Problem 18

Answers:

~P -> Q: "if it is not fall, then the leaves change colors"

~P -> ~Q: "if it is not fall, then the leaves don't change colors"

P -> ~Q: "If it is fall, then the leaves don't change colors"

Q -> ~P: "If the leaves change colors, then it is not fall"

----------

Explanation:

Simply replace each letter with the corresponding definition. We replace each P with "it is fall" and each ~P with "it is not fall". The squiggly line means "not". The same idea applies with Q and ~Q.

==========================================

Problem 19

Answer: Choice A) 134

----------

Explanation:

AB = CD

8x = 4x+24

8x-4x = 24

4x = 24

x = 6

BC = 18x+26

BC = 18*6+26

BC = 134

==========================================

Problem 20

Answer: Choice C) x = 5 and y = 11

----------

Explanation:

(anglePQR)+(angleRQS) = 90

(12x-2)+(6x+2) = 90

18x = 90

x = 5

angle TQU = 90

10y-20 = 90

10y = 110

y = 11

==========================================

Problem 21

Answer:  99

----------

Explanation:

The remote interior angles add to the exterior angle (remote interior angle theorem)

(angle RPQ) + (angle PQR) = angle PRS

(3x-29) + (7x-42) = 6x-3

10x-71 = 6x-3

10x-6x = -3+71

4x = 68

x = 68/4

x = 17

angle PRS = 6x-3

angle PRS = 6*17-3

angle PRS = 99

==========================================

Problem 22

Answer: 116

----------

Explanation:

Refer to the diagram below.

Solve 105+x = 180 to get x = 75

Solve 135+y = 180 to get y = 45

Solve x+y+z = 180 to get z = 60

Solve z+82+p = 180 to get p = 38

Solve p+78+q = 180 to get q = 64

Solve q+r = 180 to get r = 116

==========================================

Problem 23

Answer: B) between 4 and 44 inches

----------

Explanation:

We use a variation of the triangle inequality theorem here.

If p is the missing side length, then

24-20 < p < 24+20

4 < p < 44

So,

4 < XY < 44

The side XY cannot be 4 inches and it cannot be 44 inches either.

==========================================

Problem 24

4 Answers: A, B, C, D

----------

Explanation:

Same idea as problem 23

24-10 < x < 24+10

14 < x < 34

So we'll select values between 14 and 34, excluding each endpoint. Those values are x = 16, 18, 24, 26

In other words, only 12 and 34 are non-answers.

==========================================

Problem 25

Answer: C) 84 degrees

----------

Explanation:

The given exterior angle is 152 degrees

Subtract that from 180 to get the adjacent interior angle 180-152 = 28

Now let's find the missing angle of triangle DEB

D+E+B = 180

28+68+B = 180

96+B = 180

B = 180-96

B = 84

This is the measure of angle DBE

This is also the measure of angle ABC because the two angles are vertical angles.

Vertical angles are always congruent.

Answer:

Step-by-step explanation:

2x - 8 = 10

Bringing like terms on one side

2x = 10 + 8

2x = 18

x = 18/2 = 9

Answer:

x= 9 balance the equation

Step-by-step explanation:

2x-8=10 -------- equation (1)

2x=10+8 -------- equation (2)

2x=18

x = 9

let's put x = 9 into equation(2)

2(9) =10+8

18=18, x= 9 balance the equation

Answer:

4/3.

Step-by-step explanation:

Unit rate is the same as slope. In order to find the slope, we are going to use this formula:

m = y2 - y1 / x2 - x1

Now, we substitute the numbers into the equation:

m = 8 - 0 / 6 - 0

m = 8/6

m = 4/3

Therefore, the unit rate is 4/3.

Answer:

El hijo solo tardará 3 horas en arar el campo

Step-by-step explanation:

Aquí, se nos dice que ambos pasan dos horas para arar el campo mientras que el padre solo pasa 6 horas.

Queremos saber el tiempo que pasará el hijo si va a trabajar solo

Sea el área del campo x

La tasa de trabajo de ambos es x / 2

La tasa de trabajo del padre será x / 6 Deja que el tiempo que pasa el hijo sea y La tasa de trabajo del hijo es x / y

Sumando la tasa de trabajo del padre a la del hijo da la tasa de trabajo total de ambos Por lo tanto;

x / 6 + x / y = x / 2

Despegar x 1/6 + 1 /y = 1/2

1 / y = 1/2 - 1/6

1 / y= 1/3

entonces y = 3

El hijo solo tardará 3 horas en arar el campo.

Answer:

Angle between the lines of sight to A and B = 50.94°

Step-by-step explanation:

Distance between the cities A and B = 223 km

Distance between the cities  B and C = 285 km

Distance between the cities  A and C = 152 km

By applying cosine rule in triangle ABC,

AB² = AC² + BC² - 2(AC)(BC)CosC

(223)² = (152)² + (285)² - 2(152)(285)CosC

49729 = 23104 + 81225 - (86640)CosC

CosC = [tex]\frac{54600}{86640}[/tex]

CosC = 0.630194

C = [tex]\text{Cos}^{-1}(0.630194)[/tex]

C = 50.94°

Therefore, angle between the lines of sight to cities A and B is 50.94°

The ratio of brownies to donuts 22:21.

Given that, there are 2 cakes for every 7 donuts and 11 brownies for every 3 cakes.

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Now, ratio to cakes and donuts = 2:7

Ratio to brownies to cakes = 11:3

Multiply 3 to the ratio 2:7. That is 6:21.

Multiply 2 to the ratio 11:3. That is 22:6.

So, the ratio of brownies to donuts 22:21

Therefore, the ratio of brownies to donuts 22:21.

14.88 resmas

Step-by-step explanation:

Los maestros de una escuela planean enviar 6 boletines al año a cada una de las 620 familias con estudiantes en la escuela.

Esto significa: El número total de boletines que recibe cada familia = 6 × 620 familias

= La escuela envía 3720 boletines cada año

Cada uno de los boletines necesita 2 hojas de papel.

1 boletín = 2 hojas de papel

3720 boletines =

Cruz multiplicar

3720 boletines × 2 hojas

= Se necesitan 7440 hojas de papel en un año

El papel se vende en resmas de 500 hojas.

¿Cuál es la cantidad mínima de resmas de papel necesarias para imprimir los boletines escolares en un año?

500 hojas de papel = 1 resma

7440 hojas de papel = y

Cruz multiplicar

500 × y = 7440 × 1

y = 7440/500

y = 14.88 resmas

La cantidad mínima de resmas de papel necesarias para imprimir los boletines escolares en un año es 1488 resmas

Answer:

[tex]x=\frac{1}{2}[/tex]

Step-by-step explanation:

So we are given the equation:

y = 4x - 1

and we are asked to find the value of x when the value of y is 1.

In other words, what is x when y = 1? To find this, we can plug in 1 for y and solve for x.

1 = 4x - 1

Now solve for x. Add 1 to both sides.

2 = 4x

Divide both sides by 4.

[tex]x=\frac{1}{2}[/tex]

So now we have found that when the value of y is 1, the value of x is 1/2.

Joseph caught 7 tadpoles

Step-by-step explanation:

Let the number of tadpoles caught by Joseph be x

The number of tadpoles Wendy caught will be ;

9(x + 3)

After Joseph was upset, he released half of Wendy’s tadpole and then six times as many as Joseph caught swam away leaving Wendy with only three tadpoles left;

Hence, mathematically;

9(x + 3)/2 - 6x = 3

Multiply through be 2

9(x + 3) - 12x = 6

9x + 27 -12x = 6

9x -12x = 6-27

3x = 21

x = 21/3

Determine J"

When reflected over y axis:

[tex]J'(x,y) = J(-x,y)[/tex]

We have that:

[tex]J = (5,-3)[/tex]

So:

[tex]J(-x,y) = (-5,-3)[/tex]

Hence

[tex]J' = (-5,-3)[/tex]

When reflected over x axis:

[tex]J"(x,y) = J'(x,-y)[/tex]

We have that:

[tex]J' = (-5,-3)[/tex]
