The farmer decided that he ordered enough planks for an arena that measured 115 1/4 ft by 63 1/2 ft. Is he correct? Explain.

Mars2501 [29]

Answer:

<h2>The question we need to answer is what is the perimeter of the arena</h2>

Step-by-step explanation:

The question we need to answer is what total length of plank did the farmer ordered for the arena.

to solve for the length of plank to cover the arena we need to solve for the perimeter of the arena.

given data

length L= 115 1/4 ft = 115.25ft

width W= 63 1/2 = 63.5ft

perimeter= 2L+2W

perimeter= 2(115.25)+2(63.5)

perimeter= 230.5+127

perimeter= 357.5ft

This means that the farmer ordered a total length of 357.5ft of plank

Let a be the vector of length 125 that when drawn in standard position makes a 144° angle with the positive x-axis. Let b be the

umka2103 [35]

Answer:

The length is 90.033 and the angle that v makes with the positive x-axis is 153.339°

Step-by-step explanation:

Firstly we will have to convert our given vectors to their rectangular Cartesian vector form as follow,

$a=125(icos(144)+jsin(144))=-101.127i+73.473j\\b=39(icos(302)+jsin(302))=20.667i-33.074j$

Now that we have these, we can add them to obtain v as follows,

$v=a+b\\v=-80.46i+40.399j$

Now that we have the Cartesian vector form we can calculate its length and its direction with respect to the positive x-axis as follows(In fact we usually refer the angles from the positive x-axis),

$|v|=\sqrt{80.46^{2}+40.399^{2}}=90.033\\ angle(v)=tan^{-1}(40.399/(-80.46))=153.339$

So the length of the vector is 90.033 and the angle it makes with the positive x-axis is 153.339°.

Answer:

6x+48+15+3x and 9x+63

Step-by-step explanation:

3(2x+16)=6x+48 and 3(5+x)=15+3x. 6x+48+15+3x=9x+63 .
