No, because 2/5 is .4 and 4/12 is 1/3 or .333
So Jed is much faster than Alex in free throws.
Answer:
approximately 27 grams
Work Shown:
Half life formula
y = A*(0.5)^(x/H)
where,
A = starting amount = 30 grams
H = half life period = 90 years
x = number of years that pass by = 12
y = amount left over after x years
Let's plug the values for x, A and H into the formula to find y
y = A*(0.5)^(x/H)
y = 30*(0.5)^(12/90)
y = 27.3516746567466
y = 27 .... rounding to the nearest whole number
54
They have already played half the games, so you just multiply by two.
Given:
![\dfrac{1}{4}\text{ to }\dfrac{1}{2}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B4%7D%5Ctext%7B%20to%20%7D%5Cdfrac%7B1%7D%7B2%7D)
To find:
The percent of change, round to the nearest 10th of a percent.
Solution:
We have,
Initial value = ![\dfrac{1}{4}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B4%7D)
New value = ![\dfrac{1}{2}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B2%7D)
We know that, the percentage change is
![\%\text{ change}=\dfrac{\text{New value - Initial value}}{\text{Initial value}}\times 100](https://tex.z-dn.net/?f=%5C%25%5Ctext%7B%20change%7D%3D%5Cdfrac%7B%5Ctext%7BNew%20value%20-%20Initial%20value%7D%7D%7B%5Ctext%7BInitial%20value%7D%7D%5Ctimes%20100)
Putting the given values, we get
![\%\text{ change}=\dfrac{\dfrac{1}{2}-\dfrac{1}{4}}{\dfrac{1}{4}}\times 100](https://tex.z-dn.net/?f=%5C%25%5Ctext%7B%20change%7D%3D%5Cdfrac%7B%5Cdfrac%7B1%7D%7B2%7D-%5Cdfrac%7B1%7D%7B4%7D%7D%7B%5Cdfrac%7B1%7D%7B4%7D%7D%5Ctimes%20100)
![\%\text{ change}=\dfrac{\dfrac{2-1}{4}}{\dfrac{1}{4}}\times 100](https://tex.z-dn.net/?f=%5C%25%5Ctext%7B%20change%7D%3D%5Cdfrac%7B%5Cdfrac%7B2-1%7D%7B4%7D%7D%7B%5Cdfrac%7B1%7D%7B4%7D%7D%5Ctimes%20100)
![\%\text{ change}=\dfrac{\dfrac{1}{4}}{\dfrac{1}{4}}\times 100](https://tex.z-dn.net/?f=%5C%25%5Ctext%7B%20change%7D%3D%5Cdfrac%7B%5Cdfrac%7B1%7D%7B4%7D%7D%7B%5Cdfrac%7B1%7D%7B4%7D%7D%5Ctimes%20100)
![\%\text{ change}=1\times 100](https://tex.z-dn.net/?f=%5C%25%5Ctext%7B%20change%7D%3D1%5Ctimes%20100)
![\%\text{ change}=100\%](https://tex.z-dn.net/?f=%5C%25%5Ctext%7B%20change%7D%3D100%5C%25)
Here, the % change is positive, it represents the percent increase.
Therefore, the percent of change is 100% of increase.
Answer:
3.75
Step-by-step explanation:
Divide 2.5 by 2 to find out what 1/3 would be, then multiply that by 3 to get your answer - 3.75 pounds of chicken are called for
