Answer:
60
Step-by-step explanation:
AOC= AOB+ BOC
104= 7x+30 +9x+42
104= 16x+72
subtract both sides by 72
104-72=16x
32=16x
divide both sides by 16
x=2
BOC= 9(2) +42
BOC= 60
7/10 but in decimal form 0.7
<em>Answer:</em>
y = 100(6.3246^x)
<em>Explanation:</em>
Ao*k^x = A where Ao is the initial amt
k = constant factor
x = time in hrs
A = resulting amt
Write an equation from the 1st statement, x = 2 hrs, find k
100 * k^2 = 4000
k^2 = 4000%2F100
k^2 = 40
k = sqrt2840%29
k = 6.3246
The equation
:
y = 100(6.3246^x)

Step-by-step explanation:
To round $2.99 to the nearest cent we will look at the digit in the hundredths place which in this case it the 2nd 9 (2.99). If this number is 5 or higher we will round up and if it is less than 5 we will leave it. Since this is more than 5 we will round up to the nearest cent which would make it .00 which would make the number $2.99 rounded to the nearest cent $3.00.
Hope I helped ya!! xD
