√5 help

Answers

Answer 1

Answer:

  √5 is irrational

Step-by-step explanation:

A rational number is one that can be written exactly as an integer or ratio of integers. Written as a decimal number, it will have a finite number of digits, or a repeating decimal fraction.

Application

Usually, a number that can only be expressed exactly using a symbol will be irrational. For square roots, any root of an integer other than a perfect square will be irrational.

The integer 5 is not a perfect square. It is between the squares 2²=4 and 3²=9. The square root of 5 is irrational.

__

Additional comment

A reduced fraction whose denominator has factors other than 2 or 5 will translate to a repeating decimal. The number of repeating digits may be as many as 1 less than the denominator. For example, 1/19 has an 18-digit repeating decimal equivalent.

The government estimates 840,000 for equipment, 15,000 for software, and 40,000 per month for wages when the project will take 16 months.

Answers

Answer:

the total cost is $1,495,000

Step-by-step explanation:

The computation of the total cost is shown below:

Let us assume the months be m

Now the equation would be

= Equipment + software + wages

= $840,000 + $15,000 + 40,000m

= $840,000 + $15,000 + $40,000 (16)

= $840,000 + $15,000 + $640,000

= $1,495,000

Hence, the total cost is $1,495,000

. Chris read 25 books in 135 days. At this rate, in how many days will he read another 5 books? Another 10 books?

Answers

Answer:

5 books - 27 days

10 - 54 days

15 books - 81 days

Step-by-step explanation:

First, you need to find how many days it takes to read one book, to do this, simply divide 135 by 25 (135/5=5.4). Then, you multiply that number by the amount of books it wants to know how long it would take him to read (5 and 15 since it asks "another 10". It could also be 54 if it was asking how many for 10 books not including the 5 he would have read). 5*5.4=27, 10*5.4=54, and 15*5.4=81.

How do I round 31732.441804 to the nearest dollar?

Answers

Answer and Step-by-step explanation:

To round to the nearest dollar, you are essentially rounding to the nearest whole number.

This involves looking at the tenths place.

31732.441804

The bolded 4 is in the tenths place (after the decimal), and determines if the number to the left of it rounds up or stay the same.

Since 4 is not greater than or equal to 5, it makes the number stay 2.

So, we get the answer to be $31732.

Proportional
Additive

Answers

Answer:

The answer is proportional

Step-by-step explanation:

I took the test and got 5/5

The given relationship is a proportional relation.

What is proportionality?

In mathematics, proportionality indicates that two quantities or variables are related linearly. If one quantity doubles in size, so does the other; if one of the variables diminishes to 1/10 of its former value, so does the other.

Given that, Steven went to play video games in Games Galore arcade. Games Galore charges $1.50 for each game played

Establishing the equation, we get,

y = 1.50x

Where 1.50 is the slope of the line, and, y is total cost and x is the number of game played.

When x = 2,

y = 1.50X2

y = 3

(2, 3)

When x = 4

y = 1.5X4

y = 6

(4, 6)

When x = 6

y = 1.5X6

y = 9

(6, 9)

Here we see that the value of y is varying from the value of x by 1.5 times.

Hence, The relation is a proportional relation.

Sheila is flying a kite with a string that makes a 59-degree angle with
the sand. If the height of the kite above the ground is 97 feet, how
long is the string? (Please use the exact ratio to calculate the missing
side and round your answer to the nearest hundredth.)

Answers

Answer:

113.16 feet

Step-by-step explanation:

Representing the given details appropriately with a right angle triangle. Let the length of the string for the kite be represented by x. Applying required trigonometric function, we have:

Sin θ = [tex]\frac{opposite}{hypotenuse}[/tex]

Sin [tex]59^{o}[/tex] = [tex]\frac{97}{x}[/tex]

x = [tex]\frac{97}{Sin59^{o} }[/tex]

  = [tex]\frac{97}{0.8572}[/tex]

  = 113.1591

x = 113.16 feet

Thus, the string for the kite is 113.16 feet long.

Answer:

C

Step-by-step explanation:

✔️First, solve for r:

r/2 ≤ 3

Multiply both sides by 2

r/2 × 2 ≤ 3 × 2

r ≤ 6

This implies that possible value of r is equal to 6 or less than 6.

Graphing this on a number line, the line with a shaded circle, indicating that 6 is included, starts at 6 and points to the left.

This indicates that value of r ranges from 6 and below.

The graph is C.
