Answer:

x^3 + 1/x^3 = 488

Step-by-step explanation:

x^2 + 1/x^2 = 62
x^2 + 1/x^2 + 2 = 64
( adding 2 in both sides )
(x + 1/x ) ^2 = 64
x + 1/x = 8

now,

( x+ 1/x ) ^ 3 = 512
x^3 + 1/x^3 + 3 × x × 1/x ( x + 1/x )
x^3 + 1/x^3 + 3 ( 8 )
( since x + 1/x = 8 )
x^3 + 1/x^3 + 24 = 512
x^3 + 1/x^3 = 488

hence, we got x^3 + 1/x^3 = 488

What is the volume of the following cylinder? Do not round your answer. (Use 3.14 for π.)

vlabodo [156]

Answer:

1696.460033 u^3

Step-by-step explanation:

1. The volume formula for a cylinder is $\pi r^2h$ .

2. The radius is half of the width, So r would be 6. (12/2=6)

3. (6)^2 is 36. (6x6)

4. The height is given, which is 15.

5. Plug these numbers into the equation. It should be

$\pi (6)^2(15)$

6. This gives you your answer of 1696.460033 u^3.

88 Is 20 percent of what number?

ValentinkaMS [17]

Answer:

440

Step-by-step explanation:

You can write the problem statement in math terms as ...

88 = 0.20 × (what number)

To solve this, divide by the coefficient of the variable, 0.20.

88/0.20 = (what number)

440 = (what number)

The number you're looking for is 440.

_____

Of course you know that 20% = 20/100 = 0.20.

(% is a shorthand way to write /100.)

The circumference of Earth is 40,075 kilometers. What would be a reasonable estimate for the circumference of Earth?

Illusion [34]

40,075 kilometers?

If you're going for a very rough estimate without knowing that the circumference is 40,075, I'd say to go for 40,000 but I'm not really sure what you're asking.

In Littletown, the probability that a baseball team goes to the city playoffs is

tatuchka [14]

Answer:

C. 0.10

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Goes to the city playoffs

Event B: Goes to the state playoffs.

In Littletown, the probability that a baseball team goes to the city playoffs is 0.20.

This means that $P(A) = 0.2$

The probability that the team goes to the state playoffs given that the team goes to the city playoffs is 0.50.

This means that $P(B|A) = 0.5$

What is the probability that a randomly selected team from Littletown goes to the city and state playoffs?

This is $P(A \cap B)$ . So

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

$P(A \cap B) = P(A)*P(B|A) = 0.2*0.5 = 0.1$

The correct answer is given by option C.
