Answer:

x = 90,

3x = 270

Step-by-step explanation:

We have a polygon that has 6 sides. We need to use the formula [tex]S=(n-2)*180[/tex] so we can create an algebraic equation to solve for x.

n = number of sides

[tex]S=(6-2)*180[/tex]

Evaluate

[tex]S=720[/tex]

Now we need to create an algebraic equation to find the value of x.

[tex]3x + x +45+135+45+135=720[/tex]

Add like terms

[tex]4x+360=720[/tex]

Subtract 360 on both sides

[tex]4x=360[/tex]

Divide by 4

[tex]x=90[/tex]

The value of x = 90.

To solve for 3x, the equation means 3 * x. We know what x is, so we just plug in 90.

[tex]3*90=270[/tex]

[tex]3x=270[/tex]

To check our work, add up all angle measures to see if they add up to 720.

[tex]270+90+45+135+45+135=720[/tex]

Answer:

Step-by-step explanation:

1)first lets figure what the rate at which they are traveling is. we know that the have traveled 1 and 3/4 miles in 2 and 1/3 minutes. lets now convert this to miles per 1 minute. we can find this by taking our distance traveled and dividing it by out time taken.

(1 and 3/4) / (2 and 1/3)= .75 or (3/4)

2) now we can take this number and multiply it by 33 minutes to get 24.75 miles

3) we can then multiply .75 by 60 minutes to get that the care has traveled 45 miles in 1 hour.

A sculpture is made of solid nickel in the shape of a cone. The sculpture is 84 inches tall, and its base has a diameter of 16 inches. If nickel costs $2.25 per cubic inch, how much did the nickel for the sculpture cost?

Use 3.14 for pi, and do not round your answer.

Answers

The total cost of the nickel for the sculpture is $12,660.48.

We know that the volume of a cone is:

v = 1/3πr²h ......(i)

where r ⇒ radius of the cone

h ⇒ height of the cone

Now, as per the question,

r = diameter/2 = 16÷2 = 8 inches

h = 84 inches

Putting the values in equation (i)

v = 1/3 × 3.14 × (8)² × 84

v = 5626.88 cubic inch

The cost given for nickel = $2.25 per cubic inch

So, the total cost for the nickel used in making the sculpture:

the volume of cone × cost per cubic inch

5626.88 × 2.25 = $12,660.48

Therefore, the total cost for the nickel used is $12,660.48

The volume of the cylinder is 62.83 cubic cm and the volume of. the cone is 20.94 cubic cm.

What is volume?

In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.

here, we have,

We know that,

It should be noted the to calculate the volume of a cylinder, we can use the formula V = πr²h, where r is the radius and h is the height. In this case, the height and radius of the cylinder and cone are the same.

For the cylinder:

Volume = π(2cm)²(5cm)

V = 20π

For the cone, we can use the formula

V = (1/3)πr²h:

V = (1/3)π(2cm)²(5cm)

V = 20/3π cubic cm (exact value)

Hence, to get an approximate decimal value, we can use a calculator to evaluate:

Volume of cylinder ≈ 62.83 cubic cm

Volume of cone ≈ 20.94 cubic cm
