9514 1404 393

Answer:

  2205

Step-by-step explanation:

The area is multiplied by 1-4.75% = 0.9525 each year. After 7 years, the multiplication factor is 0.9525^7. Then the area is predicted to be ...

  3100 × 0.9525^7 ≈ 2205

Answer:

Step-by-step explanation:

This can be represented as exponential decreasing function.

   y = a(1 - r)t

       a = starting amount

       r = rate

       t = years

   y = 1600(1 - .0725)15

     = 1600(.9275)15

     = 1600(.32337673)

     = 517.40

In 15 years,  the forest will shrink in size to 517.40 km2

2. Find the surface area of a cylindrical can of tennis balls if the height of the can is 8
alina1380 [7]

Answer:

125.7 square inches

Step-by-step explanation:

The surface area of a cylinder is the sum of the areas of the two circles on each end and the area encircling "rectangle". Note that the length of this "rectangle" is the height of the can, while the width is the perimeter of the circle. The full equation is:

A=2 \pi r^2 +2 \pi r h\\A=2 \pi r(r+h)\\A=2 \pi (2)(2+8)\\A=40 \pi\\A=125.7

Malik collects rare stamps and has a total of 212 stamps. He has 34 more domestic stamps than foreign stamps. Let x represent th
Nana76 [90]
The equation that represents the total number of stamps malik collected is x + y = 212. The equation that represents the difference in the number of foreign and domestic stamps malik collected is: x - y = 34. This is the system of two equations. Malik has a total of 212 stamps: x + y = 212. He has 34 more domestic stamps (x) than foreign stamps (y): x = y + 34. If we rearrange it, we have x - y = 34. So, this is the system of two equations: x + y = 212 and x - y = 34.<span>

So it is an isosceles triangle that means that the bottom two angles are equal...
so 
40 = 5x 
divide both sides by 5 and you get 8

now the triangle angles add up to 180
we make an equation out of it...
(2y + 20 ) + ( 5(8)) + 40 = 180
2y + 20 + 40 + 40 = 180
combine like terms
2y + 100 = 180
so subtract 100 from both sides
2y = 80
divide by 2 to isolate the variable
y = 40

You are correct!!! :)
