p es el precio del libro

e es la cantidad que Paul tenía al inicio

Answer:

(9, 57/7)

Step-by-step explanation:

Given the coordinates A(5 , 5)  and B(19 , 16), divided by the point P in the ratio 5:2, to get the coordinate of P, we will use the formula;

P(X, Y) = {{ax1+bx2/a+b, ay1+by2/a+b}

X = ax1+bx2/a+b

Substitute the given values

X = 5(5)+2(19)/5+2

X = 25+38/7

X = 63/7

X = 9

Similarly;

Y = 5(5)+2(16)/5+2

Y = 25+32/7

Y = 57/7

Hence the coordinate of point P is (9, 57/7)

The sin A expressed in ratio form is [tex]\frac{\sqrt{6} }{4}[/tex]

Step-by-step explanation:

From the given right angled triangle diagram, sin A is calculated as follows;

[tex]sin \ A = \frac{Opp}{hypo} \\\\sin \ A = \frac{2\sqrt{6} }{8} \\\\sin \ A = \frac{\sqrt{6} }{4}[/tex]

Therefore, the sin A expressed in ratio form is [tex]\frac{\sqrt{6} }{4}[/tex]

Answer: $10,000

Step-by-step explanation:

Lanna's dad stock worth will be the value of the total shares in both company A and company B.

Value of stock in company A = 100 × $45 = $4500

Value of stock in company B = 250 × $22 = $5500

Total stock worth = $4500 + $5500 = $10,000

Answer:

12 fish are girls

Step-by-step explanation:

multiply 4/6 by 6 which would be 24/36. Then substract 24 from 36 and you get 12.

Answer:

12 are girls

Step-by-step explanation:

Reason that since 4/6 of them are boys then that means 2/6 are girls

then convert 2/6 to decimal form which is 0.3333....

then multiply that by 36 which gives us 12

you could also go the roundabout way and convert 4/6 to decimal form and take that value and multiply it by 36 which gives us 24 then subtract 24 from 36 which still gives us 12

hope this makes sense

Answer:

Janine is 28. Ingrid is 30.

Step-by-step explanation:

Let the ages be x and x + 2 for Janine and her sister, respectively.

x/7 + (x + 2)/3 = 14

Multiply both sides by the LCD, 21, to get rid of denominators.

21 * x/7 + 21 * (x + 2)/2 = 21 * 14

3x + 7(x + 2) = 294

3x + 7x + 14 = 294

10x = 280

x = 28

x + 2 = 30

Answer: Janine is 28. Ingrid is 30.

Answer:

Janine is 28 and Ingrid is 30.

Step-by-step explanation:

Let Janine's age be x years , then Ingrid's age is x+2 years.

From the given information we have the equation:

x/7 + (x + 2)/3 = 14

Multiplying through by the LCM of 3 and 7 (21),  we have:

3x + 7(x + 2) = 294

10x + 14 = 294

10x =  294-14 = 280

x = 28, so:

Janine is 28 and Ingrid is 30.

Answer:

When the slopes of lines a and b are multiplied, the product is −1.

Line a and line b intersect to form four right angles.

Step-by-step explanation:

Given

Perpendicular lines a and b

Required

Select the true statements

Represent the slope of line a with [tex]m_1[/tex] and the slope of b with [tex]m_2[/tex].

The condition for perpendicularity is:

[tex]m_1 * m_2 = -1[/tex]

Solving further:

[tex]m_1 = -\frac{1}{m_2}[/tex]

To solve further, we need to analyze each of the given options

(a) This is not true because the slope of perpendicular lines are not reciprocal

(b) This is also not true because perpendicular lines do not necessarily have to intersect at their midpoints

(c) This is true because of the condition stated above: [tex]m_1 * m_2 = -1[/tex]

(d) This is also true because perpendicular lines form right angles when they intersect

(e) This is not true because of the condition stated above: [tex]m_1 = -\frac{1}{m_2}[/tex]

(f) This is not true because of the condition stated above: [tex]m_1 = -\frac{1}{m_2}[/tex]

The product of the slope of the perpendicular lines is negative of one. Then the correct options are B and C.

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Lines a and b are perpendicular.

Then the product of the slope of the perpendicular lines is negative of one. That is given as

[tex]\rm m_1*m_2 = -1[/tex]

a.  The slopes of lines a and b are reciprocals Line a and line b intersect at their midpoints. This is false.

b.  When the slopes of lines a and b are multiplied, the product is −1. This is true.

c.  Line a and line b intersect to form four right angles. This is true.

d.  The slopes of lines a and b are equal. This is false.

e.  The slopes of lines a and b are opposites. This is false.

Answer:

We can write out 3! (three factorial) as 3x2x1, and we can write out 5! as 5x4x3x2x1. This means that, since 3x2x1 is on the top and the bottom of the fraction, it cancels out. This leaves us with 1 on top, and 4x5=20 on the bottom.

The option which is used to inscribe a square in a circle is option B

B. Construct a perpendicular bisector of the diameter of the circle

Step-by-step explanation:

The steps required to inscribe a square in a circle are;

1) Draw the circle using a compass

2) Draw the diameter of the circle, that passes through the center of the circle with a straight edge label the endpoint of the diameter X and Y

3) Construct the line perpendicular to the diameter of the circle and label the endpoints as A and B

The figure formed by joining the endpoints X, Y, A, and B is the inscribed square of the circle

Therefore, the correct option is to construct a perpendicular bisector of the diameter of the circle.

Answer:

19

Step-by-step explanation:

Rearranging the number in ascending order,

12,15,17,19,19,20,24,26

Median = The average of the 4th and 5th number

[tex] = \frac{19 + 19}{2} \\ = 19[/tex]

Answer:

19

Step-by-step explanation:

so first you have to order the values from least to greatest.

12, 15, 17, 19, 19, 20, 24, 26

there are 8 terms (note that 2 of them are 19)

n = 8

median = (n + 1) ÷ 2

            =(8 + 1)/2

            =9/2 = 4.5

it's 19 because the median falls between those two (19) data points.

Answer:

1. m = 65°

x = 30°

2. x = 40°

Step-by-step explanation:

1. Since the figure is an isosceles triangle, m = 2x - 5

180 - 50 = 130 (Total degree for both m and 2x - 5)

130 ÷ 2 = 65 (m and 2x - 5 angle degrees)

65 - 5 = 60 (2x)

2 x = 60°

x = 60 ÷ 2 = 30°

2. I forgot the parallel rule for question 2, but I think X and 40° is parallel to each other?
