The figure shown is created by joining three rectangles. Enter the area of the figure, in square centimeters. Round to the nearest hundredth.

Answers

Answer 1

Answer:

46.75

Step-by-step explanation:

first, separate the floor into 3 different rectangles to calculate the area and then add them together.

area of rec=L*B

rec 1: 5.5*4=22

rec 2: (6.5-3)*(8.5-3-4)=5.25

rec 3:3*6.5=19.5

Then:

22+5.25+19.5=46.75

Step-by-step explanation:

the radius of a circle is 6cm what is the diameter circumference and area of the formula?

Answers

Answer:

Diameter: 12

Circumference: 37.68

Area: 113.04

Step-by-step explanation:

The radius of the circle is 6 cm.

To find the diameter of a circle, multiply the radius by 2.

6 × 2 = 12.

12 is the diameter.

----------------------------------------------------------------------------------------------------------------

Formula for the circumference of a circle: πd (diameter).

In other words, to find the circumference of a circle, multiply the diameter by pi.

**3.14 IS A SUBSTITUTE FOR PI**

12 × 3.14 = 37.68

Therefore, 37.68 cm is the area of the circle.

----------------------------------------------------------------------------------------------------------------

Formula for area of a circle: πr² (r = radius).

3.14 × 6 × 6 = 113.04

Therefore, 113.04 cm² is the area of the circle.

Answer:

[tex]n^2 + \frac{2n}{3} + \frac{1}{9} = \frac{1}{9}[/tex] --- Trinomial

[tex](n + \frac{1}{3})^2 = \frac{1}{9}[/tex] --- Binomial

Step-by-step explanation:

Given

[tex]n^2 + \frac{2n}{3}[/tex]

Solving (a): Perfect square trinomial

We have:

[tex]n^2 + \frac{2n}{3}[/tex]

Express as an equation

[tex]n^2 + \frac{2n}{3} =[/tex]

Start----------------------------

Take coefficient of n i.e. (2/3)

Half it: i.e. (1/3)

Square it: (1/63^2

Add to both sides of the equation

---------------------------End

So, we have:

[tex]n^2 + \frac{2n}{3} + (\frac{1}{3})^2 = (\frac{1}{3})^2[/tex]

Remove brackets

[tex]n^2 + \frac{2n}{3} + \frac{1}{9} = \frac{1}{9}[/tex]

Solving (b): Binomial Squared

[tex]n^2 + \frac{2n}{3} + \frac{1}{9} = \frac{1}{9}[/tex]

Expand

[tex]n^2 + \frac{n}{3}+ \frac{n}{3} + \frac{1}{9} = \frac{1}{9}[/tex]

Factorize:

[tex]n(n + \frac{1}{3})+ \frac{1}{3}(n + \frac{1}{3}) = \frac{1}{9}[/tex]

Factor out n + 1/3

[tex](n + \frac{1}{3})(n + \frac{1}{3}) = \frac{1}{9}[/tex]

Express as square

[tex](n + \frac{1}{3})^2 = \frac{1}{9}[/tex]

Paula dives into a swimming pool from a diving board 2 feet above the water's surface. She descends to a depth 7 feet below the diving board. How far is Paula from the surface of the water:
1. What integer represents Paula's starting height above the water?

2. What integer represents the total distance Paula descends?

3. Write an addition expression to represent Paula's distance below the water's surface

4. At the end of her dive, Paula is ____feet below the surface of the water

5. Yolanda owes her friend $15. She also earns $8 each week in allowance. Write and solve an addition equation to show how the total amount of money that Yolanda has will change if she pays her friend back this week.

Answers

1) The integer representing Paula's starting height above the water is 2.

2) The integer that represents the total distance Paula descends is 7.

3) An addition expression to represent Paula's distance below the water's surface is 2 + 3.

4) At the end of her dive, Paula is 5 feet below the surface of the water.

5) If Yolanda pays her friend back this week, she will owe her only $7.

What is an integer?

An integer is a whole number. It can be positive, negative, or zero but without fractions.

Addition expressions combine two or more addends with the addition operand and equation mark (=) to determine the sum (or the result of the addition operation).

Paula:

Height of diving board = 2 feet

Depth of descent below the diving board = 7 feet

Distance below the water's surface = 5 feet (7 - 2)

5 feet = 2 + 3

Yolanda:

Debt to a friend = $15

Earnings per week = $8

Total amount after paying friend = 8 - 15

= -$7

A paper concluded that there was a correlation between refined sugar consumption (calories per person per day) and annual rate of major depression (cases per 100 people) based on data from six countries. The following data were read from a graph that appeared in the paper.

Country Sugar Consumption Depression Rate
Korea 140 2.4
United States 310 3.1
France 360 4.5
Germany 385 5.1
Canada 400 5.1
New Zealand 470 5.8

Required:
a. Calculate the correlation coefficient for this data set.
b. Interpret the correlation coefficient for this data set.
c. Is it reasonable to conclude that increasing sugar consumption leads to higher rates of depression? Explain.

Answers

Answer:

Following are the responses to these question:

Step-by-step explanation:

In point a:

In the excel sheet with the information, you've been provided. The below is the output of the [tex]CORREL(B2:B7, C2:C7)[/tex] formula for determining correlation coefficients:

[tex]\to r=0.0762[/tex]

It was a good thing that there's a connection between the two. For both depression and sugar intake, there is a weak positive linear relationship.

In point b:

Yes, It's fair to assume which increased sugar intake leads to increased depression rates.

In point c:

Yes, This sample of countries does not appear to be reflective of an entire world. As a result, the inference could be applied to all countries.

A submarine was 350 feet below sea level. Then, it rose 75 feet, before diving back down another 100 feet. What is the current elevation of the submarine?

Answers

The submarine would be 375 feet below sea level.

Since this is talking about BELOW sea level, you would subtract 75 from 350 instead of adding, which would give you 275. Then, you would add 100 to that instead of subtracting, which gives to 375.
