Answer:

B

Step-by-step explanation: Plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again.

If n^-2 = 1/16, then n could be which of the following?

Zepler [3.9K]

Answer:

The correct choice is

$\boxed{n=4}$

Step-by-step explanation:

The given equation is

$n^{-2}=\frac{1}{16}$

We rewrite the left hand side of the equation as a power(a number to a given exponent.

$n^{-2}=\frac{1}{4^2}$

Recall that;

$\frac{1}{a^m}=a^{-m}$

We apply this property to obtain;

$n^{-2}=4^{-2}$

Since the exponents are the same, the bases are also the same.

Therefore $n=4$

Any of these please I’m having difficulty

frosja888 [35]

Answer:

864 squared meters

Step-by-step explanation:

Set up a proportion. The scale between 270 and 360 should be the same as 648 to the fourth yard.

$\frac{270}{360} = \frac{648}{x}\\270x = (360)(648)\\270x = 233280\\x = 864 m^2$

A kitten and a puppy found a sausage which is 14cm long and started eating it simultaneously from each end. The kitten is eating

julsineya [31]

It takes them 12 seconds to eat the whole sausage.

<h3>What is speed?</h3>

Speed is the rate of change of distance.

Analysis:

If kitten eats x cm, then puppy will eat 14 - x cm

speed = d/t

speed of kitten = 1/2

speed of puppy = 2/3

1/2 = x/t

2/3 = 14 - x / t

t = 2x--------1

2t = 3(14 - x ) -------- 2

substitute t in equation 2

2(2x) = 3(14 - x)

4x = 42 - 3x

7x = 42

x = 42/7 = 6cm

substitute value of x in equation 1

t = 2(60 = 12 seconds.

In conclusion, it takes the both animals 12 seconds to finish the sausage.

What is the area of the polygon defined by the points A(12, 20), B(20, 20), C(20, 8), and D(12, 8)? a 96 square units b 132 squa

Leto [7]

Answer:

a. 96 square units

Step-by-step explanation:

The figure is a rectangle with width AB = (20-12) = 8 units and height BC = (20-8) = 12 units.

The area of the rectangle is (8 units)×(12 units) = 96 square units.
