The 5-foot pole casts a shadow of 3 feet. The building casts a shadow of 12 feet. What is the height of the building?
Answer:
20 ft
Step-by-step explanation:
Because your are scaling the shadow by 4, you have to scale the height by 4
Answer: 20 foot tall.
Step-by-step explanation: the shadow of the pole is 3 feet. and the shadow from the building is 12 feet.
12 can be divided by 3, 4 times. we know for every 3 foot shadow, the actual object is 5 feet tall.
we just multiply 5 by 4 to get 20.
we can also check our work by dividing 3 by 5. this is 0.6.
then we divide 12 by 20. that is also 0.6.
hence that is the answer.

Javier and his friends go out to eat. The restaurant they chose automatically adds a 15% gratuity to their food bill since they are a party of 12. The total bill after the automatic 15% gratuity was $213.90. Because they received such good service, the group decided to add an extra $20 to the total bill as an additional tip.
So, instead of leaving a 15% tip, Javier and his friends ended up leaving a tip that was about __% of the food bill.
Answer:
26% tip
Step-by-step explanation:
213.90 / 1.15 = 186
213.90 + 20 = 233.9
233.9 / 186 = 1.26
26% tip
What is the simplified version of Square root of 3÷512
Answer:
(1/32)√6
Step-by-step explanation:
Symbolically, this is
√(3/512) 3
which can be rewritten as √(-------------
2√256
The advantage of doing this is that 256 is a perfect square. We now have:
3 √3 √3√2 √6 √6
√(-----------) = ------------ = ------------ = ---------- = ----------
2(256) 16√2 16(√2)² 16(2) 32

Lin is shopping for a couch with her dad and hears him ask the salesperson, “How much is your commission?” The salesperson says that her commission is 512%512% of the selling price.
How much commission will the salesperson earn by selling a couch for $495? Round to the nearest cent
How much money will the store get from the sale of the couch
Answer:
$27.23
$467.77
Step-by-step explanation:
Commission of the salesperson = 5 1/2%
How much commission will the salesperson earn by selling a couch for $495? Round to the nearest cent
Salesperson commission = 5 1/2% of the price
= 5 1/2% × $495
= 11/2% × 495
= 0.055 × 495
= $27.225
Approximately,
$27.23
How much money will the store get from the sale of the couch
= Price - salesperson commission
= $495 - $27.23
= $467.77

An object is launched from a platform.
Its height (in meters), xxx seconds after the launch, is modeled by:
h(x)=-5x^2+20x+60h(x)=−5x
2
+20x+60h, left parenthesis, x, right parenthesis, equals, minus, 5, x, squared, plus, 20, x, plus, 60
How many seconds after launch will the object land on the ground?
Answer:
6seconds
Step-by-step explanation:
Given the height of an object modeled by the expression
h(x)=-5x^2+20x+60
The height of the object on the ground is zero i.e h(x) = 0
On substituting
h(x)=-5x^2+20x+60
0 =-5x^2+20x+60
Multiply through by -1
5x^2-20x- 60 = 0
Divide through by 5
x^2 - 4x - 12 = 0
x^2 - 6x + 2x - 12 = 0
x(x-6)+2(x-6) = 0
(x-6)(x+2) = 0
x - 6 = 0 and x+2 = 0
x = 6 and -2
Since time cannot be negative, hence it takes 6seconds after launch for the object land to on the ground

Find the value of x. Round to the nearest tenth. The diagram is not drawn to scale.
Answer:
Cosine 24 = adjacent / hypotenuse (x)
0.91355 = 11 / hypotenuse
hypotenuse = 11 / 0.91355
hypotenuse (x) = 12.0409391933
or x = 12.04 (rounded)
Step-by-step explanation:
If P and Q are two sets then n( P-Q) means ?
[tex]\huge{\mathbb{ \tt{ANSWER}}}[/tex]
I shall use the symbol U for union
^ for intersection
~ for complement
----------------------------------------------------------------------------------------------------
The property of set subtraction states that for any sets X and Y, X-Y = X ^ Y~
That is in words, X throw away Y is the same as the intersection of X and the complement of Y
or X and anything NOT in Y
At the SET level, the proof looks like this:
(P-Q) U (Q-P) = « given
(P^Q~) U (Q ^ P~) = « property of set subtraction
(P U Q) ^ (P U P~) ^ (Q~ U Q) ^ (Q~ U P~) = « distributive property
(P u Q) ^ (Q~ U P~) = « Union of any set with it's complement is the universal
set which gets dropped by any intersection of a non-universal set
(P u Q ) ^ (Q ^ P)~ = « De Morgan's Law
(P u Q) - (Q ^ P) = « property of set subtraction
(P u Q) - (P ^ Q) « commutative property
----------------------------------------------------------------------------------------------------At the ELEMENT level, the proof looks like this:
» Proves left side is subset of right side
If x is in (P-Q) U (Q-P) then x is in (P-Q) OR x is in (Q-P)
If x is in P-Q then x is in P but not in Q.
Then X is in P U Q.
Since x is not in Q, x is NOT in P ^ Q
Hence x is in P U Q but NOT in P^Q, which
means it is an element if (P U Q) - (P ^ Q)
Therefore x is an element of the set defined by the right side, which means (P-Q) U (Q-P) is a subset of (P U Q) - (P ^ Q)
« proves right side is subset of the left side
If x is an element of (P U Q) - (P ^ Q) then
x is in (P U Q) but NOT in (P^Q)
Since x is in P U Q, x is in P OR x is in Q.
Since x is NOT in (P^Q) then x is NOT in BOTH P and Q.
Hence x is in either P or Q but not both.
If x is in P, then x is not in Q, so x is in P-Q.
Therefore x is in (P-Q) U (Q-P).if x is in Q, then x is not in P, so x is in Q-P.Therefore x is in (Q-P) U (P-Q).There x is an element of set defined by the left side, which menas (P u Q)-(P ^Q) is a subset of (P-Q) U (Q-P).

What is the area of kite QRST? If necessary, round to the nearest tenth.
Answer:
Area of kite = 17 feet²
Step-by-step explanation:
Given:
For big triangle;
Length of base = 5.2 feet
Length of height = 2.5 feet
For small triangle;
Length of base = 1.6 feet
Length of height = 2.5 feet
Find:
Area of kite
Computation:
Area of kite = 2[Area of big tringle] + 2[Area of small triangle]
Area of kite = 2[(1/2)(b)(h)] + 2[(1/2)(B)(H)]
Area of kite = [(5.2)(2.5)] + [(1.6)(2.5)]
Area of kite = 13 + 4
Area of kite = 17 feet²
