Answer:

Weekly Expense=$234

Required Quantity of Sales to Cover Weekly expenses=32.5 kg

Step-by-step explanation:

Sales Price per kilogram =$7.20

Quantity of sales = 90 kg

Weekly Total Sales = $7.20 X 90 =$648

Weekly Profit=$414

Therefore her Weekly Expense= Weekly Total Sale- Weekly Profit=648-414=$234

Since 1 kg costs $7.20, to cover her weekly expenses she has to sell:

$234/7.20 = 32.5 kg

kumpel [21]

Answer:

The correct answer is diagonals are equal and bisect each other.

Step-by-step explanation:

A rectangle is a quadrilateral with opposites sides equal in length and all interior angles equal to 90°. Opposite sides are parallel and adjacent sides are perpendicular. Diagonals in a rectangle are equal in length and they bisect each other. If we want to draw a circumcircle, then the point of intersection of these diagonals give the circumcenter.

Lin read for x minutes, and Elena read for more than that. Write an expression for the number of minutes Elena read. Only use de
Vikentia [17]
<h2>Explanation:</h2><h2 />

In this exercise, we know some facts:

  • Lin read for x minutes.
  • Elena read for more than that.

The problem tells us nothing about the number of minutes Elena read more than Lin. However, let's say Elena read one-third more than the number of minutes Lin read. Therefore:

<u>For Lin:</u>

Number \ of \ minutes \ Lin \ read=x

<u>For Elena:</u>

Number \ of \ minutes \ Elena \ read=x+\frac{1}{3}x \\ \\ Number \ of \ minutes \ Elena \ read=\frac{3x+x}{3} \\ \\ Number \ of \ minutes \ Elena \ read=\frac{4x}{3} \\ \\ Number \ of \ minutes \ Elena \ read=\frac{4x}{3} \\ \\ \\ By \ using \ decimals: \\ \\ Number \ of \ minutes \ Elena \ read \approx 1.33x

Computing if a computer can do one calculation in 0.0000000015 second, then the function t(n) = 0.0000000015n gives the time req
Lelechka [254]

Answer:

t(5,000,000,000) = 7.5 sec

Explanation:

A computer take 0.0000000015 sec to do a calculation.

Given a function t(n) = 0.0000000015n

where n represent the number of calculation.

We need to find the total time computer to do 5 billion calculations.

We plug n = 5 billion = 5,000,000,000

Total taken time t(n) =0.0000000015n

t(5,000,000,000) = (0.0000000015)*(5,000,000,000)

t(5,000,000,000) = 1.5*5

t(5,000,000,000) = 7.5 sec

That's the final answer.

I hope it will help you.
