Se sabe q la suma de tres numeros es de 850. El primer es un tercio del segundo y el tercer número es el doble del segundo.¿Cuales son los numeros apollese en el esquema de barra para solucionar el problema?
Answer:
Primer número = x = 85
Segundo número = y = 255
Tercer número = z = 510
Step-by-step explanation:
Se sabe que la suma de tres números es 850. El primero es un tercio del segundo y el tercer número es el doble del segundo.
Representamos:
Primer número = x
Segundo número = y
Tercer número = z
Se sabe que la suma de tres números es 850.
x + y + z = 850 ...... Ecuación 1
El primero es un tercio del segundo
x = 1/3 años
El tercer número es el doble del segundo.
z = 2 años
Sustituimos 1 / 3y por x y 2y por z en la Ecuación 1
1 / 3y + y + 2y = 850
y / 3 + 3y = 850
Multiplica ambos lados por 3
y + 9y = 850 × 3
10 años = 2550
y = 2550/10
y = 255
Resolviendo para x
x = 1/3 años
x = 1/3 × 255
x = 85
z = 2 años
z = 2 × 255
z = 510
Por eso,
Primer número = x = 85
Segundo número = y = 255
Tercer número = z = 510
graph the parabola. y=(x-3)^2-1
Answer:
Step-by-step explanation:
y = (x-3)²-1
This is the equation for an up-opening parabola with vertex (3,-1).
Find the x-intercepts:
0 = (x-3)²-1
(x-3)² = 1
x-3 = ±1
x = 4, 2
The graph crosses the x-axis at (4,0) and (2,0).
Find the y-intercept:
y = (0-3)²-1 = 8
The graph crosses the y-axis at (0,8).
Plot your four points (3,-1), (4,0), (2,0), (0,8). Draw an up-opening parabola through the points.
for what values of x and y is PQRS and parallelogram
Answer:
x = 2
y = 3
Step-by-step explanation:
Measures of opposite sides of a parallelogram are equal.
Therefore,
PQ = SR
2y + 2 = y + 5
2y - y = 5 - 2
y = 3
QR = PS
2x + 3 = y + 4
2x + 3 = 3 + 4 (y = 3)
2x = 7 - 3
2x = 4
x = 4/2
x = 2
Thus, for x = 2 and y = 3, PQRS is a parallelogram.

Step-by-step explanation:
Use Inverse trig functions to solve for the missing angles
D
8.5
F
E
6.5
Answer:
Angle <E is approximately 40 degrees, and angle <D is approximately 50 degrees
Step-by-step explanation:
Since angle <F is clearly 90 degrees, we can find angle E using the cosine function that relates the adjacent side to the angle with the hypotenuse:
[tex]cos(\theta)=\frac{adj}{hyp} \\cos(E)=\frac{6.5}{8.5}\\E = arccos(\frac{6.5}{8.5})\\E\approx 40.12^o[/tex]
And we use the sin function to deal with angle <D:
[tex]sin(\theta)=\frac{opp}{hyp} \\sin(D)=\frac{6.5}{8.5}\\D = arcsin(\frac{6.5}{8.5})\\D\approx 50^o[/tex]
Line segment JK has endpoints at J(-3,4) and K(3,6). Which is an equation of a line that is perpendicular to line segment JK and passes through the point (3,-12)
Answer:
y = -3x - 3.
Step-by-step explanation:
Find the slope of the line JK:
Slope = (6-4)/(3- (-3))
= 2 / 6
= 1/3.
Therefore the slope of the line perpendicular to it is - 1 / 1/3
= -3.
Now we use the point-slope form of a line to get the required equation:
y - y1 = m(x - x1)
Here m = -3 and (x1, y1) = (3, -12) so we have
y - (-12) = -3(x - 3)
y + 12 = -3x + 9
y = -3x + 9 - 12
y = -3x - 3 is the answer.

Factor completely the given polynomial
x(x + 20) + 11(x + 20)
x(x + 20) + 11(x + 20)=
Answer:
(x + 20)(x + 11)
Step-by-step explanation:
x(x + 20) + 11(x + 20) =
Factor out the common factor of x + 20.
= (x + 20)(x + 11)
The binomials make it look complicated, but this is simpler than you think.
Look at this simpler, but similar, example.
Factor xy + 4y
xy + 4y =
You see clearly that y is a common factor, so you factor out y, and you get
= y(x + 4)
In your problem, you have
x(x + 20) + 11(x + 20) =
where (x + 20) is the common factor.
You factor out the common factor, (x + 20). What is left? x + 11 as a factor, so you get
(x + 20)(x + 11)
In 50 trials both coins land in a shaded box twice. What is the experimental probability that both coins fall into a shaded box?
Answer:
1 / 25
Step-by-step explanation:
Number of trials = 50
Number of successes (number of times both coins land in a shaded box) = 2
Experimental probability = (number of successes / number of trials)
Experimental probability (both coins landing into a shaded box) = 2 / 50
= 1 / 25
what are the rules for multiplying negative numbers?
Answer:
When multiplying negative numbers, just remember 2 things. 1: 2 negative values will always give a positive value. 2: If you only have 1 negative value, your answer will also be negative. Just remember these rules and the rest is simple multiplication.
Answer:
Hi there! Your answer is down below!
Step-by-step explanation:
The rule of how to multiply negatives is simple: For a case where a negative number is multiplied by a positive, the rule above can be restated as: take the positive number, and the negative WITHOUT the minus sign, multiply them and add the inus sign to the product.

the percentage of people who took less than 40 secs to complete a task give answer in 1 decimal place
Answer:
63.6%
Step-by-step explanation:
Total number of people that took the test = 110
People who took less than 40 seconds to complete the task = 30 + 40
= 70
The percentage of the people that took less than 40 seconds to complete the task can be determined as follows:
= [tex]\frac{number of people who used less than 40 seconds}{total number of people who took the task}[/tex] x 1100%
= [tex]\frac{70}{110}[/tex] x 100%
= 0.6364 x 100%
= 63.6%
The percentage of the people that took less than 40 seconds to complete the task is 63.6%.
What is 7.0483 rounded to the nearest hundredth?
Answer:
7.080
Step-by-step explanation:
The rounding off to the number nearest hundredth will be 7.048.
What is rounding off the numbers?When a number is rounded off, its value is maintained but is brought closer to the next number, simplifying the number. For entire numbers as well as decimals at different places of hundreds, tens, tenths, etc., it is done.
A number can be rounded off to its lower value if the number after the decimal is between 0 and 4. The number will be rounded off to its higher value if the number after it is between 5 and 9.
The given number will be rounded off as below:-
7.0483 = 7.048
Therefore, the rounding off to the number nearest hundredth will be 7.048.

Steps for -3(x+2)=4+2x
Answer:
x = -2
Step-by-step explanation:
-3(x + 2) = 4 + 2x
= -3x + -6 = 4 + 2x (Distribution: -3)
= -3x + -2x - 6 = 4 (Moving the variables to the left and change the signs)
= -3x + -2x = 4 + 6 (Move consatnts to the right and change signs)
= -3x - 2x = + 6 --> (Collect like terms)
= -5x = 10 (Then add)
= (divide -5x = 10 by -5)
= x = 2

Write your question here (Keep it simple and clear to get the best answer)When A Number Is Subtracted From 1010001 the Difference Is 910002 find The Number?
Answer:
[tex]99999[/tex]
Step-by-step explanation:
Let the number be [tex]x[/tex].
According to question, if a number is subtracted from 1010001 the difference is 910002.
[tex]1010001-x=910002[/tex]
Transpose [tex]1010001[/tex] to the right side of the equation.
[tex]-x=910002-1010001=-99999\\-x=-99999[/tex]
Multiply both sides by [tex]-1[/tex]
[tex]-x(-1)=-99999(-1)\\x=99999[/tex]
So, if [tex]99999[/tex] is subtracted from 1010001 the difference is 910002.
A workman received $110 for working 20 hours. At the same rate of pay, how many hours must he work to earn $187?
Answer:
He must work 34 hours
Step-by-step explanation:
187×20= 3740
3740÷110= 34
If a workman received $110 for working 20 hours. At the same rate of pay, 33.99 hours must be worked to earn $187.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
It is given that, A workman received $110 for working 20 hours.
We will apply the unitary method in order to solve the given problem.
For $110 he has to work 20 hours.
$110 = 20 hours
For 1 dollar he has to work,
$1 = 20 / 110
$1 =0.1818 hours
The number of hours must he work to earn $187 will be,
$187 = 187 × 0.1818 hours
$187 = 33.99 hours
Thus, if a workman received $110 for working 20 hours. At the same rate of pay, 33.99 hours must be worked to earn $187.
