The slope is -1

————————-

The formula for calculating the slope is change in y/change in x

1st (4, -6) and 2nd (-4, 2)

y2 - y1/x2 - x1

Add values from coordinates

2 - (-6)/(-4) - 4 = 8/-8 = -1

The slope is -1

A single little brown bat can eat up to 1,000 mosquitoes in a single hour. Express in scientific notation how many mosquitoes a
Nastasia [14]
Our final answer must represent "number of mosquitos."  This verifies that the correct calculation would be

1000 mosquitos              10.5 hours
-----------------------  x   --------------------
         1 hour                           1

Multiply this out.  Note that "hours" will cancel.

Whats your result?

Supposing that your result looked like   xxxxx times 10^0,

you'd convert this into scientific notation by moving the decimal place four units to the left (obtaining x.xxx) and then increasing the exponent of 10 from zero to four (obtaining 10^4).

Then your answer would have the form x.xxx times 10^4 (mosquitos)

The table shows the number of cell phone towers a
Olin [163]

Answer:

The correct option is;

B. Yes. The ratios of towers to customers (thousands) are all equivalent to a unit rate of 52 Towers/(Thousand customers)

Step-by-step explanation:

The given data can be presented as follows;

Cell Phone Towers

Customer (thousands)    {}   Towers

1) 5.25            {}                          273

2) 6.25            {}                         325

3) 7.25            {}                         377

4) 9.25            {}                         481

From the given data, we have the ratio Towers/Customer (thousands) given as follows;

For 1), we have;

273 Towers/(5.25 thousands customers) = 52 Towers/(Thousand customer)

For 2), we have;

325 Towers/(6.25 thousands customers) = 52 Towers/(Thousand customer)

For 3), we have;

377 Towers/(7.25 thousands customers) = 52 Towers/(Thousand customer)

For 4), we have;

481 Towers/(9.25 thousands customers) = 52 Towers/(Thousand customer)

Therefore, the ratios of towers to customers (thousands) all have the same equivalent unit rate of 52 Towers/(thousand customers).

What are the equivalent ratios shown in the table? Complete the statement.
Radda [10]
I will !

This is five-fold proportion
The first ratio gives solution namely
We will write general proportion 
a:b= c:d= e:f = g:h= i:j = k
According to this the first ratio gives coefficient k
When we divide 24/2 =12 our coefficient k=12

In the second ratio we will multiply 3 with 12 and get 36.
In the third ratio we will multiplu 5.5 with 12 and get 66.
In the fourth we will divide 108 with 12 and get 9.
In the fifth we will multiply 15 with 12 and get 180.

Finally the ratio is 24:2=36:3=66:5.5=108:9=180:15

Good luck!!!!
