If she saves 1$ the first week 3$ the season week 9$ the third week how much will she save in 5 weeks
ycow [4]

Based on the numbers we have we can assume that she saves 3 times more each week than the last (1*3=3, 3*3=9).

Following this trend we would multiply the amount she saved the third week ($9) by 3 to get $27 for the fourth week.

Then, we would multiply the amount she saved the fourth week ($27) by 3 to get $81 for the fifth week.

Finally, to figure out how much she saved in the 5 weeks, we need to add each value up to get 1+3+9+27+81= $121 saved in 5 weeks

If the farmer has 250 feet of fencing to create a rectangular pen, define a function f that expresses the area of the field (mea
hoa [83]

Answer:

Maximum area possible

f(max)  = 3906,25 ft²

Dimensions:

a  = 62,5  ft

w  = 62,5 ft

Step-by-step explanation:

Perimeter of the rectangular fencing    P  =  250 feet

And sides of the rectangle  a  and  w (width of rectangle)

Then

A =  a*w

2a  + 2w  = 250       ⇒  a  =  (250 -2w)/ 2    ⇒  a = 125 - w

f(w)  =  (125  - w ) *w        f(w)  = 125w - w²  

Taking derivatives both sides of the equation

f´(w)   =  125  - 2w              f´(w)   = 0           125  - 2w = 0

w = 125/2

w = 62,5 ft            ⇒  a = 125 - 62,5

a = 62,5 ft

f(max)  = ( 62,5)²

f(max)  = 3906,25 ft²

Alice planted some corn in the back yard and measures it’s height regularly. The last time she checked, the stalks were 60 inche
sdas [7]

Answer:

The percent of increase in height of the stalks is 20%.

Step-by-step explanation:

The general formula for a percent increase is as follows:  (Original Amount - New Amount/Original Amount) x 100.  The original height of the stalks was 60 inches tall.  The new height of the stalks is 72 inches.  In the numerator of our fraction, we take 72-60 to get 12.  Our denominator is the original amount, or 60.  This gives us an overall fraction of 12/60, which when we divide gives us 0.2.  Once we multiply our decimal by 100, we get an overall percent increase of 20%.

The sum of five different positive integers is 320. The sum of the greatest three integers in this set is 283. The sum of the gr
Nina [5.8K]

Answer:

17

Step-by-step explanation:

Let a,b,c,d,x represent the five integers in Ascending order.

Given;

The sum of five different positive integers is 320

a+b+c+d+x = 320 .......1

The sum of the greatest three integers in this set is 283

c+d+x = 283 .....2

The sum of the greatest and least integers is 119

a+x = 119 ......3

For the largest possible value;

From equation 3, if a is as low as 1,

x = 119-1 = 118

x = 118

For the least possible value;

Subtract equation 2 from 1

a+b = 320-283 = 37

We know that a cannot be higher than b, so the highest possible value of a is;

a = 37-b

a = 37- 19 = 37-19

a = 18

Substituting into equation 3

x = 119-18 = 101

Difference;

∆x = 118-101 = 17
