Let the age of Jay be x years, so age of Jay's father is 2x years .
After 20 years,
Jay's age will be 
And Jay's father age will be 
But at that time, jay's age will be
So we have
Cross multiplication
Therefore Jay's age is 20 years and Jay's Father's age is 40 years .
Make a number line.. Then put 1/6, 2/6, 3/6, 4/6, 5/6, and 6/6 =1
<-------0-------1/6-------2/6-------3/6-------4/6-------5/6-------1------->
Then since 1/2 is half a whole thing put 1/2 ontop of the 3/6 like...
1/2
<-------0-------1/6-------2/6-------3/6-------4/6-------5/6-------1------->
Hope this helps you! :D
Answer:
the answer ios yes
Step-by-step explanation:
55-243 equals the sum of 11
Answer:
12.62
Step-by-step explanation:
imagine a circle with the center at the corner (let's call it A) with the 31 degree angle. the radius is AB.
so,
x = sin(31)×AB
and
21 = cos(31)×AB
therefore,
AB = 21/cos(31) = 24.4993...
=> x = sin(31)×24.4993... = 12.62 (12.61807...)
