Answer:

Mr. Mole is descending by 2.4 meters per minute

Step-by-step explanation:

Let

x ----> the time in minutes

y ---> the distance in meters

we know that

In this problem the rate of change or slope is the same that the speed

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

take two points from the table

(5,-18) and (8,-25.2)

substitute the values in the formula

m=\frac{-25.2+18}{8-5}

m=-2.4\ meters\ per\ minute ---> is negative because is descending

An angle measure of 55.45 is converted to DMS notation as
jek_recluse [69]

Converting angle measure of 55.45 to DMS notation we get 55 degrees 27 minutes 0 seconds

Step-by-step explanation:

We need to convert angle measure of 55.45 to DMS notation

DMS notation is Degree Minute and seconds

Solving:

We have 55.45, the value before decimal is considered as degrees and values after decimal can be minutes and seconds.

We can write it as 55 and 0.45

So, we have 55 degrees

To find minutes we will multiply 0.45 by 60

0.45*60 = 27 minutes

Since we have no decimal value in minutes so seconds will be 0

So, DMS will be 55 degrees 27 minutes 0 seconds

Hence converting angle measure of 55.45 to DMS notation we get 55 degrees 27 minutes 0 seconds

PAULA BROUGHT $39.63 WORTH OF GROCERIES SHE GAVE TELLER TWO TWENTY DOLLARS BILLS WHAT IS THE FEWEST COIN SHE CAN GET IN CHANGE
MakcuM [25]

Answer:

4 coins

Step-by-step explanation:

First, let's find out how much she gave the teller:

2($20)=$40

Now, let's find out how much change the teller owes her:

$40.00-$39.63=$0.37 or 37 cents

The largest coin (under 37 cents), is a quarter which is worth 25 cents...

37-25=12 cents

The largest coin (under 12 cents), is a dime which is worth 10 cents...

12-10=2

The largest coin (under 2 cents), is a penny which is worth 1 cent...

2-1=1

And one more penny...

1-1=0

Therefore the fewest amount of coins she can get in change are a quarter, a dime, and two pennies, which is 4 coins.
