5(3x-6) is equivalent to 15x - 30 if they are equivalent if the two values are the same.

<h3>What is expression?</h3>

An expression is a set of terms combined using the operations +, – , x or , /.

Given expression:

5(3x-6) is equivalent to 15x - 30.

If we put x=2 in both expression, we get finite value.

To check both the expression are equal or not we have to solve by putting the value.

So,

They are equivalent if the two values are the same otherwise not.

A boat is heading towards a lighthouse, whose beacon-light is 139 feet above the

Novay_Z [31]

The horizontal distance between light house and boat is 1588.78 feet approximately.

The figure is given by,

Here, AB = height of the lighthouse bacon light above the water = 139 feet

Now angle ACB = 5 degree

Let the horizontal distance of light house from the boat = BC = x feet

So by trigonometric function we get,

tan 5 = AB/BC

tan 5 = 139/x

x = 139/tan 5 = 1588.78 (approximately)

Hence the horizontal distance between light house and boat is 1588.78 feet approximately.

Answer: Marci: 60 minutes

Bobby: 30 minutes

Max: 90 minutes

Step-by-step explanation:

50% of 60 is 30.

100% of 60 is 60, plus 50% is 60+30, which gets you 90.

A cone with a height of 50 meters has a volume of 5400π meters cubed. What is the radius of the cone?

Sergeu [11.5K]

Answer:

Step-by-step explanation:

The volume of a cone has the formula:

$V=\frac{1}{3}\pi r^2 h$

Where

V is the volume

r is the radius

h is the height

Given,

h = 50

V = 5400π

We want the radius, r.

Lets substitute and solve for r:

$V=\frac{1}{3}\pi r^2 h\\5400\pi=\frac{1}{3}\pi r^2(50)\\5400\pi=\frac{50\pi r^2}{3}\\50\pi r^2=16200\pi\\r^2=324\\r=\sqrt{324}\\r=18$

The radius is 18 meters
