The area of the kitchen is given by multiplying the length by the width

Area = 13.25×7.5 = 99.375 feet²

To make sure that we buy enough tiles, it is best to round the area to the nearest tenth or better still round up to the nearest integer

99.375 in nearest tenth is 99.4
99.375 rounded up to the nearest integer is 100

Monet measures the diameter of an Oreo and finds that each cookie is 1.75 inches across. Using Monet's measurement, calculate th
Anon25 [30]

Answer:

5.495 inches.

Step-by-step explanation:

We have been given that Monet measures the diameter of an Oreo and finds that each cookie is 1.75 inches across. We are asked to find the circumference of an Oreo.

We know that circumference of circle is equal to 2\pi r, where r represents radius of circle.

We also know that diameter is 2 times radius.

D=2r

Upon substituting 2r=\text{ 1.75 in}, we will get:

\text{The circumference of an Oreo}=\text{ 1.75 in}\times \pi

Using 3.14 as an estimation for π, we will get:

\text{The circumference of an Oreo}=\text{ 1.75 in}\times 3.14

\text{The circumference of an Oreo}=5.495\text{ in}

Therefore, the circumference of an Oreo would be 5.495 inches.

Which of the following shows one way to simplify 43Σn=1(3+9n)?
kramer

Based on the given summation notation, the expression that shows one way to simplify 43 Σ n=1 (3+9n) is (a) 43 Σ n=1 3 + 43 Σ n=1 9n

<h3>How to determine the summation expression?</h3>

The expression is given as:

43Σn=1(3+9n)

As a general rule, if a summation notation is represented using the following expression

Σ(a + bn)

The equivalent expression of the above summation notation is

Σa + bn

Where the variable a is a constant in the expression

This means that:

Σ(a + bn) = Σa + bn

Using the above equation as a guide, we have the following equivalent equation

43 Σ n=1 (3+9n) = 43 Σ n=1 3 + 43 Σ n=1 9n

Hence, based on the given summation notation; the expression that shows one way to simplify 43 Σ n=1 (3+9n) is (a) 43 Σ n=1 3 + 43 Σ n=1 9n
