Answer: 120ft
Step-by-step explanation:
To work out the area of this composite shape you would have to work out the two shapes separately. The shape could be split into 2 rectangles.
The formula for the area of a rectangle is base x height.
So, to work out the area of the living room you have to do 15x7=105
Then to work out the area of the foyer, you would have to do 3x5=15
Because you want the area of both of the shapes together, you have to add the two areas of the rectangles together.
So 105+15=120

the sum of two numbers is 38 and their difference is 10 find the numbers
Answers
Answer:
I believe the two numbers are 14 and 24
Answer:
Those numbers are 14 and 24.
Step-by-step explanation:
You can solve this pretty quickly by taking those two facts and combining them:
a + b = 38
a - b = 10
Let's solve the second one for a:
a = 10 + b
Now we can substitute that into the first one:
a + b = 38
(10 + b) + b = 38
2b + 10 = 38
2b = 28
b = 14
To find a, we can plug that back into one of the original equations:
a + b = 38
a + 14 = 38
a = 24
We can also test our answer by plugging the results into the other given equation and see if we get the same value:
a - b = 10
24 - 14 = 10
10 = 10
So we know our answer is correct.

Answers
Answer:
Step-by-step explanation:
Disclaimer it is up the student to verify all the geometry algabra and mathematical formulas and calculation .
cosФ = opp/hyp sinФ = adj/hyp hyp = 10 perimeter = a + b + c
for the 45° right triangle
a = b so 2a² = hyp² perimeter 45 = a + a + hyp
P45 = 2a + hyp a = sin(45) (hyp) = [1/2√2)] (hyp) sin(45) = (√2)/2
P45 = 2([1/2√2)] (hyp) + hyp
P45 = hyp (√2 + 1)
for the 30° right triangle
a = hyp×sin(30) b = hyp×cos(30) perimeter 30 = a + b + hyp
sin(30) = 1/2 cos(30) = (√3)/2
a = hyp(1/2) b = hyp(1/2)(√3)
P30 = a + b + hyp
= hyp(1/2) + hyp(1/2)(√3) + hyp
= hyp[ 1/2 + (1/2)√3 + 1]
= hyp[ 1/2 + (1/2)√3 + 1] factored out the hyp
= (1/2)hyp[ 1 + √3 + 2] factored out a 1/2
P30 = (1/2)hyp[ 3 + √3]
which is greater P45 or P30? vso I set both perimeters equal to each other
P45 vs P30
hyp (√2 + 1) = (1/2)hyp[ 3 + √3] the hyp cancel
(√2 + 1) = (1/2)[ 3 + √3] still tough to tell needed
1.414 + 1 = (1/2)[ 3 + 1.732] to go to the calsulator
2.414 vs 1/2( 4.732)
2.414 > 2.366 thus P45 > P30 < ----- Final Answer

write three to the power of two sevenths in radical form and explain?
Answers
Answer:
4782969
Step-by-step explanation:
Answer:
[tex]\sqrt[7]{3^{2}}[/tex]
Step-by-step explanation:
[tex]3^{2/7}[/tex]
^ That is 3 to the 2/7ths power. We know that. Now it needs to be in radical form. That takes a bit of thinking.
If you have a power that is less than one (like 1/2) it is can be written as a root. So say you're given [tex]2^{1/2}[/tex]. That is the same exact thing as saying [tex]\sqrt{2}[/tex]. It's the same thing. You can say it either way.
In the same way, a squared power, like [tex]2^{2}[/tex], is the same as representing it like a fraction, like [tex]2^{2/1}[/tex]. They both mean the same thing.
So by pointing these out, a fraction power = the power / the root.
If that makes sense.
So, with this in mind, let's look at what we have again.
[tex]3^{2/7}[/tex]
So we can split it up to say that 3 is raised to a 2nd power times a 1/7th power.
So we know what a 3 to the 2nd power is: [tex]3^{2}[/tex].
And since we have a fraction that's also included, we now know that is a root. So we can represent that like this: [tex]\sqrt[7]{3}[/tex].
But those two answers need to be combined. We can do that like this: [tex]\sqrt[7]{3^{2}}[/tex]
Answer: [tex]\sqrt[7]{3^{2}}[/tex]

To get the missing angle, add the 2 angles, 60 and 60.
60 + 60 = 120.
Then subtract from 180.
180 - 120 = 60.
Hence, 60 is the answer.

What is the approximate area of this figure?

Answers
Answer:
157 in²Step-by-step explanation:
The area of the shape is the sum of three sections
1. Rectangle
A = 5*14 = 70 in²2. Bigger semicircle
A = 1/2π(14/2)² = 76.96 ≈ 77 in² (rounded)3. Smaller semicircle
A = 1/2π(5/2)² = 9.8174 ≈ 10 in² (rounded)Total area:
70 + 77 + 10 = 157 in²answer:
157 inches²
step-by-step explanation:
we have to break this down into parts and find the area of each part and then add them up so we have the area for the whole thingrectangle:
5 X 14 = 70 inches²
big semicircle:
solve this like a simple circle and then divide by 2 since this is halfarea = πr²
insert what we know from the questionarea = (3.14)(7)²
the radius would be seven because as you can see the length of a side of the rectangle is 14 and this is also the diameter of the circle since they are attached and share itthe radius is half of the diameter so we get 7area = 3.14(49)
= 153.86 inches²
now divide this by 2 since it is semicircle153.86 / 2 = 76.93 inches²
small semicircle:
area = (3.14)(2.5)²
i followed the same method as last, except the numbers are differentarea = 3.14(6.25)
= 19.625 inches²
now divide by 219.625 / 2 = 9.8125 inches²
finally, add up all the separate areas you got70 inches² + 76.93 inches² + 9.8125 inches²
= 156.7425 inches²
= 157 inches²
2. Find the area of the regular polygon.
*HINT* - You must solve for the side of the octagon before you can find the area of the figure.
a. What is the Perimeter of the figure?
b. What is the area of the figure?
Answers
Answer:
a. 80 units
b. 482.843 units²
Step-by-step explanation:
First things first, we need to solve for the side of the octagon. We can do so by using Pythagorean Theorem: a² + b² = c² where c is the hypotenuse and a and b are the other two sides.
12² + b² = 13²
144 + b² = 169
b² = 25
b = 5
Now that we know half of the side of the octagon is 5, we know that one side of the octagon is 10.
a. To find perimeter we just add every side together (or since every side is the same size, we multiply by 8)
10 × 8 = 80
b. The formula for finding the area of an octagon is 2(1 + radical 2)a² where a is the length of a side. By plugging in to a calculator we get:
2(1 + radical 2)(10)² = 482.843
