Answer
72-30=42. The answer is 42
Step-by-step explanation:
to find the area of this, we first need to add are to the missing space, so we can make a rectangle. If we multiply the dimension of this new shape, we get 72. Now we need to find the are of the triangle-shaped space I added. To do this I must multiply the base by the height, and then divide it by 2, after multiplying the base with the height, which gave me 60, I divided it by 2 which gave me 30. Then I subtracted 30 from 72, therefore giving me 42
Answer:
42cm2
Step-by-step explanation:
You can divide the shape into two parts from the length at the top and the length at the bottom. Which means you have two shapes A and B.
Area of A which is a triangle= 1/2bh
= 1/2*5(THIS IS THE BASE OF THE TRIANGLE)12
= 30CM2
Area of b which is a rectangle= L*W
= 1(LENGTH) * 12(WIDTH)
= 12CM2
So to get the total area of the shape you add the area of shape a and b
THE ANSWER IS 42cm2

George is designing ledges for the octagonal ( 8 side ) gazebo. All sides are equal length, and each ledge much be 18 inches shorter then the sides.
a: what is the minimum length of wood he should purchase if the perimeter of the gazebo is 64 feet ?
b : what as your solution process
Answer:
78 inches or 174 inches (see explanation)
Step-by-step explanation:
If the perimeter is 64 feet, that means that each side is 8 feet, since there are 8 sides (64/8=8). 8 feet is 96 inches (8*12=96). 96-18=78, so the minimum length of wood he needs for the ledges is 78 inches, assuming you're not counting the wood for the perimeter, too (in which case it would be 174 inches) (78+96=174).

Find the perimeter and area of the shaded region.
Answer:
Perimeter of the shaded region= 22/7cm
Area = 36.48 cm²
Step-by-step explanation:
First of all for the perimeter.
The radius of the arc is 8cm
At an angle of 90°
Perimeter of of the shape is perimeter of the the 2 arc
The both arc are equal so let's determine the perimeter of one first.
Perimeter of the arc= 2πr*(90/360)
Perimeter of the arc= 2*22/7*1/4
Perimeter of the arc= 11/7 cm
Perimeter of the shades region= 2*11/7
Perimeter of the shaded region= 22/7cm
Area of the sector = πr²*(90/360)
Area of the sector= 50.24cm²
Area of non sector= 64-50.24
= 13.76
But non sector is two
Area of non sector= 2*13.76
= 27.52
Area of the shaded region = area of the square -(area of non sector)
= 64-27.52
= 36.48 cm²
Part 1: Serena's drawing
Follow these steps to find the angles of the trapezoids in Serena's drawing. If the angles of her
trapezoid match the angles of the trapezoid stone, then her drawing is correct.
Answer:
BCDE= 100+ 80+100+80 = 360 degree
BAC = 20 degree
DBC = 100 degree
BDE = 80 degree
Shows all is correct
We associate isosceles trapezoid in this question, this helps us prove with angle A in the triangle vertices how we can find one of the adjacent angles from the trapezoid by subtraction when all angles within one single trapezoid = 360 degrees. We can use 20 degree angle A to subtract and find each alternative angle easier.
Step-by-step explanation:
The semi circle shows 9 stones
Where angles are interior to the trapezoid
Where all 4 sided shapes add up to 360 degree
We draw a line of symmetry on BCED angle
To make midway points BC and DE = 90 degree
The two new formed shapes are still 4 sided and add up to 360 degree.
BC + DE = 180 degree
BDE = Triangle 180 -20/2 = 160/2 = 80
BCDE = Trapezoid = 360
Trapezoid angle DBC = 360-80-80/2 = 360-160/2 = 200/2 = 100 degree
Finding interior angle A (BAC)
BAC = 180/9 = 20 degree
BAC * (2) = 360 degree circle
BAC = 360/18 = 20 degree
Proves BAC = 20 degree
20 degree is used in BAC workings above in bold and proves all trapezoid angles are correct. We now know this is an isosceles trapezoid and that is why symmetry and midway points can help us find the angles without any given length.

Answer:
The answer is option BStep-by-step explanation:
To find the side adjacent to the 50° angle we use tan
[tex] \tan( \alpha ) = \frac{opposite}{adjacent} [/tex]
From the question
The opposite is 6m
The adjacent is ?
So we have
[tex] \tan(50) = \frac{6}{?} [/tex]
[tex]? \tan(50) = 6[/tex]
[tex]? = 6 \times \frac{1}{ \tan(50) } [/tex]
But
[tex] \frac{1}{ \tan(x) } = \cot(x) [/tex]
So we have
[tex] \frac{1}{ \tan(50) } = \cot(50) [/tex]
Substitute it into the expression
That's
We have the final answer as
[tex]? = 6 \cot(50) [/tex]
Hope this helps you
=====================================================
Explanation:
We're given an opposite side and an adjacent side. The tangent rule ties these two sides together. "tangent" is nowhere to be found in any of the answer choices, but cotangent is. Recall that
cot = 1/tan
which means
tan = opposite/adjacent
cot = adjacent/opposite
one is the reciprocal of the other
-----------
This means
cot(angle) = adjacent/opposite
cot(50) = x/6
6*cot(50) = x
x = 6*cot(50)

Find the distance between the points X and Y shown. Question 5 options: A. 29−−√ B. 21−−√ C. 21 D. 5–√
Answer:
A
Step-by-step explanation:
From the graph we can notice that the coordinates of the poinrs x and y are:
● x(-2,0)
● y(3,-2)
There are many methods to find the distance between x and y. We will use the distance formula.
Let d be the distance between x and y.
● d = √[(-2-3)^2 + (0-(-2))^2]
● d = √[(-5)^2 + 2^2]
● d = √(25+ 4)
● d = √(29)
The other method was using the pythagorian theorem. d is the hypotenus.

How many envelopes does Jane address in a
day?
Jane addresses twice as many envelopes
as Louis in the same amount of time.
Together, they address 450 envelopes
each day.
Answer:
2x+X=450
3x=450
X=450/3
X=150
so
2x=2*150=300
X=150
so, Jane addressed 300 envelopes while Louis addressed only 150
Answer:
Jane addressed 300 envelopes while Louis addressed 150
Step-by-step explanation: Let x represent Louis's amount and 2x is Jane's amount
x+2x= 450 combine 3x =450
Divide both sides by 3.
x/3 = 450/3 x= 150. 2x = 300

-31-4x=-5-5(1+5x) I need help i suck at math
Answer:
x = 1
Step-by-step explanation:
−31−4x=−5−5(1+5x)
First step is to simplify both sides
−31−4x=−5−5(1+5x)
−31+−4x=−5+(−5)(1)+(−5)(5x)
distribute
−31+−4x=−5+−5+−25x
−4x−31=(−25x)+(−5+−5)
and combine like terms
−4x−31=−25x+−10
−4x−31=−25x−10
Then add 25x to both sides
−4x−31+25x=−25x−10+25x
21x−31=−10
Add 31 to both sides
21x−31+31=−10+31
21x=21
And divide by 21!
21x/21 = 21/21
x=1
Answer:
X=1
Step-by-step explanation:
First this is you want to distribute the -5 to the 1 and 5x. Now you should have -31-4x=-5-5-25x. Next thing is to combine your like terms which would be -5 and -5 and you get -10. (-31-4x=-10-25x) Now add 31 to both sides and your new solution is -4x=21-25x. This time you add 25x to both sides and get 21x=21. Final step you divide both sides by 21 and get X=1. :)

T(d) is a function that relates the number of tickets sold for a movie to the number of days since the movie was
released. The average rate of change in Td) for the interval d = 4 and d = 10 is 0. Which statement must be true?
O The same number of tickets was sold on the fourth day and tenth day.
O No tickets were sold on the fourth day and tenth day.
O Fewer tickets were sold on the fourth day than on the tenth day.
O More tickets were sold on the fourth day than on the tenth day.
Answer: The same number of tickets was sold on the fourth day and tenth day.
Step-by-step explanation:
Given, T(d) is a function that relates the number of tickets sold for a movie to the number of days since the movie was released.
The average rate of change in a function with respect to the independent variable gives the value of change in a particular period.
If average rate of change in T(d) for the interval d = 4 and d = 10 is is 0 , that means nothing has been changed in the number of tickets sold on 4th day and 10th day after the film release.
Hence, the correct statement is "The same number of tickets was sold on the fourth day and tenth day."
The correct option is (A).The same number of tickets was sold on the fourth day and tenth day.
Given,
T(d) is a function that relates the number of tickets sold for a movie to the number of days since the movie was released.
The Average rate of change in T(d) for the interval d = 4 and d = 10 is 0.
We have to find which statement is true.
Since the average rate of change in T(d) for the interval d = 4 and d = 10 is 0, it means nothing has been changed in the number of tickets sold on day 4 and day 10 after the film release.
Hence, the correct statement is The same number of tickets was sold on the fourth day and tenth day.
Thus The correct option is A.

Find the lateral area of the following cone.
Leave your answer in terms of pi
Answer:
The lateral surface area of cone is A = π×r×l where r represents radius and l is slant height.
The formula to find slant height is l = √(h²+r²) where h represents height.
The lateral surface area of the cone is 65[tex]\pi[/tex] square cm.
Given,
The height is 12 cm and the radius is 5 cm.
We are to find the lateral surface area of a cone.
What is the lateral surface area of a cone?The lateral surface area of a cone:
A = [tex]\pi[/tex] x r x l
where r = radius and l = slant height.
The slant height:
l = √(h²+r²) where h =height.
We have,
h = 12 cm and r = 5 cm
l =√(h²+r²)
l = √(12^2 + 5^2)
l = √(144 + 25)
l = √169
l = 13 cm
Now,
l = 13 cm and r = 5 cm
A = [tex]\pi[/tex] x r x l
A = [tex]\pi[/tex] x 13 x 5 = 65[tex]\pi[/tex] square cm
Thus lateral surface area of the cone is 65[tex]\pi[/tex] square cm.
