Soup ordinarily priced at 2 cans for .33 cents may be purchased in lots of one dozen for 1.74, what is the savings per a can whe

Sidana [21]

Answer:

Savings per can would be 0.02 cents when purchased in lots.

Step-by-step explanation:

Given:

Ordinary price of soup 2 cans = 0.33 cents.

When purchases in lots 12 cans = 1.74

We need to find the saving per can when purchased in Lots.

Solution:

Ordinary price of soup 2 cans = 0.33 cents.

1 can = Cost of 1 can when purchased ordinary.

By Using Unitary method we get;

Cost of 1 can when purchased ordinary = $\frac{0.33}{2} = 0.165\ cents/can$

Now we will find the Cost of 1 can when purchased in lot.

12 cans = 1.74

1 can = Cost of 1 can when purchase in lot.

Again by using Unitary method we get;

Cost of 1 can when purchase in lot = $\frac{1.74}{12} = 0.145\ cents/can$

Savings = Cost of 1 can when purchase in lot - Cost of 1 can when purchased ordinary

Savings = $0.165-0.145=0.02\ cents/can$

Hence Savings per can would be 0.02 cents when purchased in lots.

What value for c will make the expression a perfect square trinomial? x2 – 7x + c negative StartFraction 49 Over 4 EndFraction n

puteri [66]

Answer: $c=\frac{49}{4}$

Step-by-step explanation:

You can find the value of "c" that will make it a perfect square trinomial by Completing the square.

Given the following expression provided in the exercise:

$x^2 - 7x + c$

You can notice that it is written in this form:

$ax^2-bx+c$

Then, you can identify that the coefficient "b" is:

$b=-7$

Since to complete the square you must add and subtract the half of square of coefficient "b", you can conclude that:

$c=(\frac{b}{2})^2$

Therefore, substituting "b" into $c=(\frac{b}{2})^2$ , you get:

$c=(\frac{-7}{2})^2\\\\c=\frac{49}{4}$

Calvin deposits $400 in a savings account that accrues 5% interest compounded monthly. after c years, calvin has $658.80. makayl

vodomira [7]

You will need a special formula to compute this.
Years = log (total/principal) / [n * log * (1 + rate / n)]

Part A) Calvin $400 5% monthly 658.80 Time = ?
Monthly compounding "n" = 12
Years = log(658.80/400) / [12 * log(1+ (.05/n))
Years = log ( 1.647 ) / (12 * log ( 1.0041666667 )
Years = 0.21669359917 / 12 * 0.0018058008777
Years = 0.21669359917 / 0.0216696105 
Years = 9.999884362 


Part B) Makayla 300 6% quarterly 613.04Time=?
Quarterly compounding
n = 4
Years = log (total/principal) / [n * log * (1 + rate / n)]
Years = log (613.04/300) / [4 * log (1 + .06/4)]
Years = log ( 2.0434666667 ) / 4 * log (1.015)
Years = 0.31036755784 / 4 * 0.0064660422492
Years = 0.31036755784 / 0.025864169 
Years = 11.9999044949 

So, the difference is roughly 3 years.

Level curves for barometric pressure (in millibars) are shown for 6:00 AM on November 10, 1998. A deep low with pressure 972 mb

Ronch [10]

Answer: the value of the directional derivative of the pressure function at Kearney in the direction of Sioux City is - 0.09 mb/km

Step-by-step explanation:

lets make an assumption that P is the pressure of the function

Now to estimate the value of the directional derivative of the pressure function at Kearney in the direction of Sioux City wil be DuP

The initial point of the line joining the point of kearney and sioux lays on the level curve which represent 1000mb of pressure

and the terminal point of the line joining the point of kearney and sioux lays on the level curve which represent 972 mb of pressure

so let our X1 = 1000 mb

X2 = 972 mb

the given distance between kearney and sioux d = 300 km

so the directional derivative DuP at Kearney in the direction of Sioux City is approximated by finding the average rate change of the pressure between the points

so DuP = (X2 - X1) / d

= (972 - 1000) / 300

= -28 / 300

= - 0.09 mb/km

Therefore the value of the directional derivative of the pressure function at Kearney in the direction of Sioux City is - 0.09 mb/km
