The telephone company offers two billing plans for local calls. Plan 1 charges $ per month for unlimited calls and Plan 2 charg

Brums [2.3K]

Answer and Step-by-step explanation:

Let us assume the number of calls be x

For Plan 1

Total monthly charges is $24 for unlimited calls

For Plan 2

There is a charge of $16 and $0.04 per call

We can write as

= 0.04x + $16

a) Now the inequality equation is

0.04x + $16 > $24

0.04x > $8

x > 200

b) Now if there are more than 200 calls than Plan 1 is more economical as compared with plan 2

To control an infection, a doctor recommends that a patient who weighs 92 pounds be given 320 milligrams of antibiotic. If the a

Answer: 480 milligrams

Step-by-step explanation:

We can solve this by using direct proportion whereby y = kx

where,

x = patient's weight = 92 pounds

k = constant

y = milligrams of antibiotics = 320

Using y = kx

320 = 92k

k = 320/92

k = 3.4782609

The antibiotic that should be given to a patient who weighs 138 pounds will be:

y = kx

y = 3.4782609 × 138

y = 480 milligrams

The antibiotic that should be given to a patient who weighs 138 pounds is 480 milligrams.

Find the value of tan F rounded to the nearest hundredth , if necessary

spin [16.1K]

Using it's formula, it is found that the tangent of F is given by:

$\tan{F} = \frac{6\sqrt{85}}{85}$

<h3>How to find the tangent of an angle?</h3>

In a right triangle, the tangent of an angle is given by the length of the opposite leg divided by the length of the adjacent leg.

Researching the problem in the internet, it is found that for the <em>right triangle</em> in this problem:

The length of the opposite leg to angle F is of 6.

The length of the adjacent leg to angle F is of x.

The length of the hypotenuse is of 11.

Applying the Pythagorean Theorem, we have that:

$6^2 + x^2 = 11^2$

$36 + x^2 = 121$

$x^2 = 85$

$x = \sqrt{85}$

Considering that the tangent is the length of the opposite leg divided by the length of the adjacent leg, we have that:

$\tan{F} = \frac{6}{\sqrt{85}} \times \frac{\sqrt{85}}{\sqrt{85}} = \frac{6\sqrt{85}}{85}$
