Solve for f. d = 16ef² f=±4de‾‾‾√ f=±4de√e f=±de√4e f=±de√16
matrenka [14]

Answer:

The value of f out of given expression d=16ef^2 is \frac{\pm 1}{4}\sqrt{\frac{d}{e}}

Step-by-step explanation:

Given : expression d=16ef^2

We have to solve for f.

Consider the given expression  d=16ef^2

Divide both side by 16e, we get,

\frac{d}{16e}=f^2

Now, taking square root, both sides, we have,

\sqrt{\frac{d}{16e}}=\sqrt{f^2}

Simplify, we get,

\sqrt{\frac{d}{16e}}=f

We know \sqrt{16}=\pm 4 , we get,

\frac{\pm 1}{4}\sqrt{\frac{d}{e}}=f

Thus, The value of f out of given expression d=16ef^2 is \frac{\pm 1}{4}\sqrt{\frac{d}{e}}

Company A offers a weekly salary of $360 plus a commission of 18% on thier dollar sales volume. Company B offers a weekly salary
Lera25 [3.4K]

Answer: The dollar sales volume will be $4000

Step-by-step explanation:

Let x represent the amount of sales volume for which the two offers result in the same pay.

Company A offers a weekly salary of $360 plus a commission of 18% on their dollar sales volume. This means that the total value offered by company A for x sales volume is

360 + 0.18x

Company B offers a weekly salary of $720 plus commission of 9% on their dollar sales volume. This means that the total value offered by company B for x sales volume is

720 + 0.09x

For the two offers to be the same, the sales volume would be

360 + 0.18x = 720 + 0.09x

0.18x - 0.09x = 720 - 360

0.09x = 360

x = 360/0.09

x = $4000

A 2​-ft vertical post casts a 20​-in shadow at the same time a nearby cell phone tower casts a 125​-ft shadow. How tall is the c
chubhunter [2.5K]

Answer:

1249. 5 inches

Step-by-step explanation:

Pole length , Pl = 2 fts

Pole shadow, Ps = 20 in = (0.0833 * 20) = 1.666 ft

Tower length, Tl = 125 ft

Tower shadow, Ts = x

Pl / Ps = Tl/ Ts

2/ 1.666 = 125 / x

Cross multiply

2x = 125 * 1.666

2x = 208.25

x = 104.125 ft

x = 104.125 * 12 = 1249. 5 inches
