Answer:

The equation can be expressed as;

x+y=71 where,

Lengths of two equal sides=x=22 m

Lengths of longer side=y=27 m

Step-by-step explanation:

The total perimeter can be expressed as;

Total perimeter=Total length of the equal sides+total length of the longer side

where;

Total perimeter=71 m

Total length of each of the equal sides=x m

Total length of longer side=y=(x+5) m

replacing;

x+y=71...equation 1

71=(2×x)+(x+5)

2 x+x=71-5

3 x=66

x=66/3

x=22 m

y=x+5=22+5=27 m

Lengths of two equal sides=22 m

Lengths of longer side=27 m

Equation;

x+y=71

Answer:

∡SYZ = 34.2°

∡XYZ = 68.4°

Step-by-step explanation:

∡SYZ = 34.2°  this must be true because this angle is congruent to ∡XYS

∡XYZ = 68.4°  this must be true because ∡XYZ = ∡WYS + ∡SYZ

The perimeter of a quarter circle is 14.28 KM. What is the quarter circle's radius?
lawyer [7]
Circumference= 2πr
Circumference= perimeter

14.28km= 2(3.14)r
14.28= 6.2831853072r
divide both sides by 6.2831853072
2.27= r

ANSWER: The radius is 2.27km

Hope this helps! :)

Maximize Q=3xy^2, where x and y are positive numbers such that x+y^2=2
Ivanshal [37]
Sub x = 2-y^2 to Q, we get:
Q = 3(2-y^2)*y^2
let y^2 = k
Q = 3(2-k)k = 3(2k-k^2)
2k-k^2 has a max when k = 1
Then y^2 = 1 -> y = 1 or -1

1) It's best to draw out a picture of a rectangle and label each corner with the coordinates given: Let's say (-5, 2) is point A, (-5, -2 1/3) is point B, (2 1/2, 2) is point C, and (2 1/2, -2 1/3) is point D.

2) That being said, line AB is one side of the rectangle, BC is another, CD is another, and lastly, AD is the fourth side.

3) We can use the distance formula and plug in the coordinates of each line to find how long every side is. Then you just need to solve it.

For example: if I want to find how long side AB is, I would use the point A (-5, 2) and B (2 1/2, 2) and plug them into the distance formula, where (-5, 2) is (x1, x2) and (2 1/2, 2) is (x2, y2) and solve that.

4) Repeat this process with side BC, CD, and AD, and add the results together. This will be your final answer; the perimeter of the rectangle.
