First, find the tip amount. Convert the percent to a decimal. Move the % sign two places to the left and then make the % sign into a decimal point.

20% = 0.2

Then multiply 0.2 and 36 together.

0.2 * 36 = 7.2

Then add 7.2 to the cost of the dinner.

7.2 + 36 = 43.20

So, the answer is $43.20.

Answer:

See attached picture to view the graph

Step-by-step explanation:

Start by analyzing how this average idea works:

If only one member goes to the trip, it will cost him/her $1000+$200 = $1200.

If two members go to the trip, then they will share the cost as per the following: ($1000+ $200 + $200 = $1400) which they will be dividing into two people, thus costing each of them $700.

Notice that the general function that represents such average will be given by: $f(x) = \frac{1000+200x}{x}$

Plot such function in the two dimensional plane, and you will get the asymptotic behavior shown in the attached image.

The coordinates triangle ABC are A (0, 2), B (-2, 6), and C (4, 0). Find the slope of BC.

salantis [7]

In the given triangle, the slope of line BC is (C) -1.

<h3>What is the slope?</h3>

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.

A line's slope is how steeply it slopes from LEFT to RIGHT.

The slope of a line is determined by dividing its rise, or vertical change, by its run, or horizontal change.

No matter which two locations on the line you choose, the slope of a line is always constant (it never varies).

So, the slope of line BC:

Coordinates of BC are:

B: (-2, 6)

C: (4, 0)

Slope formula: m = y2-y1/x2-x1

Now, substitute the values and calculate as follows:

m = y2-y1/x2-x1

m = 0-6/4-(-2)

m = -6/6

m = -1

Therefore, in the given triangle, the slope of line BC is (C) -1.

Question:

Trent had $20.

He now has $7.50 left.

Let N = price per notebook.

N = (20.00 - 7.50)/5

N = $2.50

Each notebook sells for $2.50.

the function f(h)=2d+4.3 relates the h height of the water in a function on a calculator and use the graph to find the height of

Gemiola [76]

So, if "d" equals the diameter, we need to plug in 1.5 for "d". The equation now looks like: f(h) = 2(1.5) +4.3. Now if you multiply, it's: f(h) = 3 + 4.3, which then is: f(h) = 7.3. The height would be 7.3 in, when the diameter is 1.5 in. Hope this helps =). Have a great day!
