In TVW if VW is three meters longer than TV, TW is 20 meters shorter than the sum of VW and TV, and the perimeter of TVW is 74 m

Artyom0805 [142]

Answer:

The length of VW is $25\ m$

Step-by-step explanation:

we know that

The perimeter of triangle TVW is equal to

$P=VW+TV+TW$

we have

$P=74\ m$

so

$74=VW+TV+TW$ -----> equation A

$VW=TV+3$ ----> equation B

$TW=(VW+TV)-20$ ----> equation C

substitute equation B in equation C

$TW=(TV+3+TV)-20$

$TW=2TV-17$ ----> equation D

substitute equation B and equation D in equation A

$74=(TV+3)+TV+(2TV-17)$

solve for TV

$74=4TV-14$

$4TV=74+14$

$4TV=88$

$TV=22\ m$

Find the value of VW

$VW=TV+3$ -----> $VW=22+3=25\ m$

Find the value of TW

$TW=2TV-17$ -----> $TW=2(22)-17=27\ m$

1. (10pts] Let A = {1, 2, 3, 4, 5}, let B = {1,4,5,7,8,9}, and let C = {2, 4, 6, 7,9}. Determine each of the following (a) An Bn

alisha [4.7K]

Answer and explanation:

Given : Let A = {1, 2, 3, 4, 5}, let B = {1,4,5,7,8,9}, and let C = {2, 4, 6, 7,9}.

To find : Determine each of the following,

a) $(A\cap B)\cap C$

b) $(A\cup B)\cap (A\cup C)$

c) $A - (B\cup C)$

d) $(A-C) (C-A)$

Solution :

The union of two sets is a new set that contains all of the elements that are in at least one of the two sets.

The intersection of two sets is a new set that contains all of the elements that are in both sets.

a) $(A\cap B)\cap C$

$A\cap B=\{1,4,5\}$

Then, $(A\cap B)\cap C=\{4\}$

b) $(A\cup B)\cap (A\cup C)$

$A\cup B=\{1,2,3,4,5,7,8,9\}$

$A\cup C=\{1,2,3,4,5,7,9\}$

$(A\cup B)\cap (A\cup C)=\{1,2,3,4,5,7,9\}$

c) $A - (B\cup C)$

$B\cup C=\{1,2,4,5,6,7,8,9\}$

$A - (B\cup C)=\{3\}$

d) $(A-C) (C-A)$

$A-C=\{1,3,5\}$

$C-A=\{6,7,9\}$

$(A-C) (C-A)=\{1,3,5\}\times\{6,7,9\}$

$(A-C) (C-A)=\{(1,6),(1,7),(1,9),(3,6),(3,7),(3,9),(5,6),(5,7),(5,9)\}$

PLSSSSSSS HELPPPPPppppp

icang [17]

Answer:

20 units

Step-by-step explanation:

The polygon has 4 vertices as indicated by the 4 coordinate points given.

(3, 1) and (8, 1) is a horizontal side of length 8 - 3 = 5

Similarly

(3, 6) and (8, 6) is the opposite horizontal side of length 8 - 3 = 5

Points (3, 1) and (3, 6) is a vertical side of length 6 - 1 = 5

(8, 1) and (8, 6) is the opposite side of length 6 - 1 = 5

The polygon is therefore a square of side 5 units.

Perimeter = 4 × 5 = 20 units
