PLEASEE HELP.!! ILL GIVE BRAINLIEST.!! *EXTRA POINTS* DONT SKIP:((

Esta pregunta esta incompleta

Pregunta completa

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

These are complementary angles because from what this shows, they add up to 90 degrees. BTW Plz give brainliest, I need 5 to get to the next level.

Answer:

1\2.

Step-by-step explanation:

change in y over change in x. so 13 - 11 over 6 - 2. 2/4 --.> 1\2.

First you need to find the slope:  (y2 - y1)/(x2 -x1) = (-4 -(-4))/(0-2) = 0.  So the line is horizontal, which means the y coordinate is constant and equal to -4, so the equation of the line is y = -4.

Answer:

x=7

Answer:

Step-by-step explanation:

I believe the answer would be 1/4 of the sub. Because they asked about the whole sub. And it says he ate 1/4 of the amount of that half of the sub for snack. So out of the whole sandwich it would be 1/4!

If it’s not the answer your looking for you can take it off...

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

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!
