Answer:

124%

Step-by-step explanation:

We can find the percent of the goal that she achieved while dividing the amount of time she exercised by the time she set as a goal. So, we have to figure out the value of 93/75. This is equivalent to 1.24. We can find 1.24 as a percentage by moving the decimal point over 2 (124) and then adding a percentage sign (124%). And that's the answer.

Hopefully that's helpful and all makes sense! :)

The difference between the two mass is 151950g

Data;

  • Mass a = 29.48kg
  • Mass b = 181,430g
<h3>Difference Between The Mass</h3>

To calculate the difference between the mass, we must do so in the same unit. i.e both mass a and mass b must be in the same unit.

<h3>Conversion of Mass from Kg to g</h3>

Let's convert mass a from kg to g

1kg = 1000g

Using this, we can find how many grammes are in 29.48kg

1kg = 1000g\\29.48kg = x\\x = 29.48 * 1000\\x = 29480g

Now we can find the difference between mass b and mass a

b - a = 181430 - 29480 = 151950

The difference between the two mass is 151950g
