Dylan hikes 90 miles in 3 days. At that rate, how many days does it take him to hike a total of 240 miles?
Answer:
8 days
Step-by-step explanation:
90/3 = 30 mi/day
240/30 = 8 days
Answer:
it will take him 8 days (7.98 in you don't round)
Step-by-step explanation:
90 -240= 150
150/90 = 1.6666....
1.66 * 3 = 4.98
4.98+3 =7.98 (8 if you round)

I need help please, If triangle JKL is congruent to QRS, find each missing value
Answer:
x = 5, y = 17, z = 8
Step-by-step explanation:
Since the triangles are congruent to each other, corresponding angles and sides are congruent to each other.
JL corresponds with QS so...
3x - 1 = 14
3x = 15
x = 5
RS corresponds with LK so...
y + 10 = 27
y = 17
Angle L corresponds with angle S so...
180 - 58 - 87 = 4z + 3
35 = 4z + 3
32 = 4z
z = 8

6. John predicted that gas prices would raise 3.5% in the month of
January. If gas prices actually rose from $2.25 to $2.30, what was his
percent of error? Plzzz answer
Answer:
37.5%
Step-by-step explanation:
Given data
Initila Price= $2.25
3.5% of $2.25
=3.5/100* 2.25
=0.035*2.25
=0.07875
Hence the expected new price is
=0.07875+2.25
=$2.33
The expected increase
=2.33-2.25
=$0.08
The actual increase
=2.25-2.30
=$0.05
Hence the error is
% error= Actual -Expected/Expected*100
% error= 0.05-0.08/0.08*100
% error= 0.03/0.08*100
% error=0.375*100
% error=37.5%
Hence the error is 37.5%

The rate of change in this equation is:
The initial value in this equation is:
Answer:
0.03
27
Step-by-step explanation:
Use the formula y=mx+b
m= slope
b= y-int
Rate of change can also be interpreted as the slope.
0.03
The initial value can be interpreted as the y-intercept.

The regualar price of a pair of sneackers
is $55 they are on sale for 25%
Answer:
$41 is your answer
Hope it Helps :)
Answer:
$41.25
Step-by-step explanation:
If the shoes regular price was $55 and the shoes are having a sale for 25%, this is how you would do the math.
25% is 25/100 or .25
55 * .25 = $13.75
55 - 13.75 = 41.25

Answer:
x = 23
Step-by-step explanation:
This entire angle makes up 90° b/c of the square box
65 + x + 2 = 90
x + 67 = 90
x = 23
Answer: x=23
Step-by-step explanation:
This is a right angle. A right angle is 90°. It already gives us 65°. So 90-65=25°. We now know (x+2) ° = 25°. 25-2=23.
We can prove this is correct by answering the problem they gave us. (23+2) is 25. 25+65=90° 90° is a right triangle which also happens to be the triangle they have shown us.

An online games club charges $5.75 for the first game download and $2 for each additional
download per month. Write a rule for describing the total monthly fees f as a function of
additional downloaus d. What are the fees for 15 game downloads in a month?
Answer:
a) The rule is;
f = 5.75 + 2d
b) f = $33.75
Step-by-step explanation:
Here, we want to write a rule
The rule is that we have a standard download fee of 5.75 for the first download, and then a download fee of $2 per download for the rest
We have this as;
f = 5.75 + 2(d)
f = 2d + 5.75
Now for 15 downloads;
first download is $5.75, remaking 14 is at a rate of $2 per one
Thus, we have the fee value as;
f = 5.75 + 2(14)
f = 5.75 + 28 = $33.75

De las 30 preguntas del examen de matematicas, por cada respuesta correcta se obtenian 5 puntos y por cada respuesta incorrecta, o pregunta no contestada,se perdian 2 puntos teodolindo obtuvo 94 puntos en este examen ¿cuantas respuestas correctas tuvo?
Answer:
Teodolindo obtuvo 22 respuestas correctas y 8 respuestas incorrectas o no contestadas.
Step-by-step explanation:
Un sistema de ecuaciones lineales, también conocido como sistema lineal de ecuaciones o simplemente sistema lineal, es un conjunto de ecuaciones lineales (es decir, un sistema de ecuaciones en donde cada ecuación es de primer grado), en el cual se relacionan dos o más incógnitas.
En los sistemas de ecuaciones, se debe buscar los valores de las incógnitas, con los cuales al reemplazar, deben dar la solución planteada en ambas ecuaciones.
En este caso se debe establecer un sistema de ecuaciones, donde las variables son:
x: cantidad de respuestas correctasy: cantidad de respuestas incorrectas o no contestadasSiendo 30 preguntas en el examen, se tiene la ecuación:
x + y= 30
Por cada respuesta correcta se obtenían 5 puntos y por cada respuesta incorrecta o pregunta no contestada, se perdían 2 puntos. Teodolindo obtuvo 94 puntos en este examen. Entonces se representa esta situación mediante la expresión:
5*x - 2*y= 94
Entonces el sistema de ecuaciones a resolver es:
[tex]\left \{ {{x+y=30} \atop {5*x-2*y=94}} \right.[/tex]
El método de sustitución consiste en despejar o aislar una de las incógnitas (por ejemplo, x ) y sustituir su expresión en la otra ecuación. De este modo, obtienes una ecuación de primer grado con la otra incógnita, y . Una vez resuelta, calculas el valor de x sustituyendo el valor de y calculado.
Entonces, despejando el valor de x de la primer expresión obtienes:
x= 30 -y
Reemplazando en la segunda ecuación obtienes:
5*(30 -y) - 2*y= 94
Resolviendo:
5*30 - 5*y - 2*y= 94
150 - 5*y - 2*y= 94
- 5*y - 2*y= 94 -150
-7*y= -56
y= (-56)÷(-7)
y= 8
Reemplazando el valor de y obtenido en la expresión x= 30 -y se obtiene:
x= 30 - 8
x=22
Teodolindo obtuvo 22 respuestas correctas y 8 respuestas incorrectas o no contestadas.

Answer:
see attached
Step-by-step explanation:
a) Any set of functions that has a total degree of 4 and a total number of x-intercepts of 4 will do. Shown in the first attachment are 4 linear functions. A quadratic function with two x-intercepts could replace two of the linear functions, or a cubic with 3 x-intercepts could replace 3 of the linear functions.
__
b) Again, the total degree must be 3. Since there can only be one x-intercept, the quadratic factor must have none. A possible choice is shown in the second attachment.
