Answer:

Step-by-step explanation:

I'm not sure if the right side is $\frac{a + b}{2}$ or $a + \frac{b}{2}$ , so I'll provide an answer for both:

$A = \frac{a + b}{2}$

$2A = a + b$

$2A - a = b$

$A = a + \frac{b}{2}$

$A - a = \frac{b}{2}$

$2(A - a) = b$

$2A - 2a = b$

A = a +b/2
A -a =b/2
2(A-a) = b

The circumference of the base of a cone is 24 inches. The slant height of the cone is 20 inches. What is the surface area of the

nignag [31]

Answer:

Step-by-step explanation:

Given data:

Circumference of the base of the cone = 24in.

Recall that circumference (in this case) is the distance round the base of the cone and from here the diameter D=12in. Radius = 6in

Surface area l = pie x radius ( slant height + radius)

= 3.142 x 6 (20 + 6)

= 3.142 x 6 (26)

= 3.142 x 156

= 490.152in^2

What is the simplified form of √144x^36

Nadusha1986 [10]

Answer:

The simplified form of $\sqrt{144x^{36}}$ is $12x^{18}$

Step-by-step explanation:

Given : $\sqrt{144x^{36}}$

We have to write the simplified form of $\sqrt{144x^{36}}$

Consider the given expression $\sqrt{144x^{36}}$

We know $\sqrt{144}=12$

and $\sqrt{x^{36}}=\sqrt{x^{18}\cdot x^{18}}$

Thus,

$\sqrt{144x^{36}}=\sqrt{12^2\cdot (x^{18})^2}$

Simplify, we have,

$=\sqrt{12^2\cdot (x^{18})^2}=12x^{18}$

Thus, The simplified form of $\sqrt{144x^{36}}$ is $12x^{18}$

a 1 kg ball has 10 joules of kinetic energy and starts to roll up a hill how far up the hill will it be when it stops

AURORKA [14]

Answer:

Step-by-step explanation:

A 1 kg ball has 10 joules of kinetic energy and starts to roll up a hill.

As along the hill the ball rises up, it loses its kinetic energy. The kinetic energy is converted to potential energy.

According to the law of conservation of energy, the kinetic energy plus the potential energy equals a constant.

Here given kinetic energy as 10 J, so this energy will get converted to potential energy.

We know that, potential energy is

$P.E=m\cdot g\cdot h$

where,

m is the mass, g is the acceleration due to gravity and h is the height.

Putting the values,

$\Rightarrow 10=1\times 10\times h$

$\Rightarrow 10=10 h$

$\Rightarrow h=1\ m$
