Answer:
150 pennies were lost altogether
Step-by-step explanation:
Let the initial number of pennies owned by Dante be x pennies
Let the initial number of pennies owned by Mia be y pennies
Mathematically ;
x + y = 350 •••••••(i)
So after losing half, dante will have x/2 pennies left.
Mia lost 1/3 so she will have 2/3y left
So after all the losses, they both had equal amount of pennies
This means that;
x/2 = 2y/3
Cross multiply;
3x = 4y •••••••(ii)
Let’s solve both equations simultaneously;
From i , x = 350-y
Substitute this into equation ii
3(350-y) = 4y
1050-3y = 4y
7y = 1050
y = 1050/7
y = 150
since x = 350-y
x = 350-150 = 200
Now Dante loss x/2 = 200/2 = 100
Mia lost 1/3y = 1/3 * 150 = 50
Total pennies lost = 100 + 50 = 150
Answer:
Mean = 28.33
Step-by-step explanation:
Comment
You need two inputs. The first is the sum of the numbers and the second is the number of entries in the data.
Givens
Sum = 3 + 32 + 36 + 30 + 33 + 36
Number of entries = 6
Solution
Sum = 170
Mean = sum / number of enteries
Mean = 170 / 6
Mean = 28.33
The result of the expression in exponential form is 9^-4
