Answer:
Las dimensiones del rectángulo son:
ancho = 16 cm
largo = 20 cm
Step-by-step explanation:
Consideración:
La formula del perímetro de un rectángulo es:
perímetro = 2(largo + ancho)
25% más grande = 125% = 125/100 = 1.25
Planteamiento:
2(a+b) = 72
b = 1.25a
a = longitud del ancho
b = longitud del largo
Desarrollo:
de la primer ecuación del planteamiento:
a+b = 72/2
a+b = 36
b = 36 - a Ec. 3
Igualando la segunda ecuación del planteamiento con la Ec. 3:
1.25a = 36 - a
1.25a + a = 36
2.25 a = 36
a = 36/2.25
a = 16
de la Ec. 3:
b = 36 - a
b = 36 - 16
b = 20
Comprobación:
de la primera ecuación del planteamiento:
2(a+b) = 72
2(16+20) = 72
2*36 = 72
1. C. -512√3+512i
2. B. 16(cos240°+i sin240°)
3. D. 3√2+3√6i, -3√2-3√6i
4. A. cos60°+i sin60°, cos180°+i sin180°, cos300°+i sin300°
5. D. 2√3(cos π/6+i sin π/6), 2√3(cos 7π/6+i sin 7π/6)
1. A real world scenario could look something like this:
A ladder is resting against a straight wall. The distance from the top of the ladder to the bottom of the wall is 8m, while the distance from the base of the wall to the foot of the ladder is 6m. Find the length of the ladder.
2.That is the diagram for the real life example
3. Use pythagoras theorem to solve it
6^2+8^2=x^2
100=x^2
x=10
So the ladder is 10 m
Answer:
Step-by-step explanation:
To find the product of two matrices we need to multiply the elements of each row of the first matrix by the elements of each column in the second matrix. Then we should add the products. Then:
× = =
The term "x" refers to the multiplication sign.
Then, the solution is
Answer: Wouldn't that make it x=44
Step-by-step explanation:
I just divided 176 by 4 because it said the value of y varies directly with x. So just used the rule they used i guess.
