This is the answer -1/6, -3, 1/6, .5,
Sin60 =b/10
<span>√3/2 = b/10
</span>b = <span>√3 / 2 (10)
</span>b = 5<span>√3
</span>
d^2 = 10^2 - (5√3)^2
d^2 = 100 - 75
d^2 = 25
d = 5
sin30 = b/a
1/2 = 5√3 / a
a = 5√3 (2)
a = 10√3
c^2 = (10√3)^2 - (5√3)^2
c^2 = 300 - 75
c^2 = 225
c = 15
so
a =10√3, b = 5√3, c = 15,d = 5
answer is
D. last choice
Answer:
With the increase of the value of a ,the value of the expression 20+a will also increase.
Step-by-step explanation:
Answer:
- 400 adult tickets
- 325 children's tickets
Step-by-step explanation:
Let x represent the number of adult tickets sold. Then 725-x is the number of children's tickets sold, and the total revenue is ...
2.50x +1.50(725 -x) = 1487.50
1.00x + 1087.50 = 1487.50 . . . . . eliminate parentheses
x = 400 . . . . . . . . . . . . . . . . . . . . . subtract 1087.50
There were 400 adult tickets and 325 children's tickets sold.
The answer to this question is:
x = 1 + or - the square root of 47
