that allows us to find the area under a curve or the volume of a solid of revolution. It is a fundamental concept in calculus, which is a branch of mathematics that deals with the study of rates of change and the accumulation of quantities.

The definite integral is represented by the symbol ∫, and it is defined as the limit of a sequence of sums as the number of rectangles (n) approaches infinity. The general form of the definite integral is:

∫f(x)dx

where f(x) is the function being integrated and dx is the width of each rectangle. The integral is taken over a range of values, known as the integration limits, which are represented by the lower and upper bounds of the integral (a and b).

For example, if we want to calculate the area under the curve y = f(x) between the points x = a and x = b, we can write the definite integral as:

40 beads

Step-by-step explanation:

First, let's find the length of string that the beads will be on.

The string is originally 20 cm, but 2 cm is taken off each side.

So, the string that the beads will be on is only 16 cm now.

Each bead is 4 mm wide, so we have to convert the bead width to centimeters.

4/10=0.4

So each bead is 0.4 cm.

Now to find how many beads will fit, we have to divide the length by the width of the bead.

16/0.4=40

The inequality 6s - 300 > 210 represents the minimum number of socks (s) when George bought socks for "$"300 and planned to sell them for $6 a pair, and want to make a profit of more than 210.

In the question, we are given that George bought socks for $300.

Therefore, George's total cost = $300.

We assume the number of pairs of socks George sells to be s.

The unit price per pair quoted by George = $6

Therefore, George's total sales = $6s.

We know that the profit over a transaction is given as the difference between sales and costs, that is,

The profit = The total sales - the total costs,

or, profit = 6s - 300.

In the question, we are required to make a profit of more than 210.

This can be shown by the inequality,

6s - 300 > 210.

Thus, the inequality 6s - 300 > 210 represents the minimum number of socks (s) when George bought socks for "$"300 and planned to sell them for $6 a pair, and want to make a profit of more than 210.

(4x³ + 11x² + 0x + 9) + (x+3) [here, we will include 0x to do long division]

Divide 4x³ by x to get first term of the quotient, 4x³

Then, take 4x² and multiply it with 3 and you will get 4x² + 12

Subtract 4x² + 12 from 4x³ + 11x².

Then, you will get the remainder as -x² + 0x

Now you have to repeat the same same process, divide -x² by x to get second term of quotient, -x

Then take -x and multiply with 3 and you will get -x²- 3x

You will get the remainder as 3x+ 9

Divide 3x by x to get the third term of quotient, 3

Then, take 3 and multiply with 3 and you will get 3x + 9

Interference is a property of ALL the given wave options, which are light waves, sound waves, and water waves.

Interference is the phenomenon of two or more waves combining to form a resultant wave of greater, lower, or the same amplitude.

When two waves meet at the same point at the same time, they either combine constructively (resulting in the formation of a wave of greater amplitude) or destructively (resulting in the formation of a wave of lower amplitude).

For instance, when two sound waves or light waves meet, they create a resultant wave whose amplitude is equal to the sum of the two original waves.

This is known as constructive interference.

On the other hand, when two waves meet and their amplitudes are in opposite directions, they produce a resultant wave whose amplitude is equal to the difference between the two waves.

This is known as destructive interference.
