Answer:

O is a whole number.

Step-by-step explanation:

Answer:

0 is not a natural number, it is a whole number.

Step-by-step explanation:

Negative numbers, fractions, and decimals are neither natural numbers nor whole numbers. N is closed, associative, and commutative under both addition and multiplication (but not under subtraction and division).

Answer:

$83.60

Step-by-step explanation:

to find the answer you need to know the price of one pint (unit rate) so we divide 12.54 by 6.

12.54 ÷ 6 = 2.09

then we multiply that by 40

2.09 x 40 = 83.60

Answer:

A = (-6, 4)

B = (2,2)

C =  (-2, 2)

Step-by-step explanation:

If a coordinate (x, y) is dilated by a factor of k, the resulting coordinate will be expressed as (kx, ky). Note that each coordinate is multiplied by the scale factor  Given the coordinates (-3,2),(1,1)(-1,-1), if they are dilated by a factor of 2, the resulting coordinate will be;

A = (2(-3), 2(2)) = (-6, 4)

B = (2(1),2(1)) =(2,2)

C = (2(-1), 2(-1)) = (-2, 2)

Answer:

perimeter of figure A is 40 cm

..

breadth of figure B is 3.33. {ie,3 whole 4 by 12}

Answer:

subtract the 3x from one side and put in the other

4y = -3x -2

then divide both sides by 4

y= -3/4x -1/2

so the slope is-3/4

Answer: Use Newton's first rule of motion to make your workout more difficult.

This rule says that until acted upon by an external force, a body continues in motion.

By altering the ground on which you exercise, you may reduce the influence of inertia on your exercises, as inertia maintains you going forward.

Workout on materials that slow it down your upward motion, requiring you to expend more energy to keep going ahead.

Run on sand rather than tarmac, or do aerobic exercises on rubber mats rather than wood flooring.

Queremos encontrar y resolver un sistema de ecuaciones para encontrar el número de novillos comprados y el valor de cada uno.

Encontramos que las soluciones son:

La información que tenemos es:

El comerciante compro un dado número de novillos, digamos N.

El precio total fue de 1,440,000 colones.

Entonces si el precio de cada novillo es P, tenemos que:

N*P = 1,440,000

Sabemos que vendio 20 a 22,000 colones cada uno, es decir, obtuvo:

20*22,000 colones = 440,000 colones.

Es decir, de momento se tiene una perdida de:

1,440,000 - 440,000 = 1,000,000 colones.

Sí quiere obtener una ganancia de 200,000 colones, debe vender los (N - 20) novillos restantes a 2,000 colones más que P.

De esto planteamos la ecuación:

(N - 20)*(P + 2,000)= 1,000,000 colones + 200,000 colones = 1,200,000 colones.

Entonces tenemos el sistema de ecuaciones:

N*P = 1,440,000

(N - 20)*(P + 2,000) = 1,200,000

Para resolver esto comenzamos por aislar una de las variables en la primera ecuación, aislaremos N

N = (1,440,000)/P

Ahora reemplazamos esto en la otra ecuación:

(N - 20)*(P + 2,000) = 1,200,000

( (1,440,000)/P - 20)*(P + 2,000) = 1,200,000

Ahora debemos resolver esto para P.

1,440,000 - 20*P - 20*2,000 + 2,000*(1,440,000)/P = 1,200,000

- 20*P + 2,000*(1,440,000)/P = -180,000

Multiplicando ambos lados por P, obtenemos:

-20*P^2 + 2,880,000,000 = -180,000*P

Reescribimos esto como una ecuación cuadratica:

-20*P^2 +   2,880,000,000 + 180,000*P = 0

Y podemos resolver esto usando la formula de Bhaskara.

[tex]P = \frac{-180,000 \pm \sqrt{(180,000)^2 - 4*(-20)*(2,880,000,000)} }{2*-20} \\\\P = \frac{-180,000 \pm 512,640.22471 }{-40}[/tex]

Solo nos interesa la solución positiva, que es:

[tex]P = = \frac{-180,000 - 512,640.22471 }{-40} = 12,820.5[/tex]

Es decir, cada novillo le costó 12,820.5 colones.

y sabemos que:

N = 1,440,000/P = 1,440,000/12,820.5 = 112.3

Redondeamos al proximo numero entero, que es 112, donde ese 0.3 debe venir de algun error de redondeo (o más probablemente a un problema mal planteado).

Answer:

Your car is faster of course

Step-by-step explanation:

100 km would be 100000 meters. Then you would need to know that if Usain bolt ran 100 meters every 9.54 sec then in 100000 meters he would have ran 9540 seconds which is also known has 159 minutes, which is more than 1 hour so your car is faster.

Answer:

61

Step-by-step explanation:

So basically you separate the numbers like 1 1 1 1 0 1, and time 2 while having the number of numbers as the exponent decreasing. Like this, 1x2^5+1x2^4+1x2^3+1x2^2+0x2^1+1x2^0. Then figure it out and it would be 32+16+8+4+0+1=61. If don't understand, look at the picture below

Base 10 blocks are used to perform arithmetic operations.

To model the product of 3 and 0.51, Evan needs 3 copies of 5 tenths and 1 hundredths.

The expression can be represented as:

[tex]\mathbf{3 \times 0.51}[/tex]

Express 0.51 as 0.5 + 0.01

[tex]\mathbf{3 \times 0.51 = 3 \times (0.5 + 0.01)}[/tex]

Hence, Evan needs 3 copies of 5 tenths and 1 hundredths.

Step-by-step explanation:

I don't understand this at all I have no been getting this in school

6.4/3.5, OR about 1.83

First job is to isolate the y.

3.5y=6.4x+7

Now divide both sides by 3.5 to get the equation into y=mx+b form.

That leaves a rounded equation of y=1.83x+2

In y=mx+b, the m is the slope. This means the slope of this line is 1.83, or 6.4/3.5

Answer:

Maximum height 8 feet; horizontal distance 11 feet

Step-by-step explanation:

got it right

The maximum height and horizontal distance is required.

Maximum height 8 feet; horizontal distance 16 feet

The given path is [tex](x-3)^2=-8(y-8)[/tex]

If the skateboarder jumps at x = 0 she will land at y = 0. However there will be at horizontal displacement.

[tex](x-3)^2=-8(0-8)\\\Rightarrow (x-3)^2=8^2\\\Rightarrow x-3=\pm 8\\\Rightarrow x-3=8\\\Rightarrow x=11[/tex]

or

[tex]x-3=-8\\\Rightarrow x=-5[/tex]

The distance between -5 and 11 is [tex]11-(-5)=16[/tex]

Middle point would be [tex]\dfrac{16}{2}=8[/tex] from [tex]-5[/tex].

[tex]-5+8=3[/tex]

So, [tex]x=3[/tex]

The maximum height will be

[tex](3-3)^2=-8(y-8)\\\Rightarrow y-8=0\\\Rightarrow y=8[/tex]

The maximum height is 8 feet and the horizontal distance is 16 feet.

Answer:

slope = 3

y-intercept = -4

Step-by-step explanation:

In order to find the slope and the y-intercept, transform the given equation into its slope-intercept form, y = mx + b:

Add 9x to both sides:

-9x + 9x + 3y = 9x - 12

3y = 9x - 12

Divide both sides by 3:

[tex]\frac{3y}{3} = \frac{9x - 12}{3}[/tex]

y = 3x - 4    This is the slope-intercept form where the slope, m = 3, and the y-intercept, b = -4.

To graph the line, start at the y-intercept (0, -4). Then, use your slope, m = 3 (rise 3 units, run 1 unit).  Attached is a screenshot of the graphed line, using the rise/run technique. I also plotted extra points.
