Answer:
50% or 1/2
Step-by-step explanation:
The chance of a coin landing on tails is always 50/50
Let the integers be x-2, x, x+2.
Given,
x -2 + x + x + 2 = 69
3x = 69
x = 23
Hence, the integers are 21, 23 and 25.

Answer:
20 minutes
Step-by-step explanation:
Remember that
![1\ h=60\ mi](https://tex.z-dn.net/?f=1%5C%20h%3D60%5C%20mi)
we know that
Hector has 3/4 hour to spend his homework
Convert to minutes
![\frac{3}{4}(60)=45\ min](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D%2860%29%3D45%5C%20min)
so
1) He wants to spend 1/3 of this time on math homework
To find out the time on math homework, multiply 45 minutes by 1/3
![45(\frac{1}{3})=15\ min](https://tex.z-dn.net/?f=45%28%5Cfrac%7B1%7D%7B3%7D%29%3D15%5C%20min)
2) He wants to spend 10 minutes of his time on reading homework
3) He wants to spend the remaining time on science homework
The time spend on math homework plus the time spend reading homework, plus the time spend on his science homework must be equal to 45 minutes
Let
x ----> the time spend on his science homework
![15+10+x=45](https://tex.z-dn.net/?f=15%2B10%2Bx%3D45)
Solve for x
![25+x=45\\x=45-25\\x=20\ min](https://tex.z-dn.net/?f=25%2Bx%3D45%5C%5Cx%3D45-25%5C%5Cx%3D20%5C%20min)
Answer:
I believe the answer would be 21.
Step-by-step explanation:
the shadow of the tall flag is three times the small flag, so the height of the flag should also be three times the height. which is 21
