Answer:

The probability of the dart hitting the inner circle is 11.2 %.

Step-by-step explanation:

To solve this problem we first need to find the area of the whole target and the area of the smaller target. Since they're both circular, their area is given by the formula:

area = pi*r²

For the whole target:

area target = pi*(6/2)² = 28.26 ft²

For the inner target:

area inner = pi*(2/2)² = 3.14 ft²

The probability that the dart will hit the inner area is:

p = area inner / area target = 3.14 / 28.26 = 0.112

The probability of the dart hitting the inner circle is 11.2 %.

30( \frac{1}{2} x - 2) + 40( \frac{3}{4} y - 4) =  \\

(30 \times  \frac{1}{2} x) -( 30 \times 2 )+ (40 \times  \frac{3}{4} y )- (40 \times 4 )=  \\

15x - 60 + 30y - 160 =  \\

15x + 30y - 220

Find the missing length indicated 144 and 60
Alexxandr [17]

The missing length in the right triangle as given in the task content is; 156.

<h3>What is the missing length indicated?</h3>

It follows from the complete question that the triangle given is a right triangle and the missing length (longest side) can be evaluated by means of the Pythagoras theorem as follows;

x² = 144² + 60²

x² = 20736 + 3600

x² = 24,336

x = √24336

x = 156.

Remarks: The complete question involves a right triangle and the missing length is the longest side.

fiasKO [112]

Hey!

-------------------------------------------------

Solution:

The ratio is FEMALES to MALES.

So its 18/16, 18:16, or 18 to 16.

~Now we need to simplify.

18:16 → 18/2:16/2 → 9:8

*Note* When you have a ratio you need to know which comes first. If you put males to females that incorrect. It has to be correct according to the question.

-------------------------------------------------

Answer:

\large\boxed{B)~9~to~8}
