Answer:

<h3>28feet</h3>

Step-by-step explanation:

Let the wallpaper be a rectangle

Area of a rectangle = Length * Width

A = LW

Perimeter P = 2L+2W

If the wallpaper is sold in rolls that are 2 feet wide, then the width is 2 feet, to get the length, substitute W = 2 and P = 60 into the formula for calculating the perimeter of a rectangle.

60 = 2L + 2(2)

60 = 2L + 4

2L = 60-4

2L = 56

L = 56/2

L = 28

<em>The minimum length that will be purchased to cover the wall is 28 feet</em>

STATISTICS The most familiar statistical measure is the arithmetic mean, or average. A second important statistical measure is t
NISA [10]

The absolute value equation for the scores within one standard deviation of the mean is:

|x - 20.9| = 5.3.

The minimum score that is within one standard deviation of the mean is of 15.6.

<h3>What is the absolute value function?</h3>

The absolute value function is defined by:

  • |x| = x, x >= 0.
  • |x| = x, x < 0.

It measures the distance of a point x to the origin of x = 0.

One standard deviation is of 5.3, while the mean is of 20.9, hence the absolute value equation for the scores within one standard deviation of the mean is:

|x - 20.9| = 5.3.

Which means that the minimum score is:

x - 20.9 = -5.3

x = 15.6.

A certain radioactive isotope decays at a rate of 2% per 100 years. if t represents time in years and y represents the amount of
gregori [183]
We rewrite the equation:
 y = y0 * e ^ (- 0.0002 * t)
 In this equation:
 I = represents the initial amount of the isotope
 We have then:
 89% of the isotope left:
 0.89 * y0 = y0 * e ^ (- 0.0002 * t)
 We clear the time:
 e ^ (- 0.0002 * t) = 0.89
 Ln (e ^ (- 0.0002 * t)) = Ln (0.89)
 -0.0002 * t = Ln (0.89)
 t = Ln (0.89) / (- 0.0002)
 t = 582.6690813
 round to the nearest year:
 t = 583 years
 Answer:
 
There will be 89% of the isotope left in about:
 
t = 583 years

The temperature in Anchorage, Alaska at 6 a.m. was 2°C. If the temperature drops 2 degrees each hour, what is the temperature in
Alchen [17]

Answer:

-14°C

Step-by-step explanation:

6 + 8 = 14

So in 24 hour time that would be 2pm

From 6am to 2pm is 8 hours

If the degrees is going down by 2 you would times the 8 by 2 because it is doubled

That = 16

Then you'll minus 16°C from the 2°C

2°C - 16°C

= -14°C
