400÷4/7=700
you want divide the totals amount of lemonade among pitchers that only hold 4/7 of the lemonade. if the container held 1 qt, you would divide the total by 1
0.56 5 (per 1) is the amount each friend gets
Answer:
2 seventh graders
Step-by-step explanation:
8:16 simplified=1:2
therefore for every 1 sixth-grader there is 2 seventh graders
The exponential function is defined as y = a(1+r)^x, where "a" represents the original account and "r" the rate of growth or decay.
Then we have the following:
1) 22% grow
y = a( 1 + 22%/100 )^x = a(1.22)^x
So the solution is: 124(1.22)^x
2) 12% decay
y = a( 1 - 12%/100 )^x = a(0.88)^x
So the solution is: y = f(x) = 44(0.88)^x
3) 20% decay
y = a( 1 - 20%/100 )^x = a(0.8)^x
So the solution is: f(x) = 22(0.8)
4) 12% Groth
y = a( 1 + 12%/100 )^x = a(1.12)^x
So the solution is: f(x) = 42(1.12)^x
