Answer:
$72.80
Step-by-step explanation:
You would multiply 52 with .40 to get 20.8. This is how much the price increased by. Then you would add the 20.8 to your original price of 52 to get 72.80.
(Also you use .40 initially because percent means out of 100. So 40% is the same as .4)
A. 125 is the answer to your question
Answer: point b
Step-by-step explanation:
eatch mark on the line is 0.1, b is right behind the 8.6 mark in the middle making it 8.65
Normally, we could add exponents.
however, that only is possible when the bases are the same
recall what exponents mean
12³=12*12*12
so we cannot add exponents for 12³*11³ because that means 12*12*12*11*11*11
it would not equal 12⁶ or 11⁶
or you could refer to the rule

notice when x=x then we can add the bases
fun fact below
we can reverse a previous exponential rule like this
since

then

therefor

we can't add the exponents because the bases are not the same
If you are talking about the less than, greater than, and equal to circles. Then you need to simplify both fractions first. Number 2 is 1/5 O 2/10 You need to simplify 2/10. Both numbers are even so you can divide by 2 getting you 1/5. So Number 2 is 1/5=2/10. Hope this helped!
