Elan Coil [88]

Answer:

(Choice A) A The 1 Seed

Step-by-step explanation:

The computation is shown below:

The highest rate of apple per tree is

For Seed

= 38,614 ÷ 84 = 460 approx

For Sweet and sour

= 75509 ÷ 178 = 424 approx

And, for apple valley

= 135220 ÷ 3212

= 433 approx

As it can be seen that the highest rate per of apple per tree is of seed i.e. 460 approx

hence, the correct option is choice A

PLEASE HELP ive been stuck on this for a long time
Tomtit [17]

Answer:

Below

Step-by-step explanation:

You can use Pythagorean theorem to find the hypotenuse of a right triangle.

a2 + b2 = c2

The square root of 15 = 3.8729.... (a bunch of other numbers)

4^2 + 3.8729^2 = c2

16 + 15 = 31

Now that you have this, you need to find the square root

The square root of 31 = 5.56775436

Rounding this to the tenth it would be: 5.57

Final answer: C = 5.57

hope this helps! :)

Please show your work! I have 3 more of these, and I want to be able to do them by myself.
Radda [10]

Answer:

Step-by-step explanation:

We group the number 5:

5(x² + 3x + 2.25)

Now inside the brackets we'll take the square root of the coefficient of the x and the square root of the last number, then remove the square from the x and write it as a sum:

5(x+1.5)²

What's the idea behind this?

Well, remember that when you have something in the form:

(a+b)²

It actually means:

a² + 2ab + b²

In our case a was x, and b was 2.25. For bringing it into the shorter form we have to take the square root of a and b.

Sorry if you don't understand. Tell me if you need help to get the xoncept better.
