Answer:
The total distance is [tex]d_T = 6250 \ m[/tex]
Step-by-step explanation:
From the question we are told that
The distance from bailey start point to her friends house is [tex]d = 3 \ km = 3*1000 = 3000 \ m[/tex]
The distance covered going to and from the park is [tex]d_2 = 250 m[/tex]
The total distance covered is mathematically evaluated as
[tex]d_T = (2 * d_1) + d_2[/tex]
Substituting values
[tex]d_T = (2 * 3000) + 250[/tex]
[tex]d_T = 6250 \ m[/tex]
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
2: 3
What is the y-intercept of the line with equation y = 3x + 2
Answer:
The y-intercept is 2.
Step-by-step explanation:
We can find the y-intercept by looking at the linear equation y = mx + b.
m = slope
b = y-intercept
====================================================
Let's find the y-intercept of this line.
You should notice that the equation is written in Slope-Intercept Form:
[tex]\bigstar{\boxed{\pmb{y=mx+b}}}[/tex]
Where
m -> slope
b -> y-intercept
In the equation y=mx+b, the y-intercept is b, and in the equation y=3x+2, 2 is the y-intercept.
=========================================================
note:-Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I will comment and/or edit my answer :)
Dora bought cupcakes for her sister's birthday party. 20% of the 90 cupcakes had sprinkles on top. How many cupcakes had sprinkles?
Answer:
18 sprinkles
Step-by-step explanation:
20% of 90 cupcakes
20% = 1/5
1/5 of 90
1 x 90 = 90
90 / 5 = 18
Answer:
18 cupcakes
Step-by-step explanation:
If there were 90 cupcakes and 20% of the cupcakes had sprinkles on top, the number of cupcakes with sprinkles on top would be
⇒ 20% of 90 cupcakes
⇒ [tex]\frac{20}{100} * 90 cupcakes[/tex]
⇒ (2*9) cupcakes
⇒ 18 cupcakes

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

PLEASE HELP 10 POINTS WILL GIVE BRAINLIEST: Which geometric solid is the best model for the head of a human being?
A. Cylinder
B. Cone
C. Pyramid
D. Sphere
Answer:
sphere
Step-by-step explanation:
Human heads are close to circles and sometimes are circles
Sphere is the best model for the head of a human being.
A human head definitely doesn't represent a Cone neither a Pyramid.
Now a cylinder is a solid which is circular at its edges and straight in its length which clearly does not model the human head. Now the Sphere, it does closely represent the outside figure of a human head.
Thus Sphere is the best model for a human head.
Therefore option D, sphere is the correct answer.

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

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.

Which of the points shown below are on the line given by the equation y = x + 3
Answer: B
Step-by-step explanation:
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]
