Answer:
Step 2: Commutative Property
Step 3: Associative Property
Step-by-step explanation:
According to the Commutative Property of Addition: Two real numbers can be added in either order.
a + b = b + a
Therefore, she used the Commutative Property in Step 2.
In Step 3, she used the Associative Property, in which the grouping of the addends does not change the sum.

A collection of coins is worth $4.40 and is made up of nickels and dimes. If there are 75 coins total, how many dimes are in the collection?
Answers
Answer:
5.00
Step-by-step explanation:
Answer:
13
Step-by-step explanation:
the nickels can add up to 60 nickels for 3$. then, i just started adding dimes until i get to $1.30 out of the remaining $1.40 (because we subtracted $3 from 60 nickels). we now have 73 coins. two more nickels adds 0.10, which finally gets us to the missing 1.40.
this probably didn't make sense, but I'm 98% sure its right.

[tex]2\sqrt{29}+\sqrt{53}+5[/tex]
Step-by-step explanation:
The distance between A and B is a vertical distance of [tex]2[/tex] and a horizontal distance of [tex]5[/tex]. By the Pythagorean Theorem, [tex]AB=\sqrt{2^2+5^2}=\sqrt{29}[/tex].
The distance between B and C is [tex]5[/tex] by counting squares.
The distance between C and D is a vertical distance of [tex]2[/tex] and a horizontal distance of [tex]7[/tex]. By the Pythagorean Theorem, [tex]CD=\sqrt{2^2+7^2}=\sqrt{53}[/tex].
The distance between D and A is a vertical distance of 5 and a horizontal distance of [tex]2[/tex]. By the Pythagorean Theorem, [tex]DA=\sqrt{5^2+2^2}=\sqrt{29}[/tex].
So, the answer is [tex]\boxed{2\sqrt{29}+\sqrt{53}+5}[/tex]

Trapezoid ZOID is congruent to trapezoid TRAP. If vertices 2 and have coordinates (0, -2) and (0, -5) respectively, which of the following could be possible coordinates for vertex
(4.-0,5)
0 (-3.5, -3)
(-1.5, 1
(-4.5.-5)
Answers
The trapezoids are congruent if the corresponding sides of each trapezoid are equal
The option that gives the possible coordinates for the vertex I is the option;
[tex]\underline{(-4.5, -5)}[/tex]
Reason:
The given coordinates of the trapezoid TRAP = T(3, 5), P(3 2), R(6, 5), and A(7.5, 2)
The given coordinates of the trapezoid ZOID = Z(0, -2), and D(0, -5)
Required: The possible coordinates for a vertex on ZOID
Solution:
The given points of the trapezoid are the height of the trapezoid ZOID
The possible vertex of I, and O are;
I(4.5, -5), I(-4.5, -5), O(3, -2), O(-3, -2)Therefore;
The option that gives the possible coordinates (position) of a vertex I is the option [tex]\underline{(-4.5, -5)}[/tex]

What are the coordinates of the point at H?
A.
(-3 , -3)
B.
(-3 , 3)
C.
(3 , 3)
D.
(3 , -3)
Answers
Answer:
it would be B, it goes x axis to y axis
Explanation:
Start where the x and y axis meet. This is the origin.
Move to the left 3 units. You'll be directly under point H.
Then move 3 units up to arrive at point H.
Moving to the left 3 means x = -3. Moving up 3 means y = 3.
Together we have the location (x,y) = (-3,3)
You can think of the x,y location as if it was an address on a map or longitude/latitude coordinates.

Problem 7, please answer the following step by step.
Answers
(a) This is the same as computing 4⁵⁵ (mod 11). We have
4² ≡ 16 ≡ 5 (mod 11)
4³ ≡ 4 • 5 ≡ 20 ≡ 9 (mod 11)
4⁴ ≡ 4 • 9 ≡ 36 ≡ 3 (mod 11)
4⁵ ≡ 4 • 3 ≡ 12 ≡ 1 (mod 11)
Then from here,
4⁵⁵ ≡ (4⁵)¹⁰ • 4⁵ ≡ 1¹⁰ • 1⁵ ≡ 1 (mod 11)
(b) Each term in the sum
4ⁿ + 4ⁿ⁺¹ + 4ⁿ⁺² + 4ⁿ⁺³ + 4ⁿ⁺⁴
has a common factor of 4ⁿ, so this sum is the same as
4ⁿ (1 + 4 + 16 + 64 + 256) = 4ⁿ • 341 = 4ⁿ • 11 • 31
So the sum is indeed divisible by 11 for all integers n.
(c) Since 4ⁿ = (2ⁿ)², we know the sum is also divisible by 11 when a = 2.
