Both chances to success are 1/4. If you want the first AND the second to be successful, you have to multiply the chances, so the answer is

1/4 * 1/4 = 1/16

Question
David and Brad are competing in a 20-mile bicycle race. David rides 6.2 miles in 1/4 hour. Brad rides 11.9 miles in 1/2 hour. If both riders continue at the same average speed, who will finish first? Explain how you know.
Solution 1
First, you calculate David's and Brad's unit rate.Â

David:

6.2 mi./1/4 hr. = 6.2 m./15 minutesÂ
In an hour, there's 60 minutes. 60 divided by 4 is 15. So 1/4 of an hour is 15 minutes.

11.9 mi./1/2 hr. = 11.9 mi./30 minutes
Once again, there's 60 minutes in an hour, so 1/2 of an hour is 30 minutes.

Okay, observing both of the unit rates, David's speed is just about half of Brad's speed. As a result, you multiply David's unit rate twice to get the same amount of time as Brad. It's easier to solve if you think about fractions since unit rates and fractions are just about the same. Now, multiply both the numerator and denominator by 2:

6.2 x 2 = 12.4, and 15 x 2 = 30
Now that you've multiplied them by two, David and Brad are now continuing at the same average speed.

David: 12.4 mi./30 min.

David will finish the bicycle race first since he's gone farther than Brad.
I reallyÂ hope I helped! :) There are so many other ways to solve this, but here's one way that I know best. If I didn't help, I'm sorry. I tried. :(

Question
explain why in any triangle the difference of the lengths of any two sides cannot be greater that the length of the third side.
Solution 1
Becuase then the 3 lines woul dnot connect
if you draw any 1 line of legnth w
then lets say you draw a line of legnth w/2 and (2/w)-1
then you would have 2 lines that are too short to connect
try it yourself

basically lets say we have sides legnth 3,6,10
10-6 is more than 3
if you draw a line that is 10 legnth and try to draw 1 line at each end, one which is 3 legnth and the other which is 6 legnth, you cannnot connect the 3 and 6 line becuase they are 1 unit too short, if they were 1 unit longer, then the triangle would be a line

Question
Two cyclists leave town at the same time on the same road going in Â the same direction. Cyclist a is going 6 miles per hour faster than cyclist b. After 8 hours, cyclist a has traveled three times the distance as cyclist b. Use the equation 24x= 8(x+6) to find how fast cyclist b was traveling.
Solution 1

3 mph

Step-by-step explanation:

Two cyclists leave town at the same time on the same road going in Â the same direction.

Cyclist A is going 6 mph faster than cyclist B

Let speed of cyclist B be x mph

Speed of cyclist A be (x+6) mph

Both cyclist leave town at the same time and traveled 8 hours. Â

• Distance covered by cyclist A in 8 hours= 8(x+6)
• Distance covered by cyclist B in 8 hours= 8x

After 8 hours cyclist A has traveled 3 times the distance as cyclist B

Therefore, 8(x+6) = 3(8x)

8x + 48 = 24x

24x - 8x = 48

Â  Â  Â  Â 16x = 48

Â  Â  Â  Â  Â  x = 3 mph

Hence, The speed of cyclist B was 3 mph

Solution 2
24x=8x+48
16x=48

Question
one of the congruent angles of an isosceles triangle measures 40 degrees. what measures do the other angles have?
Solution 1
Isosolese triangle has 2 equal angles
3 interior angles of a triangle add upt o 180 so
since 1 of the 2 identical angles are 40 then
40+40+x=180
80+x=180
subtract 80
x=100
the ohter angle is 100

angles=40,40,100
