Answer: The approximate absentee rate that day would be 8.09%.

Step-by-step explanation:

Since we have given that

Number of students who were absent = 36

Total number of  students = 445

We need to find the approximate absentee rate that day :

Rate of absentee of that day would be

\dfrac{\text{Number of absentee}}{\text{Total number of students}}\times 100\\\\=\dfrac{36}{445}\times 100\\\\=8.09\%

Hence, the approximate absentee rate that day would be 8.09%.

zzz [600]

Answer:

[8, 3]

Step-by-step explanation:

-3⁄7[-7x + 14y = -14] ↷

{3x - 6y = 6

{-3x + 7y = -3

_____________

y = 3 [Plug this back into both equations to get an x-value of 8]; 8 = x

So, using the Elimination Method, I decided to eliminate the <em>x</em>'s by multiplying the top equation by -3⁄7 to end up with 3x, so I can cancel that with -3x in the bottom equation [<em>additive inverses</em> ALWAYS result in zero], and to be genuine, it really does not matter which variable you choose to eliminate.

**I have a video that explains how to solve a system of equations in two to three variables. It is titled "Solving Systems of Equations". I encourage you to watch the video and gain alot more knowledge from it, so you can better understand the concept.

Write an explicit furmula for the question below <br> 40 points!!!!!!!!!!!!!
Usimov [2.4K]

Answer:

aₙ = a₁ . 5⁽ⁿ⁻¹⁾

Step-by-step explanation:

The first term in the sequence is a₁ = 6.

a₂ = 30. a₃ = 150.

We see that each consecutive term is multiplies by 5 to arrive at the next term.

That is: a₂ = 30 = a₁ . $ 5^{2 - 1}  = 5 $ = 6.5 = 30.

Similarly, a₃ = 150 = 6 $ \times $ $ 5^{3 - 1} = 5^2 = 25 $

Generalizing this, we have:

aₙ = a₁ . $ 5^{n - 1} $

This is called the recursive formula of the sequence.

3x - 20 = 4 PLEASE EXPLAIN HOW YOU GOT THE ANSWER IN STEPS!
sammy [17]

Answer:

x = 8

Step-by-step explanation:

3x - 20 = 4

add 20 to both sides

3x - 20 + 20 = 4 + 20

3x = 24

divide both sides by 3

\frac{3x}{3} = \frac{24}{3}

x = 8
