Answer:

see explanation

Step-by-step explanation:

given

a² + b² = c² ( isolate b² by subtracting a² from both sides )

b² = c² - a² ( take the square root of both sides )

\sqrt{b^{2} } = ± \sqrt{c^2-a^2}

b = ± \sqrt{c^2-a^2}

BaLLatris [955]

Answer:

x < 293 / 700

Step-by-step explanation:

−35x + 15 > 7/20

Multiplying all through by 20

-700x + 300 > 7

-700x > 7 - 300

-700x > -293

Divide all through by 700

- x > - 293 / 700

Multiply all through by -

x < 293 / 700

HELP someone please!!!! i dont understand
ad-work [718]

Answer:

x = 65.03°

Step-by-step explanation:

To solve for x, we have to apply trigonometric ratio.

Recall: SOH CAH TOA

From the diagram, we know the following:

Reference angle = x

Hypotenuse = 45

Adjacent = 19

Since we know the Hyp and Adj, we would apply CAH, which is:

Cos x = Adj/Hyp

Plug in the values

cos(x) = \frac{19}{45}

x = cos^{-}(\frac{19}{45})

x = 65.0250346°

x = 65.03° (nearest hundredth)

The radius of a cylindrical water tank is 4.5 ft, and its height is 8 ft. What is the volume of the tank?
Brums [2.3K]
The answer is 509 ft^3


Formula:
V = πr^2h
V = 3.14 * 4.5^2 * 8
V = 3.14 * 20.25 * 8
V = 508.68 ft^3

508.68 rounded to the nearest whole number is 509

So the volume of the cylinder is 509 ft^3
