Solve y/2+22=38 for y

Answer:

P=2,3

Step-by-step explanation:

3p=5+2

Then you divide

3/3=7/3

the error difference is simply 24 - 21 = 3.

now, if we take 24(corrected value) to be the 100%, what's 3 off of it in percentage?

\(\begin{array}{ccll} amount&\%\\ \cline{1-2} 24 & 100\\ 3& x \end{array} \implies \cfrac{24}{3}~~=~~\cfrac{100}{x} \\\\\\ 8 ~~=~~ \cfrac{ 100 }{ x }\implies 8x=100\implies x=\cfrac{100}{8}\implies x=12.5\)

In an instruction like "z = x y," the symbols x, y, and z are examples of variables.

Variables are placeholders that represent unknown or changing values in mathematical expressions or equations. They allow us to generalize mathematical relationships and solve problems using algebraic methods.

In mathematics, variables are symbols that represent unknown or varying quantities. They are used to express mathematical relationships, equations, and formulas.

In the given instruction "z = x y," the symbols x, y, and z are variables.

In this case, x and y represent the input values, and z represents the output or result of the mathematical operation defined by the equation.

Variables are used extensively in algebra to solve equations, manipulate expressions, and analyze mathematical relationships. They enable us to express and solve problems symbolically, without knowing the specific values of the variables.

By assigning specific values to variables, we can evaluate expressions, solve equations, and find solutions to mathematical problems.

Variables can represent a wide range of quantities, including numbers, measurements, constants, or even abstract concepts. They provide flexibility and generality in mathematical modeling and problem-solving.

By using variables, we can establish connections between different mathematical quantities and derive meaningful conclusions based on their relationships.

Explanation:

The 0.5+8 simplifies to 8.5

It might help to think of 8 as 8.0

So,

y(0.5+8)

y(8.5)

8.5y

Or you could say it like this

y(0.5+8)

0.5y+8y

8.5y

the second step results from the distributive property.

Answer:

600 boys

800 girls

Step-by-step explanation:

Ratio is 3:4

let total number of boys be x

3/4=x/1400-x

4x=3(1400-x)

4x=4200-3x

7x=4200

x=600

First Picture ⇒ [B] a = -2, b = 1, and c = -5

Second Picture ⇒ First step: Identify a = 1, b = 3, c = -4

                          \(x=\frac{-3\pm \sqrt{3^2-4\cdot \:1\cdot \left(-4\right)}}{2\cdot \:1}\)

                             \(x=\frac{-3\pm 5\sqrt{25}}{2}\)

                           \(x=\frac{-3\pm \:5}{2}\)

                        \(x=\frac{-3+5}{2},\:x=\frac{-3-5}{2\c}\)

Third Picture ⇒ Missing Info

Fourth Picture ⇒ [A] \(x=-\frac{5}{2},\:x=-3\)

Fifth Picture ⇒ \(x=\frac{5\pm\sqrt{1} }{2}\)

Step-by-step explanation:

-------------------------------------------------------------------------------------------------------------

Identify the a,b, and c-values for this equation:

y = -2x²  + x -5  

Quadratic Formula:

ax²+bx+c=0

−2x²+1x−5=0

a = -2, b = 1, and c = -5

-------------------------------------------------------------------------------------------------------------

Order the steps for solving this equation using the quadratic formula.

x²  + 3x - 4 = 0

Solving to see what are the steps:

First step: Identify a = 1, b = 3, c = -4

\(x=\frac{-3\pm \sqrt{3^2-4\cdot \:1\cdot \left(-4\right)}}{2\cdot \:1}\)

\(x=\frac{-3\pm 5\sqrt{25}}{2}\)

\(x=\frac{-3\pm \:5}{2}\)

\(x_1=\frac{-3+5}{2\cdot \:1},\:x_2=\frac{-3-5}{2\cdot \:1}\)

-------------------------------------------------------------------------------------------------------------

Use the quadratic formula to find the solution set for 2x² + 15 = -11x.

Add 11x to both sides:

2x² + 15+11x = -11x+11x

Simplify

2x² + 11x+15 = 0

Now solve with quadratic formula..

\(x_{1,\:2}=\frac{-11\pm \sqrt{11^2-4\cdot \:2\cdot \:15}}{2\cdot \:2}\)

\(x_{1,\:2}=\frac{-11\pm \:1}{2\cdot \:2}\)

\(x_1=\frac{-11+1}{2\cdot \:2},\:x_2=\frac{-11-1}{2\cdot \:2}\)

\(x=-\frac{5}{2},\:x=-3\)

Hence, [A] \(x=-\frac{5}{2},\:x=-3\)

-------------------------------------------------------------------------------------------------------------

Suppose you are solving a quadratic equation and this is your work so far...

x  ²  - 5x + 6 = 0

Thus, we have:

\(x=\frac{-\left(-5\right)\pm \sqrt{\left(-5\right)^2-4\cdot \:1\cdot \:6}}{2\cdot \:1}\)

\(x=\frac{-\left(-5\right)\pm \:1}{2\cdot \:1}\)

\(x=\frac{5\pm\sqrt{1} }{2}\)

\(x_1=\frac{-\left(-5\right)+1}{2\cdot \:1},\:x_2=\frac{-\left(-5\right)-1}{2\cdot \:1}\)

\(x=3,x=2\)

\( 32x^{15} \)

Step-by-step explanation:

\( (2x^3)^5 = 2^5(x^3)^5 = 2^5x^{15} = 32x^{15} \)

Answer:

a

Step-by-step explanation:

Let's call the number of children who swam at the public pool "x". The number of adults who swam would be 762 - x. The total revenue from the children would be $1.50 per child * x children = $1.50x. The total revenue from the adults would be $2.00 per adult * (762 - x) adults = $2.00(762 - x).

We know that the total revenue was $1268.50, so we can set up an equation:

$1.50x + $2.00(762 - x) = $1268.50

Expanding the equation:

$1.50x + $1524 - $2.00x = $1268.50

Simplifying the equation:

$0.50x + $1524 = $1268.50

Subtracting $1524 from both sides:

$0.50x = -$255.50

Dividing both sides by -0.50:

x = 511

So, there were 511 children who swam at the public pool, and 762 - 511 = 251 adults.

\(\cfrac{x}{50}=\cfrac{75}{x}\implies x^2=(50)(75)\implies x^2=3750\implies x=\sqrt{3750}\implies x=25\sqrt{6}\)

The geometric mean of two numbers 50 and 75 is 61.23.

We have,

To find the geometric mean of two numbers, multiply the numbers together and then take the square root of the result.

Geometric Mean = √(Number 1 * Number 2)

Given the numbers 50 and 75:

Geometric Mean = √(50 * 75)

= √(3750)

≈ 61.23

Therefore,

The geometric mean of two numbers 50 and 75 is 61.23.

a) The FDA limits the amount of plastic in licorice to no more than 75%. Which of the following represents this constraint?

The correct inequality which represents this constraint is ×1−3×2<=0.

Explanation:

We are given that Twizzlers has 2 ingredients: plastic (×1) and red goop (x2) and that the FDA limits the amount of plastic in licorice to no more than 75%.In terms of the amount of plastic and red goop in Twizzlers, the above information can be represented as follows:

0.75 × 1 ≤ ×2Dividing both sides by 1,

we have:×1 - 3×2 ≤ 0

Therefore, the correct inequality which represents this constraint is ×1 − 3×2 ≤ 0.

b) Let ×1= beer; ×2= pizza. Which of the following represents this constraint?

Ido owns a pizzeria that is also a popular place to get a beer. The state of Virginia hates bars, and requires all alcohol selling establishments to have alcohol revenues less than food revenues (or something like that...).

At his current prices, this means Ido must sell no more than 3 beers per pizza.

Using the given notations, we need to represent the given constraint mathematically. Since Ido wants to sell no more than 3 beers per pizza, this can be written as:×1/×2 ≤ 3

Multiplying both sides by ×2, we have:×1 ≤ 3×2

Therefore, the correct inequality which represents this constraint is 3×2 − ×1 ≥ 0.

In the event of describing the likelihood that the team rebounds the next missed shot is likely, and the number of rebounds that the team should expect to have missed in 15  shots is 10.5 rebounds.

Given

Number of shots missed by the given team is 7

Total number of shots fired is 10

a) Then, moving on to the first part of the question

Here we have to apply probability to evaluate the likelihood of the given team rebounds the next missed shot.

Then,

Probability = no of shots attended / total number of shots fired

Probability = 7 /10

Then the event is likely

b) Now the second part

Then the number of rebounds the given team expect to have in the next 15 missed shots
