What are expressions?Expressions are mathematical statements that are represented by variables, coefficients and operators
How to determine the equation that represents the associative property of addition?The expression is given as
-15 + 0
The associative property of addition states that
(x + y) + z = x + (y + z)
This means that
(x + y) + z = x + (y + z) is a representation of the associative property of addition
From the list of given options, we have

A. 2 inches
B. 4 inches
C. 6 inches
D. 10 inches
(1 point)
After using 25 square block, a quilt has been prepared by Wei-Min that has an area of 100 square inches. The length of each side of a block is 2 inches by calculating using concept of mensuration.
As per the question statement, Wei-Min makes a square quilt that has an area of 100 square inches and has got 25 square blocks, each the same size. We are supposed to find the length of each side of a block.
Using concept of mensuration,
Area of square quilt = 100 square inches
Number of block used = 25 square blocks
Therefore, area of each block = 100/25 = 4 square inches
As the block is a square, so each side will be equal in length.
Let's assume each side of square be "x" inches
Therefore x^2 = 4
or x = √4
or x = 2 inches

Ganesh spends 60% of his income every month and saves Rs 11120 in a month. Find his monthly income and expenditure.
Monthly income and expenditure of Ganesh will be-16680
Let Ganesh's monthly income be x
The problem can be solved using linear equation
The amount of 60% of his salary is spent which can be written as 60% of x or 0.6x
The amount of money saved by Ganesh = total salary - amount spent
= x - 0.6x
= 0.4x
The amount of savings made by Ganesh as per the question = 11120
Lets equate both the equation
0.4x = 11120
x = (11120 × 100)/ 40
x = 27800
Hence, Ganesh's monthly salary comes out to be 27800
Ganesh's monthly expenditure = 0.6 x= 0.6 × 27800 =16680

How many days would the skier have to go skiing in order to make the season pass less expensive than the daily basis
The skier have to go for 7 days skiing in order to make the season pass less expensive than the daily basis.
Cost of daily pass = $70
Cost of season ski pass = $450
Let the cost of skiing per day = 'x'
Now we will equate the season pass plus ski rentals to daily skiing plus ski rentals :
450 + 30x = 70x + 30x
We have 30x on both sides, so those can cancel out easily :
Then we get,
450 = 70x
Dividing both sides by 70 :
x = 6.42
We can't pay for a partial day, so the skier will have to ski for at least 7 days to make the season pass cheaper than getting daily passes.

A linear function is modelled by the equation which is expressed in slope-intercept form as .f(x) = mx + b.

4.6 years
7.3 years
4.3 years
5.9 years
The longest a blender can last and still be in the lowest 5% of life spans will be 4.6 years. The correct option is A.
What is a normal distribution?The z-score formula can be used to resolve issues with samples that have a normal distribution. The score of a measure X in a collection with mean and standard deviation is given by:
Z = ( X - μ ) / σ
The Z-score calculates the deviation of the measure from the mean in standard deviations. We glance at the z-score table after determining the Z-score to determine the p-value connected to it.
The likelihood that the measure's value is less than X, or the percentile of X, is represented by this p-value. The likelihood that the value of the measure is greater than X is obtained by deducting 1 from the value.
In this problem, we have that:
μ = 5.8, σ = 0.9
Only those on the 5th percentile or lower will be replaced. So the warranty is the value of X when Z has a value of 0.05.
The value of x will be:-
Z = ( X - μ ) / σ
-1.28 = ( X - 5.8 ) / 0.9
X = 4.6
Therefore, the longest a blender can last and still be in the lowest 5% of life spans will be 4.6 years. The correct option is A.

Pitches per inning pitched is a tool used to evaluate how efficient a pitcher is at getting his outs -- or how many pitches he typically needs to use to do his job. Calculating the number is easy enough. It's found by dividing a pitcher's total number of pitches thrown by his total number of innings pitched.
Pitchers with the game's best P/IP rate typically average fewer than 15 pitches per inning. A starting pitcher with those numbers would be able to go seven innings on fewer than 105 pitches.
For all games of eight or more innings, a starting pitcher must pitch at least five complete innings to receive credit as the winning pitcher. For all games of fewer than eight innings, the starting pitcher must pitch at least four innings to get credit for the win. Additionally, the winning pitcher’s team must be in the lead when he is replaced and must remain in the lead for the rest of the game.
b. If the starting pitcher does not pitch enough innings, the win is credited to a relief pitcher in the following manner:
1) The winning relief pitcher shall be the one who is the pitcher of record when his team goes ahead and remains ahead throughout the remainder of the game. No pitcher may receive credit for a victory if the opposing team ties the score or goes ahead after he has left the game.
Exception—If a relief pitcher conforms to the above regulations but pitches briefly and ineffectively, the scorer should not credit him with a win. If a succeeding relief pitcher pitches effectively and helps maintain the lead, the scorer should award the win to that succeeding pitcher.
2) If his team maintains the lead throughout the game, and more than one relief pitcher is used, the scorer shall award the win to the relief pitcher that pitches most effectively, regardless of the number of innings pitched.
3) By pre-arrangement, if three or more pitchers are to be used, the pitcher of record shall be considered the winning pitcher.
c. When a batter or runner is substituted for a pitcher, all runs scored by his team during that inning are to his credit in determining the pitcher of record.
d. The starting pitcher shall be charged with the loss if he is replaced at any time while his team is behind and remains behind for the remainder of the game. Similarly, any relief pitcher who is the pitcher of record when the opposing team assumes the lead and never relinquishes it is charged with the loss.

feet long. If the yard is 34 feet long, how many sections will he need to buy?
Answer:
[tex]7\frac{2}{7}[/tex] sections of fence
Step-by-step explanation:
since we are trying to find how many sections we need and we are given the total length of the yard and the length of each section of the fence, we are going to divide.
you want to divide the 34 yards into the 4 2/3 feet. to make this easier, we can turn 4 [tex]\frac{2}{3}[/tex] into a mixed number. to do this we multiply the 4 by the denominator which is the number on the bottom and add it to the numerator which is the number at the top.
4x3=12
12+2 = 14
[tex]\frac{14}{3}[/tex]
[tex]\frac{34}{1}[/tex] ÷[tex]\frac{14}{3}[/tex]
to divide fractions we multiply by the reciprocal which would be
[tex]\frac{34}{1}[/tex]×[tex]\frac{3}{14}[/tex]
now we just multiply across
34x3= 102
1x14=14
[tex]\frac{102}{14}[/tex]
now the furthest we can simplify this is by dividing the whole thing by 2
51/7
now we turn this back into an improper fraction
we get [tex]7\frac{2}{7}[/tex]
you will need to buy [tex]7\frac{2}{7}\\[/tex] sections of fence
HELP ME PLS If f(x) = 4x+1, find
f(a+h)-f(a)/h
Answer:
it's called the difference quotient of a function
Step-by-step explanation:
f(x+h)-f(x)/h is the slope of the secant line of a function
