A bag contains 2 red, 4 blue, and 4 yellow marbles. What is the probability of pulling a red marble, putting the marble back, and then pulling a blue marble?

Answer:

<H = 40

Step-by-step explanation:

Complementary angles add to 90 degrees

2x+10 + x+20 = 90

Combine like terms

3x+30 = 90

Subtract 30

3x+30 -30 = 90-30

3x = 60

Divide by 3

3x/3 = 60/3

x = 20

<H = x+20 = 20+20 = 40

Answer:

La madre hizo en total 2 y 3/8 litros de jugo.

Step-by-step explanation:

Sabemos que preparó:

3/4 litros de jugo de frutilla = 3/4 L

1 y 1/2 litro de jugo de manzana = (1 + 1/2) L  

1/8 litro de jugo de limón = 1/8 L  

1 y 1/2 litro de agua = (1 + 1/2) L  

¿Cuántos litros de jugo preparó la mamá?

Simplemente debemos sumar los distintos volúmenes de jugo escritos arriba (el de agua no, pues solo nos pregunta cuantos litros de jugo se prepararon)

Total de jugo = 3/4 L +  (1 + 1/2) L  + 1/8 L  

Para completar esta suma, separamos los números enteros de los racionales:

Total de jugo = 1 L + ( 3/4 + 1/2 + 1/8) L

Para resolver la suma dentro del paréntesis, debemos tener todos los números con el mismo denominador.

Recordar que si multiplicamos el numerador y el denominador por el mismo número, entonces el número racional no cambia.

Como el denominador más grande dentro del paréntesis es 8 (que tambien es multiplo de los otros dos), tratemos de reescribir los otros dos números de tal forma que su denominador también sea 8:

Total de jugo = 1 L + ( (2/2)*(3/4) +(4/4)*(1/2) + 1/8) L

                       = 1 L + (6/8 + 4/8 + 1/8) L

                       = 1 L + (11/8) L

podemos reescribir el segundo termino como:  

                        = 1L + (8 + 3)/8 L

                        = 1L + (8/8) L + (3/8) L

                         = 1L + 1L + 3/8 L

                          = 2L + 3/8 L

La madre hizo en total 2 y 3/8 litros de jugo.

Answer:

(-2,5)

Step-by-step explanation:

When a point is rotated  counterclockwise 90 degrees about the origin then the coordinates of the image will be (x,y) → (-y,x).

Here, (5,2)→(-2,5)

Therefore , if (5,2) is rotated counterclockwise 90 degrees about the origin its image will be point (-2,5).

Hence, if (5,2) is rotated counterclockwise 90 degrees about the origin its image will be point (-2,5).

Answer:

15.6km

Step-by-step explanation:

Given the map scale 1:200000

1cm on the map represents 200000 cm on ground or in actual distance

Hence, if distance from Belfast to Larne is 7.8vm on map ;

Actual distance will be :

7.8 * 200000 = 1560000 cm

Converting to km :

Recall :

1000 m = 1km

100 cm = 1 m

Hence,

100000 cm = 1km

Therefore, (1560000 / 100000) km

= 15.6km

Hence, distance between Belfast and Larne is 15.6km

Answer:

1. Melissa and Corey started on different trails.

2. Melissa hiked up the trail for a longer period of time than Corey.

3. Melissa and Corey crossed paths between 60 and 90 minutes.

4. Corey began his descent before Melissa.

Step-by-step explanation:

A. Melissa and Corey started on different trails. - TRUE

Rationale: at the start, when t = 0, Melissa hiking trail elevation was 8,342 ft while that of Corey was 10,004 ft. Therefore, they started on different trails.

B. Melissa hiked up the trail for a longer period of time than Corey. - TRUE

Rationale: It took Melissa 90 mins to reach the highest elevation of 12,921 while it took just 60 mins for Corey to teach same elevation height at 60 mins

C. Melissa and Corey crossed paths between 60 and 90 minutes. - TRUE

Rationale: As Melissa was still ascending between 60 - 90 mins from 11,239 to 12,921, Corey was descending at the same time . So their path crossed.

D. Corey began his descent before Melissa. - TRUE

Rationale: Corey started descending earlier at 60 mins before Melissa

E. As Melissa’s time increased from 0 to 60 minutes, her elevation decreased. - FALSE

Rationale: as Melissa's time increased from 0 to 60 mins, her elevation increased also from 8,342 ft to 11,239 ft.

Answer:

A) Melissa and Corey started on different trails.

B) Melissa hiked up the trail for a longer period of time than Corey.

D) Corey began his descent before Melissa.

Answer:

a) Martín recorrió más distancia, b) A Samuel, Martín y Santiago les falta 7.05, 7.55 y 7.883 kilómetros, respectivamente, c) La distancia recorrida promedio es 21.889 kilómetros, d) Martín recorrió 0.333 kilómetros más que Santiago.

Step-by-step explanation:

a) En primer lugar, convertimos la distancia recorrida por cada persona a su forma decimal:

Samuel

[tex]\frac{178}{8}\,km = 22.25\,km[/tex]

Martin

[tex]21\,km + \frac{3}{4}\,km = 21.75\,km[/tex]

Santiago

[tex]21\,km + \frac{5}{12}\,km = 21.417\,km[/tex]

Como puede apreciarse, Martín recorrió más distancia.

b) La distancia faltante es igual a la sustracción de la distancia recorrida por la persona a la distancia total:

Samuel

[tex]x = 29.3\,km -22.25\,km[/tex]

[tex]x = 7.05\,km[/tex]

Martin

[tex]x = 29.3\,km - 21.75\,km[/tex]

[tex]x = 7.55\,cm[/tex]

Santiago

[tex]x = 29.3\,km - 21.417\,km[/tex]

[tex]x = 7.883\,km[/tex]

A Samuel, Martín y Santiago les falta 7.05, 7.55 y 7.883 kilómetros, respectivamente.

c) La distancia recorrida promedio se obtiene sumando las distancias recorridas de las tres personas y dividiendo el resultado por la cantidad de personas:

[tex]\bar{x} = \frac{22.5\,km + 21.75\,km + 21.417\,km}{3}[/tex]

[tex]\bar x = 21.889\,km[/tex]

La distancia recorrida promedio es 21.889 kilómetros.

d) Esta diferencia se encuentra a restar la distancia recorrida por Santiago a la distancia recorrida por Martín:

[tex]x = 21.75\,km - 21.417\,km[/tex]

[tex]x = 0.333\,km[/tex]

Martín recorrió 0.333 kilómetros más que Santiago.

(from x=0 to x=2 it goes up by 5)

-2 is the intercept with the y-Axis

the general formula is:

y = m*x + b

where m is the slope and b the intercept

Answer:

x = 12

Step-by-step explanation:

Angle 1 = 8x - 17

Angle 2 = 5x + 19

These are congruent which means they are the same so the equation is:

8x - 17 = 5x + 19

3x - 17 = 19

3x = 36

x = 12

Answer:

last option is correct

Step-by-step explanation:

8x-17=5x+19(being corresponding angles)

8x-5x=19+17

3x=36

x=36/3

x=12

Answer:

16 flower pots

Step-by-step explanation:

Length of path = 12 m long

Flower pot is placed every 3/4 m along the path ;

Number of flower pots required = (length of path / length of distance placed)

Number of flower pots required = 12 ÷ 3/4

12 * 4/3 = (12 * 4) / 3 = 48 / 3 = 16 flower pots

Answer:

40 months

Step-by-step explanation:

It will take Vanessa 40 months or 3 years and 4 months to repay the bank their loan amount(without interest ofc).

Answer:

Time = 42 months

Step-by-step explanation:

[tex]Monthly \ payment = [rate + \frac{rate}{(1 + rate)^{month}-1}] \times principal[/tex]

Monthly payment = 300

Principal = 12000

[tex]Rate \% = \frac{300}{12000} \times 100 = \frac{30}{12} = \frac{5}{2} = 2.5[/tex]

Substituting and solving Months = 42 months

Answer:

C. Neither

Step-by-step explanation:

This is because the picture is showing both Exponential Growth AND Exponential Decay. As a result, it is both, but that is not an option, so neither is the answer. Hope it helps, and thank you for choosing Brainly for your question :D

Answer:

exponential decay

Step-by-step explanation:

We are multiplying by 1/3 each time

81 * 1/3 = 27

27*1/3 = 9

9*1/3 = 3

This is getting smaller so it is exponential decay

For question 2:

[tex]\to -5^{-3}=-\frac{1}{5^3}=-\frac{1}{5\times 5 \times 5}= -\frac{1}{125}\\\\[/tex]

For question 3:

Answer:

16022 square foot

Step-by-step explanation:

The world's largest cookie was baked in North Carolina in 2003. Its diameter was 100 feet and it contained about 6,000 pounds of chocolate chips! If the cookie was a cylinder 1 foot tall, and you wanted to cover it with icing, how many square inches would you have to ice? Use 3.14 for .

We find the surface area of the cylinder

= 2πr(r + h)

r = Diameter /2 = 100 feet/2

r = 50 feet

h = 1 feet

Hence

2 × 3.14 × 50(50 + 1)

= 16022.122533 square foot

= 16022 square foot

Answer:

53/100

Step-by-step explanation:

First, we convert the fraction to a decimal number by dividing the numerator by the denominator:

8 / 15 = 0.533

There are two parts to the decimal number above:

Integer Part: 0

Fractional Part: 533

Now, we will make the Fractional Part just two digits (nearest hundredth) by using our rounding rules.*

In this case, Rule I applies, so 8/15 (or 0.533) rounded to the nearest hundredth in decimal format is:

0.53

Next, we will make 8/15 rounded to the nearest hundredth in fraction format. Since you can divide our decimal format answer above by 1 and keep the same value, you can make it like this:

0.53 = 0.53/1

Then, we multiply the numerator and denominator by 100 to get rid of the decimal point:

(0.53 x 100) / (1 x 100) = 53/100

That's it. 8/15 rounded to the nearest hundredth is displayed below (simplified if necessary):

53/100
