=  12/12 - 4/12

units

Answers

Answer:

Volume of the given sphere = 4.19 units³

Step-by-step explanation:

Volume of a sphere is given by the expression,

V = [tex]\frac{4}{3}\pi r^{3}[/tex]

Here, r = radius of the sphere

From the picture attached,

Radius of the sphere 'r' = 1 unit

Volume of the given sphere =  [tex]\frac{4}{3}\pi (1)^3[/tex]

                                               = [tex]\frac{4}{3}\pi[/tex]

                                               = [tex]\frac{4}{3}(3.14)[/tex]

                                               = 4.187

                                               ≈ 4.19 units³

A bus travels from town A to town B. If the bus's speed is 50 km/hr, it will arrive in town B 42 min later than scheduled. If the bus increases its speed by \displaystyle \frac{50}{9}
9
50

m/sec, it will arrive in town B 30 min earlier than scheduled. Find:
A) The distance between the two towns;
B) The bus's scheduled time of arrival in B;
C) The speed of the bus when it's on schedule.

Answers

Answer:

60 km/hr

Step-by-step explanation:

First we will determine the speed of the bus following it's increase. The speed is increased by:

50m/9sec=50.60.60/9/1000 .km/hr=20 km/hr

Therefore, the new speed is V = 50 + 20 + = 70

km/hr. If x is the number of hours according to the schedule, then at the speed of 50 km/hr the bus travels from A to B within ( x + 42/60 ) hr. When the speed of the bus is V = 70 km/hr, the travel time is x -30/60 hr. Then:

50(x+42/60)=70(x-30/60)

5(x+7/10)=7(x-1/2)

7/2+7/2=7x-5x

2x = 7

x=7/2 hr

So, the bus is scheduled to make the trip in 3 he 30 minutes.

The distance between the two towns is 70 ( 7/2 – 1/2 ) = 70 • 3 = 210 km and the scheduled speed is:

270/7/2=60km/hr

the polynomial y = x^{5} + x^{3} - x^{2} - 1 factors into (x^{2} + 1) (x^{3} - 1). what is the multiplicity of the root (x^{3} - 1)?

Answers

Answer:

The multiplicity of the root is 1

Step-by-step explanation:

Firstly, we need to understand what multiplicity is

By multiplicity, we simply refer to the number of times we have the certain root repeating itself

From the factorization, each of the given roots were only repeated once

That indicates that the given multiplicity is 1

Answers

Answer:

Step-by-step explanation:

This figure better be a square, otherwise there is no answer.

The diagonals of a square intersect at right angles, so d = 90 degrees. That property comes from the rhombus.

Squares have equal sides and the opposite sides are parallel. The triangle containing c is isosceles. The lower right corner is a right angle. So c must equal 45 degrees since the angle on the lower left must equal 45 degrees as well

Answer

c = 45

d = 90

Answers

Answer:

0.1. B) 50%

0.2 A) Psicología

Step-by-step explanation:

01. Dejemos que 'x' e 'y' representen el porcentaje de boquichicos y carachamas en la piscifactoría, tenemos;

Dado que el 30% de los boquichicos es el 20% del número de carachamas

30% x = 20% y

∴ 0.3 · x = 0.2 · y

Por lo tanto, tenemos;

x / y = 0,2 / 0,3 = 2/3

Por lo tanto, por cada 100% de pescado, tenemos;

x + y = 100%

x = 2/3 · y

2/3 · y + y = 100%

5 · años / 3 = 100

y = 100 × 3/5 = 60%

El porcentaje de carachamas en la finca, y = 60%

∴ x = 100% - y = 100% - 60% = 40%

El porcentaje de boquichicos en la finca, x = 40%

Por lo tanto, tenemos el 80% del pescado en la granja, obtenemos;

Si hay 100 peces en la granja, 80% = 80 peces

Pero el número de los 100 peces que son boquichicos en la granja = 40% × 100 = 40 peces

Por lo tanto, los boquichicos son la mitad del 80% del número de peces o el 50% de los peces en la piscifactoría.

La opción correcta es;

B) 50%

02. Tenemos;

El costo de un libro de psicología> El costo de un libro en inglés

El costo de un libro de matemáticas> El costo de un libro de historia

El costo de un libro de psicología> El costo de un libro de matemáticas

Por lo tanto, tenemos;

El costo de un libro de psicología> El costo de un libro de matemáticas> El costo de un libro de historia

∴ El libro de Psicología es más caro que todos los demás libros y, por tanto, es el libro más caro

La opción correcta es;

A) Psicología
