Find the perimeter of the triangle shown using the Associative proprety. 4 1/2 in 5 1/2in 6 in

Answers

Answer 1
Answer: so assumn that the measures given are the legnths of the sides
perimiter=side1+side2+side3
so
side1=4 and 1/2
side2=5 and 1/2
side3=6
subsitute
p=(4+1/2)+(5+1/2)+(6)
associative prpoerty says (a+b)+c=a+(b+c) (it deals with addiont with parenthasees)
p=4+1/2+5+1/2+6
p=4+5+1/2+1/2+6
p=9+1+6
p=10+6
p=16 inches

Answers

rectanglearea=legnth timees width
triagnlearea=1/2base times height

ok so we find volume of entier land first

we can cut into triangle an rectangle

triangle=height=650-200=450
base=600
area=1/2*600*450=135000 ft^2

rectangle=200 times 600=120000

add
135000+120000=255000ft^2


find other areas and subtract
areahouse=45*38=1710
areawooded=118*60=7080
frontyard=78*40=3120
add
1710+7080+3120=11910

minus

255000-11910=243090

how many acres are farmed

43560ft^2=1acre
divide both sides by 43560
1ft^2=1/43560 acre

multiply both sides by 243090
243090ft^2=243090/43560acre=5.5805acre=5.6acre rounded

answer is 5.6 acer


On a 1/5 scale drawing of a car, one part is 8 inches long. How long will the actual car part be?

Answers

If it's one fifth scale, take it times five to get the whole scale. 8 times five equals 40. The car is 40" long, 3' 4" long, or three and one third feet long.

Answer:

The actual length of the given car part is 40 inches.

Step-by-step explanation:

Given : Scale of drawing of a car is (1)/(5)

Also, given one part is 8 inches long.

We have to find the actual length of the given car part.

Since, the given scale decreases the actual length by a factor of (1)/(5)

So, The actual length will be

New length = (1)/(5) × actual length

Thus, Actual length will be

Actual length = 5 ×  new  length

 Actual length = 5 × 8 = 40 inches.

So,  The actual length of the given car part is 40 inches.

Which relation is a function?

Answers

As given in the question,

the relations A , B ,C and D are set up as a table of ordered pairs.

We now test to see if each element in the domain(x-values) is matched with exactly one element in the range(y-values). If so, you have a function!

A is not a function as the domain value 0 is paired with both 3 and 4.

B is a function as for each input there is exactly one output.

C is not a function as the domain value 2 is paired with both 1 and 8.

A is not a function as the domain value 1 is paired with both -3 and 2.
