Answer:
16.2
Step-by-step explanation:
Use the law of cos
c^2 = 8^2+10.4^2-2*8*10.4*cos(122.2 degrees)
=260.83
c = √260.83 = 16.15
The missing side of the triangle is 16.2 km (round to the nearest tenth)
What is law of cosines ?
If a, b, c are sides of a triangle & C be the angle opposite to side c, then
c²=a²+b²-2ab cosC
What is the missing side ?Here, in the given question, a = 8km & b = 10.4 km
Also the angle opposite to the third side c (say) is C = 122.2°
So, according to the law of cosines,
c²=(8)²+(10.4)²-2(8)(10.4) cos(122.2°)
⇒ c²= 64+108.16-(-88.67)
⇒ c²= 172.16+88.67
⇒ c²= 260.83
⇒ c= √(260.83)
⇒ c= 16.15 = 16.2(approx)
So, the missing side = 16.2 km

Pls Help! This is due today! Find the value of x:
Answer:
x = 23
Step-by-step explanation:
the sum of all interior angles of triangle is 180 dehrees.
top angle = 180-100 = 80 degrees
80 + 51 + (2x+3) = 180
2x+3 = 49
2x = 46
x = 23
Banu will build a fence around a rectangular
30-foot-by-25-foot play area. Given that fencing costs
$4.05 per foot, how much will the fencing cost for
Banu to completely surround the play area?
Answer:
A
Step-by-step explanation:
Dimension of the rectangular fence:
Length = 30 ft
Width = 25 ft
Perimeter of the rectangular fence = 2(L + W)
= 2(30 + 25) = 2(55)
Perimeter = 110 ft
Fencing cost per foot = $4.05
Fencing cost for 110 ft = 110 × 4.05 = $445.50

Which value in the set [4, 9, 15, 36] is a solution of 12 = 3 + x?
Answer:
x=9
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
12=x+3
Step 2: Flip the equation.
x+3=12
Step 3: Subtract 3 from both sides.
x+3−3=12−3

QRS~TUV. what is the measure of V?
Answer:
70°
Step-by-step explanation:
As we can see that that triangles are similar so
angles are equal
< U = 47° and < T = 63°
So now
< U +< T + <V = 180°< being sum of angles of triangle >
47° + 63° + < V = 180°
< V = 180° - 110°
< V = 70°
Hope it will help :)❤
Answer:
70 degrees
Step-by-step explanation:
Similar triangles are different in size, but same in angles. That means...
Angle R is congruent to Angle U, Angle Q is congruent to Angle T.
By the Triangle Sum Theorem, all triangles add to 180 degrees.
Angle U + Angle T + Angle V = 180 degrees
47 + 63 + Angle V = 180
Angle V = 70

Determining a Better Choice
Last year, Ron had made an 18% percent error when he
bought 168 notebooks and customers needed 200. This
year, he made a 24% error when he bought 310
notebooks and sold only 250. Compare the percent errors
for the two years and determine which year Ron made a
better estimate.
I
Answer:
Last year the percent of error was lower than this year. The smaller the percent of error, the closer the estimate is to the exact value. Last year, Ron made a better estimate.
Use a table of Laplace transforms to find the Inverse Laplace transform of
F(s)= [tex]\frac{3s+9}{s^2+9}[/tex]
f(t)=_____
Answer:
The inverse Laplace transform of [tex]F(s) = \frac{3\cdot s + 9}{s^{2}+9}[/tex] is [tex]f(t) = 3\cdot \cos \omega t + 3\cdot \sin \omega t[/tex].
Step-by-step explanation:
In this case, we should use the following direct and inverse Laplace Transforms:
[tex]F(s) = G(s) + H(s)[/tex] (1)
[tex]\mathcal{L}^{-1} \{\frac{s}{s^{2}+\omega^{2}} \} = \cos \omega t[/tex] (2)
[tex]\mathcal{L}^{-1}\{\frac{\omega}{s^{2}+\omega^{2}} \} = \sin \omega t[/tex] (3)
[tex]\mathcal\{L\}^{-1}\{c\cdot F(s)\} = c\cdot \mathcal\{L\}^{-1}\{F(s)\}[/tex] (4)
Then, we apply all these trasforms:
[tex]F(s) = \frac{3\cdot s + 9}{s^{2}+9}[/tex]
[tex]F(s) = 3\cdot \left(\frac{s}{s^{2}+9} \right)+3\cdot \left(\frac{3}{s^{2}+9} \right)[/tex]
[tex]f(t) = 3\cdot \cos \omega t + 3\cdot \sin \omega t[/tex]
The inverse Laplace transform of [tex]F(s) = \frac{3\cdot s + 9}{s^{2}+9}[/tex] is [tex]f(t) = 3\cdot \cos \omega t + 3\cdot \sin \omega t[/tex].

Answer:
p=10
Step-by-step explanation:
3p+10+5p=90
8p+10=90
8p=80
p=10
Answer:
p = 5
Step-by-step explanation:
Th angles are complimentary, meaning that they equal 90° if put together. This mean that you can set them equal to eachother.
3p + 10 = 5p
Subtract 3p from both sides.
10 = 2p
Divide both sides by 2.
p = 5
You can check you work by plugging in 5 for p.
3(5) + 10 = 5(5)
15 + 10 = 25
25 = 25
Therefore, p = 5.

Answer:
A)12Step-by-step explanation:
to understand thisyou need to know about:equationPEMDASlet's solve:according to the question
[tex] \sf \: 2x + 4 + 62 = 90[/tex]
simplify addition:
[tex] \implies \sf 2x + 66 = 90[/tex]
subtract 66 from both sides:
[tex] \sf\implies 2x + 66 - 66 = 90 - 66 \\ \sf\implies2x = 24[/tex]
divide both sides by 2:
[tex] \sf \implies \: \frac{2x}{2} = \frac{24}{2} \\ \sf \therefore \: x = 12[/tex]
Answer:
Solution given:
62°+2x+4+90=180°[ sum of interior angle of a triangle is 180°]
2x=180-156°

what does l-7l mean and whats its value NEED HELP
A
9x - 40
B
3x + 20
x = [?]
Answer:
x = 10
Step-by-step explanation:
9x - 40 = 3x + 20
9x - 3x - 40 = 3x - 3x + 20
6x - 40 = 20
6x - 40 + 40 = 20 + 40
6x = 60
6x / 6 = 60 / 6
x = 10
Now plug the x value in the equation to make the statement true that A is parallel to B.
9x - 40
9(10) - 40
90 - 40
50
3x + 20
3(10) + 20
30 + 20
50
Therefore, x = 10 making the statement true that A is parallel to B. Hope this helps and stay safe, happy, and healthy, thank you :) !!

Answer:
y/9
g - 5
(6 * w) - 4
7 + (3g)
64/f
Step-by-step explanation:
For these questions, make sure to follow the order shown.
1. quotient is the answer of a division question, so it would be y/9
2. Difference is the answer of a subtraction question, so it would be g - 5
3. Product is the answer of a multiplication question, so it would be (6 * w) - 4
4. Remember, follow the order. The variable 'd' represents your dog's weight, so it would be 7 + (3g)
5. Remember when you are trying to find individual costs from a group payment, you have to divide the total by how many people there are. So, the variable 'f' represents how many friends were in the group, so it would be 64/f
Hope this helps :)
Answer:
1) [tex]\frac{y}{9}[/tex]
2) 2g - 5
3) 6w - 4
4) let d = dog's weight and m = my weight
