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:
The weight of the sphere is:
W = 201 pounds

$\large \sf{✟ \: Problem \: ✟} :$

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>
