Answer:

$450

Step-by-step explanation:

The area of the square is 40,000 square feet so the square's side length is 20 (√40,000).

The company charges $2.50 per foot, and the perimeter is 80 (20*4), so the  cost is $400 ($2.50 * 8).

Add on the $50 installation fee and the total cost is $450 ($400 + $50).

diego is collecting pennies and estimated that he has 120 pennies. he counted them and has 80 pennies. what is diego's percentag
Bezzdna [24]

Answer:

50%

Step-by-step explanation:

The percent error is equal to the absolute value, difference of the measured value or your experimental value minus the actual value divided by the actual value times 100%;

Here we have;

Measured Valued = 120 pennies

Actual Value = 80 pennies

% error = \frac{|Measured - Actual|}{Actual} * 100

% error = \frac{|120 - 80|}{80} * 100

% error = \frac{|40|}{80} * 100

% error = \frac{40}{80} * 100

% error = 50%

So, 50% is the percent error for Diego

GaryK [48]

Answer:

Step-by-step explanation:

Given the following :

Laps - - - - - - - - 5 - - - 6 - - - 7 - - - 8 - - - 9

Total time - - - 25 - - 28 - - 29 - - 30 - - 32

Using online graphing tool:

The y - axis named dependent variable represents the total time taken.

The x-axis, represents the number of laps.

The equation of the trend line attached to the plot is in the form :

y = mx + c

y = 1.6x + 17.6

Where y = total time taken

x = number of laps

m = 1.6 = gradient of the line (change in y / change in x)

C = 17.6 = intercept (whee the trndline intersects the y-axis).
