Answer:

(n^4 + ((-1)^n)*n^2) / ((-n)^5 + 3(n^3))

  n^4 + -1/ -1^5 + 3n^3

  n^4 + -1^n / -1^5 +3^3

  n^4/ -1  + 3n^3

  n^4/ -1 + 3x1^3

  n/-1 + 3n

  1/-1+3

  n = 2

3 times 1 and 1/2 times 5 and 1/4 for the volume what the answer
ehidna [41]

Answer:

1 2/3 * 3 1/2 = 35/

6

= 5 5/

6

≅ 5.8333333

Step-by-step explanation:

Conversion a mixed number 1 2/

3

to a improper fraction: 1 2/3 = 1 2/

3

= 1 · 3 + 2/

3

= 3 + 2/

3

= 5/

3

To find new numerator:

a) Multiply the whole number 1 by the denominator 3. Whole number 1 equally 1 * 3/

3

= 3/

3

b) Add the answer from previous step 3 to the numerator 2. New numerator is 3 + 2 = 5

c) Write a previous answer (new numerator 5) over the denominator 3.

One and two thirds is five thirds

Conversion a mixed number 3 1/

2

to a improper fraction: 3 1/2 = 3 1/

2

= 3 · 2 + 1/

2

= 6 + 1/

2

= 7/

2

To find new numerator:

a) Multiply the whole number 3 by the denominator 2. Whole number 3 equally 3 * 2/

2

= 6/

2

b) Add the answer from previous step 6 to the numerator 1. New numerator is 6 + 1 = 7

c) Write a previous answer (new numerator 7) over the denominator 2.

Three and one half is seven halfs

Multiple: 5/

3

* 7/

2

= 5 · 7/

3 · 2

= 35/

6

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(35, 6) = 1. In the next intermediate step, the fraction result cannot be further simplified by canceling.

In words - five thirds multiplied by seven halfs = thirty-five sixths.

Ramon rented a sprayer and a generator on his first job he used each piece of equipment for 6 hours at a total cost of $90 on hi
Oliga [24]
Given:
Sprayer and generator

1st Job: 6 hours each for a total of $90
2nd Job: 4 hours sprayer and 8 hours generator for a total of $100

Let x = spayer ; y = generator

6x + 6y = 90
4x + 8y = 100

6x = 90 - 6y
x = 90/6 - 6y/6
x = 15 - y

4x + 8y = 100
4(15-y) + 8y = 100
60 - 4y + 8y = 100
4y = 100 - 60
4y = 40
y = 40/4
y = 10

x = 15 - y
x = 15 - 10
x = 5

Sprayer = 5 per hour ; generator = 10 per hour

To check:
6x + 6y = 90
6(5) + 6(10) = 90
30 + 60 = 90
90 = 90

<span>4x + 8y = 100
</span>4(5) + 8(10) = 100
20 + 80 = 100
100 = 100

A rack of 15 billiard balls is shown. If one ball is selected at​ random, determine the odds against it containing a number grea
andre [41]

Using the probability and odds concepts, it is found that the odds against it containing a number greater than or equal to 7 is \frac{2}{3}.

  • A probability is the <u>number of desired outcomes divided by the number of total outcomes</u>.
  • An odd is the <u>number of desired outcomes divided by the number of non-desired outcomes</u>.

In the rack, there are 15 balls, numbered from 1 to 15. Of those, <u>6 are less than 7</u>(against it containing a number greater than or equal to 7 is equivalent to it containing a number less than 7), thus:

  • There are 6 desired outcomes.
  • There are 9 non-desired outcomes.

The odd is:

\frac{6}{9} = \frac{2}{3}

The odds against it containing a number greater than or equal to 7 is \frac{2}{3}.

Suppose z is proportional to the square root of x. If z = 717 when x = 9, find the proportionality constant k.??
Dahasolnce [82]

Answer:

  239

Step-by-step explanation:

Write the equation. Fill in the given values, and solve for the unknown,

  z = k√x

  717 = k√9

  k = 717/3 = 239

The constant of proportionality is 239.
