No one will answer this probably wasting my points XD) Spunky the terrier is chasing a chicken. Spunky runs at a rate of r feet

per second while the chicken runs at a rate of v feet per second. The chicken is originally 15 feet from Spunky and he catches up to it in 20 seconds. Which equation represents this information?
a. 20r−15=20v20r-15=20v
b. =20r+20v15=20r+20v
c. 20r=20v−1520r=20v-15
d. 20−15r=20+v

Answer:

An arithmetic sequence has a constant difference between each term.

For example: 2,4,6,8,10,12,…

We can see clearly that all the terms differ by +2.

We call this the common difference, d.

A geometric sequence has a constant ratio (multiplier) between each term.

An example is: 2,4,8,16,32,…

So to find the next term in the sequence we would multiply the previous term by 2.

This is called the common ratio, r.

These sequences are closely related as they both have the same first term, but I hope you can see how different they become if they have a common difference or a common ratio.

We can create a decreasing arithmetic sequence by choosing a negative common difference.

Similarly, a decreasing geometric sequence would have a common ratio of less than 1.

A restaurant wishes to have at least one server for every 12 tables. Each of the tables in the restaurant seats four guests. If
Fiesta28 [93]
X = number of servers
y = number of guests

\text {number of guest per table = } 4<span>

</span>\text {number of tables = } \dfrac{y}{4}
<span>
</span>\text {number of servers needed = } \dfrac{y}{4} \div 12<span>

</span>\text {number of servers needed = } \dfrac{y}{4} \times  \dfrac{1}{12}

\text {number of servers needed = } \dfrac{y}{48}

There must be at least 1 server for every 12 tables:
x \geq \dfrac{y}{48}

Polygon ABCD has the following vertices: A(−3, 3), B(5, 5), C(5, −4), and D(−3, −4) Calculate the area of the polygon.
aniked [119]

To solve this problem you must apply the proccedure shown below:

1. When you plot the given points, you obtain a trapezoid, therefore, you must apply the formula for calculate the area of a trapezoid, which is:

A=\frac{(B+b)h}{2}

Where B is the larger base, b is the smaller base and h is the height.

2. The dimensions are:

B=9units\\ b=7units\\ h=8units

3. Substitute values:

\\A=\frac{(9 units+7units)(8units)}{2}  A=64 units^{2}

The answer is: 64 units^{2}
