gulaghasi [49]

Answer: 268

Step-by-step explanation:

From the question, we are informed that 67 out of 206 species of birds found in the Badlands nest there and that 824 species were found in the Badlands. The number of those that nest there would be:

= 67 × 824/206

= 67 × 4

= 268

Susan makes purple paint by mixing red and blue paint in the ratio 2:3

viktelen [127]

25ml — you add up the two numbers in the ratio, and that makes 5 (2+3), you then need to make sure that your answer is a multiple of 5 while being in the ratio 2:3. You then add up the 2 colours of paint

the area of John's garden is the same size of Sarah's garden. John's garden has a width of 9 meters, and Sarah's garden has a wi

Alekssandra [29.7K]

The combined area of both gardens is 72 square meters.

Step-by-step explanation:

Given,

Width of John's garden = 9 meters

Width of Sarah's garden = 6 meters

Let,

l be the length of John's garden.

Length of John's garden = l+2

It is given that area of both gardens is same,

Area of Sarah's garden = Area of John's garden

Length * Width = Length * Width

$6*(l+2)=9*l\\6l+12=9l\\12=9l-6l\\12=3l\\3l=12$

Dividing both sides by 3

$\frac{3l}{3}=\frac{12}{3}\\l=4$

Length of John's garden = 4 meters

Length of Sarah's garden = 4+2 = 6 meters

Combined area = Area of John's + Area of Sarah's

Combined area = (Length * Width) + (Length * Width)

Combined area = (4*9)+(6*6)

Combines area = 36+36 = 72 square meters

The combined area of both gardens is 72 square meters.

The surface area S of a single-celled organism may be found by multiplying 4π times the square of the radius r of the cell. Expr

Arte-miy333 [17]

Answer:

$S(r)=4\pi r^2$ .

Step-by-step explanation:

It is given that, the surface area S of a single-celled organism may be found by multiplying 4π times the square of the radius r of the cell.

We need to express S as a function of r.

Let r be the radius of the cell and S(r) be the surface area of single-celled organism when radius is r.

According to the question,

$S(r)=4\pi \times r^2$

$S(r)=4\pi r^2$

Therefore, the required function is $S(r)=4\pi r^2$ .
