worty [1.4K]
I think buying 36 ears of corn for $7.20 is the better buy. 6 ears of corn for $1.25 cost .20+ per ear of corn. Buying the 36 count buys them at an even .20. Plus he should have enough for everybody without having to worry about buying more.

The answer came from Rgwoot Ambitious

from another post in case anyone else needs it

What we know:

shape is rectangle which means the 2 long sides have equal distance and the 2 short sides have equal distance

we just need to find the distance of one long side and one short side for the perimeter which is the outline of the rectangle. Imagine the perimeter is the fence around the rectangle  that you would probably have to paint every 3 years and the area would be where the grass would grow in the rectangle which you would probably have to cut every weekend.


perimeter=2l+2w

 

What we need to find: PERIMETER

Using pythagorean method a² +b²=h² to find length:

From point (-6,1) to point (3,8) is a rise of 9 and a run of 9 right to get from one point to another, those are my a and b in the pythagorean formula.

a² +b²=h²

(9)²+(9)²=h²         substitution

81+81=h²            simplified

162=h²

√162=√h2           used radical properties

√162=h               length =√162


Using pythagorean method a² +b²=h² to find width:

From points (-6,-1) to point (-3,-4) is a down 3 units and left 3 units to reach from one point to another, these are my a and b for the pythagorean formula.


a² +b²=h²

(3)²+(3)²=h²

9+9=h²

18=h²

√18=√h²

√18=h           this is the width=√18


Now we find perimeter:

p=2l+2w

p=2(√162)+2(√18)

p≈33.9


D. 33.9 units

How do you do this? Explain
Alisiya [41]

Answer:

D

Step-by-step explanation:

This is because when making a triangle, the two shortest sides have to add up to be bigger than the biggest side. For example, A would work because if you did 4+6, it would equal 10 which is bigger than the biggest side. B and C add up to something bigger than 6. However, D is different. If you do 2+4, that equals 6. It has to be bigger than six, not equal

f  = 3.1

Step-by-step explanation:

First you must subtract 6.4 from both sides to get -4.8f = -14.88. Divide both sides by -4.8 to get f = 3.1
