6 0

Answer:

  89.6 square feet

Step-by-step explanation:

The total area is that of a 5×14 rectangle and a circle with a radius of 2.5 feet:

  A = bh +πr^2

  = (5 ft)(17 f) +π(2.5 ft)^2

  = 70 ft^2 + 6.25π ft^2

  ≈ (70 +19.6) ft^2 = 89.6 ft^2

The approximate area is 89.6 square feet.

To answer this question, we have the start-up costs of $ 52,000

A monthly inflation of $ 0 is assumed

Operating costs  are $680

The daily gain  is $960

For the Part A.

The inequality that this situation represents

 960d-680d>52000

So:

d(960-680)>52000

Where d represents the number of days.

For the Part B.

To start earning, you must replace all the initial investment and cover the expenses per day. The time that must pass for this to happen is obtained by clearing "d" from the inequality.


 d>\frac{52000}{960-680}

d> 185.71 days

Then, the sum of the net profits will be greater than the initial investment after 186 days of starting the business.

Find the value of x and y. y=2x and 1.85x+3.7y=12.95
Len [333]

Answer:

x=1.4 y=2.8

Step-by-step explanation:

Lets substitute y with 2x. We get: 1.85x+7.4x=12.95.

Simplifying by combining x: 9.25x=12.95

Then you just divide 12.95 by 9.25: x=1.4

Now for y. We know why is 2x so we just have to multiply x by 2: y=2x, y=2.8.
