6:13 =83
6+13=19
1 part=83÷19
=4.37
6×4.4=26.4
13×4.4=57.2
26.4:57.2
p.s I got how much money only...
sorry
Step-by-step explanation:
a) The 3rd row has 37 seats, the 4th row has 45 seats and the 5th row has 53 seats.
b) This is an arithmetic sequence because the values differ by a constant quantity.
c) You need to find the nth term of the sequence:
21 = 1×8+x
x=13
So the nth term is 8x +13.
The 100th term would be 813.
Answer:
- sin(θ) = (-2√13)/13
- cos(θ) = (3√13)/13
- tan(θ) = -2/3
- sec(θ) = (√13)/3
- csc(θ) = (-√13)/2
- cot(θ) = -3/2
Step-by-step explanation:
The distance of the point from the origin is ...
r = √(3² +(-2)²) = √13
We know that ...
x = r·cos(θ) ⇒ cos(θ) = x/r = 3/√13 = (3√13)/13
y = r·sin(θ) ⇒ sin(θ) = y/r = -2/√13 = (-2√13)/13
tan(θ) = sin(θ)/cos(θ) = -2/3
sec(θ) = 1/cos(θ) = (√13)/3
csc(θ) = 1/sin(θ) = (-√13)/2
cot(θ) = 1/tan(θ) = -3/2
Answer:
x>1
x<3
Step-by-step explanation:
For solving inequalities you ignore one part and solve
2<2x
1<x
2x<6
x<3
Answer:
x=28
Step-by-step explanation:
degrees of a triangle is always 180
2x+3x=5x
5x - 10 + 50
5x + 40
180 - 40 = 140
5x = 140
140/5 = 28
