You have 8,640 grams of a radioactive kind of cesium. If its half-life is 30 years, how much
Vikki [24]

The mass of cesium left afer 120 years if the original mass of cesium is 8640 with an half-life of 30 years,  is 540 grams.

<h3>What is half-life?</h3>

This can be defined as the time taken for half the amount of a radioactive substance to decay.

To calculate the amount of cesium left after 120 years, we use the formua below.

Formula:

  • R' = R/(2^{T/t})............. Equation 1

Where:

  • R = Original amount of Cesium
  • R' = New amount of cesium
  • T = Total time
  • t = Half-life

From the question,

Given:

  • R = 8640
  • T = 120 years
  • t = 30 years

Substitute these values into equation 1

  • R' = 8640/(2^{120/30})
  • R' = 8640/2^{4}
  • R' = 8640/16
  • R' = 540 grams.

Hence, The mass of cesium left afer 120 years is 540 grams.

Answer:

275 units^2

Step-by-step explanation:

The formula for the area of trapezoid is:

Area=((b1+b2)/2)*h

In the given trapezoid, as it can be seen

b1=16

h=11

The lower base will be calculated using all the lengths in the lower base

b2=9+16+9

b=34

Putting the values in formula

Area=((16+34)/2)*11

Area=(50/2)*11

Area=25*11

=275 units^2
