22.44 mi²Step-by-step explanation:
Step 1
Find the missing angle:
m∠H = 180° - (47° + 99°) = 34°Step 2
Find the missing sides by using the law of sines:
sin 34° / 5.9 = sin 47° / HP = sin 99° / HKHP = 5.9 sin 47°/sin 34° = 7.7 miHK = 5.9 sin 99° / sin 34° = 10.4 miStep 3
Use Heron's formula for the area:
A = [tex]\sqrt{s(s - a)(s - b)(s - c)}[/tex], where s is semi-perimeter, and a, b, c - sidesFind s:
s = 1/2(5.9 + 7.7 + 10.4) = 12Find A:
A = [tex]\sqrt{12(12 - 5.9)(12 - 7.7)( 12 - 10.4)}[/tex] = 22.44 mi²Related Questions
determine the value of k if g(x)=4x-k is a tanget to f(x)=-x²+8x+20
Answers
Answer:
This seems to be incomplete because we do not know where g(x) must be tangent to f(x). So i will assume that we want g(x) to be a tangent to f(x) in the point x0.
We know that for a function f(x), f'(x) is the tangent function in at the point x.
Where f'(x) = df(x)/dx
So we can find a value of k that is equal (for some value of x) to the first derivative of f(x).
g(x) = 4*x - k
f(x) = -x^2 + 8*x + 20
f'(x) = -2*x + 8
Now we want to find a value of k such that:
4*x0 - k = -2*x0 + 8
4*x0 - k = -2*x0 + 8
4*x0 + 2*x0 - 8 = k
6*x0 - 8 = k
Then if we want g(x) to be a tangent to f(x) = -x²+8x+20 in the point x0, we must have k = 6*x0 - 8

mZAOC is a straight angle.
MZAOB = 8x + 51°
mZBOC = 6x - 25°
Find mZAOB=
Answers
Answer:
∠ AOB = 139°
Step-by-step explanation:
Since AOC is a straight line then
∠ AOB + ∠BOC = 180° , that is
8x + 51 + 6x - 25 = 180
14x + 26 = 180 ( subtract 26 from both sides )
14x = 154 ( divide both sides by 14 )
x = 11
Then
∠ AOB = 8x + 51 = 8(11) + 51 = 88 + 51 = 139°
The distance between Rosa's house and her school is 4 1/2 of a mile. She ran 3 mile. What fraction of the distance between her house and her school, did Rosa run?
Answers
Answer:
Rosa ran [tex]\frac{2}{3}[/tex] of the total distance between her house and her school.
Step-by-step explanation:
Distance between Rosa's house and her school = [tex]4\frac{1}{2}[/tex] miles ≈ 4.5 miles
She ran distance = 3 miles
Therefore, fraction of the total distance between her house and school she run = [tex]\frac{\text{Distance run by Rosa}}{\text{Total distance between her house and school}}[/tex]
= [tex]\frac{3}{4.5}[/tex]
= [tex]\frac{30}{45}[/tex]
= [tex]\frac{2}{3}[/tex]
Therefore, Rosa ran [tex]\frac{2}{3}[/tex] of the total distance between her house and her school.
Solve this equation: −10x−10=−10x−10
Answers
Answer:
0
Step-by-step explanation:
The whole thing cancels out because if you move -10x on the left to the right they will cancel out because -10x+10x=0.
Now, you have -10=-10 and so move the -10 to the right and it becomes positive so you get -10+10 which equals 0.
A rectangular floor is 5yd long and 4yd wide. Amy wants to tile the floor with tile sold by the square foot. Use the facts to find the area in square feet.
Answers
Answer:
Step-by-step explanation:
5yd(4yd)(9ft^2/yd^2)=180ft^2
The area of the rectangular floor is 180 square feet.
To find the area of the rectangular floor in square feet, we need to convert the dimensions from yards to feet and then multiply them.
Length of the floor = 5 yards
Width of the floor = 4 yards
To convert yards to feet, we know that 1 yard is equal to 3 feet.
Converting the length and width from yards to feet:
Length of the floor in feet = 5 yards * 3 feet/yard = 15 feet
Width of the floor in feet = 4 yards * 3 feet/yard = 12 feet
Now, we can calculate the area of the floor in square feet by multiplying the length and width:
Area of the floor = Length * Width = 15 feet * 12 feet = 180 square feet
Therefore, the area of the rectangular floor is 180 square feet.

1. Let x= -2 and y= -5. (NC.7.NS.2) Which expression has a negative value? A. X+y B.X-y C.[x] [y] D. X/y
Answers
Answer:
A. X + Y
Step-by-step explanation:
From this question x = -2 and y = -5
We are to find out the expression that would give a negative value.
X+Y
(-2)+(-5)
+(-) gives a negative sign. So we have
= -2-5
= -7
For x - y
(-2) - (-5)
-(-) = positive
= -2 + 5
= 3.
For [x][y]
= (-2) x (-5)
= 10
since a negative sign multiplied with another negative sign gives a positive result
For X/Y
= -2/-5
= 2/5 the result here is positive because 2 negative signs when divided cancel out.
Therefore the answer is option A since it's result is negative. Others are positive

Read John Muir's "Calypso Borealis" and answer the question. [1] After earning a few dollars working on my brother-in law's farm near Portage [Wisconsin], I set off on the first of my long lonely excursions, botanising in glorious freedom around the Great Lakes and wandering through innumerable tamarac and arbor-vitae swamps, and forests of maple, basswood, ash, elm, balsam, fir, pine, spruce, hemlock, rejoicing in their bound wealth and strength and beauty, climbing the trees, revelling in their flowers and fruit like bees in beds of goldenrods, glorying in the fresh cool beauty and charm of the bog and meadow heathworts, grasses, carices, ferns, mosses, liverworts displayed in boundless profusion. [2] The rarest and most beautiful of the flowering plants I discovered on this first grand excursion was Calypso borealis (the Hider of the North). I had been fording streams more and more difficult to cross and wading bogs and swamps that seemed more and more extensive and more difficult to force one's way through. Entering one of these great tamarac and arbor-vitae swamps one morning, holding a general though very crooked course by compass, struggling through tangled drooping branches and over and under broad heaps of fallen trees, I began to fear that I would not be able to reach dry ground before dark, and therefore would have to pass the night in the swamp and began, faint and hungry, to plan a nest of branches on one of the largest trees or windfalls like a monkey's nest, or eagle's, or Indian's in the flooded forests of the Orinoco described by Humboldt. [3] But when the sun was getting low and everything seemed most bewildering and discouraging, I found beautiful Calypso on the mossy bank of a stream, growing not in the ground but on a bed of yellow mosses in which its small white bulb had found a soft nest and from which its one leaf and one flower sprung. The flower was white and made the impression of the utmost simple purity like a snowflower. No other bloom was near it, for the bog a short distance below the surface was still frozen, and the water was ice cold. It seemed the most spiritual of all the flower people I had ever met. I sat down beside it and fairly cried for joy.
[4] It seems wonderful that so frail and lovely a plant has such power over human hearts. This Calypso meeting happened some forty-five years ago, and it was more memorable and impressive than any of my meetings with human beings excepting, perhaps, Emerson and one or two others. When I was leaving the University, Professor J.D. Butler said, "John, I would like to know what becomes of you, and I wish you would write me, say once a year, so I may keep you in sight." I wrote to the Professor, telling him about this meeting with Calypso, and he sent the letter to an Eastern newspaper [The Boston Recorder] with some comments of his own. These, as far as I know, were the first of my words that appeared in print.
[5] How long I sat beside Calypso I don't know. Hunger and weariness vanished, and only after the sun was low in the west I splashed on through the swamp, strong and exhilarated as if never more to feel any mortal care. At length I saw maple woods on a hill and found a log house. I was gladly received. "Where ha ye come fra? The swamp, that awfu' swamp. What were ye doin' there?" etc. "Mony a puir body has been lost in that muckle, cauld, dreary bog and never been found." When I told her I had entered it in search of plants and had been in it all day, she wondered how plants could draw me to these awful places, and said, "It's god's mercy ye ever got out."
[6] Oftentimes I had to sleep without blankets, and sometimes without supper, but usually I had no great difficulty in finding a loaf of bread here and there at the houses of the farmer settlers in the widely scattered clearings. With one of these large backwoods loaves I was able to wander many a long wild fertile mile in the forests and bogs, free as the winds, gathering plants, and glorying in God's abounding inexhaustible spiritual beauty bread. Storms, thunderclouds, winds in the woods—were welcomed as friends.

yooo pls help fr.. whats the total surface area :( ive srsly been doing this for five hrs
Answers
Answer and Step-by-step explanation:
All you have to do is find the area of one of the half triangles, multiply that by 2, then multiply it by 4. Then find the area of the square.
Half of 8 is 4, which is the length of the small line of the triangle.
The area of a triangle equation is A = [tex]\frac{bh}{2}[/tex].
The area of a square equation is A = LW
Triangle:
[tex]A = \frac{10*4}{2}\\\\\\\\A = \frac{40}{2}\\\\\\A = 20[/tex]
The small triangle area is 20, so one triangle face of the square pyramid is 40.
40 times 4 is 160.
Square:
8 × 8 = 64
The area of the square is 64.
Now add together the areas.
Surface area:
160 + 64 = 224
The surface area of the square pyramid is 224 [tex]cm^{2}[/tex].
