Answer:
We can expect 28 defected cars.
Step-by-step explanation:
Let us assume that the defected cars are "uniformly distributed" in the total set of cars.
Then we can write the proportion 8%2F360 = x%2F1260 for the unknown amount x of defected cars among 1260 cars.
Solving the proportion for x you get
x = 8%2A1260%2F360 = 8%2A3.5 = 28.
I think it’s b leetttttt ggggggooo
Answer:
Step-by-step explanation:
∠1 = 38 {Vertically opposite angles}
∠2 = 39 + 36 = 75
Exterior angle equals the sum of opposite interior angles.
x = ∠1 +∠2
= 38 + 75
x = 113
First, we group together the terms with variables in one side by subtracting 3/2 x and 5 from both sides of the equation.
(2/3)x - (3/2)x + 5 - 5 = (3/2)x - (3/2)x - 5
(-5/6)x = -5
The value of x from the equation is 6.
Answer:
Step-by-step explanation:
If the triangle is equilateral :
2x +y/2 = 5x/3+y + ½ = 2/3x +2y +5/2
so the perimeter is : P = 3(2x +y/2) or 3(5x/3+y + ½) or 3(2/3x +2y +5/2)
the simplest is : P = 3(2x +y/2)
P = 6x + (3y)/2
