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

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).

»X x K i m 0 2 x XA table with an area of 2688 inches and a length of 64''. Find the perimeter of the table
Answer:
212
Step-by-step explanation:
First you would need to divide 2688 and 64 you would get 42. Then, now you need to add 64+64+42+42. Which in the end equals 212.

Abbie opened a no-interest bank account with $20, and she deposits $14.50 every week. Carlos opened a no-interest bank account with $28, and he deposits $12.50 every week. Carlos and Abbie do not make any withdrawals from their accounts. The equation below can be used to find w, the number of weeks it will take for the balances in their accounts to be the same. 20 + 14.50w = 28 + 12.50w What value of w makes this equation true?
Answer:
4 weeks
Step-by-step explanation:
14.50 (4) + 20= 78
12.50 (4) + 28= 78
x-2y=4 in slope intercept form
Answer:
y = 1/2x - 2
Step-by-step explanation:
Slope intercept form:
y = mx + b
x - 2y = 4
-2y = -x + 4
2y = x - 4
y = 1/2x - 2

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.

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

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

If you rolled a six-sided die and rolled it 30 times you would have expected an 6 about 5 times so your answer would be B.
Which expression can be used to represent the 9 more than the quotient of 14 and 2? (14 + 2) ÷ 9 14 ÷ 2 X 9 (14 X 2) + 9 (14 ÷ 2) + 9
Answer:
The expression that can be used to represent 9 more than the quotient of 14 and 2 is (14 ÷ 2) +9
Step-by-step explanation:
The statement 9 more than the quotient of 14 and 2 means
9 + the quotient of 14 and 2.
Now, for the quotient of 14 and 2
Recall that,
Dividend ÷ Divisor = Quotient.
Here, Dividend = 14 and the Divisor is 2
Hence, the quotient of 14 and 2 can be represented by 14 ÷ 2
∴ The statement 9 more than the quotient of 14 and 2 becomes
9 + (14 ÷ 2) OR (14 ÷ 2) +9
Hence, the expression that can be used to represent 9 more than the quotient of 14 and 2 is (14 ÷ 2) +9
