How does -1.125 + 1.2 = 0.075 instead of 0.925?

Answer:

23rd hours

Step-by-step explanation:

This is problem based on arithmetic progression in which our first term is 45 , and the common difference is -2

we have to find the n when the nth term is 2.

The formula for nth term of an AP is

[tex]a_{n}=a+(n-1)d[/tex]

replacing the  values in the formula

[tex]a_{n}=a+(n-1)d\\2=45+(n-1)(-2)\\2=45-2(n-1)\\-43=-2(n-1)\\21.5 = n-1\\n=22.5\\[/tex]

hence at 22.5 hours it will reach 2F or we can say that after 23 hours the temperature will be below 2F

For this case we must find the product of the following expression:

[tex]\sqrt [3] {5} * \sqrt {2}[/tex]

By definition of properties of powers and roots we have:

[tex]\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}[/tex]

40°

Step-by-step explanation:

In any circle the following ratios are equal

let x be the measure of the central angle, then

[tex]\frac{arc}{circumference}[/tex] = [tex]\frac{x}{360}[/tex]

circumference = 2πr = 2π × 18 = 36π, so

[tex]\frac{4\pi }{36\pi }[/tex] = [tex]\frac{x}{360}[/tex], that is

[tex]\frac{1}{9}[/tex] = [tex]\frac{x}{360}[/tex] ( cross- multiply )

9x = 360 ( divide both sides by 9 )

x = 40

Hence central angle = 40°

Answer:(x^2+y^2)^2=(x^2+y^2)(x^2+y^2)

Step-by-step explanation:

We can rewrite left side into right side form

(x^2+y^2)^2=(x^2+y^2)(x^2+y^2)

we can expand it

(x^2+y^2)^2=x^4+x^2y^2+x^2y^2+y^4

(x^2+y^2)^2=x^4+y^4+2x^2y^2

we can add and subtract 2x^2y^2

(x^2+y^2)^2=x^4+y^4+2x^2y^2+2x^2y^2-2x^2y^2

(x^2+y^2)^2=x^4-2x^2y^2+y^4+2x^2y^2+2x^2y^2

(x^2+y^2)^2=x^4-2x^2y^2+y^4+4x^2y^2

(x^2+y^2)^2=x^4-2x^2y^2+y^4+(2xy)^2

(x^2+y^2)^2=(x^2-y^2)^2+(2xy)^2

The Pythagorean triple generator typically involves an algebraic formula where variables m and n are used to generate the sides of a right triangle such that a^2 + b^2 = c^2, with a common formula being a = m^2 - n^2, b = 2mn, and c = m^2 + n^2 for positive integers m and n.

The form of the Pythagorean triple generator refers to a set of algebraic formulas that produce Pythagorean triples, which are sets of three positive integers (a, b, c) that satisfy the condition of the Pythagorean theorem (a^2 + b^2 = c^2) for a right triangle.

One well-known formula to generate these triples is given by:

where m and n are positive integers with m > n. This formula will produce a Pythagorean triple as long as m and n are coprime and not both odd. It's important to note that not all Pythagorean triples can be generated by this formula, but it is a very common method of finding such triples.

Answer:

2x(x - 6)(x + 1)

Step-by-step explanation:

Given

2x³ - 10x² - 12x ← factor out 2x from each term

= 2x(x² - 5x - 6)

To factor the quadratic

Consider the factors of the constant term (- 6) which sum to give the coefficient of the x- term (- 5)

The factors are - 6 and + 1, since

- 6 × 1 = - 6 and - 6 + 1 = - 5, thus

x² - 5x - 6 = (x - 6)(x + 1) and

2x³ - 10x² - 12x = 2x(x - 6)(x + 1) ← in factored form

Step-by-step explanation:

The volume of a prism is:

V = AH

where A is the area of the base and H is the height.

The base is a triangle, so the area is:

A = 1/2 b h

We know that b = 3.  To find h, we can split the triangle in half.  Then we can either use Pythagorean theorem to find h, or properties of a 30-60-90 triangle.

The short leg is 3/2, so the height is 3/2 √3.

A = 1/2 (3) (3/2 √3)

A = 9/4 √3

Therefore:

V = (9/4 √3) (6)

V = 27/2 √3

Approximately 18.42% of the beef production annually worldwide comes from the U.S.

In the U.S., 12.0 million metric tons of beef are produced annually, while worldwide beef production is 65.1 million metric tons.

To find the percentage of beef produced in the U.S. compared to worldwide production, you can divide the U.S. beef production by the worldwide beef production and multiply by 100.

Percentage = ( U.S. beef production / Worldwide beef production ) x 100 = ( 12.0 million / 65.1 million ) x 100 = 18.42%.

Therefore, approximately 18.42% of the beef produced annually in the world is from the U.S.

Answer:

12 days

Step-by-step explanation:

Sally has  pet snail that fell into a well.

Depth of the well = 16 feet

Snail climbs up 5 feet but each night it slides back down 4 feet.

So the snail climbs up per day = 5 feet - 4 feet = 1 feet.

Number of days snail took to reach at 11 feet = 11 × 1 = 11 feet

Remaining distance to cover by the snail = 16 - 11 = 5 feet

Number of days to cover remaining 5 feet to reach the top of the well = 1 day

Therefore, snail will take 12 days to reach the top of the well.

Final answer:

The snail climbs up 5 feet and slides back 4 feet each day in a 16-foot deep well. With a net gain of 1 foot per day, the snail will escape on the 16th day after reaching the top without sliding back.

Explanation:

Sally's pet snail finds itself in a classic mathematical problem often associated with algebra and arithmetic sequences. The snail is attempting to escape a 16-foot deep well by climbing up 5 feet during the day and sliding back 4 feet each night. To determine how many days it will take for the snail to get out, we need to calculate the net progress made by the snail each day and then examine how this applies on the final day of the snail's ascent.

Each day, the snail makes a net gain of 1 foot (5 feet up during the day minus 4 feet down at night). After 15 days, the snail would have climbed 15 feet during the day. On the 16th day, the snail climbs up 5 feet and reaches the top of the well, coming out without sliding back down since it already reached the goal during daylight. Therefore, it will take the snail a total of 16 days to escape the well.

The prime factorizations of the numbers are

[tex]110 = 2\times 5 \times 11,\quad 40= 2^3\times 5,\quad 120=2^3\times 3\times 5[/tex]

The greatest common factor is composed by all common primes, taken with the lowest exponent possible. In this case, it will be

Answer:

your line goes through both (0,6) and (12,0)

Step-by-step explanation:

Ok so you are describing some lines you see I think:

I see some of these as points you mentioned:

(0,6)  ,  (0,-6)  , (6,0)

So let's see which of these work:

(0,6)?

2(0)+4(6)=24

        24=24

(0,6) does work!

The other point you have listed with (0,6) is (12,0).

Let's try (12,0)

2(12)+4(0)=24

24+0=24

24=24

(12,0) works!

So your line goes through both (0,6) and (12,0)

Answer:

The correct option is A) Line through the point (0,6) and (12,0).

Step-by-step explanation:

Consider the provided equation 2x + 4y = 24.

Substitute x = 0 in the provided equation.

2x + 4y = 24

2(0) + 4y = 24

4y = 24

y = 6

Thus, the points which satisfy the equation is (0,6).

Now, substitute x = 12 in the provided equation.

2x + 4y = 24

2(12) + 4y = 24

24 + 4y = 24

4y = 0

y = 0

Thus, the points which satisfy the equation is (12,0).

Therefore, the correct option is A) Line through the point (0,6) and (12,0).
