Answer:
A
Step-by-step explanation:
The parentheses are switched around, making the answer still the same. However, for Answer choice C, it is Commutative Property because the factors are switched around.
=====================================================
Explanation:
The equation shown for choice A is in the form p*(q*r) = (p*q)*r which is the general format for the associative property of multiplication.
In this case, p = 2.5, q = 1/5 and r = 2/3.
The order of p,q,r stays the same while the parenthesis shift around. The stuff in the parenthesis is done first before anything else. Though with multiplication, the order doesn't matter which is why we can freely shift the parenthesis like this.
Addition has a similar rule which says p+(q+r) = (p+q)+r.

Throughout Lewis Carroll's book, Alice's Adventures in Wonderland, Alice's size changes. Her normal height is about 50 inches tall. She comes across a door, about 15 inches high, that leads to a garden. After drinking a potion, Alice's height changes to 10 inches so she can visit the garden. How tall would the door have been in Alice's normal world? Justify your answer and provide mathematical evidence.
Answers
Answer:
The answer is 75 inches.
Step-by-step explanation:
If Alice is 10 inches, she is 2/3 as tall as the door. At her regular height, to be 2/3 as tall as the door the door would have to be 75 inches high.
Raju’s age (in years) is 2 more than 5 times her daughter’s age. What is his age. guys help me
Answers
Step-by-step explanation:
if you are writing it in an expression then
let raju's age be = x
let daughter be = y
x = 2 (5 × y)
x = 2 (5y)
x = 10y
so if daughter is 2 years old, then
x = 10(2)
x = 20 years
Given the parent function p(x) = cos x, which
phrase best describes the transformation used
to obtain the graph of g(x) = cos (x + a) – b,
if a and b are positive constants?
Answers
Answer: left a units, down b units
Step-by-step explanation:
The phrase which describe g(x) for parents function p(x) is:
" Graph shifts a units in negative x direction and b units in negative y direction"
What is Shifting of Origin?The shifted origin has the coordinates (h, k). That is, the shifted X and Y axes are at distances h and k from the original X and Y axes respectively.
Here, general equation
y = cos ( x - h ) + k
where, h and k are points which shows the shifting of function on x and y axes.
On comparing general equation with given equation g(x)
so we get h = -a and k = -b.
Thus, the phrase which describe g(x) for parents function p(x) is:
" Graph shifts a units in negative x direction and b units in negative y direction".

that apply.
S = 8 + 36
S = 36 + 36 + 36 + 36 + 36 + 36 + 36 + 36

{(32)-3/4)3/4}4/5 pls solve it
Answers
Answer:
18 3/4
Step-by-step explanation:
Solve {(32)-3/4)3/4}4/5
Expand the inner parenthesis
{(32)-3/4)3/4}4/5
= {3/4(32) - (3/4)(3/4)}*4/5
= {3(8)- 9/16} * 4/5
= {24 - 9/16}* 4/5
= 4/5(24) - 4/5(9/16)
= 96/5 - 36/80
= 96/5 - 9/20
Fine the LCM
= 96(4)-9/20
= (384-9)/20
= 375/20
= 18 15/20
= 18 3/4
Hence the required result is 18 3/4

BAD=67
Answer:
m<BAD = 67
Step-by-step explanation:
The given figure is a parallelogram. Consecutive angles in a parallelogram are supplementary, meaning that their angle measures sum up to 180 degrees. Using this, one can say,
m<D + m<A = 180
Substitute,
m<ADB + m<BDC + m<A = 180
71 + 42 + m<A = 180
113 + m<A = 180
Inverse operations,
113 + m<A = 180
-113 -113
m<A = 67

LEFT SIDE/ LEFT EQUATION: if you multiply 1 and (b + 14) together, the result becomes the numerator of the fraction (with 2 being the denominator).
Once you do that, you will notice that both sides/both equations are exactly the same.
Thus, if you put in ANY number for variable b, the solution of both sides/both equations will always be the same and work.
The answer is: "There are infinetly many solutions"

Answer:
1. The applicable theorem is the midsegment theorem
y = 5 cm
Step-by-step explanation:
The given quadrilateral MATH is an isosceles trapezoid,
The bases of the isosceles trapezoid are
b₁ = [tex]\overline{MA}[/tex] and b₂ = [tex]\overline{HT}[/tex]
The median of the isosceles trapezoid = [tex]\overline{LV}[/tex]
MA = 3·y - 2
HT = 2·y + 4
LV = 8.5 cm
The midsegment theorem states that the median of a trapezoid is parallel to the bases of the trapezoid and is equal to half the length of the sum of the bases of the trapezoid
The median of a trapezoid = (1/2)×(b₁ + b₂)
Therefore, we have;
The median of the isosceles trapezoid, LV, given as follows;
LV = 8.5 = (1/2)×((3·y - 2) + (2·y + 4))
LV = 8.5 = (1/2)×(5·y + 2) =
2 × 8.5 = (5·y + 2)
17 = 5·y + 2
∴ 5·y = 17 - 2 = 15
y = 15/3 = 5
y = 5 cm

Answer:
8 in approx
Step-by-step explanation:
Given data
volume = 100 cubic inches
radius= 2 inches
The expression for the volume of a cylinder is given as
v=πr^2h
substitute
100= 3.14*2^2h
100= 12.56h
h= 100/12.56
h=7.9 in
Hence the height is 8in approx
