48 grams= 96% needed
x grams. = 4%
Set up a proportion
48/96 = x/4
96/24=4
48/24=2
x=2= grams in the granola
Add the value of 96% and the value of 4% to get the value of 100%
2+48=50
Final answer: 50 grams
The two equations are equal, so "The graphs of the equations are parallel lines." is false.
Answer:
Brainliest pls I never had brain before
Step-by-step explanation:
(126) times (1/2 to the x/11 power) = 15% times 126
(1/2) to the x/11 power = 0.15
Take the log of both sides :
(x/11) times log(1/2) = log(0.15)
Multiply both sides by 11 :
'x' times log(1/2) = 11 x log(0.15)
Divide both sides by " log(1/2) " :
x = 11 x log(0.15)/log(1/2) = <em><u>30.107 years</u></em> (rounded)
That's the time it takes for <em><u>any-size</u></em> sample of this substance
to decay to 15% of its original size.
