b.(1, 1)
c.(2,-3)
d.(2,4)​

Answer: False.

Step-by-step explanation: The two equations are not equivalent because the constant terms on the right side of each equation are different. The first equation has -20 on the right side, while the second equation has 0 on the right side. The equations cannot be manipulated into each other because the constant terms are different.

40 minutes past 7:00 is the actual time when the chicken will get ready.

The tool used to measure and indicate time is a clock or timepiece. The clock, one of the earliest creations by humans, satisfies the need to measure time periods that are shorter than those represented by natural units like the day, lunar month, and year. Over thousands of years, several physical processes have been utilized by devices.

The following examples of clocks that are based on movement in nature could be regarded forerunners of the modern timepiece: Through the positioning of a shadow on a flat surface, a sundial displays the time.

The hourglass is a well-known illustration of the variety of duration timers available. The two possible oldest clocks used to measure time are sundials and water clocks.

In Europe, the earliest mechanical clocks that kept time with oscillating timekeepers such balance wheels were made possible around 1300 thanks to the development of the verge escapement, which was a significant advancement.

Given the current time is 10 minute past 7:00, i.e. 7:10

But the clock is 15 min faster the original time

Original time = 7:10 - 15 min

= 6:55

And given time for the chicken to get ready is 45 min

Adding 45 min

= 6:55 + 45 min

= 7:40

Thus, 40 minutes past 7:00 is the actual time when the chicken will get ready.

The starting temperature would be 29 degrees.

What are the initial value and final value?

Initial value refers to the starting value or the value of a variable at the beginning of a process or time period. Final value refers to the end value or the value of a variable at the end of a process or time period. In the context of a mathematical function, the initial value would be the value of the function at the beginning of the domain and the final value would be the value of the function at the end of the domain.

If the temperature outside dropped 23 degrees in 6 hours. The final temperature was -6,

The starting temperature would be 29 degrees (-6 + 23).

Hence, the starting temperature would be 29 degrees.

The greatest number of stickers Susi can make with 2 sheets of sticker paper is 128.

What is a fraction?

A fraction is a way of representing a part of a whole or a ratio of two numbers. It is written as a ratio of two numbers, called the numerator and the denominator, separated by a horizontal line or a slash.

Each sheet of sticker paper can be used to make 1/16 of a sheet of stickers, so two sheets of sticker paper can be used to make 2 * (1/16) = 2/16 = 1/8 of a sheet of stickers.

Since a sticker uses 1/16 of a sheet, the greatest number of stickers Susi can make from 2 sheets of sticker paper is 1/8 * (1/1/16) = 8 * 16 = 128 stickers.

Hence, the greatest number of stickers Susi can make with 2 sheets of sticker paper is 128.

The ratios 40/18 and 27/11 are not equal because 20/9 and 3/1 are different fractions. They stand for various proportional connections between two quantities, in other words.

We need to see if the ratios of 40/18 and 27/11 fall to the same fraction when the numerator and denominator are both divided by their largest common factor (GCF).

Given that the GCF of 40 and 18 is 2, we can obtain 20/9 by reducing both the numerator and denominator of 40/18 by 2. Since the GCF of 27 and 11 is also 11, we obtain 3/1 when we divide the numerator and denominator of 27/11 by 11.

The value of x is 28.4°. The solution has been obtained using the law of cosines.

What is law of cosines?

The law of cosines, commonly referred to as the cosine rule or the cosine formula, in trigonometry essentially connects the length of the triangle to the cosines of one of its angles.

Law of Cosines: c² = a² + b² - 2ab cos C

We are given a= 37, b=23 and x= 20

Using the law of cosines,

⇒x² = a² + b² - 2ab cos x

⇒20² = 37² + 23² - 2(37)(23) cos x

⇒20² = 37² + 23² - 2(37)(23) cos x

⇒400 = 1369 + 529 - 1702 cos x

⇒400 = 1898 - 1702 cos x

⇒1702 cos x = 1498

⇒cos x = 1498 /1702

⇒cos x = 0.88

⇒x = [tex]cos^{-1} (0.88)[/tex]

The distance between the point (-5, 6) to the origin is 61 units.

Regardless of direction, an object's distance is defined by its total velocity.

Distance is the amount of space an object has traveled, regardless of where it began or concluded.

Knowing an object's distance from us allows us to determine its true size.

The following formula is widely used to determine the distance between two points: d=((x2 - x1)2 + (y2 - y1)2)

The given point is thus:

(-5, 6)

Assume that (0, 0) serves as the origin and that the given position is at (-5, 6).

d=((-5 - x1)2 + (6 - y1)2)

d=((-5)2 + (6)2)

d=25+36

Answer:

Step-by-step explanation:

A quadrilateral is cyclic if and only if the opposite angles are supplementary, or add up to 180 degrees. Angle ABC is equal to angle BCD in the diagram because they are opposing angles of a parallelogram.

Furthermore, because AB=BC, the opposite angles are congruent, which implies they are equal. Because angle ABC equals angle BCD, angle ABC Plus angle BCD equals 180 degrees. As a result, we may deduce that ABCD is a cyclic quadrilateral.

Another technique to demonstrate that ABCD is a cyclic quadrilateral is to use the theorem "In a parallelogram, opposite sides and opposite angles are equal."

A parallelogram has equal opposed sides and equal opposite angles. We know that AB=BC in this situation, thus AB and BC are opposing sides, implying that the quadrilateral is a parallelogram. And because the opposite angles are equal, the quadrilateral is cyclic.

As a result, the congruence of parallel sides and opposing angles establishes that the quadrilateral is a cyclic quadrilateral.

A line in the xy-plane passes through the origin and has a slope of 1/7 is 7y = x.

In the given question, we have to find a line in the xy-plane passes through the origin and has a slope of 1/7.

The equation of the line is:

y - y(1) = m(x - x(1))

The given points is (0, 0). So

x(1) = 0 and y(1) = 0

From the given question, m = 1/7

Now putting the value in the equation of line

y - 0 = 1/7(x - 0)

y = 1/7 x

Multiply by 7 on both side, we get

7y = x

Hence, a line in the xy-plane passes through the origin and has a slope of 1/7 is 7y = x.
