Answer:

576 sq cm

Step-by-step explanation:

For example imagine a rectangle, the area of which is width * height = area

If you multiply the dimensions by 2 you multiply the width AND the height which is 2 * width * 2 * height = 4 * width * height

This is true for all scalings, if you times the dimensions by n, you times the area by n^2

144 * 2^2 = 576

Therefore , the solution of the given problem of unitary method comes out to be Jill exercised every morning for 30 days as a result.

By applying what was acquired and bringing this variable tactic into practise, along with all supporting information from two people who used a particular tactic, the work can be finished. In other words, if the wanted expression result occurs, either the entity specified in the formula will also be discovered, or both crucial processes will actually ignore the colour. A refundable fee of Rupees ($1.01) may be necessary for forty pencils.

Here,

Let's designate the quantity of morning workout days Jill completed "x".

Jill exercised for a total of 2550 minutes, so her morning and afternoon workouts together accounted for the following amount of minutes:

25x + 1800

Additionally, we are aware that this sum equals 2550:

25x + 1800 = 2550

We can first identify the variable component on one side of the equation by deducting 1800 from both sides in order to find x:

25x = 2550 - 1800

25x = 750

Then, by multiplying both sides by 25, we can find the value of x:

=> x = 750/25

x = 30

Jill exercised every morning for 30 days as a result.

Answer:

33 , 39

Step-by-step explanation:

given

9 , 15 , 21 , 27

there is a common difference between consecutive terms, that is

15 - 9 = 21 - 15 = 27 - 21 = 6

to obtain terms in the sequence add 6 to the preceding term

27 + 6 = 33

33 + 6 = 39

Answer:

39.30 \(cm^{2}\)

Step-by-step explanation:

The area of the top surface of the wedge is the same as the area of a sector.

Area of a sector = (θ/\(360^{o}\))\(\pi\)\(r^{2}\)

where: θ is the central angle, and r is the radius.

Given that: central angle = \(45^{o}\), radius = 10 centimetre.

Area of the top surface = Area of a sector = (θ/\(360^{o}\))\(\pi\)\(r^{2}\)

                                      = \(\frac{45^{o} }{360^{o} }\) x \(\frac{22}{7}\) x \((10)^{2}\)

                                      = \(\frac{1}{8}\) x \(\frac{22}{7}\) x 100

                                      = 39.2857

                                     = 39.30 \(cm^{2}\)

The area of the top surface of the wedge is 39.30 \(cm^{2}\).

The area of the top surface of wedge shaped cheeses bought by Mai is 39.3 cm².

The area of a circular sector is the total space occupied by it. The sector area is half of the product of the square of radius of the circle and the central angle.

It can be calculated if theta is measure in radian as,

\(A_{sector}=\dfrac{r^2\theta}{2}\)

It can be calculated if theta is measure in degrees as,

\(A_{sector}=\dfrac{\pi r^2\theta}{360}\)

Here, (r) is the radius of the circle and (θ) is the central angle.

Several different cheeses are for sale. The cheese comes in wedges shaped like sectors of a circle. All of the wedges are the same height.

Mai bought a wedge with a central angle of 45 degrees and radius 10 centimeters. Thus, the area of the top surface of this wedge is,

\(A_{sector}=\dfrac{\pi (10)^2(45)}{360}\\A_{sector}\approx 39.3\rm\; cm^2\)

Thus, the area of the top surface of wedge shaped cheeses bought by Mai is 39.3 cm².

An important concept of unit circle in geometry and trigonometry is it helps us to understand and visualize the values of sine, cosine, and tangent functions for different angles.

The unit circle is a circle with a radius of 1 unit, centered at the origin of a coordinate plane.

The coordinates of points on the unit circle correspond to the values of sine and cosine of the corresponding angle.

For example, if we draw a line from the origin to a point on the unit circle that makes an angle of θ with the positive x-axis.

The x-coordinate of that point is cos(θ) and the y-coordinate is sin(θ).

The unit circle is also useful for understanding and visualizing the properties of periodic functions, such as sine and cosine.

Since sine and cosine are periodic with a period of 2π, the unit circle repeats itself every 2π radians or 360 degrees.

Which makes it easier to analyze and graph these functions.

In addition, the unit circle helps us understand the relationships between trigonometric functions.

Pythagorean identity (sin²(θ) + cos²(θ) = 1) is a fundamental relationship that is easy to see and prove using the unit circle.

Overall, the unit circle is an important concept that provides a visual and geometric representation of trigonometric functions and their properties.

It can be a useful tool for solving problems in geometry and trigonometry.

As well as for understanding more advanced concepts in calculus and other branches of mathematics.

Commission = 15%

using the above as a guide, we have the following:

Total earnings = 400 + 15% * Total sales

So, we have

Total earnings = 400 + 15% * 7000

Therefore the result of adding the system of equations  2x + y = 4  ,

6=3x-y is 5x =10

Equations are statements in mathematics containing the equals (=) sign flanked on either side by two algebraic expressions. The relationship between the expressions printed on the left and right sides is shown to be equal in this way. In all mathematical equations, LHS = RHS  is used. You can solve equations to find the value of an unknown variable that stands in for an unknown quantity. If a sentence lacks a "equal to" sign, it is not considered an equation. It will be considered to be a phrase.

S = 23.6

Step-by-step explanation:

Since this is a right triangle, we can use  trig functions

sin S = opp / hyp

sin S = 4/10

sin S = 2/5

sin^-1 ( sin S) = sin ^-1 (2/5)

S=23.57817

Step-by-step explanation:

Simply divide 200 by 15, then round up because the answer should be a full week:

200 / 15 = 13.3333 ≈ 14 weeks

For an equation, let x be weeks passed and y be money left. Since the money is spent at a constant rate, the equation will have a constant slope, and the y intercept is 200, since at no money spent, Micah has $200:

y = -15x + 200

For a ratio table, it might look something like this:

The value of x in chords is 25.857 and this is a isosceles triangle.

In geometry, a chord is a line segment that connects two points on the circumference of a circle. A chord is the longest distance between two points on a circle, and it passes through the center of the circle. The endpoints of a chord are referred to as its "endpoints." A chord that passes through the center of a circle is called the "diameter" of the circle. The length of a chord can be calculated using the Pythagorean theorem, given the radius and the distance between the center and the chord. Chords are used in various geometric calculations involving circles, such as finding the area of a sector or segment of a circle.

The sum of the angles of a triangle is 180 degrees. In a circle, the angle subtended by an arc at the center of the circle is twice the angle subtended by the same arc at any point on the circumference. Using these facts, we can set up the following equation to find x:

(1/2)(14x - 7) + (1/2)(12x + 4) + (1/2)(4x) = 180

Simplifying and solving for x, we get:

7x - 1 = 180

7x = 181

x = 25.857

Therefore, x is approximately equal to 25.857.

Then it will take approximately 6.3 hours for the culture to grow to 80,000 bacteria

The given formula for the number of bacteria in a culture after t hours is:y = 5000(3)^tWe are required to find the number of hours it will take the culture to grow to 80,000.

This can be done by setting y equal to 80,000 and then solving for t.5000(3)^t = 80,000

Divide both sides by 5000:3^t = 16Now, we need to solve for t by taking the logarithm of both sides.

However, it is easier to use logarithmic properties to simplify the equation first.3^t = 2^4

Raise both sides to the power of (1/log3):log3(3^t) = log3(2^4)t = 4/log3(2)Using a calculator, log3(2) ≈ 0.631, so:t ≈ 4/0.631 ≈ 6.3.
