Formula for the area of a triangle.
A = B*H/2
Formula for the area of a rectangle.
A = L*W
1. Break up the shape into 1 triangle and 1 rectangle.
2. The length of the rectangle is 8 ft and the width is 3 ft. Plug-in these values into the formula for the area of a rectangle.
A = 8 * 3
A = 24
3. The base of the triangle is 8 ft and the height is 4 ft. Plug-in these values into the formula for the area of a triangle.
A = (8 * 4) / 2
A = 32 / 2
A = 16
4. Now add the two areas together to find the amount of carpet needed.
24 + 16 = 40
Answer:
38 ft²Step-by-step explanation:
You can take it as combination of two figures, a trapezoid and a triangle.
Trapezoid has bases 12 ft and 8 ft and height 3 ft
Its area is
A = 1/2(8 + 12)(3) = 30 ft²Triangle has height 4 ft and base 4 ft,
Its area is
A = 1/2(4*4) = 8 ft²Total area is
30 + 8 = 38 ft²Related Questions

Both circles have the same center. The
circumference of the inner circle is
249.944 meters. What is the area of the
shaded region?
Answers
First, to find the area of the smaller circle, you can use the circumference given to help you find that. Since the formula for Circumference is C=2rpi, you can solve for the radius by doing 249.944/(2*3.14).
The radius of the smaller circle will end up being 398/15 m as a fraction, and 26.53 rounded to the nearest hundredth.
Now since you have that, you can use the are of a circle formula to find the bigger and smaller circles.
A=pi(r)^2
For the smaller circle: 3.14*(26.53)^2
= 2210.06 meters squared
For the bigger circle: 3.14*(49+26.53)^2
= 17913.01 meters squared
Now subtract them:
17913.01-2210.06 = 15702.95
The area of the shaded is 15702.95

What is the standard deviation of the shoe size data for the math class? 1.5 2.7 3.0 3.8
Answers
The standard deviation is the maximum and the minimum variation in the data set from the mean. The value of the standard deviation is 1.5.
What is a standard deviation?The standard deviation is the maximum and the minimum variation in the data set from the mean.
Given that the mean shoe size is 7.5, while the size of shoe for the entire class is only 1 deviation, and the value is 6 and 9. Therefore, the equation of the standard deviation and the mean can be written as,
[tex]\mu -\sigma < x < \mu +\sigma \\6 < x < 9[/tex]
Now, the value of the standard deviation can be written as,
[tex]\mu - \sigma = 6\\\\-\sigma = 6-7.5\\\\-\sigma = -1.5\\\\\sigma = 1.5[/tex]
or the value of the standard deviation can be written as,
[tex]\mu + \sigma = 9\\\\ \sigma = 9-7.5\\\\ \sigma = 1.5[/tex]
Hence, the value of the standard deviation is 1.5.

ABC is equilateral, each angle has a measure of 9x-12
Answers
Answer:
x=8
Step-by-step explanation:
Angles in a Triangle always add up to 180
So, 3(9x-12)=180
27x-36=180
216=27x
x=8
The angle of the equilateral triangle is 60° and x is 8.
What is a Triangle?A triangle is a polygon with three sides and three vertices.
The triangle's total number of angles comes to 180°.
Given, measure of angle of an equilateral triangle 9x-12.
The sum of all the angles of the triangle is 180°.
That means,
3(9x-12) = 180°
27x = 180+36
x = 216 / 27
x =8

Answers
Answer:
a. 2 7/9 miles
b. 21.6 minutes
c. 8 1/3 miles
Step-by-step explanation:
The rate at which Catlin runs can be determined from the graph by finding the coordinates of a grid point that lies on the line. The line goes through the origin, so the relationship between time and distance is proportional.
We see that the point (miles, minutes) = (1 2/3, 12) lies on the graph, so the contant of proportionality is ...
k = y/x = 12/(5/3) = 36/5 = 7.2 . . . . minutes/mile
__
a.The proportion can be written ...
distance/(20 minutes) = (1 mile)/(7.2 minutes)
distance = (20/7.2) miles = 2 7/9 miles
Catlin will run 2 7/9 miles in 20 minutes
__
b.The proportion can be written ...
time/(3 miles) = (7.2 minutes)/(1 mile)
time = (3)(7.2 minutes) = 21.6 minutes
Catlin was running 21.6 minutes
__
c.In 1 hour, Catlin will run 3 times as far as in 20 minutes. Using the result from part A, we find ...
3(2 7/9 miles) = 8 1/3 miles 8 1/3 miles
Catlin will run 8 1/3 miles in one hour.
_____
Additional comment
Once we have a relationship between minutes and miles, we can write proportions with either of those numbers in the numerator or denominator. We find it convenient to put the unknown value in the numerator of a proportion, which is why the ratios are written differently in the different parts of the problem.

What is the axis of symmetry of the graph of f(x)=−2x²+8x−2?
Answers
For the given parabola, the axis of symmetry is x = 2.
How to get the axis of symmetry?
For any given parabola, we define the axis of symmetry as a line that divides the parabola in two equal halves.
For a regular parabola, we define the axis of symmetry as:
x = h
Where h is the x-component of the vertex.
Remember that for the general parabola:
y = a*x^2 + b*x + c
The x-value of the vertex is:
h = -b/(2a)
Then for the function:
f(x)=−2x²+8x−2
We get:
h = -8/(2*-2) = 2
Then the axis of symmetry is x = 2.

Which property of addition is shown below? a bi c di = a c bi di identity property associative property commutative property inverse property
Answers
The commutative property of addition is shown here a+bi+c+di = a+c+bi+di which is the correct answer.
What is commutative property?The commutative property states that an expression of the form (A + B) can be solved as (B + A) by an addition operation that does not change the result.
This property applies to multiplication also.
We have the given expression:
a+bi+c+di = a+c+bi+di
We have to identify the property of addition in the above expression.
Since we can say here that (bi+c) is expressed as (c+bi).
The commutative property of addition states that the numbers can be added in any order.
Mathematically, it states that a+b = b+a.
Here, (bi+c) can be replaced by (c+bi), whether 'b' is added to 'ci' or 'ci' is added to 'b', the result is always the same.
Therefore, the commutative property of addition is the correct answer
