Answer: 9
Step-by-step explanation: 90 divided by 10:
You can simplify this by removing the zeros because there are the same amount of zeros in both numbers:
9 divided by 1 is left.
Anything divided by one is itself so 9 divided by 1 is 9
Okay, so the possible numbers he can choose are :
1, 2, 3, 4, 5, 6, 7, 8, 9, 10
Pick out all the odd numbers and multiples of 5.
1, 3, 5, 7, 9, 10
Count how many numbers are odd and are a multiple of 5.
6 numbers are odd or are a multiple of 5.
So, out of 10 numbers, 6 are odd or are a multiple of 5,
Therefore, our answer is 6/10
If you would like it simplified, it would be 3/5
Or, as a decimal, it would be 60%

Answer: 75° is the smallest amount you need to rotate the image for it to look the same.
Step-by-step explanation: I hope it can be correct :))
The factors should add to the b value and multiply to the c value.
Final answer: (x-9)(x-7)
Check:
-9*-7=63
-9-7=-16
Circumference = 2πr
So the circumference of the track is C = 2π .2 or .4π
3 times around the track is .4π x 3 or 1.2π - this is the answer but most teachers will want you to use 3.14 for pi.
so 1.2 x 3.14 = 3.768 km
Do you notice that I waited until the end to use the actual value of pi (3.14) in my calculations.
Keeping things in pi units until the very end saves time.
