This is the floor plan of Andrew’s toy room. Andrew needs to determine the area of the floor so he can order new wood flooring. Enter the area, in square feet, of Andrew’s toy room floor.
Answer:
should be 76
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*7=35
rec 2: (8-3.5)*(11-5-4)=9
rec 3:4*8=32
Then:
35+9+32=76

the radius of a circle is 6cm what is the diameter circumference and area of the formula?
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.
It is possible none of the choices is the solution?
If I’m wrong, then which one is the correct answer?
Answer:
I am pretty sure the answer would be B!

Write 1.5 : 6 as a whole number ratio in it's simplest from.
Answer: 1.5 : 6 = 1 : 4
Step-by-step explanation: Change values to whole numbers.
Convert any decimal numbers to integers by multiplying both sides by 101 = 10 to eliminate all, 1, decimal places.
We then have:
1.5 : 6 = 15 : 60
Try to reduce the ratio further with the greatest common factor (GCF).
The GCF of 15 and 60 is 15
Divide both terms by the GCF, 15:
15 ÷ 15 = 1
60 ÷ 15 = 4
The ratio 15 : 60 can be reduced to lowest terms by dividing both terms by the GCF = 15 :
15 : 60 = 1 : 4
Therefore:
1.5 : 6 = 1 : 4

Given:
The function is:
[tex]f(x)=-2x+5[/tex]
To find:
The inverse of the given function, then draw the graphs of function and its inverse.
Solution:
We have,
[tex]f(x)=-2x+5[/tex]
Step 1: Substitute [tex]f(x)=y[/tex] .
[tex]y=-2x+5[/tex]
Step 2: Interchange x and y.
[tex]x=-2y+5[/tex]
Step 3: Isolate variable y.
[tex]2y=5-x[/tex]
[tex]y=\dfrac{5-x}{2}[/tex]
Step 4: Substitute [tex]y=g(x)[/tex].
[tex]g(x)=\dfrac{5-x}{2}[/tex]
Hence, the inverse of the given function is [tex]g(x)=\dfrac{5-x}{2}[/tex] and the graphs of these functions are shown below.
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.
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.

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.
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

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]
