Answer:

That number is  9.77 x 10²² .

Step-by-step explanation:

Answer:

9.777 x 10^22

Step-by-step explanation:

in order to put a number in scientific notation, you have to move the invisible decimal over to the right since the number is a large number. in this case, the invisible decimal would start between 9 and 7. if you put this decimal to the right until you reach the last zero of the right, you would have move the decimal 22 spaces to the right

Answer:

1A 60. B 100. C. 80. 2. 84 / 75 / 77

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

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.

Answer:

a. Emily should begin her turn as the third driver at point (1, -0.5).

b. Emily's turn to drive end at point (-2.5, -3.75).

Step-by-step explanation:

Let assume that the group of girls travels from their hometown to San Antonio in a straight line. We know that each location is, respectively:

Hometown

[tex]H(x,y) = (8,6)[/tex]

San Antonio

[tex]T(x,y) = (-6,-7)[/tex]

Then, we can determine the end of each girl's turn to drive by the following vectorial expression based on the vectorial equation of the line:

Steph

[tex]S(x,y) = H(x,y) + \frac{1}{4}\cdot [T(x,y)-H(x,y)][/tex] (1)

[tex]S(x,y) = (8,6) + \frac{1}{4}\cdot [(-6,-7)-(8,6)][/tex]

[tex]S(x,y) = (8,6) +\frac{1}{4}\cdot (-14,-13)[/tex]

[tex]S(x,y) = (4.5,2.75)[/tex]

Andra

[tex]A(x,y) = H(x,y) + \frac{2}{4}\cdot [T(x,y)-H(x,y)][/tex] (2)

[tex]A(x,y) = (8,6) + \frac{2}{4}\cdot [(-6,-7)-(8,6)][/tex]

[tex]A(x,y) = (8,6)+\frac{2}{4}\cdot (-14,-13)[/tex]

[tex]A(x,y) =(1, -0.5)[/tex]

Emily

[tex]E(x,y) = H(x,y) + \frac{3}{4}\cdot [T(x,y)-H(x,y)][/tex] (3)

[tex]E(x,y) = (8,6) + \frac{3}{4}\cdot [(-6,-7)-(8,6)][/tex]

[tex]E(x,y) = (8,6)+\frac{3}{4}\cdot (-14,-13)[/tex]

[tex]E(x,y) = (-2.5, -3.75)[/tex]

a. If the girls take turns driving and each girl drives the same distance, at what point should they stop from Emily to begin her turn as the third driver?

Emily's beginning point is the Andra's stop point, that is, [tex]A(x,y) =(1, -0.5)[/tex].

Emily should begin her turn as the third driver at point (1, -0.5).

b. At what point does Emily's turn to drive end?

Emily's turn to drive end at point (-2.5, -3.75).

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

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.

Answer:

$29.67 each

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

89.01 divided by 3 = $29.67 each

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) .

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.

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

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
