Find the value of x, rounded to the nearest tenth

tatyana61 [14]

Answer:

x ≈ 8.9

Step-by-step explanation:

Given a tangent and a secant from an external point to the circle, the the square of the tangent is equal to the product of the external part of the secant and the entire secant, that is

x² = 8(8 + 2) = 8 × 10 = 80 ( take the square root of both sides )

x = $\sqrt{80}$ ≈ 8.9 ( to the nearest tenth )

A three-layer chocolate cake costs $24 and serves 16 . What is the cost per slice?

Fantom [35]

Hi there!

»»————-　★　————-««

I believe your answer is:

$1.50

»»————-　★　————-««

Here’s why:

Assuming that the cake has one slice per person (16 slices):

⸻⸻⸻⸻

$\frac{\text{price}}{\text{slice}}\\\\\rightarrow \frac{24}{16}\\\\\rightarrow \boxed{1.50}$

⸻⸻⸻⸻

Each slice should cost $1.50.

Hope this helps you. I apologize if it’s incorrect.
