Molly wishes to make a lawn ornament in the form of a solid sphere. the clay being used to make the sphere weighs .075 pound per
weeeeeb [17]
The first thing we must do for this case is find the volume of the sphere.
 The volume is given by:
 V = (4/3) * (pi) * (r ^ 3)
 Where,
 A: Radius of the sphere
 Substituting values:
 V = (4/3) * (3.14) * (4 ^ 3)
 V = 267.95 in ^ 3
 Then, the weight of the sphere is:
 W = (267.95) * (0.75)
 W = 200.9625 pounds
 Round to the nearest pound:
 W = 201 pounds
 Answer:
 T
he weight of the sphere is:
 
W = 201 pounds

\rule{70mm}{2.9pt}

\large \sf{✟ \: Problem \: ✟} :

An airplane is flying at a height of 5 kilometers above the ground. The distance along the ground from the airplane to the airport is 7 kilometers. What is the angle of depression from the airplane to the airport? (Write the answer to the nearest degree.)

\rule{70mm}{2.9pt}

\large \sf{✟ \: Solution \: ✟} :

✞ Step 1 ✞: Identify what is asked in the problem.

❒ The angle of depression from the airplane to the airport.

✞ Step 2 ✞: Use appropriate trigonometric ratio to solve the problem.

❒ Since the two legs of the right triangle are part of the problem, hence we use tangent ratio:

\qquad \qquad \bigstar \:  \: \boxed{\tt{ \quad \tan A \degree =  \frac{5}{7}  \quad}}

✞ Step 3 ✞: Solution and interpretation.

:  \qquad \large \implies \tt{ \tan A =  \frac{5}{7} }

:  \qquad \large \implies \tt{A =   \tan^{ - 1}(\frac{5}{7} )}

:  \qquad \large \implies \tt{A =  35.54 \approx \pmb{36 \degree}}

\rule{70mm}{2.9pt}

\large \sf{✟ \: Answer \: ✟} :

Hence, the angle of depression from the airplane to the airport is approximately 36°.

QUESTION: 1 1/5 = -2 2/3 x +6<br> solve for x will give brainliest answer quickly or no brainliest.
Whitepunk [10]

Answer: x=1\frac{4}{5}

<u>Simplify both sides of the equation</u>

<u></u>\frac{6}{5} =\frac{-8}{3} x+6<u></u>

<u></u>

<u>Flip the equation</u>

<u></u>\frac{-8}{3} x+6=\frac{6}{5}<u></u>

<u></u>

<u>Subtract 6 from both sides</u>

<u></u>\frac{-8}{3} x+6-6=\frac{6}{5} -6<u></u>

<u></u>\frac{-8}{3} x=\frac{-24}{5}<u></u>

<u></u>

<u>Multiply both sides by 3/(-8)</u>

<u></u>(\frac{3}{-8} )*\frac{-8}{3} x)=(\frac{3}{-8} )*(\frac{-24}{5} )<u></u>

<u></u>x=\frac{9}{5}<u></u>

<u></u>

<u>Turn 9/5 into a Mixed Number</u>

<u></u>x=\frac{9}{5} =1\frac{4}{5} \\x=1\frac{4}{5}<u></u>
