Are these fractions equivalent or
nonequivalent?

Answer:

Step-by-step: The reason we cross multiply fractions is to compare them. Cross multiplying fractions tells us if two fractions are equal or which one is greater. This is especially useful when you are working with larger fractions that you aren't sure how to reduce.

Answer:

adding two fractions is different than multiplying two fractions bc after adding the fractions, you have to simplify them and it is not easy but with multiplying, you multiply from left to right.

Step-by-step explanation:

example: 1/2+3/4
4/8+6/8=10/8=1 1/4
another example: 6/10*4/6=24/60

Answer:

14/16 or 7/8.

Step-by-step explanation:

We know the total champions is 30. There are 16 boys, so to find the number of girls we can do 30-16. This gives us 14. Now we know that there are 16 boys and 14 girls, and the question is asking for the ratio of champions who are girls to the number who are boys. This means the ratio would simply be 14 to 16, for every 14 girls there are 16 boys. You can simply this ratio to 7 to 8, meaning for every 7 girls there are 8 boys.

Sales of Statin on January 1, 2008 was 22.2 billion dollars; and the year that the Statin sales reached 25.6 billion dollars was in 2010.

Given:

S = 1.7 x + 5.2 .............................. (1)

Sales of statin on January 1, 2008 can be calculated as follows:

x = 2008 - 1998 = 10

Substituting x = 10 into equation (1), we have:

S = (1.7 * 10) + 5.2

S = 17 + 5.2

S = 22.2

The answer above implies that sales of Statin on January 1, 2008 was 22.2 billion dollars.

The year that the Statin sales reached 25.6 billion dollars can be calculated as follows:

S = 25.6

Substituting S = 25.6 into equation (1) and solving for x, we have:

25.6 = 1.7x + 5.2

25.6 - 5.2 = 1.7x

20.4  = 1.7x

x = 20.4 / 1.7

x = 12

Therefore, we have:

The year Statin sales reached 25.6 billion = 1998 + x = 1998 + 12 = 2010

The sales of Statin on January 1, 2008 is 22.2 billion dollars and the year statin sales reached 25.6 billion was in 2010

Linear functions are equations that has a leading degree of 1.

Given the expression that represents amount of sales, S , of statin (in billions of dollars) x years after January 1, 1998 as;

S = 1.7 x + 5.2

For the sales of statin on January 1, 2008, this is calculated as

x = 2008 - 1998 = 10years

Substitute x = 10 into the given equation to have;

S = 1.7(10) + 5.2

S = 17 + 5.2

S = 22.2

Therefore the sales of Statin on January 1, 2008 is 22.2 billion dollars.

For the year that the Statin sales reached 25.6 billion dollar;

S(x) = 25.6

Substituting S = 25.6 into the equation

25.6 = 1.7x + 5.2

1.7x = 25.6 - 5.2

1.7x = 20.4

x = 12

Hence the year statin sales reached 25.6 billion was in 2010

The function f(x) = cos x crosses the x-axis at x₁ = - 0.5π and x₂ = - 1.5π.

Cosine function is a function bounded between - 1 and 1 and whose period is 2π, all the values of x such that the cosine function crosses the x-axis is described by the following expression:

cos x = 0        (1)

Then, by inverse trigonometric functions:

x = cos⁻¹ 0

x = 0.5π ± π · i, where i is a non-negative integer.

If we know that i = 1 and i = 2, then the values of x within the interval [- 2π, 0] are, respectively:

x₁ = - 0.5π, x₂ = - 1.5π

The number of burgers Steve can make = 18

In this question, Steve has 6 3/4 pounds of ground beef to make hamburgers for a party.

It takes 3/8 of ground beef to make a hamburger.

We need to find the number of burgers Steve can make.

First we convert the improper fraction 6 3/4 into a proper fraction.

6 3/4 = 27/4

For 1 hamburger 3/8 of ground beef is required.

Let n be the number of burgers Steve can make.

n = (27 / 4) / (3 / 8)

n = 27/4 × 8/3

n = 9 × 2

n = 18

Therefore, the number of burgers Steve can make = 18

The equation, in point-slope form, that represents the distance of Byron from home is: A. y - 4 = -6(x - 1/2).

An equation can be written in point-slope form, where m represents the slope and (a, b) represents a point on the line, as: y - b = m(x - a).

From the given information describing Bray's distance from home after some time, we have the following parameters:

Substitute m = -6 and (a, b) = (1/2, 4) into y - b = m(x - a):

y - 4 = -6(x - 1/2)

Therefore, the equation, in point-slope form, that represents the distance of Byron from home is: A. y - 4 = -6(x - 1/2).

The simplified radical form of the equation [tex](x^{4})^{\frac{5}{6} }[/tex] is [tex]x^{\frac{10}{3} }[/tex]

The exponentiation is written as [tex]a^{n}[/tex], where a is the base and n is the exponent or power. We say as "a by n". Exponent means the number of times the base is used as a factor.

The expression = [tex](x^{4})^{\frac{5}{6} }[/tex]

We know,

The power rules for the exponent [tex](a^{m})^{n}=a^{mn}[/tex]

Here multiply the exponent times the power.

Simplify it

[tex](x^{4})^{\frac{5}{6} }=(x)^{4(\frac{5}{6}) }[/tex]

Applying the distance formula to find the base and height of the triangle, the area of the triangle is calculated as: 17.85 units².

Area of triangle = 1/2(base)(height).

The base of triangle QRS is QS.

The height of triangle QRS is RT.

Use the distance formula [tex]\sqrt{(y_2 - y_1)^2 + (x_2 - x_1)^2}[/tex] to find the length of QS and RT:

Q(2, 4) = (x1, y1)

S(8, -2) = (x2, y2)

QS = √[(8−2)² + (−2−4)²]

QS = √72

QS ≈ 8.5 units

R(6, 6) = (x1, y1)

T(3, 3) = (x2, y2)

RT = √[(3−6)² + (3−6)²]

RT = √18

RT ≈ 4.2 units
