Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 3/7 is 7/3) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step, the fraction result cannot be further simplified by canceling.

120.3×2.2= 264.66

David weight his next weightlifting competition would be 264.66 pounds

Used the concept of measurement unit which states that,

A measurement unit is a standard quality used to express a physical quantity. Also, it refers to the comparison between the unknown quantity with the known quantity.

Given that,

David is traveling to the United States for his next weightlifting competition.

And, His weighs 120.3 kilograms.

Now, Change the weight into pounds as,

1 kg = 2.2 lb

Hence, it can be,

120.3 kg = 120.3 × 2.2 lb

= 264.66 pounds

Finding the halfway point is very needful because; it means that we can find the amount of flour used for 1 while egg.

We are told there is a need to find the Number that is halfway between 0 and 1½.

Now, halfway between 0 and 1½ is;

(0 + 1½)/2 = ¾

Now, we see that this halfway point which is ¾ is for the cup of flour and it is important to calculate it because number of eggs are in even whole numbers of 0, 2, 4 but finding the halfway point means that we can find the amount of flour for 1 egg.

Given:

Number of rows = 3

Number of columns = 6

Number of square boxes = 18

yellow square boxes in the top two rows = 12

Blue square boxes in the first 5 columns = 15

Number of green boxes (shading overlaps) = 10

To find:

The model to show multiplying a fraction by a fraction.

Solution:

2 rows out of 3 are shaded yellow.

Fraction for yellow = \(\dfrac{2}{3}\)

5 columns out of 6 are shaded blue.

Faction for blue = \(\dfrac{5}{6}\)

10 out of 18 squares are green.

Faction for green =  \(\dfrac{10}{18}=\dfrac{5}{9}\)

Now,

\(\dfrac{2}{3}\times \dfrac{5}{6}=\dfrac{10}{18}\)

\(\dfrac{2}{3}\times \dfrac{5}{6}=\dfrac{5}{9}\)

Therefore, the correct option is D.

The correct option is D.

2 rows out of 3 are shaded yellow.

Fraction should be \(2\div 3\)

Now

5 columns out of 6 are shaded blue.

Fraction should be \(5 \div 6\)

And,

Hence the correct option is C and D

The following steps can be used  in order to determine the number of simulations:

Remember the maximum number of trials gives the maximum chance to produce results that are closest to the actual probability.

There is no one-size-fits-all answer to the question of which number of simulation trials is best.

However, in general, a larger number of trials is likely to produce more accurate results. So, options C or D (20 or 15) may be more likely to produce results that are closest to the actual probability.

Step-by-step explanation:

One of the Answers is C

Answer:

I believe it is D

Step-by-step explanation:

We can first multiply the 2 and 4 together to get 8.

Wow we already eliminated A.

When you have negative powers, you can just replace it with their inverse and turn the power positive.

For example, 2 to the power of -3  (2 ^ -3) can be replaced by 1/2 to the power of 3 (1/2^-3).

So we now have 8  (x^4 / yx^2

We can then just subtract the x's power of 2, because when dividing exponents with the same variable or base, we can just subtract them.

For example, x^5  divided by x ^ 2 has the same base/ variable of x, and you can subtract the 5 by 2 to get x^3.

So we have 8 ( x^2y)

So 8x^2 y

If function f(x) = 2x2 + 3x – 1 and g(x) = -x, then f(-1)+g( - 1) = -1

To solve this problem, we need to plug in -1 for x in both f(x) and g(x).

f(-1) = 2(-1)2 + 3(-1) – 1 = 2 - 3 - 1 = -2

g(-1) = -(-1) = 1

Now, we can add f(-1) and g(-1):

f(-1) + g(-1) = -2 + 1 = -1


To solve f(-1) + g(-1), we need to first find the values of f(-1) and g(-1) individually.

For f(-1):
f(x) = 2x^2 + 3x - 1
f(-1) = 2(-1)^2 + 3(-1) - 1
f(-1) = 2(1) - 3 - 1
f(-1) = 2 - 3 - 1
f(-1) = -2

For g(-1):
g(x) = -x
g(-1) = -(-1)
g(-1) = 1

Now, let's add f(-1) and g(-1):

Answer:

a = 2, b = - 3, c = - 8

Step-by-step explanation:

Expand f(x) = a(x + b)² + c and compare coefficients of like terms, that is

a(x + b)² + c ← expand (x + b)² using FOIL

= a(x² + 2bx + b²) + c ← distribute parenthesis by a

= ax² + 2abx + ab² + c

Compare like terms with f(x) = 2x² - 12x + 10

Compare coefficients x² term

a = 2

Compare coefficients of x- term

2ab = - 12, substitute a = 2

2(2)b = - 12

4b = - 12 ( divide both sides by 4 )

b = - 3

Compare constant term

ab² + c = 10 , substitute a = 2, b = - 3

2(- 3)² + c = 10

18 + c = 10 ( subtract 18 from both sides )

c = - 8

Then a = 2, b = - 3, c = - 8

Sentence Fram: I found x-intercept by substitute y by 0 and I found y-intercept by substitute x by 0

x-intercept = (6, 0), y-intercept = (0, -3) ⇒ C

Step-by-step explanation:

∵ The equation of the graph is 6x - 12y = 36

→ Equate y by 0 to find x

∵ y = 0

∴ 6x - 12(0) = 36

∴ 6x - 0 = 36

∴ 6x = 36

→ Divide both sides by 6 to find x

∴ x = 6

∴ The x-intercept = (6, 0)

→ Equate x by 0 to find y

∵ x = 0

∴ 6(0) - 12y = 36

∴ 0 - 12y = 36

∴ -12y = 36

→ Divide both sides by -12 to find y

∴ y = -3

∴ The y-intercept = (0, -3)

∴ Sentence Fram: I found x-intercept by substitute y by 0 and I found

   y-intercept by substitute x by 0

∴ x-intercept = (6, 0), y-intercept = (0, -3)

Answer:

Reyna Puti sold = 20 bottles

Step-by-step explanation:

Silver duck = Php 10 per bottle

Reyna Puti = Php 15 per bottle

Silver duck sold = 30 bottles

Reyna Puti sold = x bottles

Total sales = Php 600.00

Total = cost of Silver duck * number sold + cost of Reyna Puti * number sold

600 = 10 * 30 + 15 * x

600 = 300 + 15x

Domain: {x | x is a real number}

Option D, "{x | x is a real number}" accurately represents the domain of the function.

The domain of the step function f(x) = [2x] - 1, where [2x] represents the greatest integer less than or equal to 2x, can be determined by considering the restrictions on the input values.

In this case, the step function is defined for all real numbers. However, the greatest integer function imposes a restriction. Since the greatest integer function only outputs integers, the input values (2x) must be such that they produce integer outputs.

For any real number x, the greatest integer less than or equal to 2x will always be an integer. Therefore, the domain of the function f(x) = [2x] - 1 is:

The equation is given, N(a) = 2.925 sin ( 3.65 ) + 12.18, which models the number of hours of daylight in New York City d days after March 21, 2010.

To solve the equation 11.5 = 2.925 sin (27 d) + 12.18 over the interval [0°, 720°), we need to isolate the sine function on one side of the equation.

Subtracting 12.18 from both sides, we get:
-0.68 = 2.925 sin (27 d)
Dividing both sides by 2.925, we get:
sin (27 d) = -0.2333
To find d, we need to use the inverse sine function (\(sin^{-1}\)) on both sides:
27 d = \(sin^{-1}\) (-0.2333)
Using a calculator, we find that \(sin^{-1}\) (-0.2333) = -13.5° or -0.235 radians (rounded to three decimal places).
Dividing both sides by 27, we get:
d = -0.0087 radians / 27
d = -0.00032 radians (rounded to five decimal places)
To make sense of this answer in the context of the problem, we need to convert radians to days.
One complete cycle of the sine function occurs over 360 degrees or 2π radians. Therefore, over the interval [0°, 720°), there are two complete cycles or 4π radians.
To find the number of days, we can set up a proportion:
4π radians = 365 days - 80 days (March 21 to June 9)
Solving for one radian, we get:
1 radian = (365 - 80) days / 4π
1 radian ≈ 71.3 days
Substituting this value, we get:
d = -0.00032 radians x 71.3 days/radian
d ≈ -0.023 days

Answer:

y = -(3/5)x - 6

Step-by-step explanation:

Lets look for an equation of the form y=mx+b, where m is the slope and b the y-intercept(the value of y when x=0).  We are given a reference line of 3x+5y = 15.  Let's rearrange that into standard form:

3x+5y = 15

5y = -3x+15

y = -(3/5)x+3

This tells us that the slope of the reference line is -(3/5).  Parallel lines have the same slope.

So we know the new line must use m = -(3/5) to be parallel.

This leads to:

 y = -(3/5)x + b

Any value of b will still result in a parallel line.  But we want OUR parallel line to go through point (-5,-3).  To find a value of b that would make that happen, enter the given point into the above equation:

y = -(3/5)x + b

(-3) = -(3/5)(-5) + b  for point (-5,-3)

Now solve for b:

(-3) = -(3/5)(-5) + b

(-3) = 3 + b

b = -6

The parallel line that goes through point (-5,-3) is y = -(3/5)x - 6
