Answer:

the length of the missing side is 2

Step-by-step explanation:

Use a^2 + b^2 = c^2

a = 4

b = ?

c = 2sqrt5

4^2 + b^2 = (2sqrt5)^2

16 + b^2 = 20

subtract 16 from both sides

b^2 = 4

take the sqrt of both sides

b = 2

16 POINTS HELP ASAP plzzzzzzzzz

Answer:

$\large\boxed{\large\boxed{\sqrt{3}$

Explanation:

You are comparing irrational numbers.

By inspection, i.e. at first sight you can only compare $\sqrt{3} \text{ }and\text{ } 2\sqrt{3}$ because they have the same radicand.

You can order: $\sqrt{3}$

You can introduce the 2 inside the radical by squaring it:

$2\sqrt{3}=\sqrt{2^2\times3}=\sqrt{12}$

Since 5 is between 3 and 12, you can order:

$\sqrt{3}$

Which is:

$\sqrt{3}$

You must know that π ≈ 3.14.

5 is less than 9 and the square root of 9 is 3; hence, $\sqrt{5}$ and $\sqrt{5}$

Now you must determine whether π is less than or greater than $\sqrt{12}$

Using a calculator or probing numbers between 3 and 4 you get $\sqrt{12} \approx3.46$

Hence, the complete order is:

$\sqrt{3}$

M(x) = 4x + 15; m(x) = 7

stealth61 [152]

Hi there! :)

$\huge\boxed{x = -2}$

m(x) = 4x + 15

Find the value of "x" that would satisfy m(x) = 7:

4x + 15 = 7

Subtract 15 from both sides:

4x = -8

Divide both sides by 4:

x = -2.

Pierre Hugo is handling the estate of a prominent businesswoman. The will states that the surviving spouse is to receive one hal

umka21 [38]

Answer:

Each child will receive 0.125 (or 12.5%) of the estate.

Step-by-step explanation:

If the surviving spouse gets one half of the estate, the other half have to be divided among the four surviving children.

So its 0,5 divided among the 4 surviving children. That is 0.125 or 12.5% of the estate.

Each child will receive 0.125 of the estate.
