Answer:
It is divisible by 11 and (a + b) !
Step-by-step explanation:
Given a two digit number 
, the digits written in reverse order is 
.
Note that a two digit number ab = 10a + b.
For example: 24 = 10(2) + 4
Similarly, ba = 10(b) + a
Now, the sum of the numbers ab and ba = 10a + b + 10b + a
= 11a + 11b
= 11(a + b)
Hence, the sum of any two digit number ab and the reverse of the number ba, is divisible by 11 and (a + b).
Hence, proved.
Answer: 1.64 2.100
Step-by-step explanation:
The reason for this is squaring something is simply mulyiplying the number by itself. for example
8 squared
there is a 2 above the 8 which means we will do 8x8.
8x8= 64
Hope this helps!!!!
Have you heard the expressions "shooting fish in a barrel" or
"taking candy from a baby" ?
I've decided to take your points and try not to feel guilty about it.
A). That's it ! That's the equation, for ANY basketball on Earth.
You wrote it right there in your question.
In that equation that you wrote, the ' r ' is the initial velocity.
You said that Adam tossed it straight up, and it was going 10 meters per second
when it left his hand.
So ' r ' in the equation is +10.
The equation is:
<em>d = 10t - 5t² </em> .
It tells you how high the ball is above its tossing height after any number of seconds.
The ' t ' in the equation is the number of seconds. Any letter could have been used,
but ' t ' was cleverly selected because it stands for 'time'.
B). You want to know where it is after 0.5 second ? All you have to do is put '0.5'
into the equation wherever there's a ' t '. Do you really need somebody to do that
for you ?
Well, OK. You're being so overly generous with your points . . .
Distance = 10 t - 5 t²
Distance = 10 (0.5) - 5 (0.5)²
Distance = 5 - 5(0.25)
Distance = 5 - 1.25
<em>Distance = 3.75 meters </em>
<u>positive</u> 3.75 means <u>above</u> Adam's hand.
A thinking exercise:
-- He tossed the ball upwards at 10 meters per second.
-- Why is it not 5 meters above his hands after 0.5 second?
Answer:
See Below
Step-by-step explanation:
1) 180 ft / 6 sec
You can divide both the numerator and denominator by 6:
30 ft / 1 sec
2) 86 mi/5 hr
You can divide 86 by 5:
17.2 mi / hr
3) 83 mi / 5hr
Same as above ^
16.6 mi / hr --> 16.6 mph
4) 93 feet / 5 sec
Same as above ^^
18.6 ft/ 1 sec
5) 150 mi / 4 hr
Same as above ^^^
37.5 mi / 1 hr --> 37.5 mph
