Jose unlocks his cellphone by placing his right thumb on a square of 1 centimeter by 1 centimeter at the center of the screen. Upon recognizing his thumbprint, the square expands outward. The cellphone unlocks when the perimeter reaches 32 centimeters, taking a total of 2.5 seconds. What is the perimeter of the square after 1.5 seconds? How is the answer 20.8?

Answer:

Number of hot chocolate = 250

Number of coffee = 25

Step-by-step explanation:

Given:

Total income = $200 = 20,000 cents

Number of total item sell = 275

Amount of each hot chocolate = 75 cents

Amount of each coffee = 50 cents

Find:

Number of each drink sold

Computation:

Assume

Number of hot chocolate = x

Number of coffee = 275 - x

So,

Total income = [Number of hot chocolate][Amount of each hot chocolate] + [Number of coffee][Amount of each coffee]

20,000 = [x][75] + [275-x][50]

20,000 = 75x + 13,750 - 50x

x = 250

Number of hot chocolate = 250

Number of coffee = 275 - 250

Number of coffee = 25

Answer: 250 Hot chocolates 25 Coffee

Step-by-step explanation:

Area of a circle ( A ) = 32 π units

Radius of a circle ( r ) = ?

Perimeter of a circle ( P ) = ?

First ,finding the radius of a circle :

[tex] \boxed{ \sf{area \: of \: a \: circle = \: \pi \: {r}^{2} }}[/tex]

[tex] \dashrightarrow{ \sf{32 \: \pi= \: \frac{22}{7} \times {r}^{2} }}[/tex]

[tex] \dashrightarrow{ \sf{32\pi \: = 3.14 {r}^{2} }}[/tex]

[tex] \dashrightarrow{ \sf{3.14 {r}^{2} = 32\pi}}[/tex]

[tex] \dashrightarrow{ \sf{ \frac{3.14 {r}^{2} }{3.14} = \frac{32\pi}{3.14} }}[/tex]

[tex] \dashrightarrow{ \sf{ {r}^{2} = 10.19 \: \pi \: }}[/tex]

[tex] \dashrightarrow{ \sf{r = \sqrt{10.19\pi} }}[/tex]

[tex] \dashrightarrow{ \sf{r = 3.19\pi}}[/tex]

Finding the perimeter of a circle ( P )

The perimeter of the circle with an area of 32 π square units is 2√32π units.

Given,

The area of a circle is 32 π square units.

We need to find its perimeter.

The area of a circle is given by:

= π r²

The perimeter of a circle is given by:

= 2πr

Where r = radius

Find the area of a circle.

Area = π r²

32 π  = π r²

Divide both sides by π

32 = r²

r = ±√32

r can not be negative so we have,

r = √32

Find the perimeter of a circle.

P = 2πr

P = 2 x π x √32

P = 2√32 π units

The perimeter of the circle with an area of 32 π square units is 2√32π units.

The rays represented in the diagram includes

Ray AB, NB, BN, BA

The vertex where rays NB and NA meets = N

Step-by-step explanation:

A ray is a line segment that extends endlessly from a given point. A ray is a line that has unbounded endpoint but has a start or endpoint.

A vertex is the point or corner which is the meeting point of two or more lines or rays. In the question, the meeting point of the rays NB and NA is the point N, which can be said to be the vertex of the two rays.

Answer:

(a) The next 3 terms in the sequence are 17, -31, and 65

(b) The 3 terms that came before -7 are 2, -1, and 5

Step-by-step explanation:

a. To determine the next 3 terms in the sequence after -7,

From the question, the sequence follows the rule: multiply the previous number by-2 and add 3.

Then, for the next number after -7, we will get

-7 × -2 = 14; 14 + 3 = 17

For the second number after -7, we will get

17 × -2 = -34; -34 + 3 = -31

For the third number after -7, we will get

-31 × -2 = 62; 62 + 3 = 65

Hence, the next 3 terms are 17, -31, and 65

(b) For the 3 terms that came before -7 in the sequence, the rule will be reversed, that is: subtract 3 from the immediate number and divide by -2

Hence, the previous number to -7 (that is, the third term in the sequence)

-7 -3 = -10; -10 ÷ -2 = 5

Then, the second term will be

5 - 3 = 2; 2 ÷ -2 = -1

and the first term will be

-1 -3 = -4; -4 ÷ -2 = 2

Hence, the 3 terms that came before -7 are 2, -1, and 5

 So the probability of drawing a second red marble is 8 out 10 or 0.8.

Step-by-step explanation:

It seems to me that if one red marble is already gone, there are 8 red marbles left out of a total of 10 marbles.

So the probability of drawing a second red marble is 8 out 10 or 0.8.

Answer:

8/10 or 4/5 or 0.8

Step-by-step explanation:

since one red marble is already taken, there are only eight remaining now and the total number of marbles are ten now. So you have to divide.

Therefore, the probability is 8/10 or 4/5 or 0.8.

Step-by-step explanation:

We are given the equation 6/33 = 24/x. We would like to solve for x.

To get rid of the fractions, let's multiply both sides by 33x:

(6/33) * 33x = (24/x) * 33x

6x = 24 * 33 = 792

Divide by 6 from both sides:

x = 792/6 = 132

Thus, x = 132.

Answer:

Hay 403 chicas que disfrutan las matemáticas en este colegio.

Step-by-step explanation:

Podemos obtener las siguientes pistas tras una lectura cuidadosa del enunciado:

1) Existen 627 alumnos entre hombres y mujeres en el colegio.

2) La cantidad de chicas es el duplo de la cantidad de chicos.

3) Solo a 15 chicas les disgusta las matemáticas.

Matemáticamente hablando, podemos construir las siguientes tres fórmulas:

[tex]x+y = 627[/tex] (1)

[tex]y = 2\cdot x[/tex] (2)

[tex]m = y - 15[/tex] (3)

Donde:

[tex]x[/tex] - Cantidad de chicos en el colegio, adimensional.

[tex]y[/tex] - Cantidad de chicas en el colegio, adimensional.

[tex]m[/tex] - Cantidad de chicas que disfrutan de las matemáticas en el colegio, adimensional.

Al eliminarse [tex]y[/tex] en (1), se puede hallar la cantidad de chicos en el colegio:

[tex]x + 2\cdot x = 627[/tex]

[tex]3\cdot x = 627[/tex]

[tex]x = 209[/tex]

Hay 209 chicos en el colegio.

Por (2) podemos determinar la cantidad de chicas:

[tex]y = 2\cdot (209)[/tex]

[tex]y = 418[/tex]

Hay 418 chicas en el colegio.

Finalmente, se calcula la cantidad de chicas del colegio que disfrutan las matemáticas por (3):

[tex]m = 418-15[/tex]

[tex]m = 403[/tex]
