Answer:

6.

Step-by-step explanation:

A simple machine can be defined as a type of machine with no moving parts but can be used to perform work.

Basically, a simple machine allows for the transformation of energy into work. The six simple machines are; lever, wedge, inclined plane, screw, wheel and axle, and pulley.

A pulley is typically made up of a wheel and rope which allows force to be multiplied such as in a drawing well.

In order to construct a compound pulley with an ideal mechanical advantage of 6 you would arrange several fixed and movable pulleys so that a total of 6 rope segments were pulling up on the load.

Hence, you need 6 pulley wheels and 6 rope segments to construct a compound pulley with an ideal mechanical advantage of 6.

To find the ideal mechanical advantage;

Mathematically, IMA is given by the formula;

[tex] IMA = \frac {distance \; over \; which \; the \; effort \; is \; applied}{distance \; the \; load \; travels} [/tex]

NB: The ideal mechanical advantage has no units.

Answer:

(Square, Right Triangle)

18 meters²

Step-by-step explanation:

You can divide the shape into a square and right triangle, see the attachment :)

The area of the square is the length times the width. So,

3 · 3 = 9

The area of the square is 9 m².

The triangle's area is the base times the height divided by 2. So,

6 · 3 = 18

18 / 2 = 9

The triangle has an area of 9 m².

Add these together.

9 + 9 = 18

The area is 18 meters².

Answer:

175 pi ^3

Step-by-step explanation:

The volume of the cylinder is 175π cubic units or 175π units³ if the radius of the base r is 5 units and the height of the cylinder h is 7 units option (A) 175π units³ is correct.

In geometry, it is defined as the three-dimensional shape having two circular shapes at a distance called the height of the cylinder.

We know the volume of the cylinder is given by:

[tex]\rm V = \pi r^2 h[/tex]

Volume can be defined as a three-dimensional space enclosed by an object or thing.

As we know,

We can find the volume of the cylinder by using the given formula:

[tex]\rm V = \pi r^2 h[/tex]

The radius of the base r = 5 units

The height of the cylinder h = 7 units

[tex]\rm V = \pi (5)^2 (7)[/tex]

V = 25x7π

V = 175π cubic units

Or

V = 175π units³

Thus, the volume of the cylinder is 175π cubic units or 175π units³ if the radius of the base r is 5 units and the height of the cylinder h is 7 units option (A) 175π units³ is correct.

Answer:

Step-by-step explanation:

LA = pi*r*l = 3.14*8.5*12.4 = 331

SA = LA + pi*r^2 = 331 + 3.14*8.5^2 = 558

V = 1/3*pi*r^2*h = 1/3*3.14*(8.5^2)*sqrt(12.4^2-8.5^2) = 683

Answer:

331

558

683

Step-by-step explanation:

LA = 3.14x8.5x12.4 = 330.9 = 331

SA = 331+3.14x8.5^2 = 557.9 = 558

V = 1/3x3.14x(8.5^2)x(12.4^2-8.5^2)^0.5 = 682.7 = 683

Answer:

60%

Step-by-step explanation:

Number of people ages 26 - 35 prefer Ad A = 12

Number of people ages 26 - 35 prefer Ad B = 8

Total people ages 26 - 35 = 12 + 8

= 20

Percent of people ages 26 - 35 prefer Ad A = Number of people ages 26 - 35 prefer Ad A / Total people ages 26 - 35 × 100

= 12/20 × 100

= 0.6 × 100

= 60%

Percent of people ages 26 - 35 prefer Ad A = 60%

Answer:

1. s=7

2 s = 8

Step-by-step explanation:

s + 12 =19 you subtract 12 from 19 and you get 7 so you rewrite it like this s = 7 then divide s by 7 and get s = 7

s - 6=2 add 6 to both sides so 6+2 equals 8

s=8

Answer: The best player is expected to make  

21 more free​ throw(s).

Step-by-step explanation:

1) Make a proportion

2) Find the unknowns

3) Subtract the greater number from the smaller one

4) That's it.

Answer:

He is expected to make 21 more free throws

Step-by-step explanation:

we know that the probability for the best player is 8/10 or 80%

the probability for the second best is 13/20. This is equivalent to 65%

They each attempt 140 free throws.

We need to figure out what 80% of 140 is. To do this, we need to multiply 140 by 0.80. 140 * 0.80 = 112

We do the same for the second best

140 * 0.65 = 91

112 - 91 = 21.

Answer:

look at the picture i sent......

As altitude within the troposphere increases, the amount of water vapor in the atmosphere generally decreases.

The bottom of the troposphere, close to ground level, has the warmest air. As one ascends into the troposphere, the air becomes cooler. Because of this, tall mountains' peaks might still have snow on them in the summer. Along with decreasing with altitude, so do air pressure and air density.

As, The troposphere's temperature and water vapour content drop sharply with altitude.

This is because it absorbs solar energy and thermal radiation from the planet's surface, water vapour plays a significant role in controlling the temperature of the atmosphere.

99% of the water vapour in the atmosphere is found in the troposphere.

Thus, the water vapor decreases.
