I think this is the correct answer. Thanks
Answer:
Answer is -32.
Step-by-step explanation:
a= -2
b=7
Expression: a(b2-a)
-2(7*2--2) (Place 'a' and 'b' values)
= -2(14+2) (Solve inside the bracket)
= -28-4 (Multiply -2 with the values inside the bracket)
= -32 (ans)

WRITE THE RATIO: A cookie recipe calls for 1 cup of flour to make 24 cookies. Create a proportion to show how many cups of flour are needed to make 36 cookies
Answer:
1&(1/2) or 1.5 or 3/2 cups flour needed for 36 cookies
Step-by-step explanation:
Flour : Cookie ratio (Flour needed to make particular cookie) = 1 : 24
1 cup flour make 24 cookies, so 1/2 cup floor make 12 (half) cookies.
So, 1&(1/2) or 1.5 or 3/2 cups would make 24 + 12, ie = 36 cookies
AlternativelyMultiplying numerator & denominator of fractional ratio 1 : 24 with 1.5 each
(1 x 1.5) : (24 x 1.5)
It implies 1.5 : 36 flour cookie ratio
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 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 rectangle has vertices A(0, 0), B(0, 9), C(4, 9), and D(4, 0). What is the perimeter of the rectangle
Answer:
26 units
Step-by-step explanation:
A rectangle has vertices A(0, 0), B(0, 9), C(4, 9), and D(4, 0). What is the perimeter of the rectangle
We have to find the length of the sides of the rectangle using the formula below
= √(x2 - x1)² + (y2 - y1)² when given vertices (x1, y1) and (x2, y2)
For side AB
A(0, 0), B(0, 9)
= √(0 - 0)² + (9 - 0)²
= √0 + 81
= √81
= 9 units
For side BC
B(0, 9), C(4, 9)
= √(4 - 0)² + (9 - 9)²
= √4² + 0²
= √16
= 4 units
For side CD
C(4, 9), and D(4, 0)
= √(4 - 4)² + (9 - 0)²
= √0² + 9²
= √81
= 9 units
For side AD
A(0, 0), D(4, 0).
= √(4 - 0)² + (0 - 0)²
= √4² + 0
= √16
= 4 units
We can see than
AB = CD = 9 units
BC = AD = 4 units
The perimeter of a rectangle = 2(L + W)
From the above calculation
Length = 4 units
Width = 9 units
Perimeter = 2(4 + 9) units
= 2 × 13 units
= 26 units
Carol's car average is 17.1 miles per gallon in City driving and 24.7 miles per gallon in highway driving if she drove a total of 513.0 miles on 26 gallons of gas how many of the gallons were used for City driving
Answer:
the volume of the gas used for city driving is 17 gallons
Step-by-step explanation:
Given;
average speed for city driving, v₁ = 17.1 miles per gallon
average speed for highway driving, v₂ = 24.7 miles per gallon
total distance traveled, d = 513 miles
total gallon of gas used, t = 26 gallons
Let the volume of gas used for city driving = x
Also, let the volume used for highway driving = y
x + y = 26 -------- (1)
17.1x + 24.7y = 513 ------------(2)
From equation (1); y = 26 - x
Substitute the value of y in equation (2)
17.1x + 24.7(26-x) = 513
17.1x + 642.2 - 24.7x = 513
17.1x - 24.7x = 513 - 642.2
-7.6x = -129.2
x = 129.2/7.6
x = 17 gallons
Therefore, the volume of the gas used for city driving is 17 gallons

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
