Step-by-step explanation:

Levers are defined as the simple machine, which consists of a rod fixed at a pivot, load, and fulcrum. The levers are classified into first class, second, and third class.

A lever is a simple machine made of a rigid beam and a fulcrum. The effort (input force) and load (output force) are applied to either end of the beam. The fulcrum is the point on which the beam pivots. When an effort is applied to one end of the lever, a load is applied at the other end of the lever.

here, we have,

The difference between different types of levers are:

1. In the first-class levers, the fulcrum is present between the load and effort. The mechanical advantage can be greater, less, or equal to 1.

2. The second class levers, the load is present between the fulcrum and effort. The mechanical advantage is always greater than the 1.  

3. The third class levers, the effort is present between the fulcrum and load. The mechanical advantage is always less than 1.  

Thus, the correct answer is Option 1.

Answer:

Distance between home plate and second base = 127.3 ft (Approx)

Step-by-step explanation:

Given:

Base distance = 90 ft

Find:

Distance between home plate and second base

Computation:

Distance between home plate and second base = √90²+90²

Distance between home plate and second base = √8100 + 8100

Distance between home plate and second base = √16200

Distance between home plate and second base = 127.3 ft (Approx)

Answer:

4 4/10

Step-by-step explanation:

Well, 32/10 would by 3 2/10 when you divide it, I think. So 4 4/10 is greater.

Fractions may be equal or unequal.

[tex]\mathbf{4\frac{4}{10}}[/tex] is greater than [tex]\mathbf{\frac{32}{10}}[/tex]

The fractions are given as:

[tex]\mathbf{F_1 = 4\frac{4}{10}}[/tex]

[tex]\mathbf{F_2 = \frac{32}{10}}[/tex]

Express the fractions as improper fractions

[tex]\mathbf{F_1 = \frac{44}{10}}[/tex]

Both fractions have the same denominator.

So, the fraction with a greater numerator is greater.

By comparison: 44 is greater than 32

i.e. 44 > 32

Hence, [tex]\mathbf{4\frac{4}{10}}[/tex] is greater than [tex]\mathbf{\frac{32}{10}}[/tex]
