goldenfox [79]

Answer: She spend $1.20 for lunch.

Step-by-step explanation:

Let the total amount be 'x'.

Half of her money spend for lunch be $\dfrac{x}{2}$

Half of her money left for a movie be $\dfrac{x}{2}$

Amount she has now = $1.20

So, According to question, it becomes ,

$\dfrac{x}{2}=1.20\\\\x=1.20\times 2\\\\x=\$2.40$

Hence, Amount she spend for lunch is $\dfrac{x}{2}=\dfrac{2.40}{2}=\$1.20$

Therefore, she spend $1.20 for lunch.

Which of the following is equal to the expression listed above?

MA_775_DIABLO [31]

Answer:

$(14 + 7) + 12 = 14 + (7 + 12)$

Step-by-step explanation:

Given

$(14 + 7) + 12$ --- [Missing in question]

Required

Select equivalent expression

$(14 + 7) + 12$

Associative property states that:

$(a + b) + c = a + (b + c)$

In this case:

$a = 14$

$b = 7$

$c = 12$

So, we have:

$(a + b) + c = a + (b + c)$

$(14 + 7) + 12 = 14 + (7 + 12)$

B. is correct

Use the given information to determine the exact trigonometric value.

pashok25 [27]

Answer: $\bold{a.\quad -\dfrac{2\sqrt{6}}{5}}$

Step-by-step explanation:

$sin\theta=\dfrac{y}{h}\implies y=-1, h=5\\\\\\\text{Use Pythagorean Theorem to find x:}\\x^2 + y^2 = h^2\\x^2 + (-1)^2=5^2\\x^2+1=25\\x^2=24\\x=\sqrt{24}\\x=2\sqrt{6}$

$\text{Since }\theta\text{ is between }\pi\text{ and }\dfrac{3\pi}{2} \text{ (Quadrant III)},\text{ then x and y are negative.}\\\implies x=-2\sqrt{6}\\\\\\cos\theta = \dfrac{x}{h}\quad =\boxed{-\dfrac{2\sqrt{6}}{5}}$
