Answer:

8.5 units

Step-by-step explanation:

first we gotta find the length of the diameter. they made it into a triangle, so we can use pythagorean theorem.

15² + 8² = c²

225 + 64 = c²

289 = c²

17 = c

so now we know that the length of the diameter is 17 units, so the radius would be half of that.

17 ÷ 2 = 8.5

so the radius is 8.5

5. As two boats are coming to the end of a race, a top view of their positions is

Dafna1 [17]

The distance of the boat on the right to the finish line is 297.29 m and the distance of the boat on the left to the finish is 294.11 m, so the boat on the left will reach the finish line faster.

<h3>How do you know which boat will reach the finish line faster? </h3>

The image shows two triangles of which we know an angle and the value of the opposite leg. Therefore, we can perform a mathematical operation to know the value of the hypotenuse of these triangles, which would be the distance of the boats to the goal as shown below.

h = hypotenuse

Right Boat

Sen 22° = $\frac{110 m}{h}$

h = $\frac{110 m}{ Sin 22}$

h = $\frac{110 m}{0.37}$

h = 297,29 m

Left boat

Sen 20° = $\frac{100}{h}$

h = $\frac{|00 m}{ Sin 20}$

h = $\frac{100 m}{0.34}$

h = 294,11 m

According to the above, the distance of the boat on the left is less, so it can be inferred that this boat will reach the finish line faster.

Can some one help me with 18

dimulka [17.4K]

Answer:

82.6%

Step-by-step explanation:

Conditional probability is defined as:

P(A|B) = P(A∩B) / P(B)

where P(A|B) is the probability of A on the condition of B, P(A∩B) is the probability of both A and B, and P(B) is the probability of B.

Here, we want P(P|K), so:

P(P|K) = P(P∩K) / P(K)

P(P|K) = 0.019 / 0.023

P(P|K) = 0.826

Mr. Vargas is buying used computer equipment. He buys 3 keyboards and 4 mice. He spends $42. If the items are all the same price

IgorC [24]

Answer:

Hello.

The answer is $6 each item.

Step-by-step explanation:

If all of the items are the same price, then we have a total of 7 items ( 3 keyboards + 4 mic = 7 items).

So at the end is: 7 items ÷ $42 = $6.
