Answer:

Step-by-step explanation:

Using Pythagorean theorem

17^2 = b^2 + 8^2

17 x 17 = b^2 + 8 x 8

289 = b^2 + 64

Subtract 64 from both sides

289 - 64 = b^2 + 64 - 64

225 = b^2

b^2 = 225

b = square root of 225

b = 15

Simplify.<br> (WILL GIVE BRAINLIEST)

Novosadov [1.4K]

Answer:

$\frac{\sqrt{x} }{2x}$

Step-by-step explanation:

Rationalize the denominator first (keep in mind we are NOT solving this because there is no equals sign here. We are merely simplifying.)

$\frac{\sqrt{5x} }{x\sqrt{20} } *\frac{\sqrt{20} }{\sqrt{20} } =\frac{\sqrt{100x} }{20x}$

Now simplify by taking the square root of 100 to get:

$\frac{10\sqrt{x} }{20x}$

Divide numerator and denomiator by 10 to get:

$\frac{\sqrt{x} }{2x}$

A rectangular solid measures 5 cm long by 3 cm wide by 1 cm high. What is the surface-area-to-volume ratio

siniylev [52]

Answer:

Answer below

Step-by-step explanation:

Yo uneed to find the Area/volume

The area of the rectangle is 2×(5cm×1cm)+2(3cm×1cm)+2(5cm×3cm)=10cm+6cm+30cm=36cm^2

Volume=5cm×3cm×1cm=15cm^3

Ratio: 36cm^2/15cm^3=12cm^2/5cm^3
