Answer:
2 digit Multiples of 5 are 10,15,20,25,30,35,40,45,50,55,60,65,70,75,80,85,90,95
Of 7 are 14,21,28,35,42,49,56,63,70,7784,91,98
Step-by-step explanation:
29
For the two digit numbers it has to end in a zero or five and be greater than 9 and below 100.
There are 18 multiples of 5 that are 2 digit
For multiples of 7... it's easier to write it out because the total number will will less than 20.
There are 13 multiples of 7 that are 2 digits
Now you have to subtract the multiples of 7 that end in a 0 or 5
That give you 11 multiples
Add 11 and 18 to get 29
10 Minutes
At roughly 10 minutes, the y-axis meets a point at the x-ais that can be shown as (40,10)
12. 9
12. Using Pythagoras theorem
let shortest distance be = x
8 square + 5 square = x square
64 + 25 = x square
89 = x square
Therefore x = square root of 89
Thus X = 9
please edit your question man
Algebrically the result can be written as -
Let the number be 'x'.
