Write an inequality for the situation. all real numbers at most –9.5 or at least 5.5A. –9.5 ≤ b ≤ 5.5

B. b ≥ –9.5 or b ≥ 5.5

C. b ≤ –9.5 or b ≤ 5.5

D. b ≤ –9.5 or b ≥ 5.5

Answers

Answer 1
Answer:

Answer:

option (c) is correct.

The given expression all real numbers at most –9.5 or at least 5.5 is written as   b ≤ –9.5  or  b ≥ 5.5

Step-by-step explanation:

Given  expression all real numbers at most –9.5 or at least 5.5

We have to represent the given expression mathematically and choose the correct from given options.

Consider the given expression  all real numbers at most –9.5 or at least 5.5

Let the real number be represented by b

then the given expression contain two terms

1)  all real numbers at most –9.5  

Mathematically written as  b ≤ –9.5    .....(1)

2) all real numbers at least 5.5

Mathematically written as  b ≥ 5.5       ....(2)

Thus, the given expression   all real numbers at most –9.5 or at least 5.5 is written as   b ≤ –9.5  or  b ≥ 5.5

Thus, option (c) is correct.
Answer 2
Answer: Hello,

If b represents any real number,

b<=-9.5
or
5.5<=b


Answer  C

Find geometric mean between 3 and 6

Answers

geometric\ mean\ between \ a\ and\ b\ = √(a\cdot b) \n----------------------\n\ngeometric\ mean= √(3\cdot6) = √(3\cdot3\cdot2) =3\cdot √(2)
Call the geometric mean ' G '.

Then (3 / G) = (G / 6)

This is a proportion, and may be "cross-multiplied":

G² = 18

G = √18 = about 4.2426... (rounded)

Berta determined that the solution is (–2, 3). Which could have been the equation Berta found in step 1? 4x = 0 5x = 10 5x = –10 5x = –25

Answers

The equation that Berta determined could be 5x = - 10.

What is a numerical expression?

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, Berta determined that the solution is (- 2, 3).

From the given options the only x-coordinate value satisfying is

5x = - 10.

As at x = - 2.

5(-2) = - 10.

- 10 = - 10.

The solution (- 2, 3) can also be called as an ordered pair.

A jet travels 470 miles in 2 hours. At this rate, how far could the jet fly in 9 hours? What is the rate of speed of the jet?

Answers

First determine how many miles the jet files in one hour:

470/2 =235 miles/hour

We want to know how many hours the jet could fly in 9 hours, so we multiply this value by 9.

235 x 9 = 2115 miles

Therefore, the jet could fly 2115 miles in 9 hours.

Answer:

235 miles per hour and 2,115 miles in 9 hours
