If the total number of books checked out of the library at your high school is 14,400 and the student population is about 2400.
Whitepunk [10]

The number of books taken by each student is 6.

<h3>What is an average?</h3>

Average is defined as the ratio of the sum of the number of the data sets to the total number of the data. The average actually determines the middle value of the data.

Given that the total number of books checked out of the library at your high school is 14,400 and the student population is about 2400.

The average is calculated by dividing the sum of the total number of items by the total counts of the items.

Average = 14400 / 2400

Average = 6

Therefore, the number of books taken by each student is 6.

What is the answer of a ?
Scorpion4ik [409]

Answer:

<h2>2.2</h2>

Step-by-step explanation:

Use the cosine law (look at the picture).

We have:

a=a\\b=4\\c=3\\\gamma=32^o

a^2=4^2+3^2-2(4)(3)\cos32^o

\cos32^o\approx0.848 → look at the second picture

a^2=16+9-24(0.848)\\\\a^2=25-20.352\\\\a^2=4.648\to a=\sqrt{4.648}\\\\a\approx2.2

In two or more complete sentences, compare the number of x-intercepts in the graph of f(t) = t^2 to the number of x-intercepts i
Anvisha [2.4K]
Well, minusing 8 from every t just moved theh function to the right 8 units
it had no effect on the number of t intercepts (horizontal is t axis instaead of x axis)

originally, it has 1 t intercept at t=0
now it still has 1 t intercept, but now it is at t=8

The measure of one acute angle is 3 times the sum of the measure of the other acute angle and 8
Anettt [7]
Let x be the unknown angle. 

Make an equation using the formula.

<span>"measure of one acute angle is 3 times" Since we know that x is the one acute angle, we can multiply that by 3 to get 3x.

"</span><span>the sum of" when ever you see the word 'sum' it means that there will be an addition process involved and in this case it also means that 3x will equal to the rest of the equation. (3x=)
</span>
<span>"measure of the other acute angle and 8" We already know that the other angle is x . Since there is no other indicator of the 8 being subtracted, multiplied, and divided and that we know this is an addition problem, we can conclude that 8 will be added to the other angle. (x+8)
</span>
So, now we have the equation and all we have to do is simplify it. 

3x= x+8
-x   -x             *Move constants and variables to opposite sides*
------------
2x=8
---  ---             *Divide by 2 to isolate the variable* 
2    2

x=4

So, I'm assuming you want to know the measure of both angles. All you have to do is plug in the x in the 3x and x+8 depending on which angle you want.

3x
3(4)=12
The measure of the first angle is 12.

x+8
4+8= 12
The measure of the second angle is also 12.
