Step-by-step explanation:

the greatest common factor (GCF) is 7.

it is 9×7, 7×7 and 11×7.

so the total number of pencils is

7×(9 + 7 + 11) = 7×27 = 189

I need help with rational and irrational numbers here is the question.
4vir4ik [10]

Answer:

The correct answer choices are:

1) It is a real number

2) It is an irrational number

Step-by-step explanation:

So we have the number:

\sqrt2

First, let's define each of the terms:

Real numbers are all of the irrational and rational numbers. If a number is irrational or rational, then they are a real number. Any number that does not include the imaginary number i is real (you'll learn this eventually. It's actually really interesting!).

Irrational numbers are the numbers that do not terminate nor repeat. Examples include π or √3. Note that numbers like 1/3 which is .3333 is <em>not </em>irrational because they are repeating. π, on the other hand, does not repeat and never ends.

Rational numbers are the numbers that terminate or repeat. They also include the integers, whole numbers, and natural numbers.

So, the √2. First, it's real because it doesn't deal with imaginaries.

Next, use a calculator and calculate √2. We can see that it is about 1.41423562... This number does not repeat. And it does not terminate (end). In other words, √2 is a irrational numbers.

Since it is irrational, it cannot be rational. Since it's not rational, it cannot be an integer, whole number, or a natural number.

Therefore, the correct answer choices are:

1) It is a real number

2) It is an irrational number

Find the direction cosines and direction angles of the given vector. (Round the direction angles to two decimal places.) a = 5,
Travka [436]

Answer:

Step-by-step explanation:

given is a vector as (5,9,3)

a = (5,9,3)

To find out direction cosines

First let us calculate modulus of vector a

||a|| =\sqrt{5^2+9^2+3^2} \\=\sqrt{25+81+9} \\=\sqrt{115}

Direction ratios are (5,9,3)

Magnitude of vector a = \sqrt{115}

So direction cosines would be

(\frac{5}{\sqrt{115} } ,\frac{9}{\sqrt{115} },\frac{3}{\sqrt{115} })

Angles would be

(\alpha, \beta, \gamma) = arccos ((\frac{5}{\sqrt{115} } ,\frac{9}{\sqrt{115} },\frac{3}{\sqrt{115} })

=cos inverse  (0.4662, 0.8393, 0.2798)

= (62.21, 32.93,32,94)

What is the measure of the missing angle in the triangle below? <br> Plz help
gavmur [86]
The answer to the missing angle is

answer = 52°

reason:

the angle is 38° and the angle w the square is 90° so you add 90° which would get u 128° and now you subtract 180° from 128° which will get you 52°
