Answer:
24 blue cars
Step-by-step explanation:
Let
The ratio of red cars to blue cars in a parking lot was 5:3, that is,
r/b = 5/3
If there were 40 red cars (r = 40),
40/b = 5/3
We use the Cross Products Property of Proportions.
40 × 3 = b × 5
120 = b × 5
b = 120/5
b = 24
There were 24 blue cars.
6
(3x-5)+(2x-1)+(x+1) = 6x-5 = 31
6x = 36
x = 6
1/2
cos(θ) = √(1 -sin(θ)²) = √(1 -3/4) = √(1/4)
cos(θ) = 1/2
