Answer:
Perímetro = 8.925 metros
Step-by-step explanation:
La formula del perímetro de un rectángulo es:
perímetro = 2(ancho + largo)
en este caso:
p = 2(a+b)
a = 3b/4
b = 2.55m
a = ancho del rectángulo
b = largo del rectángulo
entonces:
sustituyendo el valor de la segunda ecuación
p = 2((3b/4)+b)
p = 2((3b/4)+(4b/4))
p = 2(7b/4)
p = 14b/4
p = 7b/2
p = 7*2.55/2
p = 8.925m
Answer:
-4.6, -4 1/9, 4.2, 4.6
Step-by-step explanation:
What I like to do is convert everything into either decimal form. This makes ordering a lot easier.
This will leave you with:
4.2
-4.11
-4.6
4.38
Negative numbers are lower than positive ones, so they will come first.
Answer:
Step-by-step explanation:
150/360=5/12 so the sector is 5/12 the area of the whole circle which is 81π. 5/12(81π) =405/12 or 135/4. Answer A
<h3>
Answer: 6x - 3</h3>
Work Shown:
y = expression for the missing side
perimeter = 9x - 1
side1+side2+side3 = perimeter
(2x+4) + (x-2) + (y) = 9x - 1
3x+2 +y = 9x-1
y = 9x-1-3x-2
y = 6x - 3
Assuming you're asking for the area and the length is 52 ft...
52 x 9 = 468
Area; 468 ft squared
