<span>At the city park there were 15 blue jays, 6 cardinals, and 9 mockingbirds.
6 mockingbirds is 2/3 of 9
so 2/3 of 6 is 4 cardinals
5 blue jays is 1/3 of 15
so 1/3 of 6 cardinals is 2 cardinals
There are 20 cardinals, how many mockingbirds.
the ratio is 2/3, so 20/30 is your answer
hope this helps</span>

Answer:
218
Step-by-step explanation:
ATQ,
22%of total books = 48
Let the total no. of books in library be x.
22/100x=48
x=4800/22
X=218(approximately)
To solve this we are going to use the half life equation
Where:
is the initial sample
is the time in years
is the half life of the substance
is the remainder quantity after
years
From the problem we know that:
Lets replace those values in our equation to find
:
We can conclude that after 1600 years of radioactive decay, the mass of the 100-gram sample will be
91.7 grams.
Hey there!!
To solve this, we will need to use the division property of exponents, which is :
mᵃ / mᵇ = mᵃ⁻ᵇ
In the question,
m = 6 ; a = 12 and b = 10
6¹² / 6¹⁰ = 6¹²⁻¹⁰ = 6² = 36
3 ( 36 ) = 108
Hope my answer helps!!
