Answer:
B. $1188
Step-by-step explanation:
If he makes $99 per room, add all the rooms first:
3 + 5 + 4 = 12 rooms total
Then multiply the number of rooms by the price per room:
$99 * 12 = $1188
C is identity
B is associative
A is identity
B is communitative
Answer: 3
Step-by-step explanation:
Set them equal because they are the same so 15x+5=16x+2 so x+2=5 so x=3
45 degrees.
180 degrees in one triangle.
90 is a right angle.
45 for each of the other angles. Add them together you get 90.
Two 90 degree angles will get you a right triangle.
hope this helps
Answer:
a(9) = 150*(0.4)^8 = 0.098304
Step-by-step explanation:
This is a geometric sequence, because each new term is 0.4 times the previous term.
The general formula for a geometric sequence is a(n) = a(1)*r^(n - 1). Here, with a(1) = 150 and r = 0.4, we have:
a(n) = 150*(0.4)^(n - 1), and so
a(9) = 150*(0.4)^8 = 0.098304
