A 5.5 foot tall woman is standing 14 feet from a streetlamp casts a six foot shadow. How high is the lamp?
Answer:
The height of the lamp is 18.33 ft
Step-by-step explanation:
We can think in two triangle rectangles, one with cathetus of:
5.5ft and 6ft (the one formed by the woman ad her shadow)
And another triangle with cathetus equal to:
6ft + 14ft (the distance between the end of the shadow and the lamp)
And the other cathetus is the height of the lamp, H.
As bot triangles will share an angle (the one formed by the end of the shadow and the hypotenuse) then the triangles are equivalent, so the quotient between their cathetus will be equal, this is:
H/(6ft + 14ft) = 5.5ft/6ft
H/(20ft) = 5.5ft/6ft.
H = (5.5ft/6ft)*20ft = 18.33 ft

999x645 using distributive property
Answer:1. distributive property
2. commutative property (the order of 8x and -24 is swapped)
3. reflexive property ((8-24) = -16; -16 is substituted for 8-24. I prefer "substitution property".)
4. commutative property (the order of 8x and -16 is swapped)
5. distributive property

Brainliest is gained through the correct answer, that's explained. At 86 km/h, how far can you travel in 8 h? Use unit analysis to check your answer.
Glad I can help!!!
Answer:
688
Step-by-step explanation:
Assuming that the car stays at exactly the same speed for all 8 hours then the equation you should use is 86 x 8=688.
If satisfied leave a review to let me know how I did and feel free to give brainiest.
Answer:
688 kilometers.
Step-by-step explanation:
im not sure what unit analysis is, but you would multiply 8 and 86. kilometer per hour. soo yeah lol 8×86=688. you would be able to travel 688 kilometers. you Don't have to give me brainliest lol but I hope that this helps :)
What is the area of the triangle?
(-6,3)
(-3,-5)
(-1,3)
Hey there! I'm happy to help!
To find the area of a triangle you multiply the base by the height.
We see that our base is 5 units long because it stretches from -6 to -1 on the coordinate plane. Our height is 8 because the y value goes from 3 to -5.
To find the area of a triangle, you just multiply the base by the height then divide by 2.
5(8)=40
40/2=20
The area is 20 square units.

Answer:
B) $3.56
Step-by-step explanation:
The price of one egg: $1.69
The price of a slice of bacon: $1.49
The price of a glass of orange juice: $1.09
Sara buys 2 eggs, 1 slice of bacon, and 1 glass of orange juice.
(2 eggs x $1.69) + (1 bacon x $1.49) + (1 glass of oj x $1.09) =
($3.38) + ($1.49) + ($1.09) = $5.96
Next, add the total gotten with the sales tax.
Sales tax: $0.48
$5.96 + 0.48 = $6.44
Then, subtract the total from the $10 that she used to pay:
$10 - 6.44 = $3.56
B) $3.56 is your answer.
~
Answer:
3.56
Step-by-step explanation:
because first, you 1.69$ dollars 2 times since your ordering it 2 times which gets you 3.38 $ next you add 1.49$ dollars because that's what a slice of bacon cost, then add1.09 since that's what a cup of orange juice cost. Then add 0.48 cents because that's the sale tax, at the end when you add everything up you get 6.44$ then subtract that from 10.00, then you get your answer!

Answer:
1 and 3 are irrational!!! The others are all rational
Step-by-step explanation:
1 and 3 are never terminating and they are not repeating, therefore, they are irrational! All the others are either terminal (they have a decimal that stops) or they are repeting and those repeting numbers can be written as a fraction, for example 0.2222... can be written as 2/9

How many ways can 6 people be chosen and arranged in straight line if there are 8 people to choose from? a. 48.b. 720.c. 20, 160.d. 40, 320.
Answer:
C. 20,160Step-by-step explanation:
This question bothers on permutation since we are to select a some people out of a group of people and then arrange in a straight line. If r object are to be arranged in a straight line when selecting them from n pool of objects. This can be done in nPr number of ways.
nPr = n!/(n-r)!
Selection of 6 people out of 8 people can therefore be done in 8C6 number of ways.
8P6 = 8!/(8-6)!
8P6 = 8!/2!
8P6 = 8*7*6*5*4*3*2!/2!
8P6 = 8*7*6*5*4*3
8P6 = 56*360
8P6 = 20,160
Hence this can be done in 20,160 number of ways
Y is the midpoint of XZ. X has coordinates (2, 8), and Y has coordinates (–3, 10). Find the coordinates of Z.
Answer:
The coordinates of Z is (-8,12)
Step-by-step explanation:[tex]\frac{2+x^{2} }{2}= -3 \\\frac{8+y^{2} }{2} = 10[/tex]
You multiply -3 by 2 to get -6 then multiply 10 by 2 to get 20
then you create the equations [tex]2+x^{2} =-6\\8+y^{2} =20[/tex] you subtract 2 by -6 and you get -8 (x coordinate) and you subtract 8 by 20 to get 12 (y coordinate)
To check your answer you use the Midpoint formula [tex](\frac{x^{1}+ x^{2} }{2} )(\frac{y^{1}+y^{2}}{2}) =M[/tex]
[tex]\frac{2+-8}{2} =\frac{-6}{2} = -3\\\frac{8+12}{2} =\frac{20}{2} =10[/tex] and you get your midpoint.
