Answer:
B
Step-by-step explanation:
the answer is (15+11)+4=15+(11+4)
The expression (15+11) + 4 = 15 + (11+4) best represents the commutative property of addition. The correct option is B.
What is cumulative property?The cumulative property states that if the position of the numbers when they are in addition is changed then it will not affect the final result of the addition. If altering the operands' order has no effect on the outcome, the binary operation is commutative in mathematics.
The commutative property basically states that x+y can be flipped yet have the same meaning so x+y = y+x ~.
In the option B the expression (15+11) + 4 = 15 + (11+4) representing the cumulative property. On changing the summation terms the final answer will not change.
Therefore, the expression (15+11) + 4 = 15 + (11+4) best represents the commutative property of addition. The correct option is B.

HELP PLS!!! You invested $25,000 in two accounts paying 7% and 8% annual interest, respectively. If the total interest earned for the year was $1900, how much was invested at each rate?
Residents of the town of Maple Grove who are connected to the municipal water supply are billed a fixed amount monthly plus a charge for each cubic foot of water used. A household using 1900 cubic feet was billed $156, while one using 2600 cubic feet was billed $184. (a) What is the charge per cubic foot? dollars per cubic foot (b) Write an equation for the total cost, c, of a resident's water, , as a function of cubic feet of water used. c(w) = dollars c) How many cubic feet of water used would lead to a bill of $216? cubic feet
9514 1404 393
Answer:
$0.04 per cubic footc(w) = 0.04w +803400 cubic feetStep-by-step explanation:
(a, b) We are given two pairs of values:
(w, c) = (1900, 156) and (2600, 184)
so we can write the equation of the relationship using the 2-point form of the equation of a line.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
c = (184 -156)/(2600 -1900)(w -1900) +156 . . . . . substitute given points
c = 28/700(w -1900) +156
c(w) = 0.04w +80
The charge per cubic foot is $0.04.
__
(c) For a bill of $216, the amount of water used is ...
216 = 0.04w +80
136 = 0.04w
3400 = w
Use of 3400 cubic feet of water would lead to a bill of $216.

What is Unitary method?"It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Steps to Use Unitary MethodFirst, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.
Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.
Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.
Given:
Total money = $225.00
Cost of one ball =$55
So, remaining money after buying the ball
=225- 55
= $170
Now,
game of bowling costs $3.50,
So, number of bowling can be played is
=170/3.5
=48.75
= 48 bowling

What is -2/3 - (-1/2)
Answer: -1/6
Step-by-step explanation: Start by changing the minus a negative
to plus a positive, so we have -2/3 + 1/2.
Since our denominators of 3 and 2 have no factors in common,
our least common denominator is 3 · 2 or 6.
In order to get a denominator of 6 in each fraction,
we multiply top and bottom of the first fraction by 2
and top and bottom of the second fraction by 3.
That gives us -4/6 + 3/6 which simplifies to -1/6.

Answer:
y(y² + 1)(y² - y - 1)(y² + y - 1)Step-by-step explanation:
y⁷ + y = y(y⁶ + 1) = y((y²)³ + 1³) = y(y² + 1)(y⁴ - y² + 1) = y(y² + 1)(y⁴ - 2y² + 1 - y²) = y(y² + 1)((y² - 1)² - y²) = y(y² + 1)(y² - y - 1)(y² + y - 1)Used identities:
a³ + b³ = (a + b)(a² - ab + b²)a² - b² = (a + b)(a - b)a² - 2ab + b² = (a - b)²Algebra
= y⁷ + y
= y(y⁶ + 1³)
= y(y² + 1)(y⁴ - 2y² + 1 - y²)
= y(y² + 1)(y² - y - 1)(y² - y - 1)

If [tex]\displaystyle \lim_{x \to 1} \frac{f(x)-8}{x-1} = 10,[/tex] find [tex]\lim_{x \to 1} f(x).[/tex]
We are given the equation:
[tex]\lim_{x \to 1} \frac{f(x)-8}{x-1} = 10[/tex]
which can be rewritten as:
[tex]\frac{\lim_{x \to 1}[f(x)-8]}{\lim_{x \to 1}[x-1]} = 10[/tex]
[tex]\lim_{x \to 1}[f(x)-8] = 10*\lim_{x \to 1}[x-1][/tex]
[tex]\lim_{x \to 1}[f(x)-8] = \lim_{x \to 1}[10x-10][/tex]
which means that..
[tex]f(x) - 8 = 10x - 10[/tex]
[tex]f(x) = 10x - 10 + 8[/tex]
[tex]f(x) = 10x - 2[/tex]
Finding the limit:
[tex]\lim_{x \to 1} f(x) = \lim_{x \to 1} (10x - 2)[/tex]
[tex]\lim_{x \to 1} f(x) = 10(1) - 2[/tex]
[tex]\lim_{x \to 1} f(x) = 8[/tex]
Answer:
8.
Step-by-step explanation:
lim x --> 1 of 10x - 10 / (x - 1)
= lim x -->1 of 10/1 ( Because when x = 1 the function = 0/0 so we can apply
L'hopitals rule which states that that if f(x)/ g(x) = 0/0 when x = limit value, then the limit is = f'(x) / g'(x))
So f(x) - 8 = 10x - 10
f(x) = 10x - 10 + 8
f(x) = 10x - 2
- and the limit as x ---> 1 of this is
10(1) - 2
= 8.

A triangle has side lengths of (7n-2p)(7n−2p) centimeters, (2n+4q)(2n+4q) centimeters, and (q-5p)(q−5p) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?
Answer:
(7n-2p)(7n−2p) + (2n+4q)(2n+4q) + (q-5p)(q−5p) OR
53n² +29p² +17q² -14np +8nq -10pq
Step-by-step explanation:
The perimeter is found by adding all the side lengths.
P = (7n-2p)(7n−2p) + (2n+4q)(2n+4q) + (q-5p)(q−5p)
We know that (a+b)(a+b) = (a+b)², and (a-b)(a-b) = (a-b)²
P = (7n-2p)² + (2n+4q)² + (q-5p)²
We know that (a+b)² = a²+b²+2ab, and (a-b)² = a²+b²-2ab
P = 49n² + 4p² - 14np +4n² +16q² + 8nq +q²+25p² -10pq
Combine like terms
P = 53n² +29p² +17q² -14np +8nq -10pqAnswer the following.

Callie wants to build a fence halfway between her house and her neighbor's house. How far away from Callie's house should the fence be built?
The distance of the fence from Callie's house is [tex]\frac{y}{2}[/tex]
Let the total distance between Callie and her neighbor's house = y
The distance from Callie + distance from her neighbor's house = y
The distance from Callie = half of the total distance
In mathematical equation, the distance of the fence from Callie's house is calculated as:
[tex]distance = \frac{y}{2} = \frac{total\ distance \ between \ Callie \ and \ her \ neighbor }{2}[/tex]
Thus, the distance of the fence from Callie's house is [tex]\frac{y}{2}[/tex]
