Answer:
The probability of a dart hitting the target in the yellow zone is 0.16 or 16%
.
Step-by-step explanation:
Given:
Four concentric circles.
Radius of center circle, r = 4/2 = 2 cm
Radius of the yellow circle, R = 2+4 =6 cm
We have to find the probability that it will hit a point in the yellow region.
Formula to be used:
Probability (P) :
⇒
So,
Lets find the area of the yellow zone;
⇒ Area (yellow zone), = Area of yellow circle - Area of the black circle
⇒
⇒
⇒
⇒
⇒
⇒ cm^2
Now,
⇒ Area of the entire target, A1:
⇒
⇒ <em> ...R1=14 cm</em>
⇒ cm^2
Probability:
⇒
⇒
⇒
⇒
In terms of percentage it is
The probability of a dart hitting the target in the yellow zone is 0.16 or 16%
.
Answer:
<em>Answer: B. x=7</em>
Step-by-step explanation:
<u>Similar Triangles</u>
Assuming the up arrows indicate parallel lines, then triangles PQT and PRS are similar. See the image provided below.
Similar triangles have their side lengths proportional by a constant scale factor. They also have all of their internal angles congruent, or with the same measure.
This means that the marked angles are equal:
2x + 5 = x + 12
Subtracting x
x + 5 = 12
Subtracting 5:
x = 7
Answer: B. x=7
I think its B I’m not really sure
