Luke listens to the three most popular songs on the radio this week. The length of each song is shown. #1 song: 3 1/2 minutes #2 song: 2 57 /60 minutes #3 song: 4 3/4 minutes. What is the length of the three songs all together?
song 1: 3 1/2 minutes
song 2: 2 57 /60 minutes
song 3: 4 3/4 minutes
Total length of the three songs = song 1 + song 2 + song 3
= (3 1/2 + 2 57/60 + 4 3/4) minutes
= 7/2 + 177/60 + 19/4
= (210+177+285) / 60
= 672/60
= 56/5
= 11 1/5 minutes
Total length of the three songs = 11 1/5 minutes

Rotate an isosceles right triangle around a line that contains the triangle's hypotenuse
Answer:
See attachment 2 for the rotation
Step-by-step explanation:
The question has a missing figure
See attachment 1 for the missing figure of the isosceles right-triangle
Required
Rotate around the hypotenuse
From the attachment, the hypotenuse is along the blue vertical line along the y-axis.
So, when the isosceles triangle is rotated around the hypotenuse, the result of the rotation we get a composite figure that has two congruent solids.
Which is a cone of radius and height equal to half of the hypotenuse
See attachment 2 for the rotation

Una caja de carton se ha disenado para qu contenga 184cm cubicos. Si su altura es de 10cm, cual es el area de la base?
Answer:
18.4 cm²
Step-by-step explanation:
Una caja de carton se ha disenado para qu contenga 184cm cubicos. Si su altura es de 10cm, cual es el area de la base?
Volumen = Área de la base × Altura
Área de la base = Volumen / Altura
= 184 cm³ / 10 cm
Área de la base = 18.4 cm²
Por lo tanto, el área de la base es de 18.4 cm².

en las matematicas para que concepto se usan las letras?
Answer:
En matemáticas, las letras son utilizadas en las ecuaciones, para representar a través de ellas valores no conocidos que deben ser dilucidados por quien realiza la ecuación. Las letras más utilizadas con este propósito son las letras X e Y.
Así, por ejemplo, se da una suma con un valor numérico y un valor faltante denominado X, con un resultado también numérico, con lo cual el valor de X surgirá del resultado de la ecuación planteada. Por ejemplo:
8 + X = 10
X = 10 - 8
X = 2
8 + 2 = 10
1. Predict the height ( in cm) of boy
who is 30 months old.
2. Predict the age of a boy who is approximately 115 cm tall.
Use the linear model equation y=0.58x+72.27.
Answer:
Step-by-step explanation:
It'd be wise to say what is represented by each x and y. I will assume that x represents the age of the child in months and y the height in cm.
Then, if the height is 115 cm, 115 cm = 0.58x + 72.27. Must solve this for x:
115 cm - 72.27 cm
x = ---------------------------- = 73.7 cm (about 29 inches, which is reasonable)
0.58
If the child is 30 months old, x = 30 and y (the height) is
0.58(30) + 72.27 cm = 89.7 cm (about 35.3 cm, also reasonable)

Write an expression in terms of x that could be used to determine the surface area of a cube with a side length of x inches.
Answer:
A=6x²
Step-by-step explanation:
A cube is an object which is three-dimensional. A cube has six square faces.
If the side length = x inches
The area of a square = x²
Therefore, the expression for the surface area of a cube(with 6 square faces) with a side length of x is given as:
A=6x²

write the product in standard form: (x+4)(x-4)
Answer:
x² - 16
Step-by-step explanation:
Use the FOIL method here where
F = first
O = outer
I = inner
L = last
F = x * x = x²
O = -4 * x = -4x
I = 4 * x = 4x
L = -4 * 4 = -16
Combine the terms to get x² - 16.

I need some help finding the volume of a sphere with a diameter of 18.6cm. The website says the answer I got from my calculator was wrong! Help would be greatly appreciated!
Answer:
Volume, V = 3367.6 cm³
Step-by-step explanation:
Given the following data;
Diameter = 18.6 cm
Radius = diameter/2 = 18.6/2 = 9.3 cm
Pie, π = 3.14
To find the volume of the sphere;
Mathematically, the volume of a sphere is given by the formula;
[tex] Volume \; of \; a \; sphere = \frac {4}{3} \pi r^{3} [/tex]
Where;
r is the radius of the sphere.
Substituting into the formula, we have;
[tex] V = \frac {4}{3} * 3.14 * 9.3^{3} [/tex]
[tex] V = 4.186666667 * 804.357 [/tex]
Volume, V = 3367.6 cm³
