Answer:
3/2 or 1.5
Step-by-step explanation:To find the perimeter you need to multiply the four sides why the same number like: 3/8in(4)wich equal 3/2in or in decimal point 1.5 hope it helps. :)
The expression for the number of segments drawn out of the n number of points in the circle is,
n² / 2 - n / 2
Substituting directly to the expression the number of points, n, which is equal to 8,
8² / 2 - 8 / 2 = 28
Thus, there are 28 segments that can be drawn from the points.
Answer:
5
Step-by-step explanation:
the height 5
the base 2
5*2*1/2 = 5
You replace x by 18 so it becomes f(18)=1.50×18+12.50 and that should give you 39.50
Turn both into improper fractions- there easier to work with that way
3 15/16 — 63/16
2 1/4 — 9/4
Then, set it up- you multiply by the reciprocal
63 Divided by 9
__. __
16. 4
Multiply by reciprocal (flipped-second fraction)
63. x. 4
16 9
Cross product- check to see if diagonally the numbers have similar factors- 63 and 9 have 9 in common, 16 and 4 have 4 in common
7. 1
4. 1
1 3/4
