Answer:
I am pretty sure the answer would be $107.31. Sorry if I'm wrong.
Step-by-step explanation:
First you take the total of the 3 DVD's (45.99) and you divide that by 3 (number of DVD's) to get 15.33 which is called the unit price. Then, you take your unit price and multiply that by how many items you are going to buy.
45.99 / 3 = 15.33
15.33 x 7 = 107.31
Just plug in the numbers for the variables.
20+3(8)+17(2)=
Answer:
8022.
Step-by-step explanation:
Let x be the number of years after 2010.
We have been given a population of fish in a lake is 14000 in 2010. The population decreases 6% annually.
We can see that population of fish is the lake is decreasing exponentially as it is decreasing 6% annually.
Since we know that an exponential function is in form:
, where,
a = Initial value,
b = For decrease or decay b is in form (1-r) where r represents decay rate in decimal form.
Let us convert our given decay rate in decimal form.

Upon substituting our given values in exponential form of function we will get the population of fish in the lake after x years as:


Let us find x by subtracting 2010 from 2019.

Upon substituting x=9 in our function we will get,



Therefore, the population of fish in 2019 will be 8022.
Answer:850
Step-by-step explanation:
To find this 2% of x= 17
2/100×x=17
2x/100=17
2x=1700
x=850
Answer:The reason there is no commutative property for subtraction or division is because order matters when performing these operations.
