Step-by-step explanation:

A. Varkala is the best choice as it ticks both the categories. It is a laid-back getaway with cliffs fronting a turbulent sea, a lineup of coconut groves, regular yoga session planned by the hotels and resorts, cafes serving the fresh catch of the day, afforded by the setting are several Ayurveda clinics and resorts that specialise in Ayurvedic therapies complete with their resident doctors and nutritionists.

Answer:  Choice B) 60 roses and 10 carnations

============================================================

Explanation:

  • r = number of roses
  • c = number of carnations

r and c are positive whole numbers.

r+c = total number of flowers = 50, since 50 orders are made.

The first equation to set up is r+c = 50.

This equation can be solved to get r = 50-c.

------------------

3r = cost of all the roses only, in dollars

1.5c = cost of all the carnations only, in dollars

3r+1.5c = total cost of all the flowers = 195 dollars

3r+1.5c = 195

------------------

Let's apply substitution to solve

3r+1.5c = 195

3(50-c)+1.5c = 195

150-3c+1.5c = 195

-1.5c+150 = 195

-1.5c = 195-150

-1.5c = 45

c = 45/(-1.5)

c = -30

That's not good. We shouldn't get a negative value.

It turns out that the condition r+c = 50 should be ignored. Notice how none of the answer choices listed have r+c leading to 50.

So we'll only focus on the equation 3r+1.5c = 195

-----------------

If we plugged in r = 100 and c = 100, then we get

3r+1.5c = 195

3(100)+1.5(100) = 195

300+150 = 195

450 = 195

Which is false. So we can rule out choice A

Let's repeat those steps for choice B

3r+1.5c = 195

3(60)+1.5(10) = 195

180 + 15 = 195

195 = 195

So that works out. I have a feeling your teacher meant to say "70 orders" instead of "50 orders". If so, then the equation r+c = 50 would be r+c = 70 and everything would lead to choice B as the final answer.

Choices C and D are similar to that of choice A, so they can be ruled out.

Help me with this math problem??
vlabodo [156]

Answer:

B; 4.5 meters.

Step-by-step explanation:

Analyzing the question, we can see that 1 cm is equivalent to 1.5 meters.

Therefore, we must multiply 1.5 * 3 because the height of the sailboat in her drawing is 3 cm, and will be multiplied by 1.5 meters to find the real height.

1.5 * 3 = 4.5

Thusly, the height, in meters, of the actual boat is \boxed{{4.5\text{\:meters\:or\:B}}}.

Hope this helps! (:

What is the answer to the jones family plans a trip to the amusement park...
Levart [38]
The answer would be C: 128+8.50x+9.50y+10z.

This is because all of the costs of the different items will add up depending on how much of them the family buys. This is why they all have the corresponding variables next to the prices. The prices of those items will be added on to the initial cost of the 128$ family package, so all of the prices would be added up together to get the total.
