Answer:

a) 7 kmb) 298°

Step-by-step explanation:

See attached diagram (not to scale).

All given details reflected.

a) Find the measure of XZ using the law of cosines:

y = √(5² + 3² - 2*5*3*cos 135°) = 7 km (rounded)

b) Now using the law of sines find the measure of angle X:

7 / sin 135° = 5 / sin X sin X = 5 sin 135° / 7m∠X = arcsin (5 sin 135° / 7 ) = 28° (rounded)

The bearing of Z from X is:

270° + 28° = 298°

Answers

Answer:

JM = 20

Step-by-step explanation:

Find the value of JM

Using similar triangles;

MJ/HN = GJ/HK

GJ+JM/HN = GJ/HK

15+JM/12+16 = 15/12

15+JM/28 = 15/12

Cross multiply

12(15+JM) = 15*28

180+12JM = 420

12JM = 420 - 180

12JM = 240

JM = 240/12

JM = 20

Hence the length of JM is 20

The area of a rectangular parking lot is 8051 m ^2 . If the length of the parking lot is 97 m, what is its width?

Answers

Answer:

Width of rectangle = 83 meter

Step-by-step explanation:

Given:

Area of rectangle = 8,051 m²

Length of rectangle = 97 m

Find:

Width of rectangle

Computation:

Area of rectangle = Length of rectangle x Width of rectangle

97 x Width of rectangle = 8,051

Width of rectangle = 8,051 / 97

Width of rectangle = 83 meter

V= u +at U=2 A=-5 T=1/2 Work out the value of v

Answers

Answer:

Step-by-step explanation:

v =u+at

v=2 -5/2

v=4-5/2

v=-1/2/2

Answer:

Step-by-step explanation:

Given

u = 2 , a = - 5 t = 1/2

Now

v = u + at

= 2 + (-5) * 1/2

= ( 4 - 5) /2

= - 1/2

Rename 5/6 and 14/15 using the least common denominator.

Answers

Answer:

25/30 and 28/30

Step-by-step explanation:

1. To find the least common denominator, you need to find the least common multiple of the two denominators which are 6 and 15. Prime factorization of these numbers gives:

6 = 2 x 3

15 = 5 x 3

A number that would evenly divide both 6 and 15 must contain 2 x 3 x 5 which is 30.

Thus 30 is the least common denominator.

2. Now we need to somehow change both fractions to make them have a denominator of 30. To do this we can multiply by fractions with same numerator and denominator since that would be like multiplying by 1.

So, 5/6 x 5/5 = 25/30

And 14/15 x 2/2 = 28/30

25/30 and 28/30

Given that
[tex]2 {}^{x} = 0.125[/tex]
Find x

Answers

Take the natural log of both sides

ln(2^x)=ln(.125)
Xln(2)=ln(.125)
X=ln(.125)/ln(2)
X=-3

ALTERNATIVE ROUTE:
You know that 0.125 is equal to 1/8
And 1/2^3 is also equal to 1/8
So since you need the reciprocal to match it the exponent is a negative

Answer:

x = -3.

Step-by-step explanation:

2^x = 0.125

Taking logs:

x ln 2 = ln 0.125

x = ln 0.125 / ln 2

x = -3

Write an equation for the hanger diagram and then us the sketch to show how to solve the equation algebraically.

Answers

Step-by-step explanation:

Since there are 3 w's and a 1 on one side and 7 1's on the other and the hanger diagram shows they are even, we can set them equal to each other.

3w + 1 = 7 Subtract 1 from both sides

3w = 6 Divide 3 from both sides

w = 2

Someone read this and just tell me in short words about what is says.Art can be made out of anything, including ordinary things we find around us.Everyday objects that we usually throw away, such as metal cans or bits ofnewspaper, can be reused to make sculpture, jewelry, or musical instruments, forexample. Their value depends on the artists ability to see how their shape, color,material, or design can be used in a new way. Some artists even recycle images andmaterials from other peoples art, adding personal touches or altering the originalartwork to make their own statement.A patchwork quilt is sewn together from scraps, remnants, and rags. Quilters,often working together, combine these irregular bits and pieces of cloth into a newpattern. In rural America, the traditional quilting bee gave friends and neighbors achance to get together and exchange news and gossip.Public places can become art spaces. Artists on New Yorks Lower East Sidehave transformed an old gas station into a gallery, sculpture garden, and performancespace. They turn abandoned cars and other urban debris into a community work ofart that continues to grow. . . .The German artist Kurt Schwitters (18871948) used discarded objects to createa style of art he called Rubbish. Schwitters walked the streets collecting torn piecesof paper, ticket stubs, and bits of stringanything someone had thrown awayandused glue to combine them on a plain background. That kind of picture is called acollage, from the French word for paste. . . .With a little imagination, any object can be used for art. During World War II, rawmaterials of all kinds were in short supply. The famous Spanish artist Pablo Picasso(18811973) hoarded junk such as bicycle frames, mattress springs, and gardeningtools, which he made into sculptures. Bulls Head, created in 1942, is made from abicycle seat and handlebars cast in bronze.Musical instruments can be made from recyclables. American composer HarryPartch (19011974) turned large glass bottles called carboys into an enormous setof hanging gongs. Partch named his instrument the Cloud-Chamber Bowls in 1950,when he found the tops and bottoms of carboys that had been cut in a laboratory . . . .Doing some experimenting of his own, he discovered ways of striking the bowls toproduce beautiful and complex tones.Have you ever stacked stones in a huge pile or built a fort out of sticks? Thenyoure an Earth Artist. You dont need paint or paper to make art: in fact, Earth ArtistAndy Goldsworthy started out with a simple rule: he would work outside and only usematerials he could find nearby. That meant using thorns to pin dried stalks togetherand spit to paste leaves to rocks! I splashed in water, covered myself in mud, wentbarefoot, and woke with the dawn, Goldsworthy says in the book Hand to Earth. Healso got rained and snowed on a lot, sometimes on purpose! To make a rain shadow,Goldsworthy lies down on the ground when its just beginning to rain, then gets uponce hes soaked and takes a picture of the man-shaped dry spot he left behind.Home is in Scotland, but Goldsworthy has worked in the United States, France,Australia, Japan, and even at the North Pole. His finished works made of stones,sticks, leaves, ice, sand, or mud look astoundingly simple and beautiful, but theprocess can be filthy and even frustrating. The purpose isnt just to make a nice pieceof artits a way of learning about the world. In his book A Collaboration with Nature,Goldsworthy says, I stop at a place or pick up a material because I feel there issomething to be discovered. Here is where I can learn.Gluing IciclesA man with white hair, a white beard, and a Scottish accent rubs his freezinghands together before picking up a piece of icicle, dipping it in snow and then inwater, and holding it against another bit of ice. Then he waits patiently until the twopieces freeze together.Andy Goldsworthy is being filmed in action for the documentary Rivers and Tides.The curving line of ice hes working on looks as if it weaves through and around apoint of stone. If a piece of icicle doesnt fit quite right, he chews the end until it does.His hands are cold and dirty, but he cant feel the ice properly with gloves on. Itshard going and its hard on the hands. . . . All effort is going into trying to makesomething that is effortless, he says.Finally, the Sun rises and shines through the curving ice; it seems to glow. I neverhad any idea that would happen! Goldsworthy says with delight, going on to pointout that the very thing that brings the work to life is the thing that will cause itsdeath. The ice will melt in the sunlight, and the sculpture will be gone.Balancing Stones What is 0.5 (0.1)(1/2) The area of a rectangular parking lot is 8051 m ^2 .
