Answer:
37.6
Step-by-step explanation:
x² = a² + b² - 2ab cos 140°
x² = 20² + 20² - 2(20)(20)(-0.766)
x² = 400 + 400 - 800(-0,766)
x² = 800 - (-612.835)
x² = 800 + 612.835
x² = 1412.835
x =√1412.835 = 37.6
Answer:
<h2>$326.25</h2>
Step-by-step explanation:
The question is incomplete as we were not given to numbers of adults and children, neveherless we can assume some figures and plug it into the expression
say number of adult is 15
and number of chidren is 30
In this problem we are going to the values of adults and children tickets into the expression for the total cost and return the answer, which is the total cost of tickets sold
given the expression
8.75 x+ 6.50y
substituting for x and y we have
8.75(15)+ 6.50(30)=
131.25+195=$326.25
The total cost for 15 adults and 30 children is $326.25
