Hey there!
To start, first set up a proportion where x is the cost to make 27 copies:
27/x=150/4.50
Now, solve for x by cross multiplying which should look like this:
27*4.50=x*150
Now simplify and solve for x:
121.5=150x
x=0.81
Therefore, it costs $0.81 to make 27 copies.
Hope this helps!
Answer:
3/4 of the carton has been drank.
Step-by-step explanation:
Given that:
She drank on Monday = 1/3 of carton
She drank on Tuesday = 5/12 of carton
Total fraction drank = 1/3 + 5/12
Taking LCM to make denominators same:
Total fraction drank = 1/3 * 4/4 + 5/12
Total fraction drank = 4/12 + 5/12
Total fraction drank = 9/12
Reducing the obtained answer we get
Total fraction drank = 3/4
So 3/4 of the carton has been drank.

Answer & Step-by-step explanation:
Vertical angles are congruent meaning that these two angles are going to have the same measurement. Since we know this, then we can set up an equation where one angle is equal to the other.
x + 10 = 55
Subtract 10 on both sides of the equation.
x = 45
So, the value of x is 45.
