Mai has a rectangular poster. The poster is 1.6 meters long and 1.2 meters wide.
dangina [55]

Answer:

19,200 cm^2.

Step-by-step explanation:

The area = 1.2 * 1.6 = 1.92 m^2.

There are 100 cm to 1 meter,  so 1 square meter = 100^2 = 10,000 cm^2.

Therefore 1.92 m^2 = 10,000 * 1.92 =  19,200 cm^2.

A hospital uses cobalt-60 in its radiotherapy treatments for cancer patients. Cobalt-60 has a half-life of 7
NeTakaya

Answer:

We have 197 g of Co-60 after 18 months.

Step-by-step explanation:

We can use the decay equation.

M_{f}=M_{i}e^{-\lambda t}

Where:

  • M(f) and M(i) are the final and initial mass respectively
  • λ is the decay constant (ln(2)/t(1/2))
  • t(1/2) is the half-life of Co
  • t is the time at the final amount of m

M_{f}=228e^{-\frac{ln(2)}{7} 1.5}    

M_{f}=197\: g    

<u>Therefore, we have 197 g of Co-60 after 18 months.</u>

I hope it helps you!
