Answer:

80,000,000

Step-by-step explanation:

The difference between 10,000,000 and 50,000,000 is 40,000,000 per hectare. The question states two hectares, so 40,000,000 x 2 is 80,000,000.

Hope that helps.

Calculate the volume and total surface area

nikdorinn [45]

Answer:

Below.

Step-by-step explanation:

a. Volume = area of triangular side * length

1/2 * 3 * 4 * 8

= 48 cm^3.

Surface area = 2 * area of the triangle + area of sloping side+ area of the base + area of the back side

= 2 * 1/2 * 3*4 + 5*8 + 3*8 + 4*8

= 12 + 40 + 24 + 32

= 108 cm^2.

b. Volume = area of the triangular side * length

= 1/2 * 5.0 * 5..0 * 8.2

= 12.5 * 8.2

= 102.5. cm^3.

Surface area = 2 * area of the triangle + 2 * area of a sloping side + area of the basee

= 2 * 1/2 * 5^2 + 2 * 5 * 8.2 + 8.2 * 7.1

= 25 + 82 + 58.22

= 165.22 cm^2.

If m(x)=x 5/x-1 and n(x) = x – 3, which function has the same domain as (m*n)(x)

Tatiana [17]

Answer:
m(x) has the same domain as (m*n)(x)

Explanation:
1- For m(x):
m(x) is a fraction. This means that the denominator cannot be zero, otherwise, the fraction would be undefined.
The denominator of m(x) would be zero at x = 1.
This means that the domain of m(x) can be any real number except 1

2- For n(x):
The value of x in n(x) can be any number. This is because there is no value that would make n(x) undefined.
This means that the domain of n(x) is all real numbers

3- For (m*n)(x):
(m*n)(x) = m(x) * n(x) = $\frac{x-5}{x-1} *(x-3) = \frac{(x-5)(x-3)}{(x-1)}$

We can note that the product is also a fraction. This means that the denominator cannot be zero.
The denominator here will be zero at x = 1.
This means that the domain of (m*n)(x) is all real numbers except 1.
This is the same as the domain of m(x)

Hope this helps :)

What is the surface area of a coke bottle? how do you figure it out?

svetlana [45]

Can or bottle? A can will be the calculation for the surface area of a cylinder which is A= $2 \pi rh+2 \pi r^{2}$ if r is the radius of the circle on the top and bottom of the can and h is the height of the can. A can is basically two circles and a big rectangle. For a bottle I don't know there are too many components and no numbers to solve for that
