Answer:
Therefore,
Step-by-step explanation:
Simplify
-2^3
It is read as negative 2 raised to the power three,
also it is the cube of negative 2
we know that given as
so for negative a i.e -a
substituting a = 2 we get
negative sign multiplied by odd number of times then the sign remains negative.
Therefore,
Answer:
D
Step-by-step explanation:
Find out if they match in all of them

Answer:
see explanation
Step-by-step explanation:
Using the Sine rule in all 3 questions
(1)
= , substitute values , firstly calculating ∠ B
[ ∠ B = 180° - (78 + 49)° = 180° - 127° = 53° ]
= ( cross- multiply )
a sin53° = 18 sin78° ( divide both sides by sin53° )
a = ≈ 22.0 ( to the nearest tenth )
(3)
= , substitute values
= ( cross- multiply )
45 sinC = 35 sin134° ( divide both sides by 35 )
sinC = , then
∠ C = ( ) ≈ 34.0° ( to the nearest tenth )
(5)
Calculate the measure of ∠ B
∠ B = 180° - (38 + 92)° = 180° - 130° = 50°
= , substitute values
= ( cross- multiply )
BC sin50° = 10 sin38° ( divide both sides by sin50° )
BC = ≈ 8.0 ( to the nearest tenth )
Respuesta:
29.00
Explicación:
una naranja 3.00
un melón 12.00
una manzana 2.00 (porque una docena equivale 12 artículos; 24/12 es 2)
tres naranjas 3(3.00) = 9.00
un melón 12.00
cuatro manzanas 4(2.00) = 8.00
9.00 +12.00 +8.00
29.00
