I=prt. I=600(.07)(2). I=42(2). I=84. Juanita will pay $84 interest :)
Answer:
$2.64
Step-by-step explanation:
9 coins are pennies (reply to my comment if you want to know how I got it)
19 coins are dimes (reply to my comment if you want to know how I got it)
9 (pennies) + 4 = 13 (nickels)
$1.90 (dimes) + $0.09 (pennies) + $0.65 (nickels) = $2.64
The side length (in feet) of the square that is Nina's garden is √141. The four sides of the square are the same length, so add to ...
... 4×√141 = 4×11.874 ≈ 47.497
Rounding to the nearest foot, we find Nina needs 47 feet of fencing.
_____
The answer digit in the tenths place is less than 5, so we round down to the next lower foot.
Note that if you actually multiply 11.874 by 4, you get 47.496. When you're working a problem like this, you always want to maintain full calculator precision until the end. The number we actually used in that multiplication was 11.874342087... (my calculator carries 32 digits). The number that gets rounded is 47.4973683482.... Enough digits are shown here to show how close the number is to being rounded to 48.
If you have your calculator set to show only two decimal digits, you will get the wrong answer. Your calculator will show you 47.50, which you would appropriately round to 48.
The total time taken for round trip will be: (f+g)(x) = 14x+11
Step-by-step explanation:
Given

In order to find the round-trip time, we have to add both functions to represent the time taken to travel east and the time taken to travel to west.

Hence,
The total time taken for round trip will be: (f+g)(x) = 14x+11

The first thing to do in this case is to draw the ordered pairs in the Cartesian plane and join the points.
We have then that the resulting figure is a rectangle.
We must find the perimeter of the rectangle that is given by:
P = 2L + 2W
Where,
L: long
W: width
Restoring the values:
P = 2 * (5) + 2 * (3)
P = 16
