Answer:
In which t is measured in decades.
Step-by-step explanation:
A linear function f(t) has the following format:
We are given two points of the function, so we can solve a system of equations to find the values for a and b.
61% of all adults in 1971 (t = 0)
This means that
So
51% in 2011 (t = 4)
This means that
So
So the linear function is:
In which t is measured in decades.
2×+7=27
2×-7=27-7
2× =20
2/× =20/2
× = 10
2(10)+7=27
3×+1=28
3×-1=28-1=27
3× =27
3/× =27/3
× =9
3(9)+1=28
27 does not equal 28
so no
Step-by-step explanation:
13=blue blankets 7=red blankets
First, we need to know how many blankets there are in total.
13+7=20
Now, we don't need the seven anymore. Our ratio is blue blankets to total blankets.
13/20
Now, we need to know how many blue blankets there are in percentage.
13/20 = x/100
Next step: 13 times 100 is divided by 20
x= 13(100)÷20
x=1300÷20
x= 65
Therefore there are 65% of blue blankets.
I think that the correct answer is B
Hope that helps.
