A taxi cab company charges a flat amount of $5.00 plus a rate of $3.00 per mile traveled. Part A: If the total cost of the fare was $41.00, then which of the following equations can be used to determine the number of miles traveled, x?What is the total number of miles traveled, x, if the fare was $41.00?
Answer:
5 + 3x = 41
x = 12 miles
Step-by-step explanation:
A taxi cab company charges a flat amount of $5.00 plus a rate of $3.00 per mile traveled.
Let x is the number of miles traveled.
If the total cost of the fare was $41.00 then
5 + 3x = 41 eq. 1
The above equation can be used to determine the number of miles traveled.
Solving the equation for x,
5 + 3x = 41
3x = 41 - 5
3x = 36
x = 36/3
x = 12 miles
Therefore, 12 is the total number of miles traveled if the fare was $41.00.
Calvin is painting an area that is 115 square feet. He is able to paint 2.5 square feet every 2 minutes. At this rate , how long will it take calvin to paint the entire paint the entire area.
Answer:
Calvin will paint the entire area in 92 minutes or 1 hour 32 minutes.
Step-by-step explanation:
First of all we know that the total surface are that Calvin is painting is 115 square feet.
The rate at which Calvin is painting refers to the surface area he covers every 2 minutes. This is 2.5 square feet every 2 minutes.
we can set up a relation to solve this problem
If Calvin paints [tex]2.5 ft^{2}[/tex] in 2 minutes
He will paint [tex]115 ft^{2}[/tex] in [tex]x[/tex] minutes
By cross multiplying, we have [tex]x= \frac{2 \times 115}{2.5}=92 minutes[/tex]
Hence Calvin will paint the entire area in 92 minutes or 1 hour 32 minutes.
Frank and Linda just finished a meal and received their bill for $47.60. They would like to leave their server a 20 percent tip. Which expression could be used to find the total bill including gratuity?
0.2 (47.60)
47.60 minus left-bracket (0.2) (47.60) right-bracket
47.60 + left-bracket (0.2) (47.60) right-bracket
0.8 (47.60)
Answer:
Step-by-step explanation:
Tips = 20% of 47.60
= (20/100) * 47.60
= 0.20 * 47.60
Total bill = 47.60 + (0.2)*(47.60)
Answer:
the answer is 47.60 + (0.2)*(47.60)

Is every trapezoid a rectangle
Answer:
No, a trapezoid is not a rectangle.
This is because trapezoids by definition have only one pair of parallel sides while rectangles must have at least two sets of opposite parallel sides. Also, trapezoids do not have 90 degrees at every angle like rectangles do.

Two fifths of the performance were sold out. There were 15 performances that were not sold out. a. How many performances were there? b. What was the ratio sold out to not sold out performances?
Answer:
25
2:3
Step-by-step explanation:
2/5 were sold out
5/5 - 2/5 = 3/5
That means 3/5 were not sold out
p = performances
there were 15 that were not sold out
3/5 * p = 15
Multiply each side by 5/3
5/3 *3/5 p = 15*5/3
p = 25
There were 25 performances
sold out to not sold out
2/5 : 3/5
Multiply by 5

The coordinates of the reflection are
Answer:
The point after the reflection: [tex](-4,-8)[/tex]
Step-by-step explanation:
-Statement: If you reflect the point [tex](x,y)[/tex] across x-axis or the y-axis, then the [tex]x[/tex] and the [tex]y[/tex] of the point can change either positive, negative or the same, depending on where the point is located on a graph.
-So, if you reflect the point [tex](-4,8)[/tex] across x-axis, then the point after the reflection, would be [tex](-4, -8)[/tex] :
The following point: [tex](-4, 8)[/tex]
The point after the reflection: [tex](-4,-8)[/tex]

Se desea construir una letra "ene" mayúscula de tal manera que sus segmentos paralelos midan 25 cm y el
segmento oblicuo que une ambos mida 65 cm. ¿Qué distancia en línea recta separará los segmentos paralelos?
Answer:
La distancia en línea recta que separa los segmentos paralelos es 60cm.
Step-by-step explanation:
Esta pregunta se puede resolver usando el teorema de Pitágoras:
[tex] \\ c^2 = a^2 + b^2[/tex] [1]
Es decir, en triángulos rectágulos, el cuadrado de la hipotenusa es igual a la suma de los cuadrados de los catetos de dicho triángulo. Un triángulo es rectángulo cuando el ángulo que forman sus dos catetos es recto o de 90 grados sexagesimales.
Es importante notar que la letra N tiene dos lados paralelos y el lado oblicuo (o inclinado) une ambos lados paralelos. Pues bien, la letra N puede formar dos triángulos iguales. Escojamos uno de ellos para obtener la respuesta, es decir, la distancia en línea recta que separa los segmentos paralelos (segmentos verticales de la N)
El lado oblicuo (inclinado) es la hipotenusa de ese triángulo (es decir, c). De los catetos, uno está representado por uno de los segmentos paralelos (verticales) de la N (digamos que es b), y, el otro cateto, es la distancia horizontal que une ambos segmentos verticales (digamos que es a).
Si unimos el segmento inferior del cateto b con el extremo inferior de la hipotenusa, se forma el cateto a. Este cateto a forma un ángulo recto con el cateto b y, por lo tanto, forma un triángulo recto. Los lados de un triángulo recto pueden resolverse usando el teorema de Pitágoras, descrito en [1].
Usando [1] y despejando a, tenemos:
[tex] \\ c^2 = a^2 + b^2[/tex]
Restamos [tex] \\ b^2[/tex] de ambos lados de la igualdad:
[tex] \\ c^2 - b^2 = a^2 + b^2 - b^2[/tex]
[tex] \\ c^2 - b^2 = a^2 + 0[/tex]
[tex] \\ c^2 - b^2 = a^2[/tex]
Luego
[tex] \\ a^2 = c^2 - b^2[/tex]
Extrayendo la raíz cuadrada en cada lado de la igualdad:
[tex] \\ \sqrt{a^2} = \sqrt{c^2 - b^2}[/tex]
Entonces
[tex] \\ a = \sqrt{c^2 - b^2}[/tex]
Asimismo, tenemos que [tex] \\ c = 65[/tex]cm y [tex] \\ b = 25[/tex]cm
Entonces,
[tex] \\ a = \sqrt{65^2 - 25^2}[/tex]
[tex] \\ a = \sqrt{4225 - 625}[/tex]
[tex] \\ a = \sqrt{3600}[/tex]
[tex] \\ a = 60[/tex]cm
De esta manera, el valor de a, o la distancia en línea recta que separa los segmentos paralelos, es 60cm.
Podemos comprobar el resultado anterior haciendo uso del mismo teorema de Pitágoras:
[tex] \\ 65^2 = 60^2 + 25^2[/tex]
[tex] \\ 4225 = 3600 + 625[/tex]
[tex] \\ 4225 = 4225[/tex]
En la figura anexa se aprecia gráficamente lo anteriormente explicado.
The function h ( x ) = 1 x − 1 h ( x ) = 1 x - 1 can be expressed in the form f ( g ( x ) ) f ( g ( x ) ) , where g ( x ) = ( x − 1 ) g ( x ) = ( x - 1 ) , and f ( x ) f ( x ) is defined as:
Answer: f(x) = 1^(x + 1)
Step-by-step explanation:
we have that h(x) = 1^x
and h(x) = f(g(x))
This mean that we are evaluating the function f(y) in the point y = g(x)
where g(x) = x - 1
then:
f(g(x) = f(x - 1) = h(x) = 1^x
then we should have that:
f(x) = 1^(x + 1)
then:
f(x - 1) = 1^(x - 1 + 1) = 1^x

4(t+25) = (t+50) - 4 (0.15t)
Answer:
4(t+25) = (t+50) - 4 (0.15t)
4t + 100 = t + 50 - 0.6t
4t + 100 = 50 + 0.4t
4t - 0.4t + 100 = 50 + 0.4t - 0.4t
3.6t + 100 = 50
3.6t + 100 - 100 = 50 - 100
3.6t = -50
3.6t / 3.6 = -50 / 3.6
t = - 13.9
