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 = ± $\sqrt{c^2-a^2}$

Solve for x. −35x+15>7/20 Drag and drop a number or symbol into each box to correctly complete the solution.

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

<h3>Hey there! </h3><h3>The second " $x$ " is has invisible $1$ </h3><h3>Here, this is what I meant: $x^ 1$ </h3><h3>So, now your equation looks like this: $x^4(x^1$ $-2)$ </h3><h3>Add the exponents: $4 + 1$ $= 5$ </h3><h3>Therefore your answer should be: $x^5 - 2$ </h3><h3>(Note: there's many ways to solve these types of equations, I just gave you the basic method) </h3><h3 /><h3>Good luck on your assignment and enjoy your day! </h3><h3>~ $LoveYourselfFirst:)$ </h3>

HELP someone please!!!! i dont understand

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
