First let's find the cost of the dinner alone (without 8% sales tax) by solving the equation for x:

x + 0.08x = 32.40

1.08x = 32.40

x = 32.40/1.08

x = $30

Now calculate the 15% tip amount on the cost of the dinner alone:

(30)(0.15) = $4.50 (15% tip amount)

4) The simplest type of response is a direct one-to-one stimulus-response reaction. A change in the environment is the stimulus; the reaction of the organism to it is the response. In single-celled organisms, the response is the result of a property of the cell fluid called irritability.

5) During meiosis, the cells needed for sexual reproduction divide to produce new cells called gametes. Gametes contain half as many chromosomes as the other cells in the organism, and each gamete is genetically unique because the DNA of the parent cell is shuffled before the cell divides.

6)Producers can make their own food by capturing the sun's energy, but consumers and decomposes can't. Consumers need to eat other organisms to obtain energy. Decomposes are like the recycles of nature. They obtain energy for their own needs while returning simple molecules to the environment.

7)The birds are growing up into a larger bird.

8) Cells manage a wide range of functions in their tiny package growing, moving, housekeeping, and so on and most of those functions require energy. But how do cells get this energy in the first place? And how do they use it in the most efficient manner possible?

9)Aside from the fact that fish,and trees can be aged in similar ways (by counting annual growth rings), new research shows that all three also respond to climate change in similar ways.


10)No we will not be able to survive cause there is no food or water and it is only oxygen of course you will be able to breathe but not eat or drink.
