Answer:
3/8
Step-by-step explanation:
Find the height of the trapezoids
20 - 10 = 10
10/2 = 5
Find the area of the trapezoids
5*(20+10)/2 = 75
The formula for the area of the trapezoid is the height * the bases added together divided by 2
75*2(this is because there are 2 trapezoids) = 150
Put this to proportion of the total area of the dart board
150/
= 150/400 = 3/8
3/8 is the probability that you score 3 points
Answer:
10/11
Step-by-step explanation:
At first we have to swap the fractions to make those fractions into a normal number. Because it will become a multiplication.
4 × (x + 5) < 5 × (3x + 2)
We will multiply the numbers by the brackets.
4x + 20 < 15x + 10
Now we swap the constant and values from left to right side.
4x - 15x < 10 - 20
or, - 11x < -10
If we divide the inequality by a negative number, say - 11, the inequality becomes reverse.
Therefore,
[-11x ÷ (-11)] > [(-10) ÷ (-11)]
or, x > (10/11)

Answer:
a) ∠XWY = 53°
b) ∠XZY = 106°
Step-by-step explanation:
The relationship between the central angle and the arc length is that they're equal. So, if arc XY = 106° this means that ∠XZY = 106°.
The relationship between the central angle ∠XZY and the inscribed angle ∠XWY is that the inscribed angle is half the value of the central one.
So, ∠XWY= ∠XZY/2 = 106/2 = 53
<u>Results:</u>
∠XWY = 53°
∠XZY = 106°
