Respuesta:
C) impar
Explicación paso a paso:
Solo se puede con un índice impar, ya que al ser negativo su solución no existe en los reales si tiene índice par
Answer:70%

increase in no. of cards=200-60
=140
%change=140/200 x 100
Answer:
Rachel is correct
Step-by-step explanation:
We can calculate angle T by using cosine rule where;
t² = r² + m² - 2rm cos T
From the diagram, we see that;
t = 30
r = 18
m = 24
Thus;
30² = 18² + 24² - 2(18 × 24)cosT
900 = 324 + 576 - 864cosT
864cosT = 900 - 324 - 576
864cosT = 0
cosT = 0/864
T = cos^(-1) 0
T = 90°
Answer:
t=1p
Step-by-step explanation:
this problem is fairly easy. we will first do is set the equation to equal t also known as the total price. this is because you were trying to determine how much you will have to pay if she buys her food in bulk. you will then equal t to how much it will cost if the food is in bulk. to do this you will multiply 1 (this next she wants to buy weighs 1 kg) and multiply it by p (price per kilogram). Hope this helps!
