15. Minutes in 365 days.
First, there are 60 minutes in an hour and 24 hours in a day. So there are 1440 minutes in a day. Multiply that by the 365 days, and you get: 1440 x 365 = 525,600.
16. Not absolutely sure about this one, but i reckon it's 16/31, as there are 16 odd days.
17. Area of a triangle is 1/2 x h x b
Now the two shaded area are = the unshaded area. So it's only one triangle, really. So it's 6 x 8 divided by 2 = 24cm²
18. 82 l in ml = 82,000
8.7-10.3=1.6 you add the 2 and you give one tenth to the ones place and subtract to get your answer
To arrange the slopes we need to take their absolute values.
1. U<span>ndefined slope means a vertical line, so it is going to be steepest.
2.|4/3| = 4/3
3.|-3/2| = 3/2
4. 0 means horizontal line.
</span>From flattest to steepest: 0, -3/2, 4/3, undefined.
35-7 which would equal 28, but that answer wouldn't be exactly correct, as this isn't in correct formation. An equation would be 2x + 7 = 35.
35-7= 28 divided by 2(2x) would equal 14
So Mary is 14 and her sister is 21.
21 + 14 equals 35
