Angelica is a sales representative for appliance. She needs to make at least $5,000 in weekly sales of a particular TV model to
Basile [38]

Answer:

20 TV need to be sold to qualify for the trip.

Step-by-step explanation:

Given: Sale price of each TV is $250

           Sales target to qualify for trip is $5000.

As given, T represent TV sold.

Now, finding the number of TV sold to qualify for the trip.

Forming an inequality for the number of TV sold to qualify for trip.

We know, Total amount of TV sold= Selling\ price\ of\ each\ TV \times Number\ of\ TV\ sold

∴ To qualify for trip: 250T\geq 5000

solving it by dividing both side by 250

∴T\geq \frac{5000}{250}

T\geq 20\ TV

Hence, Angelica need to sell minimum 20 TV to qualify for the trip.

Answer:

CD = 6.385 units

Step-by-step explanation:

Given triangle ABC with right angle at C.

And AB = AD + 6 .

Now, consider the triangle ABC.

⇒ cos(∠BAC) = \frac{AC}{AB}  (cosФ = adj/hyp)

cos(20) = \frac{AC}{AB} .

0.9397 = \frac{AD+CD}{AD + 6}

(since AB = AD + 6 and AC = AD + CD)

⇒ 0.9397 AD + 5.6382 = AD + CD

⇒ CD = 0.0603 AD + 5.6382. →→→→→ (1)

⇒ sin(∠BAC) =  \frac{BC}{AB} (sinФ = opp/hyp)

sin(20) =  \frac{BC}{AB}.

⇒ BC = AB sin(20)  . →→→→→(2)

Now, consider the triangle BCD,

sin(∠BDC) =  \frac{BC}{CD}

⇒ sin(80) =  \frac{BC}{CD}

CD =  \frac{BC}{sin(80)}

From (2), CD = \frac{AB sin(20)}{sin(80)} .

⇒ CD = AB (0.3473)

⇒ CD = (AD + 6) (0.3473)

⇒ CD = 0.3473 AD + 2.0838 →→→→→→(3)

Now, (1) →→ CD = 0.0603 AD + 5.6382

         (3) →→ CD = 0.3473 AD + 2.0838

⇒ 0.0603 AD + 5.6382 = 0.3473 AD + 2.0838

0.287 AD = 3.5544.

⇒ AD = 12.3847

⇒ From (1), CD = 0.0603(12.3847) + 5.6382

⇒ CD = 6.385 units

Find the slope of the line y=-8x
Makovka662 [10]

Answer:

slope (m) = -8.

Step-by-step explanation:

Slope-intercept form is y = mx + b, in which:

m = slope

b = y-intercept

x = (x , y)

y = (x , y)

~

With the given information on top, it means that -8 is your answer.
