What does 18x12x1000 equal to?

Answers

18(12)=216
Because 1000 has 3 zeros, add 3 zeros after 216. Answer is 216,000

First, we calculate 18 x 12

18 x 12 = 216.

To multiply a number by 1000, we add 3 zeros after it.

So, 216 x 1000 = 216000

-> 18 x 12 x 1000 = 216000.

This cylindrical fish tank has a height of 38 inches and a diameter of 26 inches. What is the volume of the fish tank? Use 3.14 for . Round to the nearest inch.

Answers

The volume of the fish tank having height 38 inches and diameter 26 inches = 20,165.08 [tex]inch^{3}[/tex]

What is Volume of cylinder?

The volume of a cylinder is the number of unit cubes (cubes of unit length) that can be fit into it. It is the space occupied by the cylinder as the volume of any three-dimensional shape is the space occupied by it.

The height of the fish tank = 38 inches

Diameter = 26 inches

Radius of fish tank = 13 inches

Volume of the fish tank =[tex]\pi* r^{2}*h[/tex]

                                         = 3.14 x 13 x13 x 38

                                         = 3.14 x 169 x 38

                                         = 20,165.08 [tex]inch^{3}[/tex]

If data is normally distributed and has μ = 90 and o-10, what is the z-score for a data value of 75?

Answers

Answer:

The z-score for this data is -1.5

Step-by-step explanation:

Step 1: For the specified distribution and data point,

μ = 90, σ = 10, and x = 75 (given)

Step 2: We now apply the z-score formula:

z = x − μ / σ

z = 75 - 90 / 10

z = - 15 / 10

z = -1.5

We can take it a step further:

A z-score table shows the percentage of values (usually a decimal figure) to the left of a given z-score on a standard normal distribution

percentage of value = 0.0668

The selling price of an item is ​$720. It is marked down by ​30%, but this sale price is still marked up from the cost of ​$420. Find the markup from cost to sale price.

Answers

The markup cost is $84 if the selling price of an item is ​$720. It is marked down by ​30%, but this sale price is still marked up from the cost of ​$420.

What is markup price?

Markup pricing is the practice in which the price of products or commodity is determined by taking all the goods together and adds a fraction as a markup.

We have:

The selling price of an item is ​$720. It is marked down by ​30%

[tex]\rm = 720\times \dfrac{30}{100}[/tex]

Markdown = 216

Now subtract it from the selling price:

= 720-216

Sale price = 504

Now,

= 504-420

Markup cost =  $84

Thus, the markup cost is $84 if the selling price of an item is ​$720. It is marked down by ​30%, but this sale price is still marked up from the cost of ​$420.

The diameter of a circle is 26 cm. Find its area to the nearest whole number.

Answers

area= pi x r^2
= pi x 13^2
=pi x 169
= 530.929
= to the nearest whole number 531

Answer:

531

Step-by-step explanation:

The area of a circle can be determined by the equation: A = πr².

The "r-value" represents the radius, which is half of the diameter. Since the diameter is in cm, the area will have the unit cm².

d = diameter       r = radius       π = 3.14.....       A = area

d / 2 = r

26 / 2 = r

13 cm = r

A = πr²

A = π(13)²

A = 169π

A = 530.929.... cm²

A = 531 cm²

As you can see, the radius was determined to be 13 cm. When you plug that value into the area equation, you get 530.9 cm². Rounding to the nearest whole number would bump the 0 to 1, making the final answer 531 cm².
