Tommy has a screw whose length is 4 cm and its thread length is 16 cm. What is the mechanical advantage of the screw?
Rus_ich [418]

Answer:

a screw is a simple machine that works as a modified inclined plane. You can think of the thread of the screw as an inclined plane wrapped around the shaft of the screw. The slope of the screw is the distance for one complete rotation while the height of the inclined plane is the distance between the threads, known as pitch. The relationship between the pitch and circumference of the screw gives the mechanical advantage.

True i think because going down a water-slide is really a translation, because you are changing from one place to another. SO i believe it would be true. Sorry if this isn't correct.

In order for the data in the table to represent a linear function with a rate of change of +5, what must be the value of m?
katen-ka-za [31]
<span>The table to represent a linear function with a rate of change of +5
</span>
so, m = 13 + 5 = 18

The correct answer is option 3 ⇒ <span>m = 18
</span>
========================================
another solution :
The table represents a linear function
the general equation of the linear function is ⇒ y = ax+b
where a is the slope and b is constant
By using the first and the third points from table to find the equation of the linear function
at x = 3  ⇒ y = 13   and   at x = 5 ⇒ y = 23
∴ 13 = 3a+b → (1)

23 = 5a+b → (2)
solve (1) and (2) to find a and b
So,  a = 5  and b = -2
∴ y = 5x - 2

After that by substitution with x = 4 int the equation of y
∴ y = 5*4-2 = 18

∴ m = 18

A shoe store costs 1800 dollars a month to operate. The average wholesale cost of each pair of shoes is 25 dollars, and the aver
likoan [24]

Answer: 45

Step-by-step explanation:

The store has to sell  

45

pairs of shoes.

Explanation:

The store has a base cost of  

$

1800

, the cost per pair of shoes is  

$

25

. Each pair of shoes is sold for  

$

65

, therefore the profit per pair of shoes is

$

65

−

$

25

=

$

40

The formula for calculating the amount that needs to be sold would look like this;

40

x

=

1800

To determine the value of  

x

, we take this formula;

x

=

1800

40

x

=

45

Therefore, the store needs to sell  

45

pairs of shoes to break even.
