What are the rules for the order of calculations/operations in an expression?

Evaluating the algebraic expressions for the values given, we have:

a. -7

b. -10.

To evaluate and algebraic expression, plug in the value of the variable given and solve accordingly.

a. Given the algebraic expression, xy + 5.

If x = 2, and y = -6, then substitute x = 2 and y = -6 to evaluate the algebraic expression:

xy + 5

(2)(-6) + 5 [substitution]

= -12 + 5

= -7

b. Given the algebraic expression, x/y - 12, if x = 22 and y = 11, then substitute x = 22 and y = 11 into the expression and evaluate:

x/y - 12

22/11 - 12 [substitution]

= 2 - 12

= -10.

Thus, the values of the expressions when evaluated for the given variables are:

a. -7

What is Asymptote?

The term asymptote means approaching a value or curve arbitrary closely. A line or curve that is asymptotic to given curve is called asymptotic.  

Given,

The function f(x) = 16(1.87)x

Now, We know that

If the value of b < 1, it is a decay while if the value of b > 1, then it is growth. Given the exponential equation below;

f(x) = 16(1.87)x

Since, b = 1.87 which is greater than 1, hence it is a growth. Find the graph attached.

Answer: -16

Step-by-step explanation:

The total number of employees in the company in the year 2015 is 275 employees

Number of employees in the company before increase = 200 employees

Percentage increase in employees between 2005 and 2010 = 25%

Percentage: A percentage is a ratio or fraction where the full value is always 100. Sam, for instance, would have received 30 out of a possible 100 points if he had received 30% on his arithmetic test.

So, the number of employees after the increase = 200+25%of 200

= 200+50 = 250

Percentage increase in employees between 2010 and 2015 = 10%

Number of employees after increase = 250 + 10% of 250

= 250 + 25 = 275 employees

Each game played is independently won by team A with probability p, then team A will surely win the first game.

Given that one team leads 3 to 0, this would mean that in 3 trials, team A won all three games.

The probability of winning 3 out of 3 for team A is

P(A) = P3

The probability of winning 3 out of 3 for team B is

P(B) = (1-P)3

It is given that one of these two scenarios is the case, then the probability it is team A is:

P3/ (P3 + (1-P)3)

The probability that team A would win 0 of the next 4 games is

(1-P)4,

this means the probability that team A wins the series if they are up 3 to 0 is

The number of tablespoons Debnil has is 2 tablespoons

Ratio = 3:1

Ratio: mathematicians use the term "ratio" to compare two or more numbers. It serves as a comparison tool to show how big or tiny an amount is in relation to another. Two quantities are compared using division in a ratio. In this case, the dividend is referred to as the "antecedent" and the divisor as the "consequent."

Let x represent the total number of teaspoons and the tablespoons

Therefore,

6 = 3/4x

x = (6*4)/3

x = 8

So, there are a total of 8 spoons

Now, the number of tablespoons is 1/4 of the total

Hence, the number of tablespoons will be 2

Step-by-step explanation:

given-

two brands of canned dog food are on sale. assume that the cans are the same size. brand a costs $13.60 for eight cans and brand b costs $8.75 for five cans

first-brand a costs $13.60 for eight cans

second- brand b costs $8.75 for five cans

solve first

for 8 cans-->$13.60

then,1 can -->$13.60/8

               =>$1.7

in similar manner we solve for second

for 5 cans-->$8.75

then,1 can -->$8.75/5

Brand a price is less than Brand b.

Unit pricing helps consumers compare the prices of packaged goods when those goods aren't sold in equal quantities.

What is conversion of units?
The process of translating measurements of a given quantity between different units, frequently using multiplicative conversion factors that change the value of the measured quantity without changing its effects, is known as unit conversion. The specific circumstances and the desired result dictate the conversion process. This may be governed by a regulation, contract, set of technical requirements, or other publicly available standards.

What is the conversion factor for inch to mile?
A value in inch when divided by 63360 gives a value in mile.

What is the conversion factor for second to hour?
A value in second when divided by 3600 gives a value in hour.

Given, the speed of Caroline in inches per second = 9 1/2 = 9.5/1 - (i)
Therefore following above literature and dividing numerator by 63360 and denominator by 3600, we get the speed in miles per second.
Thus, required speed = [9.5/63360]/[1/3600) = 0.539 = 0.5

After evaluating for the function f, the value of f(-3) = -12, f(-2) = -2, f(-1) = 4, f(0) = −10

A function is a specific type of relationship that maps inputs to precisely one output. Consider a function as a machine for useful insight. The domain of the function, which describes the types of input that the machine will accept, states that it will produce one and only one output for each input.

A function's fundamental notation is of the form f( x), where x is the input variable and f is the function's name. "F of X" should be read as this. Any time you see this notation, f(x) generally refers to a function's output, though these letters are subject to change.

We have given the function f, to evaluate f(-3), f(-2), f(-1), and f(0)

[tex]f(x)= \begin{cases}-2 x^2+6 & \text { if } x \leq-1 \\ 7 x-10 & \text { if } x > -1\end{cases}[/tex]

f(-3) = -2x² + 6                    (as x < -1)

⇒ -2(-3)² + 6

⇒ -12

f(-2) = -2x² + 6                    (as x < -1)

⇒ -2(-2)² + 6

⇒ -2

f(-1) = -2x² + 6                    (as x < -1)

⇒ -2(-1)² + 6

⇒ 4

f(0) = 7x - 10                      (as x > -1)

Answer:

x = 100° , y = 75° , z = 135°

Step-by-step explanation:

x and 80° are a linear pair and sum to 180° , that is

x + 80° = 180° ( subtract 80° from both sides )

x = 100°

y and 105° are a linear pair and sum to 180° , then

y + 105° = 180° ( subtract 105° from both sides )

y = 75°

the sum of the interior angles of a polygon is

sum = 180° ( n - 2 ) ← n is the number of sides

here n = 5 , then

sum = 180° × 3 = 540°

sum the interior angles and equate to 540°

z + x + 90° + 110° + 105° = 540°

z + 100° + 90° + 110° + 105° = 540°

z + 405° = 540° ( subtract 405° from both sides )

z = 135°
