The temperature of a hot steak starts at 140f and decreases at 5f per minute what will the temperature of this steak after a certain number of minutes

Answers

Answer:

T(m) = (140 - 5m)

Step-by-step explanation:

Given that :

Initial temperature, a = 140 F

Rate of decrease = 5 F per minute

Given a certain Number of minutes, m

Temperature, T after m minutes ;

Using the formula :

Final temperature = Initial temperature - 5*number of minutes)

T(m) = (140 - 5m)

Given that ; m = 10

T(10) = 140 - 5(10)

T(10) = 140 - 50

T(10) = 90 F

Answer:

[tex]x = -5\frac{1}{2}[/tex] is the solution

Step-by-step explanation:

Given

[tex]3x - 1 = 5x + 10[/tex] --- Correct expression

[tex]x = -5\frac{1}{2}[/tex]

Required

Determine if the given solution is correct

To do this, we simply solve for x in the given equation.

So, we have:

[tex]3x - 1 = 5x + 10[/tex]

Collect like terms

[tex]3x - 5x = 1 + 10[/tex]

[tex]-2x = 11[/tex]

Divide both sides by -2

[tex]\frac{-2x}{-2} = \frac{11}{-2}[/tex]

[tex]x = -\frac{11}{2}[/tex]

[tex]x = -5\frac{1}{2}[/tex]

Find an expression in its simplest form for the perimeter of this shape

Answers

Answer:

(18p + 18)

Explanation:

the perimeter of the shape is the sum of all its sides. we are given the individual lengths of all the sides except for the horizontal one at the bottom and the vertical one between (2p + 5) and (3p + 4), but they can easily be calculated using the other values.

the horizontal length at the bottom is the sum of (2p + 5) and (3p + 4), or (5p + 9).

the vertical length is the difference between 4p and 2p, which is 2p.

now, we can add all of these values together:

4p + (2p + 5) + 2p + (3p + 4) + 2p + (5p + 9)

= 4p + 2p + 2p + 3p + 2p + 5p + 5 + 4 + 9

= 18p + 18

A teacher changed to grading from 50 points + 5 for each correct answer to 50 points + 7 for each correct answer. What would change: the slope. The y intercept, both the slope and the y intercept or nothing

Answers

Answer:

The slope

Step-by-step explanation:

Given that:

Initial grading ; For each correct answer : 50 points + 5

New grading ; For each correct answer = 50 + 7 points

The reading coukd be expressed in slope intercept form of an equation as :

Initial grading :

y = 50 + 5x

New grading :

y = 50 + 7x

y = total score ; x = number of correct answers

The change in y per unit change in x which is the slope, is the only difference in the two equations, the intercept (50) stays the same.

Therefore, only the slope changes.

Draw a line through the point (2, 2) with a slope of 1. Draw a line through the point (1,−1) with a slope of 1.

Answers

Answer:

should look like this

Step-by-step explanation:

equations are y=x and y = -x if needed

The equation of the lines are y = x and y = x - 2

A linear equation is given by:

y = mx + b;

where y, x are variables, m is the slope of the line and b is the y intercept

The equation of a line passing through the point (2, 2) with a slope of 1 is:

[tex]y-y_1=m(x-x_1)\\\\y-2=1(x-2)\\\\y = x[/tex]

The equation of a line passing through the point (1, -1) with a slope of 1 is:

[tex]y-y_1=m(x-x_1)\\\\y-(-1)=1(x-1)\\\\y = x-2[/tex]

Therefore both lines have equation of y = x and y = x - 2. The graphs of the lines are attached.

How to solve systems of inequalities

Answers

Answer:

Determine whether an ordered pair is a solution of a system of linear inequalities.

Solve a system of linear inequalities by graphing

Solve applications of systems of inequalities

Step-by-step explanation:

Graph x>2 on a number line.

Determine whether the ordered pair \left(3,\frac{1}{2}\right) is a solution to the system \left\{\begin{array}{c}x+2y=4\hfill \\ y=6x\hfill \end{array}.

Determine Whether an Ordered Pair is a Solution of a System of Linear Inequalities

The definition of a system of linear inequalities is very similar to the definition of a system of linear equations.

System of Linear Inequalities

Two or more linear inequalities grouped together form a system of linear inequalities.

A system of linear inequalities looks like a system of linear equations, but it has inequalities instead of equations. A system of two linear inequalities is shown below.

\left\{\begin{array}{c}x+4y\ge 10\hfill \\ 3x-2y<12\hfill \end{array}

To solve a system of linear inequalities, we will find values of the variables that are solutions to both inequalities. We solve the system by using the graphs of each inequality and show the solution as a graph. We will find the region on the plane that contains all ordered pairs \left(x,y\right) that make both inequalities true.

Solutions of a System of Linear Inequalities

Solutions of a system of linear inequalities are the values of the variables that make all the inequalities true.

The solution of a system of linear inequalities is shown as a shaded region in the x-y coordinate system that includes all the points whose ordered pairs make the inequalities true.

To determine if an ordered pair is a solution to a system of two inequalities, we substitute the values of the variables into each inequality. If the ordered pair makes both inequalities true, it is a solution to the system. s

My God - Efficient Teams A coding competition is being organized on the HackerRank platform. The participants need to be grouped into teams where each team has exactly two candidates. There are n candidates, where each candidate has a skill denoted by skill[i]. A total of ( n/2) teams are to be formed, such that the total skill of each team is the same. The efficiency of a team is defined as the product of the skill levels of its two members, i.e., for the-skills [1, 3], the efficiency of the team is 13=3. Find the sum of efficiencies of all teams that can be formed satisfying the criteria. If there is no way to create teams that satisfy the conditions, return 1. Note: It can be shown that the answer is always unique. Example The skills of the candidates are skill =[1,2,3,2]. They can be paired as [[1, 3], [2, 2]].
