Answer:

B. The student multiplied 380 by \frac{19}{20}.

Step-by-step explanation:

In the equation -\frac{3}{4}y - \frac{1}{5}y = 380, we can further evaluate the equation into:

-\frac{19}{20}y = 380

To find y, we need to multiply 380 by the inverse of the fraction on the other side, which is -\frac{20}{19}. However, the students multiplied 380 by \frac{19}{20} to get 361. Thus, this was the mistake.

Suppose you are asked to find the area of a rectangle that is 2.1-cm wide by 5.6-cm long. Your calculator answer would be 11.76
yKpoI14uk [10]

Answer:

12 cm²

Step-by-step explanation:

Length of rectangle = 5.6 cm

Width of rectangle = 2.1 cm

Area of rectangle = Length of rectangle×Width of rectangle

⇒Area of rectangle = 5.6×2.1

⇒Area of rectangle = 11.76 cm²

11.76 has 4 significant figures in order to write this term in 2 significant terms we round of the term

The last digit in the decimal place is 6. Now, 6≥5 so we round the next digit to 8 we get

11.8

Now the last digit in the decimal place is 8. Now, 8≥5 so we round the next digit to 2 we get

12

∴ Hence the area of the rectangle when rounded to 2 significant figures is 12 cm²
