Step-by-step explanation:

Step 1:

x - > number of Avocado

y -> number of melon

Step 2:

x ≤ 3y

x + y ≥ 20

Step 3:

x + y≥ 20

y ≥ -x + 20

Step 4:

( 1 , 20)

x ≤ 3y ; y≥ -x + 20

1 ≤ 3*20 ; 20 ≥ -1 + 20

1 ≤ 60 ; 20 ≥ 19

At the beginning of an environmental study, a forest covered an area of 1500 km2 . Since then, this area has decreased by 9.8% e

fredd [130]

Answer:

$A(t)=(0.902)^t \cdot 1500$ $[km^2]$

Step-by-step explanation:

In this problem, the initial area of the forest at time t = 0 is

$A_0 = 1500 km^2$

After every year, the area of the forest decreases by 9.8%: this means that the area of the forest every year is (100%-9.8%=90.2%) of the area of the previous year.

So for instance, after 1 year, the area is

$A_1 = A_0 \cdot \frac{90.2}{100}=0.902 A_0$

After 2 years,

$A_2=0.902 A_1 = 0.902(0.902A_0)=(0.902)^2 A_0$

And so on. So, after t years, the area of the forest will be

$A(t)=(0.902)^t A_0$

And by substituting the value of A0, we can find an explicit expression:

$A(t)=(0.902)^t \cdot 1500$ $[km^2]$

PLZ HELP!!!! There is a box in your kitchen pantry that is a rectangular prism. Its volume is 64 cubic inches. How many differen

WINSTONCH [101]

We know that the volume of a rectangular prism is given by:
V = A · h
where:
A = surface area
h = height

Therefore, you can solve for A:
A = V / h
= 64 / h

Now, you need to ask yourself by how many numbers you can divide 64. The possible heights are 64, 32, 16, 8, 4, 2 and 1.

Hence:
A) there are 7 possible surface areas (one for each possible height).

B) the <span>maximum Area will be that of the box with the minimum height:
A = 64 / 1 = 64

C) the minimum Area will be that of the box with the maximum height:
A = 64 / 64 = 1</span>
