Answer:

Step-by-step explanation:

Calculate the area of the entire rectangle 5 x 10 = 50 square inches.

Subtract the two non-shaded rectangles measuring 3 by 4 which is 3x4 = 12 square inches.

50 - 12 - 12 = 26 square inches.

8x -y=2. 5x-4y=3 please help solve this system by substition method

Vitek1552 [10]

8x-y=2 ---> y=8x-2
5x-4y=3

5x-4(8x-2)=3
5x-32x+8=3
-27x+8=3
-27x=-5
x= 5/27

8(5/27)-y=2
40/27-y=2
y=-14/27

Answer:

$\Huge\boxed{25.13ft^3}$

Step-by-step explanation:

Hello There!

It says the tree has a cone like structure

The formula for volume of a cone is

$V=\pi r^2\frac{h}{3}$

where r = radius and h = height

note it says to use 3.14 for pi

so given the dimensions all we have to do is plug in the values into the formula

$V=3.14*2^2*\frac{6}{3}\\2^2=4\\4*3.14=12.56\\\\\frac{6}{3} =2\\2*15.56=25.133$

Our last step is to round to the nearest foot

So we can conclude that the tree has a volume of 25.13ft³
