Answer:
42 boys can count (given)
P(boy & can count) = 0.35
Step-by-step explanation:
P(boy who can count) = 42/120
7/20 = 0.35
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
Sen 22° = 
h = 
h = 
h = 297,29 m
Sen 20° = 
h = 
h = 
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.

Answer:
BT=CT the first one because BAT=CAT and bc cut the similar vector between these two triangle
The roof is made up of two mirred right triangles which are congruent. We can find the width by finding the width of one of the triangles then doubling the answer to get the width of the entire roof.
We are given that the slope (rise over run) is 5/12 which means that for every 5 feet of height there is 12 feet of width. We can use this ratio to find the width of one triangle given the height of 8 by setting up the following proportion:
5/12 = 8/x
Solve for x by cross multiplying:
5x = (12)(8)
x = (12)(8)/5
x = 19.2 feet
Multiply by 2 to get the entire width:
(19.2)(2) = 38.4 feet
The answer is 38.4 feet
I think this answer is C the y-coordinate of x is 3
