Answer 1

Greetings from Brasil...

It is possible to answer this question through Determinant

| X     Y     1 |

| X₁    Y₁    1 |  = 0

| X₂    Y₂   1 |

We have:

(X₁; Y₁) = (-9; 8)

(X₂; Y₂) = (-3; -1)

then

| X   Y   1 |

| -9  8   1 |  = 0

| -3  -1   1 |

9X + 6Y + 33 = 0

Of the 30 champions of the National Spelling Bee from 1974 to 2003, 16 are boys. Find the ratio of the number of champions who are girls to the number who are boys.

Answers

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.

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

How to Write an Equation in Point-slope Form?

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:

x = hours (time)y = distance (miles)Slope (m) = -6A point = (1/2, 4)

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).

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 how many burgers can Steve make

Answers

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

Which inequality represents how many months (m) it will take Gabriela to save at least $5,600?
m < 6
m > 6
m ≤ 6
m ≥ 6

Answers

Inequality represents number of months (m) it will take Gabriela to save at least $5,600 is m ≥ 6.

As given in the question,

Amount Gabriela plans to save to buy a car = at least $5,600

Amount she already has = $2500

Amount she needs to save at least = $(5600 -2500)

                                                          =$3100

Plans to save each month =$500

Inequality to represents the number of months to save at least $5600

m ≥ 3100/500

⇒ m ≥ 6

Therefore, inequality represents number of months (m) it will take Gabriela to save at least $5,600 is m ≥ 6.

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]

=[tex]x^{\frac{20}{6} }[/tex]

Divide both 20 and 6 by 2 to make it to simplest form, then the result

calories

Answers

Answer:

A = 261 calories. and B = 251 calories

Step-by-step explanation:

A + 2B = 763

2A + B = 773

---------------------------

-2(A + 2B = 763)

-2A - 4B = - 1526

2A + B = 773

-----------------------------

-3B = - 753

B = 753/3

B = 251

Candy bar B has 251 calories

now let's find A

A + 2B = 763

A + 2 (251) = 763

A + 502 = 763

A = 763 - 502

A = 261

Candy bar A has 261 calories

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)

Sales of statin on January 1, 2008 was billion dollars. Statin sales reached 25.6 billion dollars in the year .

Answers

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.

How do we calculate sales and the year it occurred?

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

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
