Answer:
65
Step-by-step explanation:
All the angles in a right triangle add up to 180
plug in what we know and we get
90+25+x=180
115+x=180
x=65
Full price of popcorn: $3.50
Price of popcorn after half the movie: $1.75
price of drinks: $1.35
The question is....."Determine the cost for purchasing 3 orders of popcorn and 3 drinks when the movie is half over."
$1.75*3=$5.25
$1.35*3=$4.05
the price of the 3 orders of popcorn would be $5.25
The price of the 3 orders of drink would be $4.05
5.25 + 4.05 = $9.30
In total the 3 orders of popcorn and 3 orders of drink would cost $9.30
Hope this helps! :)
Answer:x=-5 and x=3
Step-by-step explanation:
log(x^2-15)=log(2x)
Cancel log at both sides we get
x^2-15=2x
Collect like terms
x^2-2x-15=0
x^2-3x+5x-15=0
x(x-3)+5(x-3)=0
(x+5)(x-3)=0
x+5=0 x-3=0
x=-5 x=3

and 
, then the points translated over the x-axis are 
and 
, respectively. The most precise description of the shape is a rectangle for the following facts:
1) 
and 
.
2) 
and 
have the same x-component.
3) 
and 
have the same x-component.
4) and have the same y-component.
5) and have the same y-component.
A representation of the shape is included below as attachment.
