Calcula el número de vueltas por minuto que hace la polea pequeña mientras que la grande hace 40 vueltas. Sabiendo que cada polea gira de manera que el radio y el número de vueltas son inversamente proporcionales.

El radio de la polea pequeña = 3 cm.

El radio de la polea grande = 9 cm

Answer:

120 vueltas por minuto

Step-by-step explanation:

El radio y el número de vueltas son inversamente proporcionales.

Por lo tanto

R = Radio

T = El número de vueltas por minuto

R ∝ 1 / T

R = k / T

Donde k es constante de proporcionalidad

Polea grande

R = 9 cm

T = 40 vueltas

9 = k / 40

k = 9 × 40

k = 360

Debemos encontrar el número de vueltas para la polea pequeña, por lo tanto,

R = k / T

k = 360, R = 3 cm

3 = 360 / T

3 × T = 360

T = 360/3

T = 120 vueltas

El número de vueltas de la polea pequeña = 120 vueltas por minuto

Answer:

Average growth= 11.20 feet

Step-by-step explanation:

First, we need to calculate the total growth during those 312 years:

Total growth= 3,512 - 18

Total growth= 3,494 feet

Now, the average growth:

Average growth= total growth / number of years

Average growth= 3,494 / 312

Average growth= 11.20 feet

Answer:

-5

Step-by-step explanation:

-2x+7>17

-2x>17-7

-2x>10

Divide both sides by -2

-2x<10

-2 -2

x<-5

Note:when dividing with a negative the signs changes

Answer:

Step-by-step explanation:

- 2x + 7 > 17

- 2x > 17 - 7

- 2x > 10

x < 10 ÷ ( - 2 )

x < - 5

x ∈ ( - ∞ , - 5 )

Answer:

$450. The amount Antonio bought the tv for was $450.

Step-by-step explanation:

If all the tv's are 30%, multiple 30 by the price of the tv he wants, giving you 45000. Then, divide by 100 because a percent is out of a hundred, giving you $450

Formula:

(30x1500)/100

Answer:

2, - 3, 18

Step-by-step explanation:

1). [tex]\sqrt[3]{1-x}[/tex] = - 1

( [tex]\sqrt[3]{1-x}[/tex] )³ = ( - 1)³

1 - x = - 1 ⇒ x = 2

2). [tex]\sqrt{x^2 +7}[/tex] = 4

( [tex]\sqrt{x^2 +7}[/tex] )² = 4²

x² + 7 = 16 ⇒ x = ± 3 ; x = - 3

3). [tex](x-2)^{\frac{1}{4} }[/tex] = 2

[tex][(x-2)^{\frac{1}{4} }] ^{4}[/tex] = [tex]2^{4}[/tex]

x - 2 = 16

x = 18

Simplify the expression.

Answer:

Elevator 2

Step-by-step explanation:

Well let's make this simply by focusing on elevator number 1

it is on the 6th floor so we represent that as

6

Now it goes up 7/4 which is also the same as 1 3/4

the equation looks like this:

6+1 3/4

Add them together:

7 3/4

Now it goes down 10 meaning it is -10 add that to the equation:

7 3/4 - 10

Which is -2 1/4

Elevator number 1 is at floor number -2 1/4

Now for Elevator number 2

It is on the 20th floor which will make the equation looks like this:

20

Now it goes down five floors three times which can be represented like this:

20-5(3)

Simplify (Multiplication goes first according to the Order of Operations)

20-15= 5

Now it is 5 but it goes up 12 floors so the equation looks like this:

5+12

Simplify:

17

Now you could tell that elevator 2 ends up on a higher floor

Hope this helps!

Answer:

There the coordinates of the point are:

(x, y) = (-2.5, 1.5)

Therefore, option 'b' is true.

Step-by-step explanation:

From the coordinate plane, it is clear that the point is located in the 2nd quadrant.

We know that the second quadrant has negative x values and positive y values.

2nd quadrant → (-, +)

The point is clearly located at the location at x=-2.5 and y=1.5

There the coordinates of the point are:

(x, y) = (-2.5, 1.5)

Therefore, option 'b' is true.
