Answer:
$5.47
Step-by-step explanation:
Given data:
Annie has 4 dollar , 11 dimes, 4 pennies.
Tommy has 3 dimes, 3 pennies.
To add the money, let us first convert dime and penny into dollar.
1 dollar = $1
11 dime = $1.1
4 penny = $0.04
3 dime = $0.3
3 penny = $ 0.03
Total money = Annie’s money + Tommy’s money
= $4 + $1.1 + $ 0.04 + $0.3 + $0.03
= $5.47
So, they have $5.47 in all.
Use desmos graphing calculator
-9 in power means that the value is in fractional and the 10 base is multipied 9 times and put it on denominator.
8.6 = 86 x 10^-1
Let's multiply :
86 x 10^-1 x 10^-9
= 86 x 10^-10
= 86/10000000000
=0,0000000086
Note : if you don't know about how 10^-1 x 10^-9 returns 10^-10, it's because of exponential rules. If the base are same wuth each other, then just do the addition operation in the exponent like this :
10^(-1+(-9))
= 10^(-1-9)
=10^-10
Hope it helps :)
The answer is a I hope this helped you out
