Answer:

Should be 39 years.

there is 12 inches in a foot. and if the tree grows 4 inches every year, then in 3 years the tree would be 1 foot. 13 x 3 = 39, thus proving that in 39 years, it will be 13 feet tall. I may be wrong but this sounds correct.

Answer:

39 yr

Step-by-step explanation:

Convert "4 inches per year" to "feet per year:"

4 inches 1 ft

-------------- * --------- = (1/3) ft/yr

1 year 12 in

Now we know the growth rate. The time required to reach a certain height is

3 yr

-------- * 13 ft = 39 yr

1 ft

A field has a length of 12 m and a diagonal of 13 m what is the width?

kvv77 [185]

Do Pythagorean Theorem because a rectangle divided in diagonals form right triangles
A^2+b^2=C^2
Plug in the correct numbers and solve
A and B can be switched around but C is always the longest diagonal side which is called the hypotenuse not the Adjacent sides that form a right angle
So with correct solving you should get 5.

n is equal to :

2-1 = 1 so n would have to be 1 in order to be less than 3

Mrs. Williams is deciding between two field trips for her class. The Science Center charges $135 plus $3 per student. The Dino D

Set it up like a regular equation. I used:
$3x+135 \ \textless \ 6x$

As you can see, however, I inserted the "less than" symbol rather than the equal sign because values greater than a certain value can also equal "x". Solve it like a normal equation and you will arrive at:
<u>
</u> $x \ \textgreater \ 45$

This means that, as long as x is greater than 45, "6x" will be greater than "3x+135". Thus, if you bring 46 students, the Science Center will cost less.

If f(x) = x2 + 4x - 12, find f(2).

Illusion [34]

Answer:

-3

Step-by-step explanation:

Please write this as f(x) = x^2 + 4x - 12. "x^2" represents "the square of x."

f(2) is the value of this function when x = 2:

f(2) = f(2) = (2)^2 + 4(2) - 12 = 9 - 12 = -3

Help. only questions 3 & 4 .

Maksim231197 [3]

I'm doing 3

For 3, using a table is very similar to a double number because the numbers are matching up in both ways.

On the bottom of a double number line we have like, for example,-- the bottom of the double number line would have batches. And its 1, 2, 3 ,4 , etc.

And on a table, it would be the same, the numbers on both diagrams have the same methods, have same way of lining things up but they're just drawn differently.

Hope this helped!
