poizon [28]

3/8 of the animals are birds
of the birds: 4/15 are birds of prey

If you want to know what fraction of the animals at the zoo are birds of prey, you can calculate this using the following steps:

4/15 * 3/8 = 12 / (15*8) = 1 / (5*2) = 1 / 10 = 0.1

Result: In the town zoo, 1/10 of animals are birds of prey.

Find the surface area of a sphere with a diameter 18 cm. Round your answer to the nearest hundredth.

lions [1.4K]

Answer:

1017 sq. cm

Step-by-step explanation:

Surface area:

The surface area of a sphere with radius r is given by:

$S = 4\pi r^2$

In this question:

Diameter of 18, since the radius is half the diameter, $r = \frac{18}{2} = 9$

The surface area is:

$S = 4\pi*9^2 = 1017$

So 1017 square centimeters, and the best option is b.

Create a pattern with the rule n×2+1

Sauron [17]

Answer:

The rule (n×2+1) gives the sequence of odd numbers {.... , -5, -3, -1, 1, 3, 5, ....}.

Step-by-step explanation:

We have the expression 'n×2+1'.

It is required to find a pattern obtained by the expression.

Substituting values of 'n' gives,

For n = -3, we get (n×2+1) = (-3×2+1) = -6+1 = -5

For n = -2, we get (n×2+1) = (-2×2+1) = -4+1 = -3

For n = -1, we get (n×2+1) = (-1×2+1) = -2+1 = -1

For n = 0, we get (n×2+1) = (0×2+1) = 1

For n = 1, we get (n×2+1) = (1×2+1) = 2+1 = 3

For n = 2, we get (n×2+1) = (2×2+1) = 4+1 = 5

So, we see that, substituting the value of n, the result comes out to be an odd number.

Hence, the rule (n×2+1) gives the sequence of odd numbers {.... , -5, -3, -1, 1, 3, 5, ....}.
