Let's work on the triangle first. The x intercept of 2y=27-3x is
0 = 27 - 3x
3x = 27
x = 9
So A(9,0)
B is the meet of 2y=27-3x and y=3x
2y=27-y
3y=27
y=9
y is the height of OAB; we don't really need x
Area(OAB) =
Now we have to subtract
Area = 40.5 - 24.3 = 16.2
Answer: 16.2
Answer:
$56 and dependent
Step-by-step explanation:
7 x 3 = 21
7 x 5 = 35
21 + 35 = $56
The total cost would be the dependent variable because the total entrance fee would depend on the amount of people touring.
Hope this helps! :)
Answer:
x=1/2
Step-by-step explanation:
-2x+6-2x-3=1
-4x+3=1
-4x= -2
x=2/4=1/2
Answer: 22.05
Step-by-step explanation:
3 2/3 = 3 10/15
1 3/5 = 1 9/15
1 9/15 + 3 10/15 = 4 19/15 = 5 4/15
5 4/15 - 2 = 3 4/15
6.75 x 3 = 20.25
6.75 x 4/15 = 1.80
1.80 + 20.25 = 22.05
Hope this Helps!
(Let me know if you want me to explain how I did the 4/15 part!)
Answer:
= 3
Step-by-step explanation:
There is a common ratio r between consecutive terms in the sequence, that is
6 ÷ 3 = 12 ÷ 6 = 24 ÷ 12 = 48 ÷ 24 = 2
This indicates the sequence is geometric with n th term
= a₁
where a₁ is the first term and r the common ratio
Here a₁ = 3 and r = 2 , thus
= 3
