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.

Charlie gathers apples, pears, and plums. The numbers of apples and plums are 10-partners. There are the same number of apples a

aalyn [17]

Answer:

The total number of pieces of fruit that Charlie can gather ranges from 11 to 19.

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Numbers of apples and plums are 10-partners, it means that the sum of apples and plums is 10.

Number of apples and pears are the same.

2. How many pieces of fruit can Charlie gather?

Apples = a

Plums = p

Pears = s

a + p = 10

Possible values of a and p:

1 + 9, 2 + 8, 3 + 7, 4 + 6, 5 + 5, 6 + 4, 7 + 3, 8 + 2, 9 + 1

Possible values of s:

1, 2, 3, 4, 5, 6, 7, 8, or 9

Therefore, the total number of pieces of fruit that Charlie can gather ranges from 11 to 19.

Answer:

clockwise from left, the missing side lengths are 8 m, 13 m, 8 m

Step-by-step explanation:

The perimeter of the figure is the sum of the lengths of its sides. Sides with the same hash mark have the same length, so the perimeter (in meters) is ...

38 = (3x+1) +(2x) +(9) +(2x)

38 = 7x +10

28 = 7x . . . . . . subtract 10

4 = x . . . . . . . . divide by 7

Then the short sides are ...

2x = 2·4 = 8 . . . meters

and the long side is ...

3x+1 = 3·4 +1 = 13 . . . meters
