You have eight more dogs than cats. You have 2 fewer chickens than dogs. You have three fewer guinea pigs than cats. If you have a total of 59 pets, write an equation that would help you find how many of each pet you have. Describe what the variable represents (Let __ represent...).

Answers

Answer 1

Answer:

read the answers below.

Step-by-step explanation:

d = dog

d = c + 8

ch = chickens

ch = d -2

gp = guinia pigs

gp = c - 3

d + c + ch + gp = 59

gp = c- 3

gp = d -8 - 3

gp = d - 11

d + d-8 + d - 2 + d-11 = 59

4d -8 - 2 - 11 = 59

4d - 21 = 59

4d - 21 + 21 = 59 + 21

4d = 80

4d/4 = 80/4

d = 20

========

c = d - 8

c = 20 - 8

c = 12

========

ch = d - 2

ch = 20 - 2

ch = 18

=========

gp = d - 11

gp = 20 - 11

gp = 9

Answers

Answer:

C) 10

Step-by-step explanation:

The triangle on the right shows that the side AB is 4 and the triangle on the left shows that the side DE is 8. Based on these two numbers I can conclude that the triangle DEF is double the size of triangle ABC. With this information, I can find e by doing 5*2=e and get 10 as my answer.

What is the value of a?

Answers

Answer:

a = 43°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180, that is

a + 8 + 2a + 43 = 180

3a + 51 = 180 ( subtract 51 from both sides )

3a = 129 ( divide both sides by 3 )

a = 43

− 3/4 is a rational number, but not an integer. Explain why below.

Answers

A rational number is any number that can be expressed as a fraction. An integer is a whole number. -3/4 is a fraction but not a whole number, so it is rational but not an integer.

− 3/4 is not an integer but a a rational number.

Why is this correct?

A rational number is simply a number that can be written as a fraction with both the numerator and denominator being integers (where the denominator's not zero). For instance lets consider 3/4 as an example. It can be expressed as the fraction 3/4, where 3 and 4 are both integers.

On the hand an integer is a number that is not, in the form of a fraction. In the case of 3/4 it cannot be classified as an integer since it represents a fraction, than a whole number.

If you roll a number cube 60 times and use the results to calculate the experimental probability of rolling a 1, the experimental probability of rolling a 1 will _____ be less than the theoretical probability of rolling a 1.

Answers

Answer:

sometimes

Step-by-step explanation:

Theoretical probability is fixed/remains the same because it is based on theory which is calculated, while the experimental probability is based on data that is gained from actually doing it. According to the law of large numbers, the average experimental probability always approaches the theoretical probability.

Step-by-step explanation:

6.75% of $72.50 = $4.90

72.50 + 4.90 = $77.40

15% of 77.40 = 11.61

77.40 + 11.61 = 89.01

Select the correct answer. Which equation represents the vertical line passing through (1,-9)? A x=-9 B. X= 1 C. y=-9 D y=1 Reset

Answers

Answer:

x = 1

Step-by-step explanation:

the vertical line is passing through only the x-axis and not the y axis. So the graph is a x = ? All you e have to to is to look for the x coordinate of the point the vertical line is passing through which is 1 and so the answer is x = 1.

Please mark brainliest. Thanks!!!!

x=1 represents the vertical line passing through (1,-9) .

What is vertical line ?

A vertical line is a line, parallel to y-axis and goes straight, up and down, in a coordinate plane.

In a vertical line x-coordinate remain constant, only y-coordinate changes.

The vertical lines are parallel to the y-axis and are perpendicular to the horizontal lines. On a vertical line, all the points on the line have the same x-coordinate.

Here x=1 is the only vertical line which passes through (1,-9) So option B is correct.

Mike spent half of his allowance playing acrade games his parents let him wash the gutters for 5.80 if he ended with 12.20 what is his weekly allowance

Answers

Answer:

Weekly allowance (W) = 12.80

Step-by-step explanation:

Given:

Ended amount = 12.20

Amount for guitar wash = 5.80

Find:

Weekly allowance (W)

Computation:

W + 5.80 - W/2 = 12.20

W + 5.80 - 0.5W = 12.20

0.5 W = 6.4

Weekly allowance (W) = 12.80

La Corona que herón mando elaborar tenía una masa de 1.5 kg y ocupaba un volumen de 300 cm ¿Era de oro dicha Corona? (Obten la respuesta utilizando el principio de arquímedes)

Answers

Answer:

Esta no es una corona de oro porque la densidad del oro es de 19,3 g / cm ^ 3

Step-by-step explanation:

La densidad de la corona se puede obtener del principio de Arquímedes.

Arquímedes descubrió que la fuerza de empuje hacia arriba sobre un sólido es igual al peso del fluido desplazado. entonces, cuando insertamos la corona en un cilindro de medición con un volumen específico, el volumen de agua desplazado es el volumen de la corona.

Dado que tenemos el volumen de la corona como 300 cm ^ 3 y su masa como 1,5 Kg.

La densidad de la corona = 1500 g / 300 cm ^ 3 = 5 g / cm ^ 3

Esta no es una corona de oro porque la densidad del oro es de 19,3 g / cm ^ 3

Conociendo la masa y el volumen de la corona de Herón, queremos saber si esta estaba hecha de oro o no.

Veremos que los datos proporcionados no coinciden con los que tendría el oro puro.

Sabemos que cada material conocido tiene una dada densidad a una dada temperatura. (Donde densidad es el cociente entre masa y volumen)

Particularmente, sabemos qe el oro tiene una densidad de 19.300 kg/m^3

En este caso, sabemos que la corona tiene una masa de 1.5kg y un volumen de 300cm^3

Notar que las unidades de volumen son diferentes, por lo que devemos cambiarlas:

1m = 100cm

entonces:

1cm = 0.01m

(1cm)^3 = 1cm^3 = (0.01m)^3

Entonces tendremos:

V = 300cm^3 = 0.000001*300 m^3 = 0.0003 m^3

Ahora podemos calcular la densidad como:

D = masa/volumen = 1.5kg/0.0003 m^3 = 5000 kg/m^3

Notar que esto es un tercio de la densidad del oro, asi que no, esto no es oro.

Μ ± 1σ of the observations lie between what two values? Lower Value Upper Value b. Μ ± 2σ of the observations lie between what two values? Lower Value Upper Value c. Μ ± 3σ of the observations lie between what two values? Lower Value Upper Value

Answers

Answer:

A.)

Lower Value = 295

Upper Value = 485

B.)

Lower Value = 200

Upper Value = 580

C.)

Lower Value = 105

Upper Value = 675

Step-by-step explanation:

Given that mean (M) = 390

Standard deviation (σ) = 95

Lower Value = mean value - number of standard deviations specified

Upper Value = mean value + number of standard deviations specified

a. Μ ± 1σ of the observations lie between what two values?

Lower Value = 390 - 1(95) = 295

Upper Value = 390 + 1(95) = 485

b. Μ ± 2σ of the observations lie between what two values?

Lower Value = 390 - 2(95) = 200

Upper Value = 390 + 2(95) = 580

c. Μ ± 3σ of the observations lie between what two values?

Lower Value = 390 - 3(95) = 105

Upper Value = 390 + 3(95) = 675
