A cone has a volume 7065in and a height of 30 in what is the radius of the cone?use 3.14 for pi

Answers

Answer:

15 inches.

Step-by-step explanation:

V = 1/3 pi r^2 h

7065 = 1/3 * 3.14 * 30 * r^2

r^2  = 7065 / (1/3 * 3.14 * 30)

r^2 = 7065 / 31.4 = 225

r = sqrt 225 = 15.

What value could you write in after 3x that would make the equation
true for:
1. no values of x ?
2. all values of x ?
3. just one value of x?

Answers

Answer:

Step-by-step explanation:

Answer:

(see my explanation)

Step-by-step explanation:

Basically,

For no value it can be anyhting but 8.

For all values it HAS to be 8.

For just one anything that has "x" in it.

Example:

1. -9

2. +8

3. 7+x or 2x

NOTE: this varies depending on the varible after the x value. (It's not always 8)

☝Example:

5x+2 = 5x + _____

1. 3

2. +2

3. x

The following exchange rate is given: £1 = 1.11 euros. Convert £8 into euros.

Step-by-step explanation:

£1 = 1.11 x £8 = 8.88 (euro)

= 8.88

This is because if £1 = 1.11, it’s just like x’ing 8 by lots of ones. so the answer would be 8.88

A,E, and D are collinear. BCDE is a parallelogram. Find m

Answers

Answer:

B. 29º

Step-by-step explanation:

Given that BCDE is a parallelogram, then [tex]BE \parallel CD[/tex] and A, E and D are collinear. Then, angle E inside triangle ABE and angle D inside parallelogram BCDE have the same measure. That is:

[tex]\angle D = \angle E = 51^{\circ}[/tex] (1)

In addition, the sum of internal angles in triangles equals 180º, which implies that:

[tex]\angle A + \angle B + \angle E = 180^{\circ}[/tex] (2)

If we know that  [tex]\angle B = 100^{\circ}[/tex] and [tex]\angle E = 51^{\circ}[/tex], then [tex]\angle A[/tex] is:

[tex]\angle A = 180^{\circ}-\angle B - \angle E[/tex]

[tex]\angle A = 180^{\circ}-100^{\circ}-51^{\circ}[/tex]

[tex]\angle A = 29^{\circ}[/tex]

Hence, correct answer is B.

The answer would be be 29 degrees

the 100th term of the sequence with the term -1-4n

Answers

Given:

The terms of a sequence are given by

[tex]a_n=-1-4n[/tex]

To find:

The 100th term of the sequence.

Solution:

We have,

[tex]a_n=-1-4n[/tex]

Putting n=100, we get

[tex]a_{100}=-1-4(100)[/tex]

[tex]a_{100}=-1-400[/tex]

[tex]a_{100}=-401[/tex]

Therefore, the 100th term of the given sequence is -401.

find the volume and the total surface area of a cuboide whose dimension 2m, 80cm and 60cm​

Answers

Answer:

Volume= 0.96m^3

TSA= 6.56m^2

Step-by-step explanation:

Given data

Length = 2m

Width= 80cm= 0.8m

Height= 60cm= 0.6m

Volume= L*W*H

Volume= 2*0.8*0.6

Volume= 0.96m^3

TSA=2lw+2lh+2hw

TSA= 2*2*0.8+2*2*0.6+2*0.6*0.8

Una vez visto el estado de la carretera hay que calcular unas dos horas. Este Parque Nacional creado en el ao 1937 abarca los glaciares y se ha convertido en Monumento del Patrimonio Mundial en 1981. Cubre una superficie de 600.000 ha y engloba dos grandes lagos: al norte el Viedma y al sur el Lago Argentino, que es el tercero de Sudamrica y el primero de Argentina por su superficie (1.560 km2). Desde la carretera se puede distinguir una pequea isla solitaria porque no est habitada ni por hombres ni por animales. A la altura de la entrada hay un camino que conduce hacia un soberbio panorama desde el que se puede contemplar el Lago Argentino. Pero desde all todava no se distinguen los glaciares. Su color es asombroso. Es de un azul lechoso inolvidable que los argentinos llaman, en un smil gastronmico, el dulce de glaciar. En efecto, el hielo que forman los glaciares es tan denso y antiguo que tiene un color azul turquesa. Cuando se funde presenta esta hermosa coloracin en el agua. Cuando circula uno tiene la impresin de encontrarse en un mundo surrealista, pues la mayor parte de los rboles estn muertos al no haber podido resistir a las sucesivas inundaciones provocadas por los glaciares.
