Answer:

n > -2                 or      n < -3

Step-by-step explanation:

|2n+5| > 1

We have two solutions one positive and one negative.  Remember to flip the inequality symbol for the negative

2n+5 > 1         or 2n+5 < -1

Subtract 5 from each side

2n+5-5 > 1-5         2n+5 -5 < -1 -5

2n >-4                    2n < -6

Divide by 2

2n/2 > -4/2             2n/2 < -6/2

n > -2                 or       n < -3

Answer:

About 3

Step-by-step explanation:

Since all real life objects have three dimensions, if you increase the dimensions of an object by a certain factor, the object's volume is greater by the factor cubed.

1500*x^3=45000

x^3=30

x is about 3

Hope this helps!

Nick randomly selects a digit from the set { 0 , 1 , 2 , . . . , 9 } and a letter from the set { A, B, C, . . ., Z } . Matthew w
Alex787 [66]

Answer: 259/260 or 0.99615 (depending on which answer format your teacher wants)

There are 10 numbers in the set {0, 1, 2, ..., 9}. There are 26 letters in the set {A, B, C, ..., Z}. Multiply those values: 10*26 = 260. So there are 260 ways to pick a number followed by a letter. One example is 7P.

There is only one way Matthew can get the correct answer, and there are 260 - 1 = 259 ways to get the wrong answer. We divide 259 over 260 to get the probability of getting the incorrect answer, which is 259/260.

If you need this fraction in decimal form, then use a calculator to find that 259/260 = 0.99615 approximately
