Please I really need help with this

romanna [79]

Answer:

A, 14

Step-by-step explanation:

Assuming that she has a total of d dollars, and spends half of it, then we have 1/2d. She then spends another 6 dollars, and therefore we would subtract. She is left with one dollar.

1/2d-6=1

Working backwards, we can solve for d, her total amount of money:

1/2d=7

d=14

I hope this helps! :)

PLEASE HELP ME!

Leya [2.2K]

Answer:

Step-by-step explanation:

Let number of adult tickets sold be $a$

Let number of children tickets sold be $c$

139 tickets were sold:

we can write:

$a+c=139$

a total sales of $972.00:

we can write:

$5.4c+9.5a=972$

Now solving for $c$ in the first equation and substituting that into 2nd equation, we can solve for $a$ , what we need. So:

$c=139-a\\-------\\5.4c+9.5a=972\\5.4(139-a)+9.5a=972\\750.6-5.4a+9.5a=972\\-5.4a+9.5a=972-750.6\\4.1a=221.4\\a=54$

Hence 54 adult tickets were sold.

The point (3, -4) is on the terminal side of angle Θ, in standard position. What are the values of sine, cosine, and tangent of

julia-pushkina [17]

3=x

-4=y

$a { }^{2} + b {}^{2} = c {}^{2}$

$3 {}^{2} + 4 {}^{2} = c {}^{2}$

$\sqrt{} 25 = \sqrt{c {}^{2} }$

$5 = c$

sin0= 4/5

cos0=3/5

tan0=4/3
