A) [tex]-\frac{7}{4}[/tex]

Step-by-step explanation:

For this question, we can use the rise over run method, which means y over x.

So count how many it takes for the point on top to get to the bottom by x and y.

It takes 7 spaces down (y)  and 4 spaces to the right (x)

So do rise over run and we get

[tex]\frac{7}{4}[/tex]

Meaning that B and C are incorrect. Now what about A and D?

Well the slope is moving down, meaning that it is a negative slope, therefore there must be a negative sign for the slope.

[tex]-\frac{7}{4}[/tex]

A. is correct.

A force of 50N is applied to the end of a lever to lift a rock that is 350N. What is the MA of the lever? Is it actual or ideal?

Answers

Answer:

MA = 7, Actual

Step-by-step explanation:

Input force = 50N

Output force = 350N

MA = Output force / Input force

MA = 350 / 50 = 7

The difference between an ideal MA and an actual MA is that the former (ideal MA) uses distance while the latter (actual MA) uses force.

This is an Actual Mechanical Advantage

The MA of the lever will be "7" and it is actual.

According to the question,

Input force,

50 N

Output force,

350 N

As we know the formula,

→ [tex]MA = \frac{Out\ force}{Inp \ force}[/tex]

By substituting the values, we get

          [tex]= \frac{350}{50}[/tex]

          [tex]= 7[/tex]

Thus the above answer is correct as well as it is actual.

Work out the area of the rectangle using a calculator and
giving your answer as a mixed number.
2 2/7 cm
5 1/6 cm

Answers

Answer:

11 17/21 cm²

Step-by-step explanation:

Given

Length = 2 2/7cm

Width = 5 1/6cm

Area of the rectangle = Length * width

Area of the rectangle = 2 2/7 * 5 1/6

Area of the rectangle = 16/7 * 31/6

Area of the rectangle = (16*31)/(7*6)

Area of the rectangle  = 496/42

Area of the rectangle  = 11 34/42

Area of the rectangle  = 11 17/21

Hence the Area of the rectangle  is 11 17/21 cm²
