Hey there!

if i am doing this correct it should be

17/50, let me explain!

.34 is 34/100 and both of these numbers are even, thus you can divide it by 2 which will give you 17/50

A rectangular block of copper metal has a mass of 1800 grams. The dimensions of the block

Hoochie [10]

Use formula p=m/v
P is density
M is mass
V volume
So you have the volume already now 8x5x4= 160 which is the volume
P= 1800/160 after you divide you get 11.25
The density is 11.25

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:

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

What is the pythagorean theorem?

Natalija [7]

Easy,

the Pythagorean theorem is:

$a^{2} + b^{2} = c^{2}$

The a and b, being a value that you HAVE

and

c, being the value you are trying to find.

Example: have 1,2 for a triangle what is the third side?

$1^{2} + 2^{2} = c^{2}$

1+4= $c^{2}$

5= $c^{2}$

Then, just square root to find c.

$\sqrt{5}$ =c

2.2≈c
