Answer:
En cada expresión queremos obtener 100 en el denominador.
Notar que en la primer eq. tendríamos:
a) 3/5 = (20/20)*(3/5) = (20*3)/(20*5) = 60/100 = 0.6 (corresponde a 60%)
b) 11/4 = ?
Acá el denominador es 4
tenemos que encontrar un número k tal que:
k*4 = 100
k = 100/4 = 25
Entonces podemos multiplicar denominador y numerador por 25.
11/4 = (25/25)*(11/4) = (25*11)/(25*4) = 275/100 = 2.75 (corresponde a 275%)
c) 4/20
el denominador es 20, entonces tenemos que resolver:
20*k = 100
k = 100/20 = 5
multiplicamos denominador y numerador por 5:
(5/5)*(4/20) = (5*4)/(5*20) = 20/100 = 0.2 (corresponde al 20%)
d) 9/5
el denominador es 5, entonces debemos resolver:
5*k = 100
k = 100/5 = 20
Debemos multiplicar denominador y numerador por 20
(20/20)*(9/5) = (20*9)/(20*5) = 180/100 = 1.8 (corresponde a 180%)
e) 10/200 = 5/100 = 0.05 (corresponde al 5%)
f) 8/200
Se resuelve de similar forma al de arriba (que ya tenias resuelto).
Aca el denominador eso 200, entonces tenemos que tener:
200*k = 100
k = 100/200 = 1/2
Entonces multiplicamos numerador y denominador por 1/2
(1/2/1/2)*(8/200) = (8*1/2)/(200*1/2) = 4/100 = 0.04 (corresponde al 4%)
g) 30/300
aca el denominador es 300
Entonces:
300*k = 100
k = 100/300 = 1/3
Multiplicamos numerador y denominador por 1/3
(1/3/1/3)*(30/300) = (30*1/3)/(300*1/3) = 10/100 = 0.1 (corresponde al 10%)
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
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

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
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.

Newton's law of gravitation state that the force F of attraction between two bodies varies jointly as their masses M1 and M2 and inversely as the square of the distance between them. Two bodies whose centers are 500mi apart attract each other with a force of 15lb.What will be the force of attraction if their masses were tripled and the distance between their centers doubled?

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.
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.

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
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

Two students spent the same amount of
money on their lunches and got the same
number of toppings. One bought a steak
burger and paid $3.80 plus $0.40 for each
topping. The other bought a hamburger
and paid $3.20 plus $0.60 for each
topping. How many toppings did each
student get?
0.60-0.40=0.20
3.80-3.20=0.60
0.60 divided by 0.20=3
Hence, each student got 3 toppings each.

How to solve systems of inequalities

Step-by-step explanation:

Solve the inequality 2a<5a+12.
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
