Answer: 61.5 square feet.

Explanation:

The surface area of all the figure is the sum of the areas of each plane:

1) Bottom: length * width = 7.5 ft * 1.5 ft = 11.25 ft^2

2) Front view: 7.5 ft * 1.5 ft + 2.5 ft * 1.5 ft = 11.25 ft^2 + 3.75 ft^2 = 15 ft^2

3) Back side = front = 15 ft^2

4) Top surfaces: 3 * 2.5 ft * 1.5ft = 11.25 ft^2

5) laterals = 4 * 1.5 ft * 1.5 ft = 9 ft^2

6) Total = sum = 11.25 ft^2 + 15 ft^2 + 15 ft^2 + 11.25 ft^2 + 9 ft^2 = 61.5 ft^2

Answer: 61.5 ft^2

The surface area is
A1=7.5*1.5*2=22.5 ft2 top and bottom view
A2=3*1.5*2=9 ft2 laterals view
A3=(7.5*1.5+2.5*1.5)*2=30 ft2  front and rear view

At=22.5+9+30=61.5 ft2
the answer is 61.5 ft2

Answer:

The area after 9 years will be 1,234 km^2

Step-by-step explanation:

In this question, we are tasked with calculating what the area of a certain forest that decreases at a certain percentage would be after some years.

To answer this question, we shall be using an exponential approximation.

Now, to use this exponential approximation, we shall be needing a supporting exponential mathematical equation.

This can be written as;

A = I(1-r)^t

where A is the new area we are looking for

I is the initial area which is 1700 according to the question

r is the rate of decrease which is 3.5% = 3.5/100 = 0.035

t is time which is 9 years according to the question

We plug these values and have the following;

A = 1700(1-0.035)^9

A = 1700(0.965)^9

A = 1,233.66

This is 1,234 km^2 to the nearest square kilometer

Los divisores de 100 son tambien divisores de 50 ?
sergiy2304 [10]

Answer:

La afirmación es falsa, no todos los divisores de 100 son divisores de 50, ya que solo se toman en cuenta sus divisores comunes, los cuales son todos los divisores de 50. Expresamos a 100 en sus factores primos: 100 = 2 · 2 · 5 · 5 = 2² · 5² Divisores de 100: {1, 2, 4, 5, 10, 20, 25, 50, 100}
